我刚刚达到可以使用 Unity 设置 Watson Assistant V2 并尝试与使用单一技能创建的助手对话的地步。我需要进一步的帮助来设置助手以使用我的 Unity 应用程序。
在助手的 V1 中，可以定位工作区，并且响应返回意图、访问的节点等等。我的查询得到了正确处理，并且响应与 IBM 云仪表板中“试用”应用程序中的响应相同。
不过，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。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响应？
[IMAGE - 仪表板上的助手试用][2]
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());
}
编辑以解决@Taj 的评论
即使使用 SDK 中的助手 V2 示例，问题仍然存在：
