asp.net-mvc – 在MVC3中的错误 – 请求永远不会超时 在同一项目中的aspx页面工作良好

我在我们的生产网站上看到这个，以及一个小的测试网站，我只是为了测试这个…

基本上，似乎由mvc处理的请求永远不会超时。我在我的web.config中设置了一个executionTimeout并关闭调试模式。然后我添加了一个无限循环的thread.sleeps到一个常规aspx页面和一个mvc页面(循环是在mvc页面的控制器)。 aspx页面可靠超时(HttpException(0x80004005)：请求超时。)，但是mvc页面只是旋转永远没有超时。

有没有单独的设置mvc(我看过，但没有找到它们)？ Do mvc请求默认不超时？

任何帮助，这将不胜感激。我会很高兴地发电子邮件发送我的小测试网站，如果它会帮助任何人。

编辑：我使用MVC3。

我的web.config的内容：

解决方法

此方法在WrappedAsyncResult类中，MvcHandler类通过BeginProcessRequest使用该类：

public static IAsyncResult BeginSynchronous<TResult>(AsyncCallback callback,object state,Func<TResult> func,object tag)
{
    BeginInvokeDelegate beginDelegate = delegate (AsyncCallback asyncCallback,object asyncState) {
        SimpleAsyncResult result = new SimpleAsyncResult(asyncState);
        result.MarkCompleted(true,asyncCallback);
        return result;
    };
    EndInvokeDelegate<TResult> endDelegate = _ => func();
    WrappedAsyncResult<TResult> result = new WrappedAsyncResult<TResult>(beginDelegate,endDelegate,tag);
    result.Begin(callback,state,-1);
    return result;
}

其中“Begin”是：

public void Begin(AsyncCallback callback,int timeout)
{
    bool completedSynchronously;
    this._originalCallback = callback;
    lock (this._beginDelegateLockObj)
    {
        this._innerAsyncResult = this._beginDelegate(new AsyncCallback(this.HandleAsynchronousCompletion),state);
        completedSynchronously = this._innerAsyncResult.CompletedSynchronously;
        if (!completedSynchronously && (timeout > -1))
        {
            this.CreateTimer(timeout);
        }
    }
    if (completedSynchronously && (callback != null))
    {
        callback(this);
    }
}

编辑：提出了一个ham-handed的方式强制MVC控制器的行动“超时”，虽然机制有点粗暴：

public class TimeoutController : Controller
{
    private bool _isExecuting = false;
    private int _controllerTimeout = 5000;
    private Thread _executingThread;
    private readonly object _syncRoot = new object();

    protected override void ExecuteCore()
    {
        _executingThread = Thread.CurrentThread;
        ThreadPool.QueueUserWorkItem(o =>
            {
                Thread.Sleep(_controllerTimeout);
                if (_isExecuting)
                {
                    _executingThread.Abort();
                }
            });
        base.ExecuteCore();
    }

    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        _isExecuting = true;
        base.OnActionExecuting(filterContext);
    }

    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        _isExecuting = false;                
        base.OnActionExecuted(filterContext);
    }

    public int ControllerTimeout
    {
        get
        {
            int retVal;
            lock(_syncRoot)
            {
                retVal = _controllerTimeout;
            }
            return retVal;
        }
        set
        {
            lock(_syncRoot)
            {
                _controllerTimeout = value;                    
            }
        }
    }
}
