Question

我有这个动作脚本代码块，在登录被占用时执行。我试图为用户重新加载一组角色。我已经为hasRole（）方法添加了一个结果处理程序

[Observer("loginAttempted")]
public function loginAttempted():void {
    identity.isLoggedIn(isLoggedInResult);

    trace(identity.loggedIn+" "+identity.username);
    var perms:Array = Permission.constants;
    var i:int
    trace("Load permissions");
    for(i=0;i<perms.length;i++)
    {
        var p:Permission = perms[i];
        var res = identity.hasRole(p.name,permissionResult);
        if(res == true)
        {
            p.allowed = res;
        }
        trace(i+" "+p.name +" "+p.allowed+" "+res);
    }
}

private function permissionResult(event:TideResultEvent):void {
    trace("permissionResult "+event.result);
}

但我一直收到这个错误。基于graniteds docs，函数应该只接受一个参数。

我们在标识上使用ifAnyGranted函数做类似的事情，我们的结果处理程序有2个参数：TideResultEvent和包含该角色的String。尝试将permissionResult函数的签名更改为：

private function permissionResult(event:TideResultEvent, role:String):void

Graniteds - ejb.Tide - Identity.hasRole（）函数 - 无效参数
