asp.net-mvc-3 - 执行子请求时出错

Question

在我的 MVC3 应用程序中，当我尝试处理超出最大请求的错误时出现上述错误。

我在应用程序级别处理异常。我正在尝试重定向到位于 View 的共享文件夹中的错误页面。

如果请求大小超过限制，我将使用下面的代码重定向到错误页面。

 this.Server.ClearError();
 this.Server.Transfer("~/Views/Shared/NotAuthorised.cshtml");

这是我收到的错误。

Error executing child request for /SiteName/Views/Shared/NotAuthorised.cshtml

Answer 1

根据 Microsoft 文档 (Error Executing Child Request" Error Message When You Use Server.Transfer or Server.Execute in ASP.NET Page)，您不能在应用程序级错误后使用 Server.Transfer。

Microsoft Internet Information Services (IIS) dispatches the Server.Transfer or the Server.Execute request to the appropriate Internet Server Application Programming Interface (ISAPI) extension based on the extension of the requesting file. For example, a request for an .aspx page is dispatched to the Aspnet_isapi.dll ISAPI extension.

After the request is dispatched to appropriate ISAPI extension, the ISAPI extension cannot call another ISAPI extension. You receive the error message that is listed in the "Symptoms" section because the Aspnet_isapi.dll file, which handles requests to ASP.NET pages, cannot forward the request to the Asp.dll file, which handles requests to ASP pages.

但是您可以像这样使用 Response.Redirect(path):

Response.Redirect("Home/About");
