我跟隨了this post並創建了全局錯誤處理程序。我添加了自己處理404錯誤。但是,當我在本地測試時它工作正常,但一旦部署到Web服務器,我的自定義消息不再顯示。相反,默認醜陋的一個出現。爲什麼我的自定義404錯誤處理程序在部署到Web服務器後不起作用
在遠程調試中,我可以跟蹤執行情況,它確實得到我自定義的404錯誤操作,但不知何故,IIS在某個時候接管了。
在我的Global.asax.cs,我有:
protected void Application_Error()
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Error";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;
Response.StatusCode = 500;
if (httpException != null)
{
Response.StatusCode = httpException.GetHttpCode();
switch (Response.StatusCode)
{
case 403:
routeData.Values["action"] = "Http403";
break;
case 404:
routeData.Values["action"] = "Http404";
break;
}
}
IController errorController = new ErrorController();
var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
errorController.Execute(rc);
}
然後在我的ErrorHandler.cs,我有:
public ActionResult General(Exception exception)
{
// log error
return Content("General error", "text/html");
}
public ActionResult Http403(Exception exception)
{
return Content("Forbidden", "text/plain");
}
public ActionResult Http404(Exception exception)
{
return Content("Page not found.", "text/plain"); // this displays when tested locally, but not after deployed to web server.
}
}
