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

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

Service Description: A session represents an interaction with a user. You retrieve user input and pass it to the DetectIntent method to determine user intent and respond.

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:

$sessionsClient = new SessionsClient();
try {
    $formattedSession = $sessionsClient->sessionName('[PROJECT]', '[LOCATION]', '[AGENT]', '[SESSION]');
    $queryInput = new QueryInput();
    $response = $sessionsClient->detectIntent($formattedSession, $queryInput);
} finally {
    $sessionsClient->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.

detectIntent

Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause session entity types to be updated, which in turn might affect results of future queries.

Note: Always use agent versions for production traffic. See Versions and environments.

Parameters
Name	Description
`session`	`string` Required. The name of the session this query is sent to. Format: `projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/sessions/<Session ID>` or `projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/environments/<Environment ID>/sessions/<Session ID>`. If `Environment ID` is not specified, we assume default 'draft' environment. It's up to the API caller to choose an appropriate `Session ID`. It can be a random number or some type of session identifiers (preferably hashed). The length of the `Session ID` must not exceed 36 characters. For more information, see the sessions guide. Note: Always use agent versions for production traffic. See Versions and environments.
`queryInput`	`Google\Cloud\Dialogflow\Cx\V3\QueryInput` Required. The input specification.
`optionalArgs`	`array` Optional.
`↳ queryParams`	`QueryParameters` The parameters of this query.
`↳ outputAudioConfig`	`OutputAudioConfig` Instructs the speech synthesizer how to generate the output audio.
`↳ 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.
