出现 404 错误。跳过 404 页面并转到 .aspxerrorpath= page.aspx和写作您正在查找的资源已被删除、更名或暂时不可用。

我想显示我自定义的 404、500 错误页面。怎么了

简而言之，在生产中可以完全摆脱“system.web -> customErrors”部分，该部分几乎是出于兼容性目的而保留的(查看 What is the difference between customErrors and httpErrors? 线程以了解更多信息)，以及您在哪里还指定重定向。然后，仅在“system.webServer -> httpErrors”部分中指定必要的重定向和自定义错误页面。确保这些 HTML 文件存在于 Web 服务器上，并且可通过相对路径访问(或者这些页面存在于同一 Web 服务器上的父 Web 应用程序之一内，以便继承这些“错误”设置)。

解决方案资源管理器:

~/YourWebApp

• ...

• not_found.html

• Web.config

Web.config(针对 404 状态代码错误):

<!--Dev: For Visual Studio Mode-->
<system.web>
  <customErrors mode="On">
    <error statusCode="404" redirect="~/not_found.html" />
  </customErrors>
</system.web>


<!--Prod: For IIS Mode-->
<system.webServer>
  <httpErrors errorMode="Custom">
    <!--<error statusCode="404" path="C:\Inetpub\vhosts\domain.win2012.tld\error_docs\not_found.html" />-->
    <error statusCode="404" path="~/not_found.html" responseMode="Redirect" />
  </httpErrors>
</system.webServer>
