我尝试使用新的 JAXL 3.0 连接到 Facebook 的聊天。他们的示例中有一个名为“echo_facebook_client.php”的示例：

我将 jid 值更改为我尝试与之聊天的 facebook 帐户的用户 ID，将 fb_app_key 更改为我的应用程序的应用程序 ID，将 fb_access_token 更改为我在请求 xmpp_login 权限时获得的访问令牌。
但是，当我运行脚本时，它一直告诉我“得到了 on_auth_failure cb，原因未授权”
但是什么不授权，为什么不授权，我有xmpp权限。
然后我在他们的文档页面上尝试了 Facebook 的示例代码，用于聊天 api，您可以在这里找到 developer.facebook.com/docs/chat/。
我给了它相同的凭据，它在第一次尝试时就能够登录，所以错误必须在 jaxl 端的某个地方。
我对 XMPP 协议一无所知，因此使用 JAXL 而不是像在 facebook 示例中那样自己编写我需要的函数会非常方便。
有人对为什么 JAXL 代码不运行有任何建议吗？上次更新是 8 天前，所以理论上它应该可以工作。
