调用 Dispatch/LUIS 模型时操作返回无效状态代码“未授权”

Question

我在从 bot 框架调用 Dispatch/LUIS 服务时收到以下错误消息。 我已经配置了 Microsoft APP ID 和密码，并且我也已部署到网络聊天中。 错误：操作返回了无效的状态码‘未授权’

来自机器人模拟器的 Json 结果

下面是代码

        {
            if (innerDc.Context.Activity.Type == ActivityTypes.Message)
            {
                // Get cognitive models for the current locale.
                var localizedServices = _services.GetCognitiveModels();


                // Run LUIS recognition and store result in turn state.
                var dispatchResult = await localizedServices.DispatchService.RecognizeAsync<DispatchLuis>(innerDc.Context, cancellationToken);
                innerDc.Context.TurnState.Add(StateProperties.DispatchResult, dispatchResult);

                if (dispatchResult.TopIntent().intent == DispatchLuis.Intent.l_ClientServices)
                {
                    // Run LUIS recognition on General model and store result in turn state.
                     generalResult = await localizedServices.LuisServices["General"].RecognizeAsync<GeneralLuis>(innerDc.Context, cancellationToken);
                    innerDc.Context.TurnState.Add(StateProperties.GeneralResult, generalResult);
                }
            }

            // Set up response caching for "repeat" functionality.
            innerDc.Context.OnSendActivities(StoreOutgoingActivities);
            return await base.OnContinueDialogAsync(innerDc, cancellationToken);
        }

请帮助我，我正在使用 Microsoft bot 框架 V4。

[我想我已经回答了这个问题，但不知何故我的回答消失了]

我认为您可能对 bot 本身的身份验证（即用户 bot 之间）以及 bot 和后端服务之间的身份验证（在本例中为 LUIS，即 bot LUIS）感到有些困惑。如果是这样，您需要获取您的 LUIS 应用程序 ID，您可以在 LUIS 应用的“管理”部分中获取该 ID，如下所示。

然后您需要订阅密钥，如下所示的“主密钥”。您还需要该区域，以指定正确的端点。在我的示例中，这是“westus”。

一旦你有了这些，你需要将它们注册到机器人本身，但你如何做取决于你如何配置你的机器人服务——看看你的“_services”是如何创建的，也许发送更多关于它正在寻找什么或它来自哪里的详细信息（例如，您使用了哪个启动项目）。
