web.config
关闭 system.web 中的自定义错误
<system.web>
<customErrors mode="Off" />
</system.web>
在 system.webServer 中配置 http 错误
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Auto">
<clear />
<error statusCode="404" responseMode="ExecuteURL" path="/NotFound" />
<error statusCode="500" responseMode="ExecuteURL" path="/Error" />
</httpErrors>
</system.webServer>
创建简单的错误控制器来处理这些请求ErrorContoller.cs
[AllowAnonymous]
public class ErrorController : Controller {
// GET: Error
public ActionResult NotFound() {
var statusCode = (int)System.Net.HttpStatusCode.NotFound;
Response.StatusCode = statusCode;
Response.TrySkipIisCustomErrors = true;
HttpContext.Response.StatusCode = statusCode;
HttpContext.Response.TrySkipIisCustomErrors = true;
return View();
}
public ActionResult Error() {
Response.StatusCode = (int)System.Net.HttpStatusCode.InternalServerError;
Response.TrySkipIisCustomErrors = true;
return View();
}
}
配置路由RouteConfig.cs
public static void RegisterRoutes(RouteCollection routes) {
//...other routes
routes.MapRoute(
name: "404-NotFound",
url: "NotFound",
defaults: new { controller = "Error", action = "NotFound" }
);
routes.MapRoute(
name: "500-Error",
url: "Error",
defaults: new { controller = "Error", action = "Error" }
);
//..other routes
//I also put a catch all mapping as last route
//Catch All InValid (NotFound) Routes
routes.MapRoute(
name: "NotFound",
url: "{*url}",
defaults: new { controller = "Error", action = "NotFound" }
);
}
最后确保您有控制器操作的视图
Views/Shared/NotFound.cshtml
Views/Shared/Error.cshtml
如果您想要处理任何其他错误,您可以按照该模式并根据需要添加。这将避免重定向并保持引发的原始 http 错误状态。
