Documentation ¶
Overview ¶
Package sts provides access to the Security Token Service API.
For product documentation, see: http://cloud.google.com/iam/docs/workload-identity-federation
Creating a client ¶
Usage example:
import "google.golang.org/api/sts/v1beta" ... ctx := context.Background() stsService, err := sts.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:
stsService, err := sts.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, ...) stsService, err := sts.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
See https://godoc.org/google.golang.org/api/option/ for details on options.

type GoogleIdentityStsV1betaExchangeTokenRequest ¶
type GoogleIdentityStsV1betaExchangeTokenRequest struct { // Audience: The full resource name of the identity provider; for // example: // `https://iam.googleapis.com/projects/{PROJECT_ID}/workloadIdentityPool // s/{POOL_ID}/providers/{PROVIDER_ID}`. Required when exchanging an // external credential for a Google access token. Audience string `json:"audience,omitempty"` // GrantType: Required. The grant type. Must be // `urn:ietf:params:oauth:grant-type:token-exchange`, which indicates a // token exchange is requested. GrantType string `json:"grantType,omitempty"` // Options: A set of features that Security Token Service supports, in // addition to the standard OAuth 2.0 token exchange, formatted as a // serialized JSON object of Options. Options string `json:"options,omitempty"` // RequestedTokenType: Required. An identifier for the type of requested // security token. Must be // `urn:ietf:params:oauth:token-type:access_token`. RequestedTokenType string `json:"requestedTokenType,omitempty"` // Scope: The OAuth 2.0 scopes to include on the resulting access token, // formatted as a list of space-delimited, case-sensitive strings. // Required when exchanging an external credential for a Google access // token. Scope string `json:"scope,omitempty"` // SubjectToken: Required. The input token. This is a either an external // credential issued by a WorkloadIdentityPoolProvider, or a short-lived // access token issued by Google. If the token is an OIDC JWT, it must // use the JWT format defined in [RFC // 7523](https://tools.ietf.org/html/rfc7523), and `subject_token_type` // must be `urn:ietf:params:oauth:token-type:jwt`. The following headers // are required: - **`kid`**: The identifier of the signing key securing // the JWT. - **`alg`**: The cryptographic algorithm securing the JWT. // Must be `RS256`. The following payload fields are required. For more // information, see [RFC 7523, Section // 3](https://tools.ietf.org/html/rfc7523#section-3). - **`iss`**: The // issuer of the token. The issuer must provide a discovery document at // `/.well-known/openid-configuration`, formatted according to section // 4.2 of the [OIDC 1.0 Discovery // specification](https://openid.net/specs/openid-connect-discovery-1_0.h // tml#ProviderConfigurationResponse). - **`iat`**: The issue time, in // seconds, since epoch. Must be in the past. - **`exp`**: The // expiration time, in seconds, since epoch. Must be fewer than 48 hours // after `iat`. Shorter expiration times are more. secure. If possible, // we recommend setting an expiration time fewer than 6 hours. - // **`sub`**: The identity asserted in the JWT. - **`aud`**: Configured // by the mapper policy. The default value is the service account's // unique ID. Example header: “` { "alg": "RS256", "kid": "us-east-11" // } “` Example payload: “` { "iss": "https://accounts.google.com", // "iat": 1517963104, "exp": 1517966704, "aud": "113475438248934895348", // "sub": "113475438248934895348", "my_claims": { "additional_claim": // "value" } } “` If `subject_token` is an AWS token, it must be a // serialized, // [signed](https://docs.aws.amazon.com/general/latest/gr/signing_aws_api // _requests.html) request to the AWS // [`GetCallerIdentity()`](https://docs.aws.amazon.com/STS/latest/APIRefe // rence/API_GetCallerIdentity) method. Format the request as // URL-encoded JSON, and set the `subject_token_type` parameter to // `urn:ietf:params:aws:token-type:aws4_request`. The following // parameters are required: - **`url`**: The URL of the AWS STS endpoint // for `GetCallerIdentity()`, such as // `https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15 // `. Regional endpoints are also supported. - **`method`:** The HTTP // request method: `POST`. - **`headers`**: The HTTP request headers, // which must include: - **`Authorization`**: The request signature. - // **`x-amz-date`**`: The time you will send the request, formatted as // an [ISO8601 // Basic](https://docs.aws.amazon.com/general/latest/gr/sigv4_elements.ht // ml#sigv4_elements_date) string. This is typically set to the current // time, and used to prevent replay attacks. - **`host`**: The hostname // of the `url` field; for example, `sts.amazonaws.com`. - // **`x-goog-cloud-target-resource`**: The full, canonical resource name // of the WorkloadIdentityPoolProvider, with or without the HTTPS // prefix. For example: “` // //iam.googleapis.com/projects//locations//workloadIdentityPools//provi // ders/ // https://iam.googleapis.com/projects//locations//workloadIdentityPools//providers/ “` Signing this header as part of the signature is recommended to ensure data integrity. If you are using temporary security credentials provided by AWS, you must also include the header `x-amz-security-token`, with the value `[SESSION_TOKEN]`. The following is an example of a signed, serialized request: “` { "headers":[ {"key": "x-amz-date", "value": "20200815T015049Z"}, {"key": "Authorization", "value": "AWS4-HMAC-SHA256+Credential=$credential,+SignedHeaders=host;x-amz-date;x-goog-cloud-target-resource,+Signature=$signature"}, {"key": "x-goog-cloud-target-resource", "value": "//iam.googleapis.com/projects//locations//workloadIdentityPools//providers/"}, {"key": "host", "value": "sts.amazonaws.com"} . ], "method":"POST", "url":"https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15" } “` You can also use a Google-issued OAuth 2.0 access token with this field to obtain an access token with new security attributes applied, such as an AccessBoundary. In this case, set `subject_token_type` to `urn:ietf:params:oauth:token-type:access_token`. Applying additional security attributes on access tokens that already contain security attributes is not // allowed. SubjectToken string `json:"subjectToken,omitempty"` // SubjectTokenType: Required. An identifier that indicates the type of // the security token in the `subject_token` parameter. Supported values // are `urn:ietf:params:oauth:token-type:jwt`, // `urn:ietf:params:aws:token-type:aws4_request` and // `urn:ietf:params:oauth:token-type:access_token`. SubjectTokenType string `json:"subjectTokenType,omitempty"` // ForceSendFields is a list of field names (e.g. "Audience") to // unconditionally include in API requests. By default, fields with // empty values are omitted from API requests. However, any non-pointer, // non-interface field appearing in ForceSendFields will be sent to the // server regardless of whether the field is empty or not. This may be // used to include empty fields in Patch requests. ForceSendFields []string `json:"-"` // NullFields is a list of field names (e.g. "Audience") to include in // API requests with the JSON null value. By default, fields with empty // values are omitted from API requests. However, any field with an // empty value appearing in NullFields will be sent to the server as // null. It is an error if a field in this list has a non-empty value. // This may be used to include null fields in Patch requests. NullFields []string `json:"-"` }
