Class FunctionServiceClient

java.lang.Object
com.google.cloud.functions.v2alpha.FunctionServiceClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@BetaApi @Generated("by gapic-generator-java") public class FunctionServiceClient extends Object implements BackgroundResource
Service Description: Google Cloud Functions is used to deploy functions that are executed by Google in response to various events. Data connected with that event is passed to a function as the input data.

A **function** is a resource which describes a function that should be executed and how it is triggered.

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 (FunctionServiceClient functionServiceClient = FunctionServiceClient.create()) {
   FunctionName name = FunctionName.of("[PROJECT]", "[LOCATION]", "[FUNCTION]");
   Function response = functionServiceClient.getFunction(name);
 }

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

Methods
Method Description Method Variants

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)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getFunction(FunctionName name)

  • getFunction(String name)

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

  • getFunctionCallable()

ListFunctions

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

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.
  • 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, specify this header:

  • `content-type: application/zip`

Do not specify this header:

  • `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 FunctionServiceSettings 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
 FunctionServiceSettings functionServiceSettings =
     FunctionServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 FunctionServiceClient functionServiceClient =
     FunctionServiceClient.create(functionServiceSettings);

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
 FunctionServiceSettings functionServiceSettings =
     FunctionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 FunctionServiceClient functionServiceClient =
     FunctionServiceClient.create(functionServiceSettings);

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
 FunctionServiceSettings functionServiceSettings =
     FunctionServiceSettings.newHttpJsonBuilder().build();
 FunctionServiceClient functionServiceClient =
     FunctionServiceClient.create(functionServiceSettings);

    • setIamPolicyCallable

      public final UnaryCallable<SetIamPolicyRequest,Policy> setIamPolicyCallable()
      Sets the access control policy on the specified resource. Replacesany existing policy.

      Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED`errors.

      Sample code: 

      
 // 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 (FunctionServiceClient functionServiceClient = FunctionServiceClient.create()) {

           .setUpdateMask(FieldMask.newBuilder().build())
           .build();
   ApiFuture<Policy> future = functionServiceClient.setIamPolicyCallable().futureCall(request);
   // Do something.
   Policy response = future.get();
 }

    • getIamPolicy

      public final Policy getIamPolicy(GetIamPolicyRequest request)
      Gets the access control policy for a resource. Returns an empty policyif the resource exists and does not have a policy set.

    • testIamPermissions

      public final TestIamPermissionsResponse testIamPermissions(TestIamPermissionsRequest request)
      Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a `NOT_FOUND` error.

      Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.
