Class CloudFunctionsServiceClient

java.lang.Object
com.google.cloud.functions.v1.CloudFunctionsServiceClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class CloudFunctionsServiceClient extends Object implements BackgroundResource
Service Description: A service that application uses to manipulate triggers and functions.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started: 


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (CloudFunctionsServiceClient cloudFunctionsServiceClient =
     CloudFunctionsServiceClient.create()) {
   CloudFunctionName name = CloudFunctionName.of("[PROJECT]", "[LOCATION]", "[FUNCTION]");
   CloudFunction response = cloudFunctionsServiceClient.getFunction(name);
 }

Note: close() needs to be called on the CloudFunctionsServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods

ListFunctions

Returns a list of functions that belong to the requested project.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listFunctions(ListFunctionsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listFunctionsPagedCallable()

GetFunction

Returns a function with the given name from the requested project.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getFunction(GetFunctionRequest request)

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. 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`

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of CloudFunctionsServiceSettings to create(). For example:

To customize credentials: 


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudFunctionsServiceSettings cloudFunctionsServiceSettings =
     CloudFunctionsServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 CloudFunctionsServiceClient cloudFunctionsServiceClient =
     CloudFunctionsServiceClient.create(cloudFunctionsServiceSettings);

To customize the endpoint: 


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudFunctionsServiceSettings cloudFunctionsServiceSettings =
     CloudFunctionsServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 CloudFunctionsServiceClient cloudFunctionsServiceClient =
     CloudFunctionsServiceClient.create(cloudFunctionsServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire: 


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 CloudFunctionsServiceSettings cloudFunctionsServiceSettings =
     CloudFunctionsServiceSettings.newHttpJsonBuilder().build();
 CloudFunctionsServiceClient cloudFunctionsServiceClient =
     CloudFunctionsServiceClient.create(cloudFunctionsServiceSettings);

    • 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. 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`
