Methods

build(Channel channel, CallOptions callOptions)

protected CloudFunctionsServiceGrpc.CloudFunctionsServiceFutureStub build(Channel channel, CallOptions callOptions)
Parameters
Name Description
channel io.grpc.Channel
callOptions io.grpc.CallOptions
Returns
Type Description
CloudFunctionsServiceGrpc.CloudFunctionsServiceFutureStub
Overrides
io.grpc.stub.AbstractStub.build(io.grpc.Channel,io.grpc.CallOptions)

callFunction(CallFunctionRequest request)

public ListenableFuture<CallFunctionResponse> callFunction(CallFunctionRequest request)

Synchronously invokes a deployed Cloud Function. To be used for testing purposes as very limited traffic is allowed. For more information on the actual limits, refer to Rate Limits.

Parameter
Name Description
request CallFunctionRequest
Returns
Type Description
com.google.common.util.concurrent.ListenableFuture<CallFunctionResponse>

createFunction(CreateFunctionRequest request)

public ListenableFuture<Operation> createFunction(CreateFunctionRequest request)

Creates a new function. If a function with the given name already exists in the specified project, the long running operation will return ALREADY_EXISTS error.

Parameter
Name Description
request CreateFunctionRequest
Returns
Type Description
com.google.common.util.concurrent.ListenableFuture<Operation>

deleteFunction(DeleteFunctionRequest request)

public ListenableFuture<Operation> deleteFunction(DeleteFunctionRequest request)

Deletes a function with the given name from the specified project. If the given function is used by some trigger, the trigger will be updated to remove this function.

Parameter
Name Description
request DeleteFunctionRequest
Returns
Type Description
com.google.common.util.concurrent.ListenableFuture<Operation>

generateDownloadUrl(GenerateDownloadUrlRequest request)

public ListenableFuture<GenerateDownloadUrlResponse> generateDownloadUrl(GenerateDownloadUrlRequest request)

Returns a signed URL for downloading deployed function source code. The URL is only valid for a limited period and should be used within minutes after generation. For more information about the signed URL usage see: https://cloud.google.com/storage/docs/access-control/signed-urls

Parameter
Name Description
request GenerateDownloadUrlRequest
Returns
Type Description
com.google.common.util.concurrent.ListenableFuture<GenerateDownloadUrlResponse>

generateUploadUrl(GenerateUploadUrlRequest request)

public ListenableFuture<GenerateUploadUrlResponse> generateUploadUrl(GenerateUploadUrlRequest request)

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. 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
Parameter
Name Description
request GenerateUploadUrlRequest
Returns
Type Description
com.google.common.util.concurrent.ListenableFuture<GenerateUploadUrlResponse>
