我想为500、404和403显示一个自定义错误页面。以下是我所做的:
Enabled custom errors in the web.config as follows:
<customErrors mode="On"
defaultRedirect="~/Views/Shared/Error.cshtml">
<error statusCode="403"
redirect="~/Views/Shared/UnauthorizedAccess.cshtml" />
<error statusCode="404"
redirect="~/Views/Shared/FileNotFound.cshtml" />
</customErrors>
Registered HandleErrorAttribute as a global action filter in the FilterConfig class as follows:
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new CustomHandleErrorAttribute());
filters.Add(new AuthorizeAttribute());
}
Created a custom error page for each of the above messages. The default one for 500 was already available out of the box.
Declared in each custom error page view that the model for the page is System.Web.Mvc.HandleErrorInfo
对于500,它显示自定义错误页面。对其他人来说,则不然。
我是不是遗漏了什么?
当我阅读HandleErrorAttribute类的OnException方法中的代码时,它看起来并不是显示自定义错误的全部,而且它只处理500个。
我必须做什么来处理其他错误?
这是我的解决方案。使用[ExportModelStateToTempData] / [ImportModelStateFromTempData]在我看来是不舒服的。

我做了一些比其他解决方案需要更少的编码。
首先,在我的网里。配置,我有以下:
<customErrors mode="On" defaultRedirect="~/ErrorPage/Oops">
<error redirect="~/ErrorPage/Oops/404" statusCode="404" />
<error redirect="~/ErrorPage/Oops/500" statusCode="500" />
</customErrors>
控制器(/Controllers/ErrorPageController.cs)包含以下内容:
public class ErrorPageController : Controller
{
public ActionResult Oops(int id)
{
Response.StatusCode = id;
return View();
}
}
最后,视图包含以下内容(为了简单起见,删除了内容,但它可以包含:
@{ ViewBag.Title = "Oops! Error Encountered"; }
<section id="Page">
<div class="col-xs-12 well">
<table cellspacing="5" cellpadding="3" style="background-color:#fff;width:100%;" class="table-responsive">

就是这么简单。它可以很容易地扩展,以提供更详细的错误信息,但ELMAH为我处理,statusCode和statusDescription是我通常需要的。
看来我来晚了,但你最好也看看这个。
在系统中。web用于缓存应用程序中的异常,例如返回HttpNotFound()
<system.web>
<customErrors mode="RemoteOnly">
<error statusCode="404" redirect="/page-not-found" />
<error statusCode="500" redirect="/internal-server-error" />
</customErrors>
</system.web>
在系统中。webServer用于捕获IIS捕获的错误,而这些错误没有进入asp.net框架
<system.webServer>
<httpErrors errorMode="DetailedLocalOnly">
<remove statusCode="404"/>
<error statusCode="404" path="/page-not-found" responseMode="Redirect"/>
<remove statusCode="500"/>
<error statusCode="500" path="/internal-server-error" responseMode="Redirect"/>
</system.webServer>
在最后一个例子中,如果你担心客户端响应,那么将responseMode="Redirect"更改为responseMode="File"并提供一个静态html文件,因为这个例子将显示一个响应代码为200的友好页面。
这是我的解决方案。使用[ExportModelStateToTempData] / [ImportModelStateFromTempData]在我看来是不舒服的。
