Google Cloud Dialogflow V2 Client - Class ParticipantsClient (1.10.2)

Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class ParticipantsClient.

Service Description: Service for managing Participants.

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:

$participantsClient = new ParticipantsClient();
try {
    $formattedParticipant = $participantsClient->participantName('[PROJECT]', '[CONVERSATION]', '[PARTICIPANT]');
    $response = $participantsClient->analyzeContent($formattedParticipant);
} finally {
    $participantsClient->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\Dialogflow\V2\Client\ParticipantsClient to use the new surface.

Namespace

Google \ Cloud \ Dialogflow \ 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.

analyzeContent

Adds a text (chat, for example), or audio (phone recording, for example) message from a participant into the conversation.

Note: Always use agent versions for production traffic sent to virtual agents. See Versions and environments.

Parameters
Name	Description
`participant`	`string` Required. The name of the participant this text comes from. Format: `projects/<Project ID>/locations/<Location ID>/conversations/<Conversation ID>/participants/<Participant ID>`.
`optionalArgs`	`array` Optional.
`↳ textInput`	`TextInput` The natural language text to be processed.
`↳ eventInput`	`EventInput` An input event to send to Dialogflow.
`↳ suggestionInput`	`SuggestionInput` An input representing the selection of a suggestion.
`↳ replyAudioConfig`	`OutputAudioConfig` Speech synthesis configuration. The speech synthesis settings for a virtual agent that may be configured for the associated conversation profile are not used when calling AnalyzeContent. If this configuration is not supplied, speech synthesis is disabled.
`↳ queryParams`	`QueryParameters` Parameters for a Dialogflow virtual-agent query.
`↳ assistQueryParams`	`AssistQueryParameters` Parameters for a human assist query.
`↳ cxParameters`	`Struct` Additional parameters to be put into Dialogflow CX session parameters. To remove a parameter from the session, clients should explicitly set the parameter value to null. Note: this field should only be used if you are connecting to a Dialogflow CX agent.
`↳ requestId`	`string` A unique identifier for this request. Restricted to 36 ASCII characters. A random UUID is recommended. This request is only idempotent if a `request_id` is provided.
`↳ 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.

streamingAnalyzeContent

Adds a text (chat, for example), or audio (phone recording, for example) message from a participant into the conversation.

Note: This method is only available through the gRPC API (not REST).

The top-level message sent to the client by the server is StreamingAnalyzeContentResponse. Multiple response messages can be returned in order. The first one or more messages contain the recognition_result field. Each result represents a more complete transcript of what the user said. The next message contains the reply_text field and potentially the reply_audio field. The message can also contain the automated_agent_reply field.

Note: Always use agent versions for production traffic sent to virtual agents. See Versions and environments.
