Documentation

Overview

Package digitalassetlinks provides access to the Digital Asset Links API.

For product documentation, see: https://developers.google.com/digital-asset-links/

Creating a client

Usage example: 

import "google.golang.org/api/digitalassetlinks/v1"
...
ctx := context.Background()
digitalassetlinksService, err := digitalassetlinks.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey: 

digitalassetlinksService, err := digitalassetlinks.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource: 

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
digitalassetlinksService, err := digitalassetlinks.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

Types

type AndroidAppAsset 

type AndroidAppAsset struct {
	// Certificate: Because there is no global enforcement of package name
	// uniqueness, we also
	// require a signing certificate, which in combination with the package
	// name
	// uniquely identifies an app.
	//
	// Some apps' signing keys are rotated, so they may be signed by
	// different
	// keys over time.  We treat these as distinct assets, since we use
	// (package
	// name, cert) as the unique ID.  This should not normally pose any
	// problems
	// as both versions of the app will make the same or similar
	// statements.
	// Other assets making statements about the app will have to be updated
	// when a
	// key is rotated, however.
	//
	// (Note that the syntaxes for publishing and querying for statements
	// contain
	// syntactic sugar to easily let you specify apps that are known by
	// multiple
	// certificates.)

Asset: Uniquely identifies an asset.

A digital asset is an identifiable and addressable online entity that typically provides some service or content. Examples of assets are websites, Android apps, Twitter feeds, and Plus Pages.

func (*Asset) MarshalJSON 

func (s *Asset) MarshalJSON() ([]byte, error)

type AssetlinksCheckCall 

type AssetlinksCheckCall struct {
	// contains filtered or unexported fields
}

func (*AssetlinksCheckCall) Context 

func (c *AssetlinksCheckCall) Context(ctx context.Context) *AssetlinksCheckCall

Context sets the context to be used in this call's Do method. Any pending HTTP request will be aborted if the provided context is canceled.

func (*AssetlinksCheckCall) Do 

func (c *AssetlinksCheckCall) Do(opts ...googleapi.CallOption) (*CheckResponse, error)

Do executes the "digitalassetlinks.assetlinks.check" call. Exactly one of *CheckResponse or error will be non-nil. Any non-2xx status code is an error. Response headers are in either *CheckResponse.ServerResponse.Header or (if a response was returned at all) in error.(*googleapi.Error).Header. Use googleapi.IsNotModified to check whether the returned error was because http.StatusNotModified was returned.

func (*AssetlinksCheckCall) Fields 

func (c *AssetlinksCheckCall) Fields(s ...googleapi.Field) *AssetlinksCheckCall

Fields allows partial responses to be retrieved. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse for more information.

func (*AssetlinksCheckCall) Header 

func (c *AssetlinksCheckCall) Header() http.Header

Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.

func (*AssetlinksCheckCall) IfNoneMatch 

func (c *AssetlinksCheckCall) IfNoneMatch(entityTag string) *AssetlinksCheckCall

IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

func (*AssetlinksCheckCall) Relation 

func (c *AssetlinksCheckCall) Relation(relation string) *AssetlinksCheckCall

Relation sets the optional parameter "relation": Query string for the relation.

We identify relations with strings of the format `<kind>/<detail>`, where `<kind>` must be one of a set of pre-defined purpose categories, and `<detail>` is a free-form lowercase alphanumeric string that describes the specific use case of the statement.

Refer to [our API documentation](/digital-asset-links/v1/relation-strings) for the current list of supported relations.

For a query to match an asset link, both the query's and the asset link's relation strings must match exactly.

Example: A query with relation `delegate_permission/common.handle_all_urls` matches an asset link with relation `delegate_permission/common.handle_all_urls`.

func (*AssetlinksCheckCall) SourceAndroidAppCertificateSha256Fingerprint 

func (c *AssetlinksCheckCall) SourceAndroidAppCertificateSha256Fingerprint(sourceAndroidAppCertificateSha256Fingerprint string) *AssetlinksCheckCall

SourceAndroidAppCertificateSha256Fingerprint sets the optional parameter "source.androidApp.certificate.sha256Fingerprint": The uppercase SHA-265 fingerprint of the certificate. From the PEM 

certificate, it can be acquired like this:

   $ keytool -printcert -file $CERTFILE | grep SHA256:
   SHA256: 14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:

\
        42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

or like this: 

$ openssl x509 -in $CERTFILE -noout -fingerprint -sha256
SHA256

Fingerprint=14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64: \
        16:A0:83:42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

In this example, the contents of this field would be `14:6D:E9:83:C5:73: 06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:42:E6:1D:BE :A8:8A:04:96:B2:3F:CF: 44:E5`.

