LUIS 识别器方法停止工作（代码未更改）

Question

我没有更改任何代码，该方法抛出 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，但它确实有效。 BotBuilder 中似乎发生了一些变化，我不知道是什么。这是堆栈跟踪：

       Exception caught : Microsoft.Azure.CognitiveServices.Language.LUIS.Runtime.Models.APIErrorException: Operation returned an invalid status code 'Forbidden'

提前谢谢大家！

如果您使用 Starter Key 而不是来自 'endpoint runtime resource in Azure' 的实际 Subscription Key，就会发生这种情况。可以在此处找到更多信息：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：
