Functions

func BuildTLSConfig added in v1.8.0 

func BuildTLSConfig(tlsOpts map[string]interface{}) (*tls.Config, error)

BuildTLSConfig specifies tls.Config options for each KMS provider to use to configure TLS on all connections created to the KMS provider. The input map should contain a mapping from each KMS provider to a document containing the necessary options, as follows: 

{
		"kmip": {
			"tlsCertificateKeyFile": "foo.pem",
			"tlsCAFile": "fooCA.pem"
		}
}

Currently, the following TLS options are supported:

1. "tlsCertificateKeyFile" (or "sslClientCertificateKeyFile"): The "tlsCertificateKeyFile" option specifies a path to the client certificate and private key, which must be concatenated into one file.

2. "tlsCertificateKeyFilePassword" (or "sslClientCertificateKeyPassword"): Specify the password to decrypt the client private key file (e.g. "tlsCertificateKeyFilePassword=password").

3. "tlsCaFile" (or "sslCertificateAuthorityFile"): Specify the path to a single or bundle of certificate authorities to be considered trusted when making a TLS connection (e.g. "tlsCaFile=/path/to/caFile").

This should only be used to set custom TLS options. By default, the connection will use an empty tls.Config{} with MinVersion set to tls.VersionTLS12.

Types

type AggregateOptions added in v0.1.0 

type AggregateOptions struct {
	// If true, the operation can write to temporary files in the _tmp subdirectory of the database directory path on
	// the server. The default value is false.
	AllowDiskUse *bool

	// The maximum number of documents to be included in each batch returned by the server.
	BatchSize *int32

	// If true, writes executed as part of the operation will opt out of document-level validation on the server. This
	// option is valid for MongoDB versions >= 3.2 and is ignored for previous server versions. The default value is
	// false. See https://www.mongodb.com/docs/manual/core/schema-validation/ for more information about document
	// validation.
	BypassDocumentValidation *bool

	// Specifies a collation to use for string comparisons during the operation. This option is only valid for MongoDB
	// versions >= 3.4. For previous server versions, the driver will return an error if this option is used. The
	// default value is nil, which means the default collation of the collection will be used.
	Collation *Collation

	// The maximum amount of time that the query can run on the server. The default value is nil, meaning that there
	// is no time limit for query execution.
	//
	// NOTE(benjirewis): MaxTime will be deprecated in a future release. The more general Timeout option may be used
	// in its place to control the amount of time that a single operation can run before returning an error. MaxTime
	// is ignored if Timeout is set on the client.
	MaxTime *time.Duration

	// The maximum amount of time that the server should wait for new documents to satisfy a tailable cursor query.
	// This option is only valid for MongoDB versions >= 3.2 and is ignored for previous server versions.

	// The default is nil, which means that no comment will be included in the logs.
	Comment *string

	// The index to use for the aggregation. This should either be the index name as a string or the index specification
	// as a document. The hint does not apply to $lookup and $graphLookup aggregation stages. The driver will return an
	// error if the hint parameter is a multi-key map. The default value is nil, which means that no hint will be sent.
	Hint interface{}

	// Specifies parameters for the aggregate expression. This option is only valid for MongoDB versions >= 5.0. Older
	// servers will report an error for using this option. This must be a document mapping parameter names to values.
	// Values must be constant or closed expressions that do not reference document fields. Parameters can then be
	// accessed as variables in an aggregate expression context (e.g. "$$var").
	Let interface{}

	// Custom options to be added to aggregate expression. Key-value pairs of the BSON map should correlate with desired
	// option names and values. Values must be Marshalable. Custom options may conflict with non-custom options, and custom
	// options bypass client-side validation. Prefer using non-custom options where possible.
	Custom bson.M

	EncryptedFieldsMap    map[string]interface{}
	BypassQueryAnalysis   *bool
}

AutoEncryptionOptions represents options used to configure auto encryption/decryption behavior for a mongo.Client instance.

Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view, and operations that are not bypassed will result in error. Too bypass automatic encryption for all operations, set BypassAutoEncryption=true.

Auto encryption requires the authenticated user to have the listCollections privilege action.

If automatic encryption fails on an operation, use a MongoClient configured with bypassAutoEncryption=true and use ClientEncryption.encrypt() to manually encrypt values.

