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。

一些重大更改是 reported here，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：

当我向控制器发送消息语句时，代码抛出 InvalidIntentHandlerException。

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 LuisResult class。将其替换为 using Microsoft.Bot.Builder.Luis.Models;.
