Class ContextsClient (1.0.0)

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

A context represents additional information included with user input or with an intent returned by the Dialogflow API. Contexts are helpful for differentiating user input which may be vague or have a different meaning depending on additional details from your application such as user setting and preferences, previous user input, where the user is in your application, geographic location, and so on.

You can include contexts as input parameters of a DetectIntent (or StreamingDetectIntent) request, or as output contexts included in the returned intent. Contexts expire when an intent is matched, after the number of DetectIntent requests specified by the lifespan_count parameter, or after 20 minutes if no intents are matched for a DetectIntent request.

For more information about contexts, see the Dialogflow documentation <https://cloud.google.com/dialogflow/docs/contexts-overview>__.

Methods

ContextsClient

ContextsClient(
    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.

context_path

context_path(project, session, context)

Return a fully-qualified context string.

create_context

create_context(parent, context, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Creates a context.

If the specified context already exists, overrides the context.

.. rubric:: Example

import dialogflow_v2beta1

client = dialogflow_v2beta1.ContextsClient()

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

TODO: Initialize context:

Parameters
NameDescription

Required. The session to create a context for. Format: projects/ or projects/. If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we assume default '-' user.
