LUIS识别器方法停止工作（代码未更改）

Question

我没有改变我的任何代码，该方法抛出一个LUIS.Runtime.Models.APIErrorException

_services.LuisServices[LuisConfiguration].RecognizeAsync(turnContext, cancellationToken);

我尝试使用不同的LUIS模型和我的机器人的旧版本，肯定有用。似乎BotBuilder中的某些内容发生了变化，我无法弄清楚是什么。这是堆栈跟踪：

       Exception caught : Microsoft.Azure.CognitiveServices.Language.LUIS.Runtime.Models.APIErrorException: Operation returned an invalid status code 'Forbidden'
        at Microsoft.Azure.CognitiveServices.Language.LUIS.Runtime.Prediction.ResolveWithHttpMessagesAsync(String appId, String query, 
        Nullable`1 timezoneOffset, Nullable`1 verbose, 
        Nullable`1 staging, Nullable`1 spellCheck, String bingSpellCheckSubscriptionKey,
 Nullable`1 log, Dictionary`2 customHeaders, CancellationToken cancellationToken)
                 at Microsoft.Azure.CognitiveServices.Language.LUIS.Runtime.PredictionExtensions.ResolveAsync(IPrediction operations, String appId, String query, 
    Nullable`1 timezoneOffset, Nullable`1 verbose, 
    Nullable`1 staging, 
    Nullable`1 spellCheck, 
    String bingSpellCheckSubscriptionKey, Nullable`1 log, CancellationToken cancellationToken)
                 at Microsoft.Bot.Builder.AI.Luis.LuisRecognizer
    .RecognizeInternalAsync(ITurnContext turnContext, CancellationToken cancellationToken) in D:\a\1\s\libraries\Microsoft.Bot.Builder.AI.LUIS
    \LuisRecognizer.cs:line 421
                 at Microsoft.Bot.Builder.AI.Luis.LuisRecognizer
    .RecognizeAsync(ITurnContext turnContext, CancellationToken cancellationToken) in D:\a\1\s\libraries\Microsoft.Bot.Builder.AI.LUIS
    \LuisRecognizer.cs:line 112
                 at NLPMortBot.BasicBot.OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken) in nlpmortbot\NLPMortBot\BasicBot.cs:line 121
                 at Microsoft.Bot.Builder.MiddlewareSet.ReceiveActivityWithStatusAsync(ITurnContext turnContext, BotCallbackHandler callback, 

在D：\ a \ 1 \ s \ libraries \ Microsoft.Bot.Builder \ MiddlewareSet.cs中的CancellationToken cancellationToken）：在D中的Microsoft.Bot.Builder.BotAdapter.RunPipelineAsync（ITurnContext turnContext，BotCallbackHandler callback，CancellationToken cancellationToken）中的第55行： \ a \ 1 \ s \ libraries \ Microsoft.Bot.Builder \ BotAdapter.cs：第167行

先谢谢你们！

如果您使用Starter Key而不是Azure中的“端点运行时资源”中的实际订阅密钥，则会发生这种情况。更多信息可以在这里找到：https://docs.microsoft.com/en-us/azure/cognitive-services/luis/luis-how-to-azure-subscription

创建LUIS Azure资源密钥后，可以在LUIS门户中分配它：
