我在使用以下代码时遇到问题：

    this.fb_init();
}

private function fb_init():void {
    Facebook.init("xxxxxxxxxxxxxxx",fb_handleInit);
}

private function fb_handleInit(success:Object,fail:Object):void {

    if (success && success.uid) {
         fb_loggedIn(success);
    }else{
        show_FacebookLoginButton();
    }

}

private function show_FacebookLoginButton():void {
    ....
}

private function handleMouseDown_FacebookLoginButton(event:MouseEvent):void {
    _stage.removeChild(_fb_login_button);
    this.fb_login();
}

private function fb_login():void {
    Facebook.login(fb_handleLogin,{scope:"user_games_activity,friends_games_activity"});
}

private function fb_handleLogin(success:Object=null,fail:Object=null):void {
    if (success) {
        fb_loggedIn(success);
    }else{
        show_FacebookLoginButton();
    }
}

private function fb_loggedIn(response:Object) {
    trace("success!);
}

首先，在 fb_handleInit(success:Object,fail:Object) 中，成功和失败都始终为空。

其次，在登录后（或者如果已经登录则立即），fb_handleLogin(success:Object=null,fail:Object=null) 永远不会被调用，并且 flash 会输出以下错误：

ReferenceError: Error #1069: Property expiresIn not found on String and there is no default value.
    at com.facebook.graph.data::FacebookAuthResponse/fromJSON()
    at com.facebook.graph::Facebook/handleAuthResponseChange()
    at Function/http://adobe.com/AS3/2006/builtin::apply()
    at flash.external::ExternalInterface$/_callIn()
    at Function/<anonymous>()

Firebug 显示此错误消息：未捕获的异常：Actionscript 中的错误。使用 try/catch 块来查找错误。xd_arbiter.php 第 13 行 (http://static.ak.facebook.com/connect/xd_arbiter.php)

Chrome 显示此错误消息：未捕获的错误：在 NPObject 上调用方法时出错。

I've been googling and reading about it for a few days, and I've posted an issue at http://code.google.com/p/facebook-actionscript-api/ with no response so far. I'm surprised the the lack of examples that I can find. I've found a few and tried them and still had problems.

Facebook made some changes in auth process, the old version of as3 library (last update of facebook-actionscript-api was in oct. 2011 as mentioned here code.google.com/p/facebook-actionscript-api/downloads/list) can result in such errors. Try to find library that's supported.
