Luis集成拋出錯誤

我已經開始將Luis集成到我的BOT中，LUIS查詢在瀏覽器中很好用，但它似乎在通過代碼調用時從LUIS GetResult返回的內容拋出錯誤。Luis集成拋出錯誤

的LUIS查詢對話框here

的源代碼：

[LuisModel("2d3e39d8-632a-4e00-bf2f-d98ea4b2ed79&", "subscription Key")] 
    [Serializable] 
    public class SupportDialog : LuisDialog<object> 
    { 

     [LuisIntent("")] 
     public async Task None(IDialogContext context, LuisResult result) 
     { 
      await context.PostAsync("Sorry, I dont understand what you need"); 
      context.Wait(MessageReceived); 
     } 


     [LuisIntent("OrderStatus")] 
     public async Task OrderStatus(IDialogContext context, LuisResult result) 
     { 
      var returnMsg = "You wanted to check the order status"; 
      var orderStatus = "Dispatched"; 
      var deliveryDate = DateTime.Now.AddDays(3); 

      var entities = new List<EntityRecommendation>(result.Entities); 
      if(entities.Any((entity)=> entity.Type == "Order")) 
      { 
       var orderEntity = entities.Where((entity) => entity.Type == "Order").FirstOrDefault(); 
       var resolutionStr = orderEntity.Resolution.FirstOrDefault().Value ?? null; 
       if(!string.IsNullOrEmpty(resolutionStr)) 
       { 
        returnMsg = "Your order " + resolutionStr + " status is " + orderStatus + " and expected to deliver by " + deliveryDate.Humanize(); 
       } 
      } 

      await context.PostAsync(returnMsg); 
      context.Wait(MessageReceived); 
     } 

    }

MessageController源代碼：

internal static IDialog<object> MakeRoot() 
     { 
      return Chain.From(() => new SupportDialog()); 
     } 

     [ResponseType(typeof(void))] 
     public virtual async Task<HttpResponseMessage> Post([FromBody] Activity activity) 
     { 
      if (activity != null) 
      { 
       // one of these will have an interface and process it 
       switch (activity.GetActivityType()) 
       { 
        case ActivityTypes.Message: 
         await Conversation.SendAsync(activity, MakeRoot); 
         break; 

        case ActivityTypes.ConversationUpdate: 
        case ActivityTypes.ContactRelationUpdate: 
        case ActivityTypes.Typing: 
        case ActivityTypes.DeleteUserData: 
        default: 
         Trace.TraceError($"Unknown activity type ignored: {activity.GetActivityType()}"); 
         break; 
       } 
      } 
      return new HttpResponseMessage(System.Net.HttpStatusCode.Accepted); 
     }

在LuisModel刪除＆符號。

我想你是不小心將它從URL中複製過來的。

此外，更改您在代碼中發佈的訂閱密鑰，否則我們會盜取它。

對不起，但你提到的是＆符號，但我不需要在我的代碼中的任何地方引用直接的LUIS模型URL ，對吧？ – Vikram

這是一個免費試用版，所以不會持續很長時間;） – Vikram

我的意思是你的luismodel屬性中的「＆」標誌。嘗試刪除它，這是一個錯字。 – K48

有一行代碼會拋出一個空引用異常：

var resolutionStr = orderEntity.Resolution.FirstOrDefault().Value ?? null;

嘗試下一個方式改寫：

var resolutionStr = orderEntity.Resolution.FirstOrDefault()?.Value;

問題是，當我嘗試調試它時，它甚至不在函數內部。我剛剛嘗試評論整個部分，除了硬編碼的返回消息，即使如此它也會引發相同的錯誤。它似乎是由Luis Intent屬性本身引起的:-( – Vikram

也請附上你的API控制器的代碼 –

這下面的錯誤也可能會出現;當您發佈LUIS應用下舞臺插槽

Response status code does not indicate success: 400 (Bad Request)

所以總是發佈下採油槽LUIS應用

而且很明顯，你必須刪除符號（& ）從你的LuisModel ID登錄。

我同意生產插槽與臨時插槽的使用 - 我會追加 - 確保Luis應用程序培訓和發佈已完成 - 端點密鑰和應用程序ID是甚至在它發生之前可用 –
