我有一个问题,因为HTTP错误404.0 – 未找到.我打开了
<customErrors mode="On" defaultRedirect="~/Error/General">
<error statusCode="404" redirect="~/Error/HttpError404" />
<error statusCode="500" redirect="~/Error/HttpError500" />
</customErrors>
在Web.Config中.但问题仍然存在.我也试过这个解决方案(但它永远不会到达方法)：
protected void Application_Error()
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
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"] = "HttpError404";
break;
case 404:
routeData.Values["action"] = "HttpError404";
break;
}
}
IController errorsController = new ErrorController();
var rc = new RequestContext(new HttpContextWrapper(Context),routeData);
errorsController.Execute(rc);
}
这是控制器：
public class ErrorController : Controller
{
public ActionResult HttpError404(string error)
{
ViewData["Title"] = "Sorry,an error occurred while processing your request. (404)";
ViewData["Description"] = error;
return View("Index");
}
public ActionResult HttpError500(string error)
{
ViewData["Title"] = "Sorry,an error occurred while processing your request. (500)";
ViewData["Description"] = error;
return View("Index");
}
public ActionResult General(string error)
{
ViewData["Title"] = "Sorry,an error occurred while processing your request.";
ViewData["Description"] = error;
return this.View();
}
解决方法
好的,我找到了一个解决方案,感谢@ alistair-findlay和
this website.
这就是web.config现在的样子：
这就是web.config现在的样子：
<system.web>
<customErrors mode="On" defaultRedirect="~/Error/General" redirectMode="ResponseRewrite">
</customErrors>
</system.web>
<system.webServer>
<httpErrors errorMode="Detailed" defaultResponseMode="Redirect">
<clear/>
<error statusCode="404" path="/Error/HttpError404"/>
</httpErrors>
</system.webServer
这是Global.asax.cs：
protected void Application_Error()
{
if (Context.IsCustomErrorEnabled)
ShowCustomErrorPage(Server.GetLastError());
}
private void ShowCustomErrorPage(Exception exception)
{
var httpException = exception as HttpException ?? new HttpException(500,"Internal Server Error",exception);
Response.Clear();
var routeData = new RouteData();
routeData.Values.Add("controller","Error");
routeData.Values.Add("fromAppErrorEvent",true);
switch (httpException.GetHttpCode())
{
case 403:
routeData.Values.Add("action","HttpError403");
break;
case 404:
routeData.Values.Add("action","HttpError404");
break;
case 500:
routeData.Values.Add("action","HttpError500");
break;
default:
routeData.Values.Add("action","GeneralError");
routeData.Values.Add("httpStatusCode",httpException.GetHttpCode());
break;
}
Server.ClearError();
IController controller = new ErrorController();
controller.Execute(new RequestContext(new HttpContextWrapper(Context),routeData));
}
最后：
public class ErrorController : Controller
{
public ActionResult HttpError403(string error)
{
ViewBag.Description = error;
return this.View();
}
