Types

type Config 

type Config struct {
	// Enables verbose error printing of all credential chain errors.
	// Should be used when wanting to see all errors while attempting to retreive
	// credentials.
	CredentialsChainVerboseErrors *bool

	// The credentials object to use when signing requests. Defaults to
	// a chain of credential providers to search for credentials in environment
	// variables, shared credential file, and EC2 Instance Roles.
	Credentials *credentials.Credentials

	// An optional endpoint URL (hostname only or fully qualified URI)
	// that overrides the default generated endpoint for a client. Set this
	// to `""` to use the default generated endpoint.
	//
	// @note You must still provide a `Region` value when specifying an
	//   endpoint for a client.
	Endpoint *string

	// The region to send requests to. This parameter is required and must
	// be configured globally or on a per-client basis unless otherwise
	// noted. A full list of regions is found in the "Regions and Endpoints"
	// document.
	//
	// @see http://docs.aws.amazon.com/general/latest/gr/rande.html
	//   AWS Regions and Endpoints
	Region *string

	// Set this to `true` to disable SSL when sending requests. Defaults
	// to `false`.
	DisableSSL *bool

	// The HTTP client to use when sending requests. Defaults to
	// `http.DefaultClient`.
	HTTPClient *http.Client

	// An integer value representing the logging level. The default log level
	// is zero (LogOff), which represents no logging. To enable logging set
	// to a LogLevel Value.
	LogLevel *LogLevelType

	// The logger writer interface to write logging messages to. Defaults to
	// standard out.
	Logger Logger

	// The maximum number of times that a request will be retried for failures.
	// Defaults to -1, which defers the max retry setting to the service specific
	// configuration.
	MaxRetries *int

	// Retryer guides how HTTP requests should be retried in case of recoverable failures.
	//
	// When nil or the value does not implement the request.Retryer interface,
	// the request.DefaultRetryer will be used.
	//
	// When both Retryer and MaxRetries are non-nil, the former is used and
	// the latter ignored.
	//
	// To set the Retryer field in a type-safe manner and with chaining, use
	// the request.WithRetryer helper function:
	//
	//   cfg := request.WithRetryer(aws.NewConfig(), myRetryer)
	//
	Retryer RequestRetryer

	// Disables semantic parameter validation, which validates input for missing
	// required fields and/or other semantic request input errors.
	DisableParamValidation *bool

	// Disables the computation of request and response checksums, e.g.,
	// CRC32 checksums in Amazon DynamoDB.
	DisableComputeChecksums *bool

	// Set this to `true` to force the request to use path-style addressing,
	// i.e., `http://s3.amazonaws.com/BUCKET/KEY`. By default, the S3 client will
	// use virtual hosted bucket addressing when possible
	// (`http://BUCKET.s3.amazonaws.com/KEY`).
	//
	// @note This configuration option is specific to the Amazon S3 service.
	// @see http://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html
	//   Amazon S3: Virtual Hosting of Buckets
	S3ForcePathStyle *bool

	// Set this to `true` to disable the SDK adding the `Expect: 100-Continue`
	// header to PUT requests over 2MB of content. 100-Continue instructs the
	// HTTP client not to send the body until the service responds with a
	// `continue` status. This is useful to prevent sending the request body
	// until after the request is authenticated, and validated.
	//
	// http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html
	//
	// 100-Continue is only enabled for Go 1.6 and above. See `http.Transport`'s
	// `ExpectContinueTimeout` for information on adjusting the continue wait timeout.
	// https://golang.org/pkg/net/http/#Transport
	//
	// You should use this flag to disble 100-Continue if you experiance issues
	// with proxies or thrid party S3 compatible services.
	S3Disable100Continue *bool

	// Set this to `true` to enable S3 Accelerate feature. For all operations compatible
	// with S3 Accelerate will use the accelerate endpoint for requests. Requests not compatible
	// will fall back to normal S3 requests.
	//
	// The bucket must be enable for accelerate to be used with S3 client with accelerate
	// enabled. If the bucket is not enabled for accelerate an error will be returned.
	// The bucket name must be DNS compatible to also work with accelerate.
	S3UseAccelerate *bool

	// Set this to `true` to disable the EC2Metadata client from overriding the
	// default http.Client's Timeout. This is helpful if you do not want the EC2Metadata
	// client to create a new http.Client. This options is only meaningful if you're not
	// already using a custom HTTP client with the SDK. Enabled by default.
	//
	// Must be set and provided to the session.New() in order to disable the EC2Metadata
	// overriding the timeout for default credentials chain.
	//
	// Example:
	//    sess := session.New(aws.NewConfig().WithEC2MetadataDiableTimeoutOverride(true))
	//    svc := s3.New(sess)
	//
	EC2MetadataDisableTimeoutOverride *bool
