有没有办法可以在 ASP.NET 中调试路由.MVC5? [英] Is there a way I can debug a route in ASP. MVC5?

问题描述

过去我使用了一些我认为是微软的 Scott Hanselman 的代码.但是现在我使用的是 MVC5，我认为该代码不再有效.

In the past I have used some code by I think Scott Hanselman of Microsoft. However now I am using MVC5 and I don't think that code is valid any more.

有没有一种方法可以跟踪在 MVC5 中采用的路由，以便我知道为什么我会看到如下消息:

Is there a way I can trace routes taken in MVC5 so that I can know why I see messages like:

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

推荐答案

我知道现在对于 OP 来说已经晚了，但是对于其他任何试图调试 404 错误的人，我已经找到了一种拦截路由结果的方法，看看为什么会这样找不到资源.

I know it is late for the OP but for anyone else trying to debug 404 errors I've found a way to intercept the route result and see why it is failing to find the resource.

在 Global.asax.cs 中像这样覆盖 Init:

In Global.asax.cs override Init like this:

    public override void Init()
    {
        base.Init();
        this.AcquireRequestState += showRouteValues;
    }

    protected void showRouteValues(object sender, EventArgs e)
    {
        var context = HttpContext.Current;
        if (context == null)
            return;
        var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(context));
    }

routeData 变量将保存正在解释的路由信息​​.我已经在 MVC5 上测试过了.

The routeData variable will hold the route info as it is being interpreted. I've tested this on MVC5.

我最初在 Paul Evans 的另一个答案中遇到了这种方法，这是链接(感谢@porcus 找到它):stackoverflow.com/a/25466524

I originally bumped into this method in another answer by Paul Evans, this is the link (thanks to @porcus for finding it): stackoverflow.com/a/25466524
