Methods

Create()

Synchronously creates a SessionsClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use SessionsClientBuilder.

Declaration

public static SessionsClient Create()

Returns

Type	Description
SessionsClient	The created SessionsClient.

CreateAsync(CancellationToken)

Asynchronously creates a SessionsClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use SessionsClientBuilder.

Declaration

public static Task<SessionsClient> CreateAsync(CancellationToken cancellationToken = default)

Parameters

Type	Name	Description
CancellationToken	cancellationToken	The CancellationToken to use while creating the client.

Returns

Type	Description
Task<SessionsClient>	The task representing the created SessionsClient.

DetectIntent(DetectIntentRequest, CallSettings)

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.

If you might use Agent Assist or other CCAI products now or in the future, consider using [AnalyzeContent][google.cloud.dialogflow.v2.Participants.AnalyzeContent] instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

Note: Always use agent versions for production traffic. See Versions and environments.

Declaration

public virtual DetectIntentResponse DetectIntent(DetectIntentRequest request, CallSettings callSettings = null)

Parameters

Type	Name	Description
DetectIntentRequest	request	The request object containing all of the parameters for the API call.
CallSettings	callSettings	If not null, applies overrides to this RPC call.

Returns

Type	Description
DetectIntentResponse	The RPC response.

Sample code

// Create client
SessionsClient sessionsClient = SessionsClient.Create();
// Initialize request argument(s)
DetectIntentRequest request = new DetectIntentRequest
{
    SessionAsSessionName = SessionName.FromProjectSession("[PROJECT]", "[SESSION]"),
    QueryParams = new QueryParameters(),
    QueryInput = new QueryInput(),
    OutputAudioConfig = new OutputAudioConfig(),
    InputAudio = ByteString.Empty,
    OutputAudioConfigMask = new FieldMask(),
};
// Make the request
DetectIntentResponse response = sessionsClient.DetectIntent(request);

DetectIntent(SessionName, QueryInput, CallSettings)

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.

If you might use Agent Assist or other CCAI products now or in the future, consider using [AnalyzeContent][google.cloud.dialogflow.v2.Participants.AnalyzeContent] instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

Note: Always use agent versions for production traffic. See Versions and environments.

Declaration

public virtual DetectIntentResponse DetectIntent(SessionName session, QueryInput queryInput, CallSettings callSettings = null)

Parameters

Type	Name	Description
SessionName	session	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 (Environment ID might be referred to as environment name at some places). 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. For more information, see the API interactions guide. Note: Always use agent versions for production traffic. See Versions and environments.
QueryInput	queryInput	Required. The input specification. It can be set to: an audio config which instructs the speech recognizer how to process the speech audio, a conversational query in the form of text, or an event that specifies which intent to trigger.
CallSettings	callSettings	If not null, applies overrides to this RPC call.

Returns

Type	Description
DetectIntentResponse	The RPC response.

Sample code

// Create client
SessionsClient sessionsClient = SessionsClient.Create();
// Initialize request argument(s)
SessionName session = SessionName.FromProjectSession("[PROJECT]", "[SESSION]");
QueryInput queryInput = new QueryInput();
// Make the request
DetectIntentResponse response = sessionsClient.DetectIntent(session, queryInput);

Parameters

Type	Name	Description
CallSettings	callSettings	If not null, applies overrides to this RPC call.
BidirectionalStreamingSettings	streamingSettings	If not null, applies streaming overrides to this RPC call.

Returns

Type	Description
SessionsClient.StreamingDetectIntentStream	The client-server stream.

Sample code

// Create client
SessionsClient sessionsClient = SessionsClient.Create();
// Initialize streaming call, retrieving the stream object
using SessionsClient.StreamingDetectIntentStream response = sessionsClient.StreamingDetectIntent();

// Sending requests and retrieving responses can be arbitrarily interleaved
// Exact sequence will depend on client/server behavior

// Create task to do something with responses from server
Task responseHandlerTask = Task.Run(async () =>
{
    // Note that C# 8 code can use await foreach
    AsyncResponseStream<StreamingDetectIntentResponse> responseStream = response.GetResponseStream();
    while (await responseStream.MoveNextAsync())
    {
        StreamingDetectIntentResponse responseItem = responseStream.Current;
        // Do something with streamed response
    }
    // The response stream has completed
});

// Send requests to the server
bool done = false;
while (!done)
{
    // Initialize a request
    StreamingDetectIntentRequest request = new StreamingDetectIntentRequest
    {
        SessionAsSessionName = SessionName.FromProjectSession("[PROJECT]", "[SESSION]"),
        QueryParams = new QueryParameters(),
        QueryInput = new QueryInput(),
        OutputAudioConfig = new OutputAudioConfig(),
        InputAudio = ByteString.Empty,
        OutputAudioConfigMask = new FieldMask(),
        EnableDebuggingInfo = false,
    };
    // Stream a request to the server
    await response.WriteAsync(request);
    // Set "done" to true when sending requests is complete
}

// Complete writing requests to the stream
await response.WriteCompleteAsync();
// Await the response handler
// This will complete once all server responses have been processed
await responseHandlerTask;
