Sessions¶

class google.cloud.dialogflow_v2.services.sessions.SessionsAsyncClient(*, credentials: typing.Optional[google.auth.credentials.Credentials] = None, transport: typing.Optional[typing.Union[str, google.cloud.dialogflow_v2.services.sessions.transports.base.SessionsTransport, typing.Callable[[...], google.cloud.dialogflow_v2.services.sessions.transports.base.SessionsTransport]]] = 'grpc_asyncio', client_options: typing.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>)[source]¶

A service used for session interactions.

For more information, see the API interactions guide.

Instantiates the sessions async client.

Parameters

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 (Optional[Union[str,SessionsTransport,Callable[..., SessionsTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport to use. If a Callable is given, it will be called with the same set of initialization arguments as used in the SessionsTransport constructor. If set to None, a transport is chosen automatically.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “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).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS 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.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
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.

Raises

google.auth.exceptions.MutualTlsChannelError – If mutual TLS transport creation failed for any reason.

property api_endpoint¶

Return the API endpoint used by the client instance.

Returns: The API endpoint used by the client instance.
Return type: str

async cancel_operation(request: Optional[google.longrunning.operations_pb2.CancelOperationRequest] = None, *, retry: Optional[Union[google.api_core.retry.retry_unary_async.AsyncRetry, google.api_core.gapic_v1.method._MethodDefault]] = _MethodDefault._DEFAULT_VALUE, timeout: Union[float, object] = _MethodDefault._DEFAULT_VALUE, metadata: Sequence[Tuple[str, str]] = ()) → None[source]¶

async detect_intent(request: Optional[Union[google.cloud.dialogflow_v2.types.session.DetectIntentRequest, dict]] = None, *, session: Optional[str] = None, query_input: Optional[google.cloud.dialogflow_v2.types.session.QueryInput] = None, retry: Optional[Union[google.api_core.retry.retry_unary_async.AsyncRetry, google.api_core.gapic_v1.method._MethodDefault]] = _MethodDefault._DEFAULT_VALUE, timeout: Union[float, object] = _MethodDefault._DEFAULT_VALUE, metadata: Sequence[Tuple[str, str]] = ()) → google.cloud.dialogflow_v2.types.session.DetectIntentResponse[source]¶

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

If you might use Agent Assist or other CCAI products now or in the future, consider using [AnalyzeContent][google.cloud.dialogflow.v2.Participants.AnalyzeContent] instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

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

    async for response in stream:
        print(response)

Parameters

requests (AsyncIterator[google.cloud.dialogflow_v2.types.StreamingDetectIntentRequest]) –
The request object AsyncIterator. The top-level message sent by the client to the [Sessions.StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent] method.

Multiple request messages should be sent in order:
1. The first message must contain [session][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.session], [query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input] plus optionally [query_params][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_params]. If the client wants to receive an audio response, it should also contain [output_audio_config][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.output_audio_config]. The message must not contain [input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_audio].
2. If [query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input] was set to [query_input.audio_config][google.cloud.dialogflow.v2.InputAudioConfig], all subsequent messages must contain [input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_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][google.cloud.dialogflow.v2.QueryInput.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_async.AsyncRetry) – 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

The top-level message returned from the

StreamingDetectIntent method.

Multiple response messages can be returned in order:

If the StreamingDetectIntentRequest.input_audio field was set, the recognition_result field is populated for one or more messages. See the [StreamingRecognitionResult][google.cloud.dialogflow.v2.StreamingRecognitionResult] message for details about the result message sequence.
The next message contains response_id, query_result and optionally webhook_status if a WebHook was called.

Return type

AsyncIterable[google.cloud.dialogflow_v2.types.StreamingDetectIntentResponse]

A service used for session interactions.

For more information, see the API interactions guide.

Instantiates the sessions client.

Parameters

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 (Optional[Union[str,SessionsTransport,Callable[..., SessionsTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the SessionsTransport constructor. If set to None, a transport is chosen automatically.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “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).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS 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.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that the api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
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.

Raises

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

__exit__(type, value, traceback)[source]¶: Releases underlying transport’s resources.

Warning

ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

property api_endpoint¶

The length of the Session ID and User ID must not exceed 36 characters.

For more information, see the API interactions guide.

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

This corresponds to the session field on the request instance; if request is provided, this should not be set.
query_input (google.cloud.dialogflow_v2.types.QueryInput) –
Required. The input specification. It can be set to:
1. an audio config which instructs the
  speech recognizer how to process the speech audio,
2. a conversational query in the form of
  text, or
3. an event that specifies which intent
  to trigger.
This corresponds to the query_input field on the request instance; if request is provided, this should not be set.
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

The message returned from the DetectIntent method.

Return type

google.cloud.dialogflow_v2.types.DetectIntentResponse

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).

If you might use Agent Assist or other CCAI products now or in the future, consider using [StreamingAnalyzeContent][google.cloud.dialogflow.v2.Participants.StreamingAnalyzeContent] instead of StreamingDetectIntent. StreamingAnalyzeContent has additional functionality for Agent Assist and other CCAI products.

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

Parameters

requests (Iterator[google.cloud.dialogflow_v2.types.StreamingDetectIntentRequest]) –
The request object iterator. The top-level message sent by the client to the [Sessions.StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent] method.

Multiple request messages should be sent in order:
1. The first message must contain [session][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.session], [query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input] plus optionally [query_params][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_params]. If the client wants to receive an audio response, it should also contain [output_audio_config][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.output_audio_config]. The message must not contain [input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_audio].
2. If [query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input] was set to [query_input.audio_config][google.cloud.dialogflow.v2.InputAudioConfig], all subsequent messages must contain [input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_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][google.cloud.dialogflow.v2.QueryInput.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

The top-level message returned from the

StreamingDetectIntent method.

Multiple response messages can be returned in order:

If the StreamingDetectIntentRequest.input_audio field was set, the recognition_result field is populated for one or more messages. See the [StreamingRecognitionResult][google.cloud.dialogflow.v2.StreamingRecognitionResult] message for details about the result message sequence.
The next message contains response_id, query_result and optionally webhook_status if a WebHook was called.

Return type

Iterable[google.cloud.dialogflow_v2.types.StreamingDetectIntentResponse]
