问题描述

我在 ASP.NET 网站上设置了自定义错误页面.

I have custom error pages setup on an ASP.NET website.

有一个错误没有显示自定义错误页面，而只是显示了通常的黄色 ASP.NET 错误页面.如果打开自定义错误，则会显示/应用程序中的服务器错误"/运行时错误"，但如果关闭自定义错误，则会显示viewstate mac 验证失败"错误.

There is one error that is not showing a custom error page, and just showing the usual yellow ASP.NET error page. If custom errors are turned on it shows "Server error in / application" / "Runtime error", but if custom errors are off it shows "validation of viewstate mac failed" error.

我的 web.config 的相关部分是:

The relevant parts of my web.config are:

<system.web>
  <compilation debug="false" targetFramework="4.0" />
    <customErrors mode="On" redirectMode="ResponseRewrite">
      <error statusCode="404" redirect="/404.aspx" />
      <error statusCode="500" redirect="/500.aspx" />
    </customErrors>

<system.webServer>
  <httpErrors errorMode="DetailedLocalOnly" />

要捕获此错误，我是否必须使用不同的状态代码或子状态代码，或者还有其他什么?

To trap for this error do I have to use a different status code or substatuscode or is there something else?

注意.服务器 2008 R2，IIS 7.

NB. Server 2008 R2, IIS 7.

推荐答案

经过进一步研究，我发现这意味着 IIS 正在显示错误，而不是 ASP.NET.

After further research I see that this means that IIS is displaying the error rather than ASP.NET.

我更改了 web.config 的 system.webServer 部分，因此 IIS 也可以使用自定义错误页面，从而解决了问题.

I changed the system.webServer part of my web.config so IIS can also use the custom error page and that has solved the problem.

<system.webServer>
  <httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="500" subStatusCode="-1" />
    <error statusCode="500" subStatusCode="-1" responseMode="ExecuteURL" path="/500.aspx" />
  </httpErrors>
