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

Question

我刚刚达到可以使用Unity设置Watson Assistant V2并尝试与使用单个Skill创建的Assistant交谈的程度。 我需要进一步的帮助来设置助手以与我的Unity应用程序一起使用。

在助手的V1中，可以将工作空间定位为目标，并且响应正在返回意图，访问的节点等等。 我的查询已正确处理，并且响应与IBM云仪表板中“ try it”应用程序中的响应相同。

但是在新版本中，我发送给助手的任何查询都会得到相同的响应。 我该如何定位正确的技能，或者将正确的设置传递给助手以获得正确的答案？

我用来发送查询和获取响应的代码是：

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());
}

即使使用SDK中辅助V2的示例，问题仍然存在：

Answer 1

从您的日志中可以看到，每次发送消息时您都有一个新的sessionId。 您无需在每次发送消息时都创建会话。 会话应在会话期间持续进行。 我将对CreateSession的调用移至您的TokenExample()并在您获得sessionId后调用PingAssistantV2() 。

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());
}
