ASP.NET MVC 5中的自定义错误页面 [英] Custom error pages in ASP.NET MVC 5

问题描述

我想将自定义错误页面添加到我的项目中. 我发现关于我的问题的帖子，我尝试实现它.

I want to add custom error pages to my project. I found this post about my problem and i try to implement it.

所以:

• 我添加404.cshtml，404.html，500.cshtml和500.html页面
• 在添加的cshtml文件中设置响应状态代码
• 评论将HandleErrorAttribute添加到全局过滤器
• 更新我的web.config文件

• i add 404.cshtml, 404.html, 500.cshtml and 500.html pages
• set response status code in added cshtml files
• comment adding HandleErrorAttribute to global filters
• update my web.config file

但是现在当我尝试通过路径http://localhost:120/foo/bar我的应用程序位于http://localhost:120的位置时，我进入了下一页:

But now when i try to go by path http://localhost:120/foo/bar where my app is on http://localhost:120 i get next page :

"/"应用程序中的服务器错误.

Server Error in '/' Application.

运行时错误

描述:处理您的请求时发生异常.此外，在执行第一个异常的自定义错误页面时发生了另一个异常.该请求已被终止.

Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.

我设置了<customErrors mode="Off"以查看是什么问题.这是-The resource cannot be found.这是合乎逻辑的.但是当我设置<customErrors mode="On"时-我再次遇到运行时错误.

I set <customErrors mode="Off" to see what problem is. It was - The resource cannot be found. which is logical. But when i set <customErrors mode="On" - i again get Runtime error.

是什么原因引起的，如何解决?

What can cause it and how to solve it?

我的配置文件:

<system.web>
    <customErrors mode="Off" redirectMode="ResponseRewrite" defaultRedirect="~/500.cshtml">
        <error statusCode="404" redirect="~/404.cshtml"/>
        <error statusCode="500" redirect="~/500.cshtml"/>
    </customErrors>
</system.web>

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="404.html" responseMode="File"/>
        <remove statusCode="500"/>
        <error statusCode="500" path="500.html" responseMode="File"/>
    </httpErrors>
</system.webServer>

IIS 8.5版

IIS version 8.5

推荐答案

您使用的是哪个版本的IIS?如果为7+，则使用<customErrors mode="Off">忽略自定义错误，然后使用<httpErrors>.使用下面的方法将在不更改URL的情况下显示错误页面，而IMO是处理这些问题的首选方法.

What version of IIS are you using? If 7+ then ignore custom errors using <customErrors mode="Off"> and use <httpErrors>. Using the method below the latter will show your error page without changing the URL which IMO is the preferred way of handling these things.

设置一个错误控制器，然后将404和500放在其中，如下所示:

Set up an Error Controller and put your 404 and 500 in there like so:

<httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="404" />
    <remove statusCode="500" />
    <error statusCode="404" path="/error/notfound" responseMode="ExecuteURL" />
    <error statusCode="500" path="/error/servererror" responseMode="ExecuteURL" />
 </httpErrors>

在控制器中:

public class ErrorController : Controller
{
    public ActionResult servererror()
    {
        Response.TrySkipIisCustomErrors = true;
        Response.StatusCode = (int)HttpStatusCode.InternalServerError;
        return View();
    }

    public ActionResult notfound()
    {
        Response.TrySkipIisCustomErrors = true;
        Response.StatusCode = (int)HttpStatusCode.NotFound;
        return View();
    }

}

然后显然可以为所涵盖的每个错误设置相应的视图.

Then obviously set up the corresponding view for each error covered.