If these tools are not available to you, you can convert the PEM certificate into the DER format, compute the SHA-256 hash of that string and represent the result as a hexstring (that is, uppercase hexadecimal representations of each octet, separated by colons).

func (*AssetlinksCheckCall) SourceAndroidAppPackageName 

func (c *AssetlinksCheckCall) SourceAndroidAppPackageName(sourceAndroidAppPackageName string) *AssetlinksCheckCall

SourceAndroidAppPackageName sets the optional parameter "source.androidApp.packageName": Android App assets are naturally identified by their Java package name. For example, the Google Maps app uses the package name `com.google.android.apps.maps`. REQUIRED

func (*AssetlinksCheckCall) SourceWebSite 

func (c *AssetlinksCheckCall) SourceWebSite(sourceWebSite string) *AssetlinksCheckCall

SourceWebSite sets the optional parameter "source.web.site": Web assets are identified by a URL that contains only the scheme, hostname and port parts. The format is 

http[s]://<hostname>[:<port>]

Hostnames must be fully qualified: they must end in a single period (".").

Only the schemes "http" and "https" are currently allowed.

Port numbers are given as a decimal number, and they must be omitted if the standard port numbers are used: 80 for http and 443 for https.

We call this limited URL the "site". All URLs that share the same scheme, hostname and port are considered to be a part of the site and thus belong to the web asset.

Example: the asset with the site `https://www.google.com` contains all these URLs:

But it does not contain these URLs:

REQUIRED

func (*AssetlinksCheckCall) TargetAndroidAppCertificateSha256Fingerprint 

func (c *AssetlinksCheckCall) TargetAndroidAppCertificateSha256Fingerprint(targetAndroidAppCertificateSha256Fingerprint string) *AssetlinksCheckCall

TargetAndroidAppCertificateSha256Fingerprint sets the optional parameter "target.androidApp.certificate.sha256Fingerprint": The uppercase SHA-265 fingerprint of the certificate. From the PEM 

certificate, it can be acquired like this:

   $ keytool -printcert -file $CERTFILE | grep SHA256:
   SHA256: 14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:

\
        42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

or like this: 

$ openssl x509 -in $CERTFILE -noout -fingerprint -sha256
SHA256

Fingerprint=14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64: \
        16:A0:83:42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

In this example, the contents of this field would be `14:6D:E9:83:C5:73: 06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:42:E6:1D:BE :A8:8A:04:96:B2:3F:CF: 44:E5`.

If these tools are not available to you, you can convert the PEM certificate into the DER format, compute the SHA-256 hash of that string and represent the result as a hexstring (that is, uppercase hexadecimal representations of each octet, separated by colons).

func (*AssetlinksCheckCall) TargetAndroidAppPackageName 

func (c *AssetlinksCheckCall) TargetAndroidAppPackageName(targetAndroidAppPackageName string) *AssetlinksCheckCall

TargetAndroidAppPackageName sets the optional parameter "target.androidApp.packageName": Android App assets are naturally identified by their Java package name. For example, the Google Maps app uses the package name `com.google.android.apps.maps`. REQUIRED

func (*AssetlinksCheckCall) TargetWebSite 

func (c *AssetlinksCheckCall) TargetWebSite(targetWebSite string) *AssetlinksCheckCall

TargetWebSite sets the optional parameter "target.web.site": Web assets are identified by a URL that contains only the scheme, hostname and port parts. The format is 

http[s]://<hostname>[:<port>]

Hostnames must be fully qualified: they must end in a single period (".").

Only the schemes "http" and "https" are currently allowed.

Port numbers are given as a decimal number, and they must be omitted if the standard port numbers are used: 80 for http and 443 for https.

We call this limited URL the "site". All URLs that share the same scheme, hostname and port are considered to be a part of the site and thus belong to the web asset.

type AssetlinksService 

type AssetlinksService struct {
	// contains filtered or unexported fields
}

func NewAssetlinksService 

func NewAssetlinksService(s *Service) *AssetlinksService

func (*AssetlinksService) Check 

func (r *AssetlinksService) Check() *AssetlinksCheckCall

Check: Determines whether the specified (directional) relationship exists between the specified source and target assets.

The relation describes the intent of the link between the two assets as claimed by the source asset. An example for such relationships is the delegation of privileges or permissions.

This command is most often used by infrastructure systems to check preconditions for an action. For example, a client may want to know if it is OK to send a web URL to a particular mobile app instead. The client can check for the relevant asset link from the website to the mobile app to decide if the operation should be allowed.

