// 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.
|
|
//
