actionfilterattribute-应用于特定控制器类型的操作

您可以将actionfilter放在类本身上。类中的所有操作都将实现ActionFilter。

[CustomAuthorize]
public class AuthorizedControllerBase : CustomControllerBase
{
}

public class OpenAccessControllerBase : CustomControllerBase
{
}

public class MyRealController : AuthorizedControllerBase 
{
    // GET: /myrealcontroller/index
    public ActionResult Index()
    {
        return View();
    }
}

基于我的系统的评论和约束,我采用了混合方法。基本上,如果请求是通过缓存路由来的,或者“用户”由于任何原因没有设置,那么身份验证就会以正确的方式失败。

public class CustomAuthorizeAttribute : AuthorizeAttribute
{
  private MyUser User { get; set; }

  public override void OnAuthorization(AuthorizationContext filterContext)
  {
    //Lazy loads the user in the controller.
    User = ((MyControllerBase)filterContext.Controller).User;

    base.OnAuthorization(filterContext);
  }

  protected override bool AuthorizeCore(HttpContextBase httpContext)
  {
    bool isAuthorized = false;
    string retLink = httpContext.Request.Url.AbsolutePath;

    if(User != null)
    {
      isAuthorized = User.IsValidated;
    }

    if (!isAuthorized)
    {
      //If the current request is coming in via an AJAX call,
      //simply return a basic 401 status code, otherwise, 
      //redirect to the login page.
      if (httpContext.Request.IsAjaxRequest())
      {
        httpContext.Response.StatusCode = 401;
      }
      else
      {
        httpContext.Response.Redirect("/login?retlink=" + retLink);
      }
    }

    return isAuthorized;
  }
}
