使用 LUIS 对话框时出现异常

Question

我正在使用 bot 框架 SDK (3.8.2 / 3.8.3) 并在将 LUIS 对话框与 Bot Framework Emulator 一起使用时出现以下错误。

有什么想法吗？

例外：

;HelpWhoIsWhoDetailsFromName ['text/plain' 类型的文件]

（奇怪的是，无论我的意图是什么，异常前面都有一个';'）

您的问题是您在每个异步方法的参数中使用“LuisRequest”而不是“LuisResult”。据我所知，只有 LuisResult 有效。将您的代码更改为：

[Serializable]
[LuisModel("XXXXXXX-0ab19c3225cb", "XXXXXXXX582c599915aea4")] // changed the keys 
public class MatLuisDialog: LuisDialog<string>
{

    [LuisIntent("HelpWhoIsWhoDetailsFromName")]
    public async Task HelpWhoIsWhoDetailsFromName(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("From");
        context.Wait(MessageReceived);
    }

    [LuisIntent("")]
    [LuisIntent("None")]
    public async Task None(IDialogContext context, LuisResult result)
    {
    await context.PostAsync("No intent Found");
    context.Wait(MessageReceived);
    }

    [LuisIntent("Help.Greetings")]
    public async Task Greetings(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("Hi, Please enter your matone id, so that i can help you better.");
        context.Wait(MessageReceived);
    }

}
