我正在开发一个MVC3基础网站,我正在寻找一个处理错误的解决方案,并为每种错误渲染自定义视图.因此,假设我有一个"错误"控制器,其主要操作是"索引"(通用错误页面),并且此控制器将针对用户可能出现的错误(如"Handle500"或"HandleActionNotFound")执行更多操作.
因此,网站上可能发生的每个错误都可能由此"错误"控制器处理(例如:"Controller"或"Action"未找到,500,404,dbException等).
我使用Sitemap文件来定义网站路径(而不是路由).
这个问题已经回答了,这是对Gweebz的回复
我的最终applicaiton_error方法如下:
protected void Application_Error() {
//while my project is running in debug mode
if (HttpContext.Current.IsDebuggingEnabled && WebConfigurationManager.AppSettings["EnableCustomErrorPage"].Equals("false"))
{
Log.Logger.Error("unhandled exception: ", Server.GetLastError());
}
else
{
try
{
var exception = Server.GetLastError();
Log.Logger.Error("unhandled exception: ", exception);
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;
IController errorsController = new ErrorsController();
var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
errorsController.Execute(rc);
}
catch (Exception e)
{
//if Error controller failed for same reason, …我使用下面的代码实现了异常处理.[编辑开始]我不知道它为什么两次调用视图.[已编辑完成]
Basecontroller
public class BaseController : Controller
{
protected override void OnException(ExceptionContext filterContext)
{
if (filterContext.HttpContext.IsCustomErrorEnabled)
{
filterContext.ExceptionHandled = true;
if (filterContext.Exception.GetType() == typeof(ArgumentOutOfRangeException))
{
this.View("OutOfRange").ExecuteResult(this.ControllerContext);
}
else
{
this.View("Error").ExecuteResult(this.ControllerContext);
}
}
base.OnException(filterContext);
}
}
HomeController的
public class HomeController : BaseController
{
public ActionResult Exception2()
{
throw (new ArgumentOutOfRangeException());
}
public ActionResult Exception3()
{
throw (new Exception());
}
}
错误视图(仅限共享文件夹)
@model System.Web.Mvc.HandleErrorInfo
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>Error</title>
</head>
<body>
<h2>
