Question

我已经在我的机器人应用程序中实现了依赖注入。

LuisDialog.cs

CarInventory

LuisDialog.cs-销售意向

[LuisModel("xxx", "xxx")]
[Serializable]
public class LUISDialog : LuisDialog<object>
{
    private LuisDialog<object> _luisDialog;
    private ISalesDialog _salesDialog;

    public LUISDialog(LuisDialog<object> luisDialog, ISalesDialog salesDialog)
    {
        _luisDialog = luisDialog;
        _salesDialog = salesDialog;
    }
 }

MessagesController.cs

    [LuisIntent("Sales")]
    public async Task Sales(IDialogContext context, LuisResult result)
    {
        // Pass request to service for answer
        await context.PostAsync(_salesDialog.GetAnswer(result.Query));            
    }

我的问题： 感觉像是DI破坏了bot框架的流程。具体来说，是一种用于验证需要路由到什么意图的机制。

我的应用程序可以通过模拟器正常加载。但是，在键入特定于销售意图的条目时，它击中了我的LUISDialog类中的构造函数（按预期方式）落入WebAPIconfig.cs中，并在JsonConvert.DefaultSettings调用上失败：

[BotAuthentication]
public class MessagesController : ApiController
{
    private LuisDialog<object> _luisDialog;
    private ISalesDialog _salesDialog;

    public MessagesController(LuisDialog<object> luisDialog, ISalesDialog salesDialog)
    {
        _luisDialog = luisDialog;
        _salesDialog = salesDialog;       
    }

    /// <summary>
    /// POST: api/Messages
    /// Receive a message from a user and reply to it
    /// </summary>
    public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
    {   
        var container = UWServiceInfrastructure.Infrastructure.EngineContext.Current.ContainerManager.Container;

        if (activity.Type == ActivityTypes.Message)
        {
            await Conversation.SendAsync(activity, () => new LUISDialog(_luisDialog, _salesDialog));
        }
        else
        {
            HandleSystemMessage(activity);
        }

        var response = Request.CreateResponse(HttpStatusCode.OK);

        return response;
    }

没有错误信息。我刚收到一个500的响应码。当我注释掉LUISDialog构造函数中的注入片段时，正确选择了意图。不知道我在这里可能会错过什么。

BotFramework中的Autofac-中断LUIS流吗？
