Package cloud.google.com/go/iam/credentials/apiv1 (v0.96.0)

Package credentials is an auto-generated package for the IAM Service Account Credentials API.

Creates short-lived, limited-privilege credentials for IAM service accounts.

Example usage

To get started with this package, create a client.

ctx := context.Background()
c, err := credentials.NewIamCredentialsClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
c, err := credentials.NewIamCredentialsClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &credentialspb.GenerateAccessTokenRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/google.golang.org/genproto/googleapis/iam/credentials/v1#GenerateAccessTokenRequest.
}
resp, err := c.GenerateAccessToken(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

IamCredentialsCallOptions

type IamCredentialsCallOptions struct {
	GenerateAccessToken []gax.CallOption
	GenerateIdToken     []gax.CallOption
	SignBlob            []gax.CallOption
	SignJwt             []gax.CallOption
}

IamCredentialsCallOptions contains the retry settings for each method of IamCredentialsClient.

IamCredentialsClient

type IamCredentialsClient struct {

	// The call options for this service.
	CallOptions *IamCredentialsCallOptions
	// contains filtered or unexported fields
}

IamCredentialsClient is a client for interacting with IAM Service Account Credentials API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

A service account is a special type of Google account that belongs to your application or a virtual machine (VM), instead of to an individual end user. Your application assumes the identity of the service account to call Google APIs, so that the users aren’t directly involved.

Service account credentials are used to temporarily assume the identity of the service account. Supported credential types include OAuth 2.0 access tokens, OpenID Connect ID tokens, self-signed JSON Web Tokens (JWTs), and more.

func NewIamCredentialsClient

func NewIamCredentialsClient(ctx context.Context, opts ...option.ClientOption) (*IamCredentialsClient, error)

NewIamCredentialsClient creates a new iam credentials client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Example

package main

import (
	credentials "cloud.google.com/go/iam/credentials/apiv1"
	"context"
)

func main() {
	ctx := context.Background()
	c, err := credentials.NewIamCredentialsClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (*IamCredentialsClient) Close

func (c *IamCredentialsClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*IamCredentialsClient) Connection

func (c *IamCredentialsClient) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated.

func (*IamCredentialsClient) GenerateAccessToken

GenerateAccessToken generates an OAuth 2.0 access token for a service account.

Example

package main

import (
	credentials "cloud.google.com/go/iam/credentials/apiv1"
	"context"
	credentialspb "google.golang.org/genproto/googleapis/iam/credentials/v1"
)

func main() {
	ctx := context.Background()
	c, err := credentials.NewIamCredentialsClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &credentialspb.GenerateAccessTokenRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/iam/credentials/v1#GenerateAccessTokenRequest.
	}
	resp, err := c.GenerateAccessToken(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

func (*IamCredentialsClient) GenerateIdToken

GenerateIdToken generates an OpenID Connect ID token for a service account.

Example

package main

import (
	credentials "cloud.google.com/go/iam/credentials/apiv1"

		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/iam/credentials/v1#GenerateIdTokenRequest.
	}

		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
