Overview

Client for the Sessions service.

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.

Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new Sessions client object.

Examples

To create a new Sessions client with the default configuration:

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

Instance Method Details

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

Configure the Sessions 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.

#detect_intent(request, options = nil) ⇒ Google::Cloud::Dialogflow::V2::DetectIntentResponse #detect_intent(session: nil, query_params: nil, query_input: nil, output_audio_config: nil, output_audio_config_mask: nil, input_audio: nil) ⇒ Google::Cloud::Dialogflow::V2::DetectIntentResponse

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.

Overloads:

  • #detect_intent(request, options = nil) ⇒ Google::Cloud::Dialogflow::V2::DetectIntentResponse

    Parameters:

    • request (Google::Cloud::Dialogflow::V2::DetectIntentRequest | Hash) —

      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.

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

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

  • #detect_intent(session: nil, query_params: nil, query_input: nil, output_audio_config: nil, output_audio_config_mask: nil, input_audio: nil) ⇒ Google::Cloud::Dialogflow::V2::DetectIntentResponse

    Parameters:

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

      Required. The name of the session this query is sent to. 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 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_params (Google::Cloud::Dialogflow::V2::QueryParameters | Hash) (defaults to: nil) —

      The parameters of this query.

    • query_input (Google::Cloud::Dialogflow::V2::QueryInput | Hash) (defaults to: nil) —

      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.

    • output_audio_config (Google::Cloud::Dialogflow::V2::OutputAudioConfig | Hash) (defaults to: nil) —

      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.

    • output_audio_config_mask (Google::Protobuf::FieldMask | Hash) (defaults to: nil) —

      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.

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

      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.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (Google::Cloud::Error) —

    if the RPC is aborted.

#streaming_detect_intent(request, options = nil) {|response, operation| ... } ⇒ Enumerable<Google::Cloud::Dialogflow::V2::StreamingDetectIntentResponse>

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).

Parameters:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (Google::Cloud::Error) —

    if the RPC is aborted.
