#analyze_content

def analyze_content(request, options = nil) -> ::Google::Cloud::Dialogflow::V2::AnalyzeContentResponse
def analyze_content(participant: nil, text_input: nil, event_input: nil, suggestion_input: nil, reply_audio_config: nil, query_params: nil, assist_query_params: nil, cx_parameters: nil, request_id: nil) -> ::Google::Cloud::Dialogflow::V2::AnalyzeContentResponse

Adds a text (chat, for example), or audio (phone recording, for example) message from a participant into the conversation.

Note: Always use agent versions for production traffic sent to virtual agents. See Versions and environments.

Overloads
def analyze_content(request, options = nil) -> ::Google::Cloud::Dialogflow::V2::AnalyzeContentResponse
Pass arguments to analyze_content via a request object, either of type AnalyzeContentRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Dialogflow::V2::AnalyzeContentRequest, ::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) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional.
def analyze_content(participant: nil, text_input: nil, event_input: nil, suggestion_input: nil, reply_audio_config: nil, query_params: nil, assist_query_params: nil, cx_parameters: nil, request_id: nil) -> ::Google::Cloud::Dialogflow::V2::AnalyzeContentResponse
Pass arguments to analyze_content 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
  • participant (::String) — Required. The name of the participant this text comes from. Format: projects/<Project ID>/locations/<Location ID>/conversations/<Conversation ID>/participants/<Participant ID>.
  • text_input (::Google::Cloud::Dialogflow::V2::TextInput, ::Hash) — The natural language text to be processed.
  • event_input (::Google::Cloud::Dialogflow::V2::EventInput, ::Hash) — An input event to send to Dialogflow.

  • reply_audio_config (::Google::Cloud::Dialogflow::V2::OutputAudioConfig, ::Hash) — Speech synthesis configuration. The speech synthesis settings for a virtual agent that may be configured for the associated conversation profile are not used when calling AnalyzeContent. If this configuration is not supplied, speech synthesis is disabled.
  • query_params (::Google::Cloud::Dialogflow::V2::QueryParameters, ::Hash) — Parameters for a Dialogflow virtual-agent query.
  • assist_query_params (::Google::Cloud::Dialogflow::V2::AssistQueryParameters, ::Hash) — Parameters for a human assist query.
  • cx_parameters (::Google::Protobuf::Struct, ::Hash) — Additional parameters to be put into Dialogflow CX session parameters. To remove a parameter from the session, clients should explicitly set the parameter value to null.

    Note: this field should only be used if you are connecting to a Dialogflow CX agent.

  • request_id (::String) — A unique identifier for this request. Restricted to 36 ASCII characters. A random UUID is recommended. This request is only idempotent if a request_id is provided.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
Example

Basic example

require "google/cloud/dialogflow/v2"

# The returned object is of type Google::Cloud::Dialogflow::V2::AnalyzeContentResponse.
p result

#configure

def configure() { |config| ... } -> Client::Configuration

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