Enabling Client Side Encryption reduces the maximum document and message size (using a maxBsonObjectSize of 2MiB and maxMessageSizeBytes of 6MB) and may have a negative performance impact.

func AutoEncryption added in v1.2.0 

func AutoEncryption() *AutoEncryptionOptions

AutoEncryption creates a new AutoEncryptionOptions configured with default values.

func MergeAutoEncryptionOptions deprecated added in v1.2.0 

func MergeAutoEncryptionOptions(opts ...*AutoEncryptionOptions) *AutoEncryptionOptions

MergeAutoEncryptionOptions combines the argued AutoEncryptionOptions in a last-one wins fashion.

Deprecated: Merging options structs will not be supported in Go Driver 2.0. Users should create a single options struct instead.

func (*AutoEncryptionOptions) SetBypassAutoEncryption added in v1.2.0 

func (a *AutoEncryptionOptions) SetBypassAutoEncryption(bypass bool) *AutoEncryptionOptions

SetBypassAutoEncryption specifies whether or not auto encryption should be done.

If this is unset or false and target mongo.Client being configured has an unlimited connection pool size (i.e. maxPoolSize=0), it is reused in the process of auto encryption. Otherwise, if the target mongo.Client has a limited connection pool size, a separate internal mongo.Client is used (and created if necessary). The internal mongo.Client may be shared for key vault operations (if KeyVaultClient is unset). The internal mongo.Client is configured with the same options as the target mongo.Client except minPoolSize is set to 0 and AutoEncryptionOptions is omitted.

func (*AutoEncryptionOptions) SetBypassQueryAnalysis added in v1.10.0 

func (a *AutoEncryptionOptions) SetBypassQueryAnalysis(bypass bool) *AutoEncryptionOptions

SetBypassQueryAnalysis specifies whether or not query analysis should be used for automatic encryption. Use this option when using explicit encryption with Queryable Encryption.

func (*AutoEncryptionOptions) SetEncryptedFieldsMap added in v1.10.0 

func (a *AutoEncryptionOptions) SetEncryptedFieldsMap(ef map[string]interface{}) *AutoEncryptionOptions

SetEncryptedFieldsMap specifies a map from namespace to local EncryptedFieldsMap document. EncryptedFieldsMap is used for Queryable Encryption.

func (*AutoEncryptionOptions) SetExtraOptions added in v1.2.0 

func (a *AutoEncryptionOptions) SetExtraOptions(extraOpts map[string]interface{}) *AutoEncryptionOptions

SetExtraOptions specifies a map of options to configure the mongocryptd process or mongo_crypt shared library.

Supported Extra Options

"mongocryptdURI" - The mongocryptd URI. Allows setting a custom URI used to communicate with the mongocryptd process. The default is "mongodb://localhost:27020", which works with the default mongocryptd process spawned by the Client. Must be a string.

"mongocryptdBypassSpawn" - If set to true, the Client will not attempt to spawn a mongocryptd process. Must be a bool.

"mongocryptdSpawnPath" - The path used when spawning mongocryptd. Defaults to empty string and spawns mongocryptd from system path. Must be a string.

"mongocryptdSpawnArgs" - Command line arguments passed when spawning mongocryptd. Defaults to ["--idleShutdownTimeoutSecs=60"]. Must be an array of strings.

"cryptSharedLibRequired" - If set to true, Client creation will return an error if the crypt_shared library is not loaded. If unset or set to false, Client creation will not return an error if the crypt_shared library is not loaded. The default is unset. Must be a bool.

"cryptSharedLibPath" - The crypt_shared library override path. This must be the path to the crypt_shared dynamic library file (for example, a .so, .dll, or .dylib file), not the directory that contains it. If the override path is a relative path, it will be resolved relative to the working directory of the process. If the override path is a relative path and the first path component is the literal string "$ORIGIN", the "$ORIGIN" component will be replaced by the absolute path to the directory containing the linked libmongocrypt library. Setting an override path disables the default system library search path. If an override path is specified but the crypt_shared library cannot be loaded, Client creation will return an error. Must be a string.

func (*AutoEncryptionOptions) SetKeyVaultClientOptions added in v1.2.0 

func (a *AutoEncryptionOptions) SetKeyVaultClientOptions(opts *ClientOptions) *AutoEncryptionOptions

SetKeyVaultClientOptions specifies options for the client used to communicate with the key vault collection.

