Google Cloud Functions V1 Client - Class CloudFunctionsServiceClient (1.0.3)

Reference documentation and code samples for the Google Cloud Functions V1 Client class CloudFunctionsServiceClient.

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:

$cloudFunctionsServiceClient = new CloudFunctionsServiceClient();
try {
    $formattedName = $cloudFunctionsServiceClient->cloudFunctionName('[PROJECT]', '[LOCATION]', '[FUNCTION]');
    $data = 'data';
    $response = $cloudFunctionsServiceClient->callFunction($formattedName, $data);
} finally {
    $cloudFunctionsServiceClient->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.

Methods

cloudFunctionName

Formats a string containing the fully-qualified path to represent a cloud_function resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`
`function`	`string`

Returns
Type	Description
`string`	The formatted cloud_function resource.

cryptoKeyName

Formats a string containing the fully-qualified path to represent a crypto_key resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`
`keyRing`	`string`
`cryptoKey`	`string`

Returns
Type	Description
`string`	The formatted crypto_key resource.

locationName

Formats a string containing the fully-qualified path to represent a location resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`

Returns
Type	Description
`string`	The formatted location resource.

repositoryName

Formats a string containing the fully-qualified path to represent a repository resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`
`repository`	`string`

Returns
Type	Description
`string`	The formatted repository resource.

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

cloudFunction: projects/{project}/locations/{location}/functions/{function}
cryptoKey: projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}
location: projects/{project}/locations/{location}
repository: projects/{project}/locations/{location}/repositories/{repository}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

resumeOperation

Resume an existing long running operation that was previously started by a long running API method. If $methodName is not provided, or does not match a long running API method, then the operation can still be resumed, but the OperationResponse object will not deserialize the final response.

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.

generateDownloadUrl

Parameters
Name	Description
`optionalArgs`	`array` Optional.

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

Parameters
Name	Description
`optionalArgs`	`array` Optional.
`↳ parent`	`string` The project and location in which the Google Cloud Storage signed URL should be generated, specified in the format `projects//locations/`.
`↳ kmsKeyName`	`string` Resource name of a KMS crypto key (managed by the user) used to encrypt/decrypt function source code objects in staging Cloud Storage buckets. When you generate an upload url and upload your source code, it gets copied to a staging Cloud Storage bucket in an internal regional project. 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). GCF will delegate access to the Google Storage service account in the internal project.
`↳ 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.
