如何处理Botframework SDK3 C#中的超时 [英] How to deal with timeouts in botframework SDK3 C#

问题描述

很抱歉我是一个新手，我有很多问题.

I'm so sorry that I'm a newbie that I have so many questions.

我的机器人状态保存在数据库中.因此它永远不会超时.我使用团队. 但是，如果用户在10分钟内未回复，我想重新开始对话.

My Bot state is save in DB. So it would never timeout. And I use teams. But I want to restart conversation if user don't reply for 10 minutes.

这是我的解决方案. 根据此，我还制作了静态字典，可以帮助我处理每次对话.定时器很容易.并借助示例代码，我确实中断了堆栈.但是，一旦完成，它将回到原始对话.解决这个问题.我根据此

This is my solution. According this, I also made a static dictionary which could help me to handle every conversations' timer easily. And with the help of Sample Code, I did interrupt the stack. But once it's finished, it will be back to the original conversation. To solve this problem. I cleared the state according this

推荐答案

我确定有很多方法可以解决此问题，但这是您可以尝试的一种方法.

I'm sure there are a number of ways to solve this but here is one way you can try.

在您的Global.asax中

In your Global.asax

为您的线程定义此取消令牌来源

Define this cancellation token source for your thread

 CancellationTokenSource _getTokenAsyncCancellation = new CancellationTokenSource();

在Application_Start()代码中，设置带有while循环的Task线程.看起来像这样:

In Application_Start() code setup a Task thread with a while loop. It will look something like this:

Task.Factory.StartNew(async () =>
            {
                while (!_getTokenAsyncCancellation.IsCancellationRequested)
                {
                    try
                    {
                        //Check timespan between last message timestamp vs NOW
                        //if timespan > 9 minutes
                        //   send message 
                    }
                    catch (Exception ex)
                    {
                        Trace.TraceError(ex.Message);
                    }
                    await Task.Delay(TimeSpan.FromMinutes(1), _getTokenAsyncCancellation.Token).ConfigureAwait(false);
                }
            }).ConfigureAwait(false);

此外，添加Application_edn方法以彻底清除问题

Also, add an Application_edn method to sht things down cleanly

protected void Application_End()
        {
            _getTokenAsyncCancellation.Cancel();
        }

现在，您还没有完成.您还需要一些跟踪用户的最后一条消息时间戳.基本上，每次自动程序收到用户的新消息时，您都会设置此时间戳，而while循环中的代码将对此进行检查.

Now, you're not quite done. You will also need somewhat to track the user's last message timestamp. Basically, each time the bot receives a new message from the user yo will set this timestamp and the code in your while loop will check against that.

我希望这会有所帮助，并为您提供一些尝试方法的想法.

I hope this helps and gives you some ideas on what to try.
