将 MapPageRoute 添加到 asp.net mvc 项目后，站点停止进入 Home Controller [英] After add MapPageRoute to an asp.net mvc project, the site stops to enter in Home Controller

问题描述

我正在尝试在我的 asp.net mvc 项目中路由一个 .aspx(webforms 页面).我在 global.asax 中注册页面:

I'm trying to route a .aspx (webforms page) in my asp.net mvc project. I register the page in global.asax:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapPageRoute("Tickets", "Reports/Tickets", "~/WebForms/Reports/Tickets.aspx");
routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional });

问题是，在我添加第二行之后，站点停止进入我的主控制器(索引操作)并重定向到:http://localhost:37538/Reports/Tickets?action=Index&controller=Login%22 总是我运行项目.

The problem is, after i add the second line, the site stops to enter in my Home Controller (Index Action) and is redirecting to: http://localhost:37538/Reports/Tickets?action=Index&controller=Login%22 always that i run the project.

项目详情:

• Asp.Net MVC 3
• 表单验证
• .Net 4.0

Obs:要重现此错误，请在 /WebForms/Reports 文件夹中创建 Tickets webforms 页面后，创建一个新的 asp.net mvc 项目作为 Internet 应用程序，并注册新路线.运行项目(可能您已登录)，现在注销，您将被重定向到 http://localhost:35874/Reports/Tickets?action=LogOff&controller=Account，为什么?

Obs: to reproduce this error, create a new asp.net mvc project as internet app, after create the Tickets webforms page inside a /WebForms/Reports folder, and register the new route. Run the project (probably you're logged), so now logoff and you will be redirected to http://localhost:35874/Reports/Tickets?action=LogOff&controller=Account, so why?

推荐答案

解决了！ 所以，我们需要在 webforms 路由中添加一个路由约束，以确保它只捕获传入的路由，而不是传出路由生成.

Solved! So, we need to add a route contraint to the webforms route to ensure that it only catches on incoming routes, not outgoing route generation.

将以下类添加到您的项目中(在新文件中或 global.asax.cs 的底部):

Add the following class to your project (either in a new file or the bottom of global.asax.cs):

public class MyCustomConstraint : IRouteConstraint{
    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection){
        return routeDirection == RouteDirection.IncomingRequest;
    }
}

然后将Tickets路由更改为以下:

Then change the Tickets route to the following:

routes.MapPageRoute(
    "Tickets",
    "Reports/Tickets",
    "~/WebForms/Reports/Tickets.aspx",
    true, null, 
    new RouteValueDictionary { { "outgoing", new MyCustomConstraint() } }
);
