问题描述
Hello Stackoverflow Community，
Hello Stackoverflow Community,
我目前正在与Facebook Chat API混淆。我想通过应用程序发送聊天消息到我的Facebook联系人。
I am currently messing about with the Facebook Chat API. I want to send chat messages to my facebook contacts via an App.
使用Facebook提供的示例，我可以连接到Facebook聊天服务器。
但是这里有更多的尝试和错误的事情。我只能模糊地理解请求和响应的发送和接收。
Using the example provided by facebook I was able to connect to the facebook chat server. But that had more of an trial and error thing here. I could only vaguely understand how requests and responses are sent and received. It would be great if someone could provide further explanation or further reading.
我的实际问题是：如何在连接到聊天服务器后发送消息？
My actual question is: How can I send messages after connecting to the chat server?

我知道这里已经有一个这样的问题（ facebook chat api-php ）。但是这是一个很老的话题，也许Facebook在聊天api中改变了一些东西。
I know there is already a question like this here (facebook chat api - php). But it's a pretty old topic and maybe facebook changed something in their chat api.
提前感谢

Thanks in advance Thomas
推荐答案
您应该发送到socket命令与您的消息。通用消息格式是
You should send to socket command with your message. Common message format is
<message from="-sender_ID@chat.facebook.com" to="-receiver_ID@chat.facebook.com">
<body>message body</body>
</message>
所以在评论之前我们做了！插入函数调用send_xml与消息模板
So before comment "we made it!" insert function call send_xml with your message template
send_xml($fp, $MESSAGE);
if (!find_xmpp($fp, 'BODY')) {
return false;
}
