mvc登录授权特性

public class CommonAuthorize : AuthorizeAttribute
{
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
return UserHelper.CurrentUser != null;
}

public override void OnAuthorization(AuthorizationContext filterContext)
{
if (!filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true) && !filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true))
{
if (UserHelper.CurrentUser == null)
{
filterContext.Result = new RedirectResult(string.Format("/OAuth2/IndexUserInfo?returnUrl={0}", filterContext.HttpContext.Request.RawUrl));
}
