我使用这篇文章Link中的解决方案为我的应用程序拼接了一个错误处理。我遇到的问题是应用程序仍在路由到默认错误页面。当我断点代码时，代码一直到 Global.asax，但是当应该加载视图自定义错误页面时，它会从解决方案加载默认错误页面。我试图删除默认错误页面，然后我从 IIS 获得黄色错误页面。不知疲倦地在网上搜索，但没有结果。感谢所有的帮助。如果您认为我可以更好地调整问题或标题，我愿意接受建议。
错误控制器：
public class ErrorController : Controller
{
public ActionResult PageNotFound(Exception ex)
{
Response.StatusCode = 404;
return View("Error", ex);
}
public ActionResult ServerError(Exception ex)
{
Response.StatusCode = 500;
return View("Error", ex);
}
public ActionResult UnauthorisedRequest(Exception ex)
{
Response.StatusCode = 403;
return View("Error", ex);
}
//Any other errors you want to specifically handle here.
public ActionResult CatchAllUrls()
{
//throwing an exception here pushes the error through the Application_Error method for centralised handling/logging
throw new HttpException(404, "The requested url " + Request.Url.ToString() + " was not found");
}
}
Global.asax.cs 中的代码：
protected void Application_Error(object sender, EventArgs e)
{
Exception exception = Server.GetLastError();
//Error logging omitted
HttpException httpException = exception as HttpException;
RouteData routeData = new RouteData();
IController errorController = new Controllers.ErrorController();
routeData.Values.Add("controller", "Error");
routeData.Values.Add("area", "");
routeData.Values.Add("ex", exception);
if (httpException != null)
{
//this is a basic example of how you can choose to handle your errors based on http status codes.
switch (httpException.GetHttpCode())
{
case 404:
Response.Clear();
// page not found
routeData.Values.Add("action", "PageNotFound");
Server.ClearError();
// Call the controller with the route
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
break;
case 500:
// server error
routeData.Values.Add("action", "ServerError");
Server.ClearError();
// Call the controller with the route
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
break;
case 403:
// server error
routeData.Values.Add("action", "UnauthorisedRequest");
Server.ClearError();
// Call the controller with the route
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
break;
//add cases for other http errors you want to handle, otherwise HTTP500 will be returned as the default.
default:
// server error
routeData.Values.Add("action", "ServerError");
Server.ClearError();
// Call the controller with the route
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
break;
}
}
//All other exceptions should result in a 500 error as they are issues with unhandled exceptions in the code
else
{
routeData.Values.Add("action", "ServerError");
Server.ClearError();
// Call the controller with the route
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
}
}
路由配置.cs
routes.MapRoute("CatchAllUrls", "{*url}", new {controller = "Error", action = "CatchAllUrls"});
捕获块：
throw new HttpException(404, "Unable to write to list" + ", " + e.InnerException);
