Question

我在视图中设置了/shared/error.cshtml页面，以显示更友好的错误消息。但是当用户遇到错误时它没有显示。

我的web.config文件有：

<system.web>
<customErrors mode="On" />

我的global.asax.cs有：

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

但我得到的错误信息仍然是基本的

`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".`

我缺少什么？

Answer 1

通过在

下添加以下行来激活Web.config中的自定义错误

<system.web>:

<customErrors mode="On" defaultRedirect="/Error">
  <error redirect="/Error/NotFound" statusCode="404"/>
  <error redirect="/Error/InternalServerError" statusCode="500"/>
</customErrors>

注意：您可以设置mode =“Off”以禁用在开发或调试时可能有用的自定义错误。设置模式=“RemoteOnly”仅激活远程客户端的自定义错误

Answer 2

你应该有一个ErrorController，其中包含一个显示错误视图的操作。该动作应该有以下注释：

[HandleError(View = "Error", ExceptionType = typeof(Exception))]

Answer 3

想出来，当一个错误没有使用基本控制器时，一些动态内容没有被加载，因此错误处理引发了错误

MVC自定义错误未显示
