为了避免这种情况,并用正确的HttpCode返回自定义视图:
在你的web.config,删除错误的元素和设置:
<system.webServer>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
在您的Global.asax,使用此呈现的自定义asp.net MVC视图:
protected void Application_Error(object sender, EventArgs e)
{
var ex = HttpContext.Current.Server.GetLastError();
if (ex == null)
return;
while (!(ex is HttpException))
ex = ex.GetBaseException();
var errorController = new ErrorsController();
HttpContext.Current.Response.Clear();
var httpException = (HttpException)ex;
var httpErrorCode = httpException.GetHttpCode();
HttpContext.Current.Response.Write(errorController.GetErrorGeneratedView(httpErrorCode, new HttpContextWrapper(HttpContext.Current)));
HttpContext.Current.Response.End();
}
在您的自定义ErrorsController,添加此生成从asp.net的MVC查看HTML视图:
public string GetErrorGeneratedView(int httpErrorCode, HttpContextBase httpContextWrapper)
{
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "Default";
httpContextWrapper.Response.StatusCode = httpErrorCode;
var model = httpErrorCode;
using (var sw = new StringWriter())
{
ControllerContext = new ControllerContext(httpContextWrapper, routeData, this);
var viewEngineResult = ViewEngines.Engines.FindPartialView(ControllerContext, "Default");
ViewData.Model = model;
var viewContext = new ViewContext(ControllerContext, viewEngineResult.View, ViewData, TempData, sw);
viewEngineResult.View.Render(viewContext, sw);
return sw.ToString();
}
}
您应该小心301,因为有些客户端会更新他们存储的链接。这可能意味着导致404(可能在手动发布期间)的临时故障将永久断开它们的链接。来自rfc2616'所请求的资源已被分配一个新的永久URI,并且任何将来对这个资源的引用都应该使用返回的URI之一。在可能的情况下,具有链接编辑功能的客户端应自动将对Request-URI的引用重新链接到服务器返回的一个或多个新引用。除非另有说明,否则此响应是可缓存的 – Basic 2013-03-08 21:09:14
