Question

我按照tutorial进行了操作，但我仍然收到了启用错误的ASP.NET屏幕，或者显示自定义错误页面。

我已经注册了HandleErrorAttribute并在web.config中添加了<customErrors mode="On" />。该属性直接位于Controller类签名之前的行上。

我还缺少什么吗？

修改

我按照你的建议从类中删除了属性，这就是结果。没有什么特别的事我想不到。

的web.config

</appSettings>
  <system.web>
    <customErrors mode="On" />
    <compilation debug="true" targetFramework="4.0">
      <assemblies>

Global.asax中

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
        }

        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
            );

        }

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RegisterGlobalFilters(GlobalFilters.Filters);
            RegisterRoutes(RouteTable.Routes);

错误*

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.

Details: To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly"/>
    </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="On" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

Answer 1

如果您希望查看自定义错误页面（您自己设计的页面），那么您需要实际创建页面并在customErrors元素中引用;

<customErrors defaultRedirect="GenericError.htm" mode="On" />

在上面的示例中，您将在Web应用程序中创建GernericError.htm页面。如果出现错误，将显示此信息。

如果您想查看有关抛出的实际异常的详细信息，则需要将模式设置为mode="Off"或mode="RemoteOnly"

另外，请确保您在IIS中为您的应用程序运行正确版本的asp.net（即asp.net 4.0），否则您的web.config文件可能无法正确解析，从而导致此页面。