A note about security: if you specify a secure asset as the source, such as an HTTPS website or an Android app, the API will ensure that any statements used to generate the response have been made in a secure way by the owner of that asset. Conversely, if the source asset is an insecure HTTP website (that is, the URL starts with `http://` instead of `https://`), the API cannot verify its statements securely, and it is not possible to ensure that the website's statements have not been altered by a third party. For more information, see the [Digital Asset Links technical design specification](https://github.com/google/digitalasset links/blob/master/well-known/details.md).

func (c *StatementsListCall) Context(ctx context.Context) *StatementsListCall

Context sets the context to be used in this call's Do method. Any pending HTTP request will be aborted if the provided context is canceled.

func (*StatementsListCall) Do 

func (c *StatementsListCall) Do(opts ...googleapi.CallOption) (*ListResponse, error)

Do executes the "digitalassetlinks.statements.list" call. Exactly one of *ListResponse or error will be non-nil. Any non-2xx status code is an error. Response headers are in either *ListResponse.ServerResponse.Header or (if a response was returned at all) in error.(*googleapi.Error).Header. Use googleapi.IsNotModified to check whether the returned error was because http.StatusNotModified was returned.

func (*StatementsListCall) Fields 

func (c *StatementsListCall) Fields(s ...googleapi.Field) *StatementsListCall

Fields allows partial responses to be retrieved. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse for more information.

func (*StatementsListCall) Header 

func (c *StatementsListCall) Header() http.Header

Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.

func (*StatementsListCall) IfNoneMatch 

func (c *StatementsListCall) IfNoneMatch(entityTag string) *StatementsListCall

IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

func (*StatementsListCall) Relation 

func (c *StatementsListCall) Relation(relation string) *StatementsListCall

Relation sets the optional parameter "relation": Use only associations that match the specified relation.

See the [`Statement`](#Statement) message for a detailed definition of relation strings.

For a query to match a statement, one of the following must be true:

* both the query's and the statement's relation strings match exactly, 

or

* the query's relation string is empty or missing.

Example: A query with relation `delegate_permission/common.handle_all_urls` matches an asset link with relation `delegate_permission/common.handle_all_urls`.

func (*StatementsListCall) SourceAndroidAppCertificateSha256Fingerprint 

func (c *StatementsListCall) SourceAndroidAppCertificateSha256Fingerprint(sourceAndroidAppCertificateSha256Fingerprint string) *StatementsListCall

SourceAndroidAppCertificateSha256Fingerprint sets the optional parameter "source.androidApp.certificate.sha256Fingerprint": The uppercase SHA-265 fingerprint of the certificate. From the PEM 

certificate, it can be acquired like this:

   $ keytool -printcert -file $CERTFILE | grep SHA256:
   SHA256: 14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:

\
        42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

or like this: 

$ openssl x509 -in $CERTFILE -noout -fingerprint -sha256
SHA256

Fingerprint=14:6D:E9:83:C5:73:06:50:D8:EE:B9:95:2F:34:FC:64: \
        16:A0:83:42:E6:1D:BE:A8:8A:04:96:B2:3F:CF:44:E5

In this example, the contents of this field would be `14:6D:E9:83:C5:73: 06:50:D8:EE:B9:95:2F:34:FC:64:16:A0:83:42:E6:1D:BE :A8:8A:04:96:B2:3F:CF: 44:E5`.

If these tools are not available to you, you can convert the PEM certificate into the DER format, compute the SHA-256 hash of that string and represent the result as a hexstring (that is, uppercase hexadecimal representations of each octet, separated by colons).

func (*StatementsListCall) SourceAndroidAppPackageName 

func (c *StatementsListCall) SourceAndroidAppPackageName(sourceAndroidAppPackageName string) *StatementsListCall

SourceAndroidAppPackageName sets the optional parameter "source.androidApp.packageName": Android App assets are naturally identified by their Java package name. For example, the Google Maps app uses the package name `com.google.android.apps.maps`. REQUIRED

func (*StatementsListCall) SourceWebSite 

func (c *StatementsListCall) SourceWebSite(sourceWebSite string) *StatementsListCall

SourceWebSite sets the optional parameter "source.web.site": Web assets are identified by a URL that contains only the scheme, hostname and port parts. The format is 

http[s]://<hostname>[:<port>]

Hostnames must be fully qualified: they must end in a single period (".").

Only the schemes "http" and "https" are currently allowed.

Port numbers are given as a decimal number, and they must be omitted if the standard port numbers are used: 80 for http and 443 for https.

We call this limited URL the "site". All URLs that share the same scheme, hostname and port are considered to be a part of the site and thus belong to the web asset.

Example: the asset with the site `https://www.google.com` contains all these URLs:

But it does not contain these URLs:

type StatementsService 

type StatementsService struct {
	// contains filtered or unexported fields
}

func NewStatementsService 

func NewStatementsService(s *Service) *StatementsService

func (*StatementsService) List 

func (r *StatementsService) List() *StatementsListCall

List: Retrieves a list of all statements from a given source that match the specified target and statement string.

The API guarantees that all statements with secure source assets, such as HTTPS websites or Android apps, have been made in a secure way by the owner of those assets, as described in the [Digital Asset Links technical design specification](https://github.com/google/digitalassetlinks/blob /master/well-known/details.md). Specifically, you should consider that for insecure websites (that is, where the URL starts with `http://` instead of `https://`), this guarantee cannot be made.

The `List` command is most useful in cases where the API client wants to know all the ways in which two assets are related, or enumerate all the relationships from a particular source asset. Example: a feature that helps users navigate to related items. When a mobile app is running on a device, the feature would make it easy to navigate to the corresponding web site or Google+ profile.
