有没有一种方法可以在ASP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，我使用过Microsoft的Scott Hanselman编写的一些代码.但是现在我正在使用MVC5，并且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MVC5中采用的路由，以便知道为什么会看到类似这样的消息:

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

我知道对OP来说已经很晚了，但是对于其他尝试调试404错误的人来说，我找到了一种拦截路由结果并查看其原因的方法找不到资源.

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线信息.我已经在MVC5上进行了测试.

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

我最初是在Paul Evans的另一个答案中碰到此方法的，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