If this is set, it is used to create an internal mongo.Client. Otherwise, if the target mongo.Client being configured has an unlimited connection pool size (i.e. maxPoolSize=0), it is reused to interact with the key vault collection. Otherwise, if the target mongo.Client has a limited connection pool size, a separate internal mongo.Client is used (and created if necessary). The internal mongo.Client may be shared during automatic encryption (if BypassAutomaticEncryption is false). The internal mongo.Client is configured with the same options as the target mongo.Client except minPoolSize is set to 0 and AutoEncryptionOptions is omitted.

func (*AutoEncryptionOptions) SetKeyVaultNamespace added in v1.2.0 

func (a *AutoEncryptionOptions) SetKeyVaultNamespace(ns string) *AutoEncryptionOptions

SetKeyVaultNamespace specifies the namespace of the key vault collection. This is required.

func (*AutoEncryptionOptions) SetKmsProviders added in v1.2.0 

func (a *AutoEncryptionOptions) SetKmsProviders(providers map[string]map[string]interface{}) *AutoEncryptionOptions

SetKmsProviders specifies options for KMS providers. This is required.

func (*AutoEncryptionOptions) SetSchemaMap added in v1.2.0 

func (a *AutoEncryptionOptions) SetSchemaMap(schemaMap map[string]interface{}) *AutoEncryptionOptions

SetSchemaMap specifies a map from namespace to local schema document. Schemas supplied in the schemaMap only apply to configuring automatic encryption for client side encryption. Other validation rules in the JSON schema will not be enforced by the driver and will result in an error.

Supplying a schemaMap provides more security than relying on JSON Schemas obtained from the server. It protects against a malicious server advertising a false JSON Schema, which could trick the client into sending unencrypted data that should be encrypted.

func (*AutoEncryptionOptions) SetTLSConfig added in v1.8.0 

func (a *AutoEncryptionOptions) SetTLSConfig(tlsOpts map[string]*tls.Config) *AutoEncryptionOptions

SetTLSConfig specifies tls.Config instances for each KMS provider to use to configure TLS on all connections created to the KMS provider.

This should only be used to set custom TLS configurations. By default, the connection will use an empty tls.Config{} with MinVersion set to tls.VersionTLS12.

type BSONOptions added in v1.12.0 

type BSONOptions struct {
	// UseJSONStructTags causes the driver to fall back to using the "json"

	// minimum BSON int size (either 32 or 64 bits) that can represent the
	// integer value.
	IntMinSize bool

	// NilMapAsEmpty causes the driver to marshal nil Go maps as empty BSON
	// documents instead of BSON null.
	//
	// Empty BSON documents take up slightly more space than BSON null, but
	// preserve the ability to use document update operations like "$set" that
	// do not work on BSON null.
	NilMapAsEmpty bool

	// NilSliceAsEmpty causes the driver to marshal nil Go slices as empty BSON
	// arrays instead of BSON null.
	//
	// Empty BSON arrays take up slightly more space than BSON null, but
	// preserve the ability to use array update operations like "$push" or
	// "$addToSet" that do not work on BSON null.
	NilSliceAsEmpty bool

	// NilByteSliceAsEmpty causes the driver to marshal nil Go byte slices as
	// empty BSON binary values instead of BSON null.
	NilByteSliceAsEmpty bool

	// OmitZeroStruct causes the driver to consider the zero value for a struct
	// (e.g. MyStruct{}) as empty and omit it from the marshaled BSON when the
	// "omitempty" struct tag option is set.
	OmitZeroStruct bool

	// StringifyMapKeysWithFmt causes the driver to convert Go map keys to BSON
	// document field name strings using fmt.Sprint instead of the default
	// string conversion logic.
	StringifyMapKeysWithFmt bool

	// AllowTruncatingDoubles causes the driver to truncate the fractional part
	// of BSON "double" values when attempting to unmarshal them into a Go
	// integer (int, int8, int16, int32, or int64) struct field. The truncation
	// logic does not apply to BSON "decimal128" values.
	AllowTruncatingDoubles bool

	// BinaryAsSlice causes the driver to unmarshal BSON binary field values
	// that are the "Generic" or "Old" BSON binary subtype as a Go byte slice
	// instead of a primitive.Binary.
	BinaryAsSlice bool

	// DefaultDocumentD causes the driver to always unmarshal documents into the
	// primitive.D type. This behavior is restricted to data typed as
	// "interface{}" or "map[string]interface{}".
	DefaultDocumentD bool

