Google Cloud Dialogflow Cx V3 Client - Class PagesClient (0.1.1)

Reference documentation and code samples for the Google Cloud Dialogflow Cx V3 Client class PagesClient.

Service Description: Service for managing Pages .

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:

 $pagesClient = new PagesClient();
try {
    $formattedParent = $pagesClient->flowName('[PROJECT]', '[LOCATION]', '[AGENT]', '[FLOW]');
    $page = new Page();
    $response = $pagesClient->createPage($formattedParent, $page);
} finally {
    $pagesClient->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.

Namespace

Google \ Cloud \ Dialogflow \ Cx \ V3

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.
