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,并将fb_access_token更改为我在请求xmpp_login权限时获得的访问令牌。
然而,当我运行脚本时,它一直告诉我"got on_auth_failure cb with reason not authorized"
但是什么是未授权的,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的聊天api示例代码,你可以在这里找到开发者。facebook.com/docs/chat/.
我给了它相同的凭据,它能够在第一次尝试时登录,所以错误一定在jaxl端的某个地方。
我对XMPP协议一无所知,所以使用JAXL将非常方便,而不是像在facebook示例中那样自己编写所需的函数。
有人对JAXL代码为什么不运行有什么建议吗?最后一次更新是在8天前,所以理论上它应该可以工作。
您只需将'force_tls' => true
作为JAXL构造函数配置选项传递即可。根据https://developers.facebook.com/docs/chat/#jabber已经进行了tls协商x-facebook-platform身份验证是强制性的。
jaxl组/论坛中的相关线程https://groups.google.com/forum/?hl=en_US&来自组#!topic/jaxl/Z7z32lMqG44讨论了这个用例。