	// DefaultDocumentM causes the driver to always unmarshal documents into the
	// primitive.M type. This behavior is restricted to data typed as
	// "interface{}" or "map[string]interface{}".
	DefaultDocumentM bool

	// UseLocalTimeZone causes the driver to unmarshal time.Time values in the
	// local timezone instead of the UTC timezone.
	UseLocalTimeZone bool

	// ZeroMaps causes the driver to delete any existing values from Go maps in
	// the destination value before unmarshaling BSON documents into them.
	ZeroMaps bool

	// ZeroStructs causes the driver to delete any existing values from Go
	// structs in the destination value before unmarshaling BSON documents into
	// them.
	ZeroStructs bool
}

BSONOptions are optional BSON marshaling and unmarshaling behaviors.

ClientOptions contains options to configure a Client instance. Each option can be set through setter functions. See documentation for each setter function for an explanation of the option.

func Client added in v0.1.0 

func Client() *ClientOptions

Client creates a new ClientOptions instance.

func MergeClientOptions deprecated added in v0.1.0 

func MergeClientOptions(opts ...*ClientOptions) *ClientOptions

MergeClientOptions combines the given *ClientOptions into a single *ClientOptions in a last one wins fashion. The specified options are merged with the existing options on the client, with the specified options taking precedence.

Deprecated: Merging options structs will not be supported in Go Driver 2.0. Users should create a single options struct instead.

func (*ClientOptions) ApplyURI added in v1.0.0 

func (c *ClientOptions) ApplyURI(uri string) *ClientOptions

ApplyURI parses the given URI and sets options accordingly. The URI can contain host names, IPv4/IPv6 literals, or an SRV record that will be resolved when the Client is created. When using an SRV record, TLS support is implictly enabled. Specify the "tls=false" URI option to override this.

If the connection string contains any options that have previously been set, it will overwrite them. Options that correspond to multiple URI parameters, such as WriteConcern, will be completely overwritten if any of the query parameters are specified. If an option is set on ClientOptions after this method is called, that option will override any option applied via the connection string.

If the URI format is incorrect or there are conflicting options specified in the URI an error will be recorded and can be retrieved by calling Validate.

For more information about the URI format, see https://www.mongodb.com/docs/manual/reference/connection-string/. See mongo.Connect documentation for examples of using URIs for different Client configurations.

func (*ClientOptions) GetURI added in v1.3.1 

func (c *ClientOptions) GetURI() string

GetURI returns the original URI used to configure the ClientOptions instance. If ApplyURI was not called during construction, this returns "".

func (*ClientOptions) SetAppName added in v0.1.0 

func (c *ClientOptions) SetAppName(s string) *ClientOptions

SetAppName specifies an application name that is sent to the server when creating new connections. It is used by the server to log connection and profiling information (e.g. slow query logs). This can also be set through the "appName" URI option (e.g "appName=example_application"). The default is empty, meaning no app name will be sent.

func (*ClientOptions) SetAuth added in v0.1.0 

func (c *ClientOptions) SetAuth(auth Credential) *ClientOptions

SetAuth specifies a Credential containing options for configuring authentication. See the options.Credential documentation for more information about Credential fields. The default is an empty Credential, meaning no authentication will be configured.

SetBSONOptions configures optional BSON marshaling and unmarshaling behavior.

func (*ClientOptions) SetCompressors added in v1.0.0 

func (c *ClientOptions) SetCompressors(comps []string) *ClientOptions

SetCompressors sets the compressors that can be used when communicating with a server. Valid values are:

1. "snappy" - requires server version >= 3.4

2. "zlib" - requires server version >= 3.6

3. "zstd" - requires server version >= 4.2, and driver version >= 1.2.0 with cgo support enabled or driver version >= 1.3.0 without cgo.

If this option is specified, the driver will perform a negotiation with the server to determine a common list of of compressors and will use the first one in that list when performing operations. See https://www.mongodb.com/docs/manual/reference/program/mongod/#cmdoption-mongod-networkmessagecompressors for more information about configuring compression on the server and the server-side defaults.

