使用 Bot Framework v4 代码时无法映射 LUIS 意图

Question

我正在运行 botframework v4 代码并使用 chatbot emulator 对其进行测试。目前我无法访问 luis 意图代码存在于 [MainDialog.cs][1] 中的代码流。

下面是 MainDialog.cs 文件中的一行：

 var luisResult = await _luisRecognizer.RecognizeAsync<FlightBooking>(stepContext.Context, cancellationToken);

但是，当我在 ChatBot 中输入一些消息时，每次流程都会在 [FlightBookingRecognizer.cs][2] 处结束，下面是我期望匹配/获取 luis 意图的行。

public virtual async Task<RecognizerResult> RecognizeAsync(ITurnContext turnContext, CancellationToken cancellationToken)
    => await _recognizer.RecognizeAsync(turnContext, cancellationToken);

public virtual async Task<T> RecognizeAsync<T>(ITurnContext turnContext, CancellationToken cancellationToken)
     where T : IRecognizerConvert, new()
    => await _recognizer.RecognizeAsync<T>(turnContext, cancellationToken);

turnContext 有我们在聊天机器人中输入的消息。 我期待 _recognizer.RecognizeAsync 中的 LUIS 结果，但其中没有相关数据。 我正在尝试执行以下操作：-

But, my code flow ends here and i get error in ChatBot emulator as attached in screenshot.[![enter image description here][3]][3]


Steps to reproduce:
1. Download or pull the project from github and then Open the CoreBot.csproj  in Visual studio from this link .
[CoreBot Project][4]

2. Then select CoreBot and build it (Don't forget to add luis app id,key and host in csharp_dotnetcore\13.core-bot\appsettings.json file).
In Luis you can import this file csharp_dotnetcore\13.core-bot\CognitiveModels\FlightBooking.json and then train and publish it.
In Luis.ai go to My apps, and click Import App. Choose the file JSON file for the app you want to import and click Import.

3. Also put debug breakpoints in MainDialog.cs class (line 67 jus before switch statement) and FlightBookingRecognizer.cs class (last 2 lines ) .

4.Run the project in IIS browser mode and not in console mode ,it will open in browser you will see this link  http://localhost:3978/ 

5. In chatbot Emulator open this link http://localhost:3979/api/messages

6. You will see cards in chatbot as per attached screenshot.

7. Enter a message which is given in chatbot example i.e "Flight to paris"

8. You will see debug point ends at FlightRecognizer.cs class last line and turnContext has your message but _recognizer.RecognizeAsync doesn't carry any information about the Luis intent .

9.Also,it is not clear that LUIS intent is matched from local file or luis.ai

V4 MessageController 应该很少（如果有的话）从骨架中改变。在这一行：

await _adapter.ProcessAsync(Request, response, _bot);

...您可以看到控制器将Request 传递给_bot。使用您的机器人来处理对话。

在the CoreBot sample中，可以看到消息打到BotController后（相当于MessageController，转到DialogBot，在那里调用Dialog：

protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
    Logger.LogInformation("Running dialog with Message Activity.");

    // Run the Dialog with the new message Activity.
    await Dialog.RunAsync(turnContext, ConversationState.CreateProperty<DialogState>("DialogState"), cancellationToken);
}

它“知道”这样做，因为在Startup.cs 中，它使用依赖注入来添加机器人和对话框，以便BotController 和DialogBot 可以分别使用它们：

services.AddTransient<IBot, DialogAndWelcomeBot<MainDialog>>();

在迁移之前，我强烈建议您设置 CoreBot 并通读它，直到您了解它的工作原理。这可能会对未来的迁移问题有所帮助。

这个问题现在已经解决了。我可以从 Luis 那里得到意图。 当我使用在 appsettings.json 中以https://xxxx.xxxx.xxxx 格式配置的 Luis 主机时 我没有得到 Luis Intent，但是在删除 https:// 之后，我现在得到了结果。 感谢大家的努力。
