我已经复制并修改了一些 facebook 给定的聊天 api 代码,现在我想给我的朋友发送消息。我发现我们发送一个xml<message from="" to="">
来发送消息。但那并没有发生。也许是因为我不知道穿什么from
和to
属性?
编码:

那么我需要做什么才能通过这个向该用户发送消息,我尝试使用该消息创建一个 xml,但在那里被击中,任何人都可以提出一些建议,当我运行代码时,正在执行套接字启用加密之后它需要大约 20 秒的时间,然后它显示发生错误,我是否必须在我将此调用的第二个参数更改为 falsesend_xml($fp,$STREAM_XML);
后第二次删除,stream_socket_enable_crypto($fp, false, STREAM_CRYPTO_METHOD_TLS_CLIENT);
因为我没有 ssl 连接,接下来我该怎么办?
