传入ASP.NET MVC的价值定义错误页

问题描述

我要一个标识符传递到ASP.NET MVC自定义错误页。

I want to pass an identifier to a custom error page in ASP.NET MVC.

我有web.config中设置重定向到一个错误页面时，有一个状态500错误。我不知道如何从应用code抛出异常传递一个错误的ID（还设置500 HTTP状态）返回到所配置的错误页面。

I have the web.config set up to redirect to an error page when there is an status 500 error. I don't know how to pass an error id from the application code that throws the exception (also sets HTTP Status of 500) back to the error page that is configured.

如果我只是用状态200并返回从控制器的错误方法的示意图，并在那里做了所有的逻辑，但其状态code必须是500，所以这不是一个可接受的解决方案，这很容易。

It's easy if I just used Status 200 and returned a view from the Error method of the controller and did all the logic in there, however the Status code must be 500, so that's not an acceptable solution.

我也没有和这不会使用会话。我想使用的查询字符串或查看数据。

I also do not and will not use session for this. I'd like to use query string or view data.

不重复。这是关于错误处理（状态code 500）和异常。 404大约是找不到页面

推荐答案

我不知道定制信息的更好的方式来错误的web.config配置的页面。这是当我需要一个错误重定向我通常做的：

I don't know a better way to customized information to error page configured in web.config. This is what I normally do when i need an error redirection:

我将创建一个错误处理行为过滤器：

I'll create an error handler action filter:

public class MyErrorHandler: HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.Exception != null)
        {
            filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
            filterContext.ExceptionHandled = true;
            filterContext.Result = new RedirectResult("/error?error_id=123456", true);
            return;
        }
        base.OnException(filterContext);
    }
}

中的异常过滤器，你可以尝试处理目前存在的误差不同的错误标识，或任何你preFER改变例外。

Within the Exception filter, you may try to handle differnet error with different error id, or whatever you prefer to alter the exception.

然后应用到它的控制器或CONTROLER类：

Then apply it onto controller or controler class:

[MyErrorHandler]
public class HomeController : Controller
{
    ....
}

，你会得到一个HTTP状态500和将被重定向到：

And you will get a Http status 500 and will be redirected to:

http://<host>/error?error_id=123456
