asp.net MVC3上的自定义错误页面我正在开发一个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 modeif (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, we will display static HTML error page
Log.Logger.Fatal("failed to display error page, fallback to HTML error: ", e);
Response.TransmitFile("~/error.html");
}}}

这是我如何处理自定义错误的示例。我定义了一个ErrorsController
处理不同HTTP错误的动作:
public class ErrorsController : Controller{ public ActionResult General(Exception exception) { return Content("General failure", "text/plain"); } public ActionResult Http404() { return Content("Not found", "text/plain"); } public ActionResult Http403() { return Content("Forbidden", "text/plain"); }}
然后我订阅了Application_Error
in Global.asax
并调用了这个控制器:
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"] = "Http403"; break; case 404: routeData.Values["action"] = "Http404"; break; } } IController errorsController = new ErrorsController(); var rc = new RequestContext(new HttpContextWrapper(Context), routeData); errorsController.Execute(rc);}

您也可以在Web.Config文件中执行此操作。这是一个适用于IIS 7.5的示例。
<system.webServer> <httpErrors errorMode="DetailedLocalOnly" defaultResponseMode="File"> <remove statusCode="502" subStatusCode="-1" /> <remove statusCode="501" subStatusCode="-1" /> <remove statusCode="412" subStatusCode="-1" /> <remove statusCode="406" subStatusCode="-1" /> <remove statusCode="405" subStatusCode="-1" /> <remove statusCode="404" subStatusCode="-1" /> <remove statusCode="403" subStatusCode="-1" /> <remove statusCode="401" subStatusCode="-1" /> <remove statusCode="500" subStatusCode="-1" /> <error statusCode="500" path="/notfound.html" responseMode="ExecuteURL" /> <error statusCode="401" prefixLanguageFilePath="" path="/500.html" responseMode="ExecuteURL" /> <error statusCode="403" prefixLanguageFilePath="" path="/403.html" responseMode="ExecuteURL" /> <error statusCode="404" prefixLanguageFilePath="" path="/404.html" responseMode="ExecuteURL" /> <error statusCode="405" prefixLanguageFilePath="" path="/405.html" responseMode="ExecuteURL" /> <error statusCode="406" prefixLanguageFilePath="" path="/406.html" responseMode="ExecuteURL" /> <error statusCode="412" prefixLanguageFilePath="" path="/412.html" responseMode="ExecuteURL" /> <error statusCode="501" prefixLanguageFilePath="" path="/501.html" responseMode="ExecuteURL" /> <error statusCode="502" prefixLanguageFilePath="" path="/genericerror.html" responseMode="ExecuteURL" /> </httpErrors></system.webServer>
