Package functions is an auto-generated package for the Cloud Functions API.
Manages lightweight user-provided functions executed in response to events.
General documentation
For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:
- Authentication and Authorization
- Timeouts and Cancellation
- Testing against Client Libraries
- Debugging Client Libraries
- Inspecting errors
Example usage
To get started with this package, create a client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := functions.NewCloudFunctionsClient(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() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := functions.NewCloudFunctionsClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close() req := &functionspb.CallFunctionRequest{ // TODO: Fill request struct fields. // See https://pkg.go.dev/cloud.google.com/go/functions/apiv1/functionspb#CallFunctionRequest. } resp, err := c.CallFunction(ctx, req) if err != nil { // TODO: Handle error. } // TODO: Use resp. _ = resp
Use of Context
The ctx passed to NewCloudFunctionsClient 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() []stringDefaultAuthScopes reports the default set of authentication scopes to use with this package.
CloudFunctionIterator
type CloudFunctionIterator struct {
// Response is the raw response for the current page.
// It must be cast to the RPC response type.
// Calling Next() or InternalFetch() updates this value.
Response interface{}
// InternalFetch is for use by the Google Cloud Libraries only.
// It is not part of the stable interface of this package.
//
// InternalFetch returns results from a single call to the underlying RPC.
// The number of results is no greater than pageSize.
// If there are no more results, nextPageToken is empty and err is nil.
InternalFetch func(pageSize int, pageToken string) (results []*functionspb.CloudFunction, nextPageToken string, err error)
// contains filtered or unexported fields
}CloudFunctionIterator manages a stream of *functionspb.CloudFunction.
func (*CloudFunctionIterator) All
func (it *CloudFunctionIterator) All() iter.Seq2[*functionspb.CloudFunction, error]All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.
func (*CloudFunctionIterator) Next
func (it *CloudFunctionIterator) Next() (*functionspb.CloudFunction, error)Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.
func (*CloudFunctionIterator) PageInfo
func (it *CloudFunctionIterator) PageInfo() *iterator.PageInfoPageInfo supports pagination. See the google.golang.org/api/iterator package for details.
CloudFunctionsCallOptions
type CloudFunctionsCallOptions struct {

ListOperations []gax.CallOption
}CloudFunctionsCallOptions contains the retry settings for each method of CloudFunctionsClient.
CloudFunctionsClient
type CloudFunctionsClient struct {
// The call options for this service.
CallOptions *CloudFunctionsCallOptions
// LROClient is used internally to handle long-running operations.
// It is exposed so that its CallOptions can be modified if required.
// Users should not Close this client.
LROClient *lroauto.OperationsClient
// contains filtered or unexported fields
}CloudFunctionsClient is a client for interacting with Cloud Functions API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
A service that application uses to manipulate triggers and functions.
func NewCloudFunctionsClient
func NewCloudFunctionsClient(ctx context.Context, opts ...option.ClientOption) (*CloudFunctionsClient, error)NewCloudFunctionsClient creates a new cloud functions service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.
A service that application uses to manipulate triggers and functions.

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

func (c *CloudFunctionsClient) GenerateUploadUrl(ctx context.Context, req *functionspb.GenerateUploadUrlRequest, opts ...gax.CallOption) (*functionspb.GenerateUploadUrlResponse, error)GenerateUploadUrl returns a signed URL for uploading a function source code. For more information about the signed URL usage see: https://cloud.google.com/storage/docs/access-control/signed-urls (at https://cloud.google.com/storage/docs/access-control/signed-urls). Once the function source code upload is complete, the used signed URL should be provided in CreateFunction or UpdateFunction request as a reference to the function source code.
When uploading source code to the generated signed URL, please follow these restrictions:
Source file type should be a zip file.
Source file size should not exceed 100MB limit.
No credentials should be attached - the signed URLs provide access to the
target bucket using internal service identity; if credentials were
attached, the identity from the credentials would be used, but that
identity does not have permissions to upload files to the URL.
When making a HTTP PUT request, these two headers need to be specified:
content-type: application/zip
x-goog-content-length-range: 0,104857600
And this header SHOULD NOT be specified:
Authorization: Bearer YOUR_TOKEN

func (*CloudFunctionsClient) UpdateFunctionOperation
func (c *CloudFunctionsClient) UpdateFunctionOperation(name string) *UpdateFunctionOperationUpdateFunctionOperation returns a new UpdateFunctionOperation from a given name. The name must be that of a previously created UpdateFunctionOperation, possibly from a different process.

func (*CreateFunctionOperation) Metadata
func (op *CreateFunctionOperation) Metadata() (*functionspb.OperationMetadataV1, error)Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.
func (*CreateFunctionOperation) Name
func (op *CreateFunctionOperation) Name() stringName returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

Poll also fetches the latest metadata, which can be retrieved by Metadata.
If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.
func (*CreateFunctionOperation) Wait
func (op *CreateFunctionOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*functionspb.CloudFunction, error)Wait blocks until the long-running operation is completed, returning the response and any errors encountered.
See documentation of Poll for error-handling information.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.
func (*DeleteFunctionOperation) Wait
