Overview

Client for the Contexts service.

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.

#initialize {|config| ... } ⇒ Client

Create a new Contexts client object.

Examples

To create a new Contexts client with the default configuration:

client = ::Google::Cloud::Dialogflow::V2::Contexts::Client.new

To create a new Contexts client with a custom configuration:

client = ::Google::Cloud::Dialogflow::V2::Contexts::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Contexts client.

#configure {|config| ... } ⇒ Client::Configuration

Configure the Contexts Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The session to create a context for. Format: projects/<Project ID>/agent/sessions/<Session ID> or projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>. If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we assume default '-' user.

    • context (::Google::Cloud::Dialogflow::V2::Context, ::Hash) (defaults to: nil) —

      Required. The context to create.

If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we assume default '-' user.

    • page_size (::Integer) (defaults to: nil) —

      Optional. The maximum number of items to return in a single page. By default 100 and at most 1000.

    • page_token (::String) (defaults to: nil) —

      Optional. The next_page_token value returned from a previous list request.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#update_context(request, options = nil) ⇒ ::Google::Cloud::Dialogflow::V2::Context #update_context(context: nil, update_mask: nil) ⇒ ::Google::Cloud::Dialogflow::V2::Context

Updates the specified context.

Overloads:

  • #update_context(request, options = nil) ⇒ ::Google::Cloud::Dialogflow::V2::Context

    Pass arguments to update_context via a request object, either of type UpdateContextRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Dialogflow::V2::UpdateContextRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #update_context(context: nil, update_mask: nil) ⇒ ::Google::Cloud::Dialogflow::V2::Context

    Pass arguments to update_context via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
