ASP.NET MVC - 使用洛外部网站在用户CustomeAuthorize筛选器操作 [英] ASP.NET MVC - CustomeAuthorize filter action using an external website for loggin in the user

问题描述

我有一个CustomeAuthorize动作过滤器转发该用户，如果用户没有通过验证到登录页面。我将此过滤器应用于行动或控制器。

I have a CustomeAuthorize action filter that forwards the user to signin page if user is not authenticated. I apply this filter to actions or controllers.

[CustumeAuthorize]
public ActionResult MyAction()
{
   //do something here
   return View();
}

和过滤器看起来像这样：

and the filter looks like this:

public class CustomAuthorizeAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {

        if (!currentUserIsAuthenticated)
        {

            filterContext.Result =
                new RedirectToRouteResult(
                    new RouteValueDictionary{{ "controller", "Account" },
                                                 { "action", "SignIn" },
                                                 { "returnUrl",    filterContext.HttpContext.Request.RawUrl }
                                                });
        }
        else
        {
            base.OnActionExecuting(filterContext);
        }
    }
}

在我的值赋给filterContext.Result，过滤器完成执行后，执行是（不知何故？！）重定向到签到行动，MyAction不执行。这正是我想要的。

Once I assign a value to filterContext.Result, after execution of filter finishes, the execution is (somehow?!) redirected to the SignIn action and MyAction does not execute. This is exactly what I want.

现在说我要改变我的CustomAuthorize用户对外部网站，而不是我自己的签到行为验证，所以我做这样的事情：

Now say I want to change my CustomAuthorize to authenticate the user against an external website and not my own SignIn action so I am doing something like this:

public class CustomAuthorizeAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {

        if (!currentUserIsAuthenticated)
        {
             filterContext.HttpContext.Response.Redirect("http://externalSite.com/login?returnUrl=" + filterContext.HttpContext.Request.RawUrl);
        }
        else
        {
            base.OnActionExecuting(filterContext);
        }
    }
}

我的问题是的的CustomAuthorize过滤器的第二个版本执行完成后，继续执行到MyAction这不是我想要的！如何在这种情况下，过滤器后停止MyAction执行？

My problem is that after the execution of the second version of CustomAuthorize filter is finished, execution continues to MyAction which is not what I want! How do I stop the execution of MyAction after filter in this case?

- 更新 - 我只是碰到了新的问题来了。我的MVC应用程序是在一个iFrame，我想重定向到强制将当前帧重定向后的主框架，所以我做这样的事情：

-Update- I just came across a new issue. My MVC application is in an iFrame and I want the Redirect to force the current frame as the main frame after redirection, so I am doing something like:

string url = "http://externalSite.com/login?returnUrl=" + filterContext.HttpContext.Request.RawUrl;
filterContext.HttpContext.Response.Write("<script type=\"text/javascript\">\ntop.location.href = \"" + url + "\";</script>");

有没有办法通过一个JavaScript来RedirectResult（）？

Is there a way to pass a javascript to RedirectResult()?

推荐答案

使用类似于你如何使用RedirectToRouteResult之前更换，结果在过滤背景下RedirectResult。

Use the RedirectResult similar to how you were using the RedirectToRouteResult before to replace the result in the filter context.

filterContext.Result = new RedirectResult("http://externalSite.com/login?returnUrl=" + filterContext.HttpContext.Request.RawUrl );
