Cloud PubSub V1 Client - Class SubscriberClient (2.8.2)

Reference documentation and code samples for the Cloud PubSub V1 Client class SubscriberClient.

Service Description: The service that an application uses to manipulate subscriptions and to consume messages from a subscription via the Pull method or by establishing a bi-directional stream using the StreamingPull method.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods.

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.

Namespace

Google \ Cloud \ PubSub \ V1 \ Client

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.
↳ logger false|LoggerInterface

A PSR-3 compliant logger. If set to false, logging is disabled, ignoring the 'GOOGLE_SDK_PHP_LOGGING' environment flag

acknowledge

Acknowledges the messages associated with the ack_ids in the AcknowledgeRequest. The Pub/Sub system can remove the relevant messages from the subscription.

Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.

The async variant is SubscriberClient::acknowledgeAsync() .

Parameters
Name Description
request Google\Cloud\PubSub\V1\AcknowledgeRequest

A request to house fields associated with the call.
callOptions 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.

use Google\ApiCore\ApiException;
use Google\Cloud\PubSub\V1\AcknowledgeRequest;
use Google\Cloud\PubSub\V1\Client\SubscriberClient;

/**

createSnapshot

Creates a snapshot from the requested subscription. Snapshots are used in Seek operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot.

If the snapshot already exists, returns ALREADY_EXISTS. If the requested subscription doesn't exist, returns NOT_FOUND. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then FAILED_PRECONDITION is returned. See also the Snapshot.expire_time field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the resource name format. The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.

The async variant is SubscriberClient::createSnapshotAsync() .

modifyAckDeadline

Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level ackDeadlineSeconds used for subsequent messages.

The async variant is SubscriberClient::modifyAckDeadlineAsync() .

Parameters
Name Description
request Google\Cloud\PubSub\V1\ModifyAckDeadlineRequest

A request to house fields associated with the call.
callOptions 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.
Example 
use Google\ApiCore\ApiException;
use Google\Cloud\PubSub\V1\Client\SubscriberClient;

 *                                      {@see SubscriberClient::subscriptionName()} for help formatting this field.
 * @param string $ackIdsElement         List of acknowledgment IDs.
 * @param int    $ackDeadlineSeconds    The new ack deadline with respect to the time this request was
 *                                      sent to the Pub/Sub system. For example, if the value is 10, the new ack
 *                                      deadline will expire 10 seconds after the `ModifyAckDeadline` call was
 *                                      made. Specifying zero might immediately make the message available for
 *                                      delivery to another subscriber client. This typically results in an
 *                                      increase in the rate of message redeliveries (that is, duplicates).
 *                                      The minimum deadline you can specify is 0 seconds.
 *                                      The maximum deadline you can specify in a single request is 600 seconds

streamingPull

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status UNAVAILABLE to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

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.

The async variant is SubscriberClient::testIamPermissionsAsync() .
