Class SessionsClient (1.0.0) 

SessionsClient(
    transport=None,
    channel=None,
    credentials=None,
    client_config=None,
    client_info=None,
    client_options=None,
)

A session represents an interaction with a user. You retrieve user input and pass it to the DetectIntent (or StreamingDetectIntent) method to determine user intent and respond.

Methods

SessionsClient

SessionsClient(
    transport=None,
    channel=None,
    credentials=None,
    client_config=None,
    client_info=None,
    client_options=None,
)

Constructor.

Parameters
NameDescription
channel grpc.Channel

DEPRECATED. A Channel instance through which to make calls. This argument is mutually exclusive with credentials; providing both will raise an exception.

credentials google.auth.credentials.Credentials

The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to transport; doing so will raise an exception.

client_config dict

DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is 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.

client_options Union[dict, google.api_core.client_options.ClientOptions]

Client options used to set user options on the client. API Endpoint should be set through client_options.

detect_intent

detect_intent(session, query_input, query_params=None, output_audio_config=None, output_audio_config_mask=None, input_audio=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

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.

.. rubric:: Example

import dialogflow_v2beta1

client = dialogflow_v2beta1.SessionsClient()

session = client.session_path('[PROJECT]', '[SESSION]')

TODO: Initialize query_input:

query_input = {}

response = client.detect_intent(session, query_input)

Parameters
NameDescription
session str

Required. The name of the session this query is sent to. Format: projects/, or projects/. If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we are using "-". It's up to the API caller to choose an appropriate Session ID and User Id. They can be a random number or some type of user and session identifiers (preferably hashed). The length of the Session ID and User ID must not exceed 36 characters.

query_input Union[dict, 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. If a dict is provided, it must be of the same form as the protobuf message QueryInput

query_params Union[dict, QueryParameters]

The parameters of this query. If a dict is provided, it must be of the same form as the protobuf message QueryParameters

output_audio_config Union[dict, OutputAudioConfig]

Instructs the speech synthesizer how to generate the output audio. If this field is not set and agent-level speech synthesizer is not configured, no output audio is generated. If a dict is provided, it must be of the same form as the protobuf message OutputAudioConfig

output_audio_config_mask Union[dict, FieldMask]

Mask for output_audio_config indicating which settings in this request-level config should override speech synthesizer settings defined at agent-level. If unspecified or empty, output_audio_config replaces the agent-level config in its entirety. If a dict is provided, it must be of the same form as the protobuf message FieldMask

input_audio bytes

The natural language speech audio to be processed. This field should be populated iff query_input is set to an input audio config. A single request can contain up to 1 minute of speech audio data.

retry Optional[google.api_core.retry.Retry]

A retry object used to retry requests. If None is specified, requests will be retried using a default configuration.

timeout Optional[float]

The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

metadata Optional[Sequence[Tuple[str, str]]]

Additional metadata that is provided to the method.

Exceptions
TypeDescription
google.api_core.exceptions.GoogleAPICallErrorIf the request failed for any reason.
google.api_core.exceptions.RetryErrorIf the request failed due to a retryable error and retry attempts failed.
ValueErrorIf the parameters are invalid.

environment_session_path

environment_session_path(project, environment, user, session)

Return a fully-qualified environment_session string.

from_service_account_file

from_service_account_file(filename, *args, **kwargs)

Creates an instance of this client using the provided credentials file.

Parameter
NameDescription
filename str

The path to the service account private key json file.

Returns
TypeDescription
dialogflow_v2beta1.SessionsClientThe constructed client.

from_service_account_json

from_service_account_json(filename, *args, **kwargs)

Creates an instance of this client using the provided credentials file.

Parameter
NameDescription
filename str

The path to the service account private key json file.

Returns
TypeDescription
dialogflow_v2beta1.SessionsClientThe constructed client.

session_path

session_path(project, session)

Return a fully-qualified session string.

streaming_detect_intent

streaming_detect_intent(requests, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

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).

.. rubric:: Example

import dialogflow_v2beta1

client = dialogflow_v2beta1.SessionsClient()

TODO: Initialize session:

session = ''

TODO: Initialize query_input:

query_input = {} request = {'session': session, 'query_input': query_input}

requests = [request] for element in client.streaming_detect_intent(requests): ... # process element ... pass

Parameters
NameDescription
requests iterator[dict|google.cloud.dialogflow_v2beta1.proto.session_pb2.StreamingDetectIntentRequest]

The input objects. If a dict is provided, it must be of the same form as the protobuf message StreamingDetectIntentRequest

retry Optional[google.api_core.retry.Retry]

A retry object used to retry requests. If None is specified, requests will be retried using a default configuration.

timeout Optional[float]

The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

metadata Optional[Sequence[Tuple[str, str]]]

Additional metadata that is provided to the method.

Exceptions
TypeDescription
google.api_core.exceptions.GoogleAPICallErrorIf the request failed for any reason.
google.api_core.exceptions.RetryErrorIf the request failed due to a retryable error and retry attempts failed.
ValueErrorIf the parameters are invalid.
