【问题描述】：

我已经成功通过 xmpp 协议登录到 facebook。

我使用了此处找到的 facebook 文档中提供的 php 代码：

_main();

我几乎了解所有内容，但我没有看到任何用于检索在线列表、发送/接收消息的文档。

【参考方案1】：

发送<presence />上线。 然后服务器会给你发几个<presence from='[e-mail]/deviceID' />表示在线好友。

发送这样的消息：

<message from='[e-mail]' to='[e-mail]'>
    <body>Art thou not Romeo, and a Montague?</body>
</message>

【讨论】：

在哪里？在调用 _main() 之后？打印后“完成”;

我在 fclose($fp); 之前的 xmpp_connect 函数中添加了我的代码--------- send_xml($fp, "<presence />"); print ("go online done<br>\n"); send_xml($fp, "<message from='[e-mail]' to='[e-mail]'><body>55</body></message>"); ----- 上网部分完成，但消息未发送！！。为什么 ？？请提供任何帮助

嗨 Joakim ...我尝试了 但 facebook 花了很长时间并最终显示超时错误..虽然我能够向用户发送消息..但无法获得在线用户..请帮助

不会有响应，所以不要等待。相反，您会收到几条单独的 消息，因此您必须监听传入的消息。
