在Watson Assistant V2中对任何查询获得相同的响应：Watson-Unity-SDK

Question

I just got to a point where I could set-up the Watson Assistant V2 with Unity and trying to converse with an Assistant I created with a single Skill. I need further help to get the assistant set up to work with my Unity app.

In V1 of the assistant, it was possible to target a workspace and also the response was returning the intent, nodes visited so on. My queries were correctly processed and the responses were identical to the one on the "try it" application in the IBM cloud dashboard.

In the new version though, I am getting the same response for any query I send to the assistant. How can I target the right skill or rather pass correct settings to the assistant to get the correct responses?

The code I'm using to send queries and get responses is:

IEnumerator TokenExample()
{
    //  Create IAM token options and supply the apikey. IamUrl is the URL used to get the 
    //  authorization token using the IamApiKey. It defaults to https://iam.bluemix.net/identity/token
    TokenOptions iamTokenOptions = new TokenOptions()
    {
        IamApiKey = "API KEY",
        IamUrl = "https://iam.bluemix.net/identity/token"

    };
    //  Create credentials using the IAM token options

    _credentials = new Credentials(iamTokenOptions, "https://gateway-fra.watsonplatform.net/assistant/api");
    while (!_credentials.HasIamTokenData())
        yield return null;

    _assistant = new Assistant(_credentials);
    _assistant.VersionDate = "2018-11-01";

    Debug.Log(_assistant.GetServiceID()); // returns "AssitantV2"

}

public void PingAssistantV2() // triggered from a button press in UI
{
    _assistant.CreateSession(OnCreateSession, OnFail, AssistantID); // Assistant ID is entered through the Inspector

}

public void OnCreateSession(SessionResponse response, Dictionary<string, object> customData)
{
    Log.Debug("ExampleAssistantV2.OnMessage()", "Assistant: Create Session Response: {0}", customData["json"].ToString());

    string _si = response.SessionId;
    Debug.Log("SessionID: " +_si);

    MessageInput mi = new MessageInput();
    mi.Text = Query.textComponent.text; // get user query from an input field in unity UI


    MessageRequest messageRequest = new MessageRequest()
    {
        Input = mi

    };
    Debug.LogFormat("<b> Query Sent: {0} </b>", Query.textComponent.text);
    if (response.SessionId != null ) _assistant.Message(OnMessage, OnFail, AssistantID, _si, messageRequest);
}

private void OnMessage(MessageResponse AssistantResponse, Dictionary<string, object> customData)
{
    Log.Debug("ExampleAssistant.OnMessage()", "Response: {0}", customData["json"].ToString());
    Debug.LogFormat("<b> SUCCESS </b>");
    Debug.Log(customData["json"].ToString());

    //  Convert resp to fsdata
    fsData fsdata = null;
    fsResult r = _serializer.TrySerialize(AssistantResponse.GetType(), AssistantResponse, out fsdata);
    if (!r.Succeeded)
        throw new WatsonException(r.FormattedMessages);

    //  Convert fsdata to MessageResponse
    IBM.WatsonDeveloperCloud.Assistant.v2.MessageResponse messageResponse = new IBM.WatsonDeveloperCloud.Assistant.v2.MessageResponse();
    object obj = messageResponse;
    r = _serializer.TryDeserialize(fsdata, obj.GetType(), ref obj);
    if (!r.Succeeded)
        throw new WatsonException(r.FormattedMessages);

    Response.text = AssistantResponse.Output.Generic.First().Text; // send response to unity UI text box

}

private void OnFail(RESTConnector.Error error, Dictionary<string, object> customData)
{
    Log.Debug("OnFail()", "Failed: {0}", error.ToString());
    Debug.LogFormat("<b> Failed </b>");
    Debug.Log(error.ToString());
}

EDIT to address @Taj's comment

The Issue persists even with the sample for assitant V2 in the SDK:

Answer 1

I can see from your log that you have a new sessionId each time you message. You do not need to create a session each time you send a message. The session should persist during the conversation. I moved the call to CreateSession to your TokenExample() and call PingAssistantV2() once you have a sessionId.

string _si = "";

IEnumerator TokenExample()
{
    //  Create IAM token options and supply the apikey. IamUrl is the URL used to get the 
    //  authorization token using the IamApiKey. It defaults to https://iam.bluemix.net/identity/token
    TokenOptions iamTokenOptions = new TokenOptions()
    {
        IamApiKey = "API KEY",
        IamUrl = "https://iam.bluemix.net/identity/token"

    };
    //  Create credentials using the IAM token options

    _credentials = new Credentials(iamTokenOptions, "https://gateway-fra.watsonplatform.net/assistant/api");
    while (!_credentials.HasIamTokenData())
        yield return null;

    _assistant = new Assistant(_credentials);
    _assistant.VersionDate = "2018-11-01";

    Debug.Log(_assistant.GetServiceID()); // returns "AssitantV2"

    _assistant.CreateSession(OnCreateSession, OnFail, AssistantID); // Assistant ID is entered through the Inspector
}

public void PingAssistantV2() // triggered from a button press in UI
{
    MessageInput mi = new MessageInput();
    mi.Text = Query.textComponent.text; // get user query from an input field in unity UI

    MessageRequest messageRequest = new MessageRequest()
    {
        Input = mi

    };
    Debug.LogFormat("<b> Query Sent: {0} </b>", Query.textComponent.text);
    if (response.SessionId != null ) _assistant.Message(OnMessage, OnFail, AssistantID, _si, messageRequest);
}

public void OnCreateSession(SessionResponse response, Dictionary<string, object> customData)
{
    Log.Debug("ExampleAssistantV2.OnMessage()", "Assistant: Create Session Response: {0}", customData["json"].ToString());

    _si = response.SessionId;
    Debug.Log("SessionID: " +_si);

    PingAssistantV2();
}

private void OnMessage(MessageResponse AssistantResponse, Dictionary<string, object> customData)
{
    Log.Debug("ExampleAssistant.OnMessage()", "Response: {0}", customData["json"].ToString());
    Debug.LogFormat("<b> SUCCESS </b>");
    Debug.Log(customData["json"].ToString());

    //  Convert resp to fsdata
    fsData fsdata = null;
    fsResult r = _serializer.TrySerialize(AssistantResponse.GetType(), AssistantResponse, out fsdata);
    if (!r.Succeeded)
        throw new WatsonException(r.FormattedMessages);

    //  Convert fsdata to MessageResponse
    IBM.WatsonDeveloperCloud.Assistant.v2.MessageResponse messageResponse = new IBM.WatsonDeveloperCloud.Assistant.v2.MessageResponse();
    object obj = messageResponse;
    r = _serializer.TryDeserialize(fsdata, obj.GetType(), ref obj);
    if (!r.Succeeded)
        throw new WatsonException(r.FormattedMessages);

    Response.text = AssistantResponse.Output.Generic.First().Text; // send response to unity UI text box

}

private void OnFail(RESTConnector.Error error, Dictionary<string, object> customData)
{
    Log.Debug("OnFail()", "Failed: {0}", error.ToString());
    Debug.LogFormat("<b> Failed </b>");
    Debug.Log(error.ToString());
}
