Question

给出一个mvc4，它在路由中有{sitename}参数，如此

routes.MapRoute(
    "Sites", // Route name
    "{sitename}/{controller}/{action}/{id}", // URL with parameters
    new { sitename = "", controller = "Home", action = "Index", id = "" } // Parameter defaults
);

并且除了AccountController和任何其他使用[Authorize]属性的重定向到

之外，一切正常

 ~/Account/Login

而不是

 ~/{sitename}/Account/Login

一致性和美学性

有没有办法改变这个？显而易见的答案是创建自定义AuthorizeAttribute但大多数示例，例如ASP.NET MVC 4 custom Authorize attribute - How to redirect unauthorized users to error page?的答案只需致电

 base.HandleUnauthorizedRequest();

所以在我尝试代码/调试/代码/调试路由之前寻找任何帮助！

Answer 1

public class MyAuthorizeAttribute : AuthorizeAttribute
{
    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        var sitename = filterContext.RouteData.Values["sitename"] as string;
        if (!string.IsNullOrEmpty(sitename))
        {
            var routeValues = new RouteValueDictionary(new
            {
                controller = "account",
                action = "login",
                sitename = sitename,
            });
            filterContext.Result = new RedirectToRouteResult(routeValues);
        }
        else
        {
            base.HandleUnauthorizedRequest(filterContext);
        }
    }
}
