【问题标题】:ASP.net Server Error in '/' Application“/”应用程序中的 ASP.net 服务器错误
【发布时间】:2012-02-09 15:27:11
【问题描述】:

我的主页上一直有用户收到此错误:

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 remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, 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 "Off".

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

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

我无法在现场或我的开发服务器上重现此错误。但是,在我的 web.config 文件中,我相信我确实正确设置了错误代码:

<customErrors mode="On" defaultRedirect="~/error.aspx" redirectMode="ResponseRewrite">
    <error statusCode="500" redirect="~/error.aspx" />
</customErrors>

网站上的所有其他错误似乎都指向 error.aspx,没有人知道为什么会发生此错误以及如何捕获它?

【问题讨论】:

  • 您应该根据消息在服务器上查看错误的详细信息。一旦你看到实际的错误,你可能会想到它。
  • 您是否尝试过捕获 Global.asax 文件中的错误?

【解决方案1】:

您应该查看您的Application Log in the Event Viewer 以查看实际的错误消息是什么。找到错误消息后 - 您可以确定它没有重定向的原因。

另一个选择(虽然对公共站点很危险)是更改错误处理程序以显示带有堆栈跟踪的实际错误消息,以便您可以解决问题(customErrors mode='Off')。然后,用户可以将实际错误传递给您,而不是上面的通用错误页面。

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