Class SessionsClient (1.13.0)

SessionsClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.dialogflowcx_v3beta1.services.sessions.transports.base.SessionsTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

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.

Inheritance

Properties

transport

Returns the transport used by the client instance.

Returns

Type	Description
SessionsTransport	The transport used by the client instance.

Methods

SessionsClient

SessionsClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.dialogflowcx_v3beta1.services.sessions.transports.base.SessionsTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the sessions client.

Parameters

Name	Description
credentials	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
transport	`Union[str, SessionsTransport]` The transport to use. If set to None, a transport is chosen automatically.
client_options	`google.api_core.client_options.ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
client_info	`google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions

Type	Description
google.auth.exceptions.MutualTLSChannelError	If mutual TLS transport creation failed for any reason.

exit

__exit__(type, value, traceback)

Releases underlying transport's resources.

cancel_operation

cancel_operation(request: Optional[google.longrunning.operations_pb2.CancelOperationRequest] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Starts asynchronous cancellation on a long-running operation.

The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Parameters

Name	Description
request	`.operations_pb2.CancelOperationRequest` The request object. Request message for `CancelOperation` method.
retry	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.

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 <https://cloud.google.com/dialogflow/cx/docs/concept/version>__.

Processes a natural language query in audio format in a streaming fashion and returns structured, actionable data as a result. This method is only available via the gRPC API (not REST).

Note: Always use agent versions for production traffic. See Versions and environments <https://cloud.google.com/dialogflow/cx/docs/concept/version>__.

from google.cloud import dialogflowcx_v3beta1

def sample_streaming_detect_intent():
    # Create a client
    client = dialogflowcx_v3beta1.SessionsClient()

    # Initialize request argument(s)
    query_input = dialogflowcx_v3beta1.QueryInput()
    query_input.text.text = "text_value"
    query_input.language_code = "language_code_value"

    request = dialogflowcx_v3beta1.StreamingDetectIntentRequest(
        query_input=query_input,
    )

    # This method expects an iterator which contains
    # 'dialogflowcx_v3beta1.StreamingDetectIntentRequest' objects
    # Here we create a generator that yields a single `request` for
    # demonstrative purposes.
    requests = [request]

    def request_generator():
        for request in requests:
            yield request

    # Make the request
    stream = client.streaming_detect_intent(requests=request_generator())

    # Handle the response
    for response in stream:
        print(response)

Parameters

Name	Description
requests	`Iterator[google.cloud.dialogflowcx_v3beta1.types.StreamingDetectIntentRequest]` The request object iterator. The top-level message sent by the client to the Sessions.StreamingDetectIntent method. Multiple request messages should be sent in order: 1. The first message must contain session, query_input plus optionally query_params. If the client wants to receive an audio response, it should also contain output_audio_config. 2. If query_input was set to query_input.audio.config, all subsequent messages must contain query_input.audio.audio to continue with Speech recognition. If you decide to rather detect an intent from text input after you already started Speech recognition, please send a message with query_input.text. However, note that: * Dialogflow will bill you for the audio duration so far. * Dialogflow discards all Speech recognition results in favor of the input text. * Dialogflow will use the language code from the first message. After you sent all input, you must half-close or abort the request stream.
retry	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
timeout	`float` The timeout for this request.
metadata	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns

Type

Description

Iterable[google.cloud.dialogflowcx_v3beta1.types.StreamingDetectIntentResponse]

The top-level message returned from the StreamingDetectIntent method. Multiple response messages (N) can be returned in order. The first (N-1) responses set either the recognition_result or detect_intent_response field, depending on the request: - If the StreamingDetectIntentRequest.query_input.audio field was set, and the StreamingDetectIntentRequest.enable_partial_response field was false, the recognition_result field is populated for each of the (N-1) responses. See the StreamingRecognitionResult message for details about the result message sequence. - If the StreamingDetectIntentRequest.enable_partial_response field was true, the detect_intent_response field is populated for each of the (N-1) responses, where 1 <= n=""><= 4.="" these="" responses="" set="" the="">DetectIntentResponse.response_type field to PARTIAL. For the final Nth response message, the detect_intent_response is fully populated, and DetectIntentResponse.response_type is set to FINAL.
