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
Name	Description
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_v2

client = dialogflow_v2.SessionsClient()

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

TODO: Initialize query_input:

query_input = {}

response = client.detect_intent(session, query_input)

Parameters
Name	Description
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
Type	Description
google.api_core.exceptions.GoogleAPICallError	If the request failed for any reason.
google.api_core.exceptions.RetryError	If the request failed due to a retryable error and retry attempts failed.
ValueError	If the parameters are invalid.

from_service_account_file

from_service_account_file(filename, *args, **kwargs)

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

Parameter
Name	Description
filename	str The path to the service account private key json file.

Returns
Type	Description
dialogflow_v2.SessionsClient	The 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
Name	Description
filename	str The path to the service account private key json file.

Returns
Type	Description
dialogflow_v2.SessionsClient	The 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_v2

client = dialogflow_v2.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
Name	Description
requests	iterator[dict|google.cloud.dialogflow_v2.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
Type	Description
google.api_core.exceptions.GoogleAPICallError	If the request failed for any reason.
google.api_core.exceptions.RetryError	If the request failed due to a retryable error and retry attempts failed.
ValueError	If the parameters are invalid.
