c# - 更新到 1.2.0.1 后 LuisDialog 不再工作

Question

我已经更新了我的 NuGet 包以使用 Microsoft Bot Framework 1.2.0.1 版。

一些重大变化是 reported here ，并且我设法修复了构建错误。但是应用程序不再工作了..

我有两个问题:

1. 当我向 Controller 发送消息或话语时，代码会抛出 InvalidIntentHandlerException。

2. 在我的“intent”方法(装饰有 LuisIntent 属性)中，可以读取实体的值。像这样:

   [Serializable]
   [LuisModel("xxxxx", "xxxx")]
   public class BookFlightDialog : LuisDialog<BookFlightForm>
   {
       private readonly BuildFormDelegate<BookFlightForm> BuildForm;
   
       internal BookFlightDialog(BuildFormDelegate<BookFlightForm> buildForm)
       {
           BuildForm = buildForm;
       }
   
       [LuisIntent("")]
       [LuisIntent("None")]
       public async Task None(IDialogContext context, LuisResult result)
       {
           await context.PostAsync("I'm sorry. I didn't understand you.");
   
           context.Wait(MessageReceived);
       }
   
       [LuisIntent("BookAFlight")]
       public async Task BookAFlight(IDialogContext context, LuisResult result)
       {
           var form = new BookFlightForm();
          // var entities = new List<EntityRecommendation>(result.Entities);
   
           var locations = result.Entities.Where(e => e.Type.Equals("builtin.geography") || e.Type.Equals("builtin.geography.city")).OrderBy(e => e.StartIndex);
   
           if (locations.Any())
           {
               form.LocationFrom = locations.First().Name;
   
               if (locations.Count() == 2)
               {
                   form.LocationTo = locations.Skip(1).First().Name;
               }
           }
   
           var date = result.Entities.FirstOrDefault(e => e.Type == "builtin.datetime.date");
           if (date != null) form.DepartureDate = DateTime.Parse(date.Name);
   
           var formDialog = new FormDialog<BookFlightForm>(form, BuildForm, FormOptions.PromptInStart);
   
           context.Call(formDialog, OnComplete);
       }
   
       private async Task OnComplete(IDialogContext context, IAwaitable<BookFlightForm> result)
       {
           BookFlightForm booking;
           try
           {
               booking = await result;
           }
           catch (OperationCanceledException)
           {
               await context.PostAsync("Ok, see you later.");
               return;
           }
   
           if (booking != null)
           {
               var service = new SkyScannerService();
               var possibilities = await service.Search(booking);
   
               await context.PostAsync(possibilities);
           }
           else
           {
               await context.PostAsync("Form returned empty response!");
           }
   
           context.Wait(MessageReceived);
       }
   }
   

如何修复异常以及如何读取实体的值？

再次感谢!

这是因为您没有通过 using LuisResult = Bots.Results.LuisResult; 使用内置的 LuisResult 类。将其替换为 using Microsoft.Bot.Builder.Luis.Models;。