This can also be set through the "compressors" URI option (e.g. "compressors=zstd,zlib,snappy"). The default is an empty slice, meaning no compression will be enabled.

func (*ClientOptions) SetConnectTimeout added in v0.1.0 

func (c *ClientOptions) SetConnectTimeout(d time.Duration) *ClientOptions

SetConnectTimeout specifies a timeout that is used for creating connections to the server. This can be set through ApplyURI with the "connectTimeoutMS" (e.g "connectTimeoutMS=30") option. If set to 0, no timeout will be used. The default is 30 seconds.

func (*ClientOptions) SetDialer added in v0.1.0 

func (c *ClientOptions) SetDialer(d ContextDialer) *ClientOptions

SetDialer specifies a custom ContextDialer to be used to create new connections to the server. This method overrides the default net.Dialer, so dialer options such as Timeout, KeepAlive, Resolver, etc can be set. See https://golang.org/pkg/net/#Dialer for more information about the net.Dialer type.

func (*ClientOptions) SetDirect added in v1.0.0 

func (c *ClientOptions) SetDirect(b bool) *ClientOptions

SetDirect specifies whether or not a direct connect should be made. If set to true, the driver will only connect to the host provided in the URI and will not discover other hosts in the cluster. This can also be set through the "directConnection" URI option. This option cannot be set to true if multiple hosts are specified, either through ApplyURI or SetHosts, or an SRV URI is used.

As of driver version 1.4, the "connect" URI option has been deprecated and replaced with "directConnection". The "connect" URI option has two values:

1. "connect=direct" for direct connections. This corresponds to "directConnection=true".

2. "connect=automatic" for automatic discovery. This corresponds to "directConnection=false"

If the "connect" and "directConnection" URI options are both specified in the connection string, their values must not conflict. Direct connections are not valid if multiple hosts are specified or an SRV URI is used. The default value for this option is false.

func (*ClientOptions) SetDisableOCSPEndpointCheck added in v1.4.0 

func (c *ClientOptions) SetDisableOCSPEndpointCheck(disableCheck bool) *ClientOptions

SetDisableOCSPEndpointCheck specifies whether or not the driver should reach out to OCSP responders to verify the certificate status for certificates presented by the server that contain a list of OCSP responders.

If set to true, the driver will verify the status of the certificate using a response stapled by the server, if there is one, but will not send an HTTP request to any responders if there is no staple. In this case, the driver will continue the connection even though the certificate status is not known.

This can also be set through the tlsDisableOCSPEndpointCheck URI option. Both this URI option and tlsInsecure must not be set at the same time and will error if they are. The default value is false.

func (*ClientOptions) SetHTTPClient added in v1.11.0 

func (c *ClientOptions) SetHTTPClient(client *http.Client) *ClientOptions

SetHTTPClient specifies the http.Client to be used for any HTTP requests.

This should only be used to set custom HTTP client configurations. By default, the connection will use an httputil.DefaultHTTPClient.

func (*ClientOptions) SetHeartbeatInterval added in v0.1.0 

func (c *ClientOptions) SetHeartbeatInterval(d time.Duration) *ClientOptions

SetHeartbeatInterval specifies the amount of time to wait between periodic background server checks. This can also be set through the "heartbeatIntervalMS" URI option (e.g. "heartbeatIntervalMS=10000"). The default is 10 seconds.

func (*ClientOptions) SetHosts added in v0.1.0 

func (c *ClientOptions) SetHosts(s []string) *ClientOptions

SetHosts specifies a list of host names or IP addresses for servers in a cluster. Both IPv4 and IPv6 addresses are supported. IPv6 literals must be enclosed in '[]' following RFC-2732 syntax.

Hosts can also be specified as a comma-separated list in a URI. For example, to include "localhost:27017" and "localhost:27018", a URI could be "mongodb://localhost:27017,localhost:27018". The default is ["localhost:27017"]

func (*ClientOptions) SetLoadBalanced added in v1.6.0 

func (c *ClientOptions) SetLoadBalanced(lb bool) *ClientOptions

SetLoadBalanced specifies whether or not the MongoDB deployment is hosted behind a load balancer. This can also be set through the "loadBalanced" URI option. The driver will error during Client configuration if this option is set to true and one of the following conditions are met:

1. Multiple hosts are specified, either via the ApplyURI or SetHosts methods. This includes the case where an SRV URI is used and the SRV record resolves to multiple hostnames. 2. A replica set name is specified, either via the URI or the SetReplicaSet method. 3. The options specify whether or not a direct connection should be made, either via the URI or the SetDirect method.

