Asp.Net MVC中捕捉错误路由并设置默认Not Found页面。

2017-04-11 15:17 537 查看
在Global中写一个Application_Error捕捉错误路由并重定向到Not Found页面。这里是全局性抓取错误路由，此处还可以写由错误路由导致访问失败的日志记录。

protected void Application_Error(object sender, EventArgs e)
{
var httpContext = ((MvcApplication)sender).Context;
var currentController = "";
var currentAction = "";
var currentRouterData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));

if (currentRouterData != null)
{
if (currentRouterData.Values["controller"] != null && !string.IsNullOrEmpty(currentRouterData.Values["controller"].ToString()))
{
currentController = currentRouterData.Values["controller"].ToString();
}

if (currentRouterData.Values["action"] != null && !string.IsNullOrEmpty(currentRouterData.Values["action"].ToString()))
{
currentAction = currentRouterData.Values["action"].ToString();
}
}

var ex = Server.GetLastError();
//record error log here.

var controller = new ErrorController();
var routeData = new RouteData();
var action = "Index";

if (ex is HttpException)
{
var httpEx = ex as HttpException;

switch (httpEx.GetHttpCode())
{
case  404:
action = "Not Found";
Response.Redirect("/Error/index");
break;
}

httpContext.ClearError();
httpContext.Response.Clear();
httpContext.Response.StatusCode = ex is HttpException ? ((HttpException)ex).GetHttpCode() : 500;
httpContext.Response.TrySkipIisCustomErrors = true;

routeData.Values["controller"] = "Error";
routeData.Values["action"] = action;
}
}


NotFound页面：

@{
Layout = null;
}
