Google Cloud Functions V2 Client - Class FunctionServiceClient (1.3.1)

Reference documentation and code samples for the Google Cloud Functions V2 Client class FunctionServiceClient.

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:

$functionServiceClient = new FunctionServiceClient();
try {
    $formattedParent = $functionServiceClient->locationName('[PROJECT]', '[LOCATION]');
    $function = new PBFunction();
    $operationResponse = $functionServiceClient->createFunction($formattedParent, $function);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $functionServiceClient->createFunction($formattedParent, $function);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $functionServiceClient->resumeOperation($operationName, 'createFunction');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $functionServiceClient->close();
}

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 parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

This service has a new (beta) implementation. See Google\Cloud\Functions\V2\Client\FunctionServiceClient to use the new surface.

Namespace

Google \ Cloud \ Functions \ V2

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

`↳ functionId`	`string` The ID to use for the function, which will become the final component of the function's resource name. This value should be 4-63 characters, and valid characters are /[a-z][0-9]-/.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

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, these two headers need to be specified:

content-type: application/zip

And this header SHOULD NOT be specified:

Authorization: Bearer YOUR_TOKEN

Parameters
Name	Description
`parent`	`string` Required. The project and location in which the Google Cloud Storage signed URL should be generated, specified in the format `projects//locations/`.
`optionalArgs`	`array` Optional.
`↳ kmsKeyName`	`string` [Preview] Resource name of a KMS crypto key (managed by the user) used to encrypt/decrypt function source code objects in intermediate Cloud Storage buckets. When you generate an upload url and upload your source code, it gets copied to an intermediate Cloud Storage bucket. The source code is then copied to a versioned directory in the sources bucket in the consumer project during the function deployment. It must match the pattern `projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}`. The Google Cloud Functions service account (service-{project_number}@gcf-admin-robot.iam.gserviceaccount.com) must be granted the role 'Cloud KMS CryptoKey Encrypter/Decrypter (roles/cloudkms.cryptoKeyEncrypterDecrypter)' on the Key/KeyRing/Project/Organization (least access preferred).

`optionalArgs`	`array` Optional.
`↳ options`	`GetPolicyOptions` OPTIONAL: A `GetPolicyOptions` object for specifying options to `GetIamPolicy`.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\Iam\V1\Policy`

testIamPermissions

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

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

Parameters
Name	Description
`resource`	`string` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.
`permissions`	`string[]` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\Iam\V1\TestIamPermissionsResponse`