The default value is false.

func (*ClientOptions) SetLocalThreshold added in v0.1.0 

func (c *ClientOptions) SetLocalThreshold(d time.Duration) *ClientOptions

SetLocalThreshold specifies the width of the 'latency window': when choosing between multiple suitable servers for an operation, this is the acceptable non-negative delta between shortest and longest average round-trip times. A server within the latency window is selected randomly. This can also be set through the "localThresholdMS" URI option (e.g. "localThresholdMS=15000"). The default is 15 milliseconds.

func (*ClientOptions) SetLoggerOptions added in v1.12.0 

func (c *ClientOptions) SetLoggerOptions(opts *LoggerOptions) *ClientOptions

SetLoggerOptions specifies a LoggerOptions containing options for configuring a logger.

		Logger().
		SetSink(sink).
		SetMaxDocumentLength(25).
		SetComponentLevel(options.LogComponentCommand, options.LogLevelDebug)

	clientOptions := options.
		Client().
		ApplyURI("mongodb://localhost:27017").
		SetLoggerOptions(loggerOptions)

	client, err := mongo.Connect(context.TODO(), clientOptions)

	if err != nil {
		log.Fatalf("error connecting to MongoDB: %v", err)
	}

	defer client.Disconnect(context.TODO())

	// Make a database request to test our logging solution.
	coll := client.Database("test").Collection("test")

	_, err = coll.InsertOne(context.TODO(), map[string]string{"foo": "bar"})
	if err != nil {
		log.Fatalf("InsertOne failed: %v", err)
	}

	// Print the logs.
	fmt.Println(buf.String())
}

func (*ClientOptions) SetReplicaSet added in v0.1.0 

func (c *ClientOptions) SetReplicaSet(s string) *ClientOptions

SetReplicaSet specifies the replica set name for the cluster. If specified, the cluster will be treated as a replica set and the driver will automatically discover all servers in the set, starting with the nodes specified through ApplyURI or SetHosts. All nodes in the replica set must have the same replica set name, or they will not be considered as part of the set by the Client. This can also be set through the "replicaSet" URI option (e.g. "replicaSet=replset"). The default is empty.

func (*ClientOptions) SetRetryReads added in v1.2.0 

func (c *ClientOptions) SetRetryReads(b bool) *ClientOptions

SetRetryReads specifies whether supported read operations should be retried once on certain errors, such as network errors.

Supported operations are Find, FindOne, Aggregate without a $out stage, Distinct, CountDocuments, EstimatedDocumentCount, Watch (for Client, Database, and Collection), ListCollections, and ListDatabases. Note that operations run through RunCommand are not retried.

This option requires server version >= 3.6 and driver version >= 1.1.0. The default is true.

func (*ClientOptions) SetRetryWrites added in v0.1.0 

func (c *ClientOptions) SetRetryWrites(b bool) *ClientOptions

SetRetryWrites specifies whether supported write operations should be retried once on certain errors, such as network errors.

Supported operations are InsertOne, UpdateOne, ReplaceOne, DeleteOne, FindOneAndDelete, FindOneAndReplace, FindOneAndDelete, InsertMany, and BulkWrite. Note that BulkWrite requests must not include UpdateManyModel or DeleteManyModel instances to be considered retryable. Unacknowledged writes will not be retried, even if this option is set to true.

This option requires server version >= 3.6 and a replica set or sharded cluster and will be ignored for any other cluster type. This can also be set through the "retryWrites" URI option (e.g. "retryWrites=true"). The default is true.

func (*ClientOptions) SetSRVMaxHosts added in v1.8.0 

func (c *ClientOptions) SetSRVMaxHosts(srvMaxHosts int) *ClientOptions

SetSRVMaxHosts specifies the maximum number of SRV results to randomly select during polling. To limit the number of hosts selected in SRV discovery, this function must be called before ApplyURI. This can also be set through the "srvMaxHosts" URI option.

func (*ClientOptions) SetSRVServiceName added in v1.8.0 

func (c *ClientOptions) SetSRVServiceName(srvName string) *ClientOptions

func (c *ClientOptions) SetServerSelectionTimeout(d time.Duration) *ClientOptions

SetServerSelectionTimeout specifies how long the driver will wait to find an available, suitable server to execute an operation. This can also be set through the "serverSelectionTimeoutMS" URI option (e.g. "serverSelectionTimeoutMS=30000"). The default value is 30 seconds.

func (*ClientOptions) SetSocketTimeout added in v0.1.0 

func (c *ClientOptions) SetSocketTimeout(d time.Duration) *ClientOptions

SetSocketTimeout specifies how long the driver will wait for a socket read or write to return before returning a network error. This can also be set through the "socketTimeoutMS" URI option (e.g. "socketTimeoutMS=1000"). The default value is 0, meaning no timeout is used and socket operations can block indefinitely.

NOTE(benjirewis): SocketTimeout will be deprecated in a future release. The more general Timeout option may be used in its place to control the amount of time that a single operation can run before returning an error. Setting SocketTimeout and Timeout on a single client will result in undefined behavior.

func (*ClientOptions) SetTLSConfig added in v1.0.0 

func (c *ClientOptions) SetTLSConfig(cfg *tls.Config) *ClientOptions

SetTLSConfig specifies a tls.Config instance to use use to configure TLS on all connections created to the cluster. This can also be set through the following URI options:

1. "tls" (or "ssl"): Specify if TLS should be used (e.g. "tls=true").

2. Either "tlsCertificateKeyFile" (or "sslClientCertificateKeyFile") or a combination of "tlsCertificateFile" and "tlsPrivateKeyFile". The "tlsCertificateKeyFile" option specifies a path to the client certificate and private key, which must be concatenated into one file. The "tlsCertificateFile" and "tlsPrivateKey" combination specifies separate paths to the client certificate and private key, respectively. Note that if "tlsCertificateKeyFile" is used, the other two options must not be specified. Only the subject name of the first certificate is honored as the username for X509 auth in a file with multiple certs.

3. "tlsCertificateKeyFilePassword" (or "sslClientCertificateKeyPassword"): Specify the password to decrypt the client private key file (e.g. "tlsCertificateKeyFilePassword=password").

4. "tlsCaFile" (or "sslCertificateAuthorityFile"): Specify the path to a single or bundle of certificate authorities to be considered trusted when making a TLS connection (e.g. "tlsCaFile=/path/to/caFile").

5. "tlsInsecure" (or "sslInsecure"): Specifies whether or not certificates and hostnames received from the server should be validated. If true (e.g. "tlsInsecure=true"), the TLS library will accept any certificate presented by the server and any host name in that certificate. Note that setting this to true makes TLS susceptible to man-in-the-middle attacks and should only be done for testing.

The default is nil, meaning no TLS will be enabled.

func (*ClientOptions) SetTimeout added in v1.10.0 

func (c *ClientOptions) SetTimeout(d time.Duration) *ClientOptions

SetTimeout specifies the amount of time that a single operation run on this Client can execute before returning an error. The deadline of any operation run through the Client will be honored above any Timeout set on the Client; Timeout will only be honored if there is no deadline on the operation Context. Timeout can also be set through the "timeoutMS" URI option (e.g. "timeoutMS=1000"). The default value is nil, meaning operations do not inherit a timeout from the Client.

If any Timeout is set (even 0) on the Client, the values of MaxTime on operation options, TransactionOptions.MaxCommitTime and SessionOptions.DefaultMaxCommitTime will be ignored. Setting Timeout and SocketTimeout or WriteConcern.wTimeout will result in undefined behavior.

NOTE(benjirewis): SetTimeout represents unstable, provisional API. The behavior of the driver when a Timeout is specified is subject to change.

2. "wTimeoutMS": Specify how long write operations should wait for the correct number of nodes to acknowledge the operation (e.g. "wTimeoutMS=1000").

3. "journal": Specifies whether or not write operations should be written to an on-disk journal on the server before returning (e.g. "journal=true").

The default is nil, meaning the server will use its configured default.

Username: the username for authentication. This can also be set through the URI as a username:password pair before the first @ character. For example, a URI for user "user", password "pwd", and host "localhost:27017" would be "mongodb://user:pwd@localhost:27017". This is optional for X509 authentication and will be extracted from the client certificate if not specified.

Password: the password for authentication. This must not be specified for X509 and is optional for GSSAPI authentication.

PasswordSet: For GSSAPI, this must be true if a password is specified, even if the password is the empty string, and false if no password is specified, indicating that the password should be taken from the context of the running process. For other mechanisms, this field is ignored.

The user must specify a ServerAPIVersion if including ServerAPIOptions in their client. That version must also be currently supported by the driver. This version of the driver supports API version "1".
