客户端的聊天内容通过json格式封装(包含聊天内容、发送人信息)之后，HTTP请求百度服务器，即请求把该消息发送到指定id的用户，请求成功之后，百度服务器就把我们的信息转发给指定的用户，对应用户再解析json格式的信息，就可以知道该消息来自何处，以及消息内容。(Chat client via json format package (includes chat, sender information), after, HTTP requests Baidu server, which sends the message to the requesting user specified id, after the request is successful, Baidu server took our information forwarded to the designated users, the corresponding user information and then parse json format, you can know that the message came from, and message content.)

说明：  ipdatabase 二叉树快速搜索IP地址数据库 数据 数据源采用2015年广告协会制定的IP地址标准数据库，中国互联网广告行业统一采用的标准IP库。 原理 利用二叉树实现IP查询，首先将10进制IPV4地址转化为二进制构建二叉树，利用二叉树搜索进行搜索，查询时间复杂度log2n，比传统IP库n的查询速度高出一个量级。(Ipdatabase Binary Tree Fast Search IP Address Database data The data source is the standard IP address database formulated by the Advertising Association in 2015, and the standard IP database adopted by the Internet advertising industry in China. principle The binary tree is used to realize IP query. Firstly, the 10-bit IPV4 address is converted into binary to construct a binary tree, and the binary tree search is used to search. The query time complexity log2n is one order of magnitude higher than that of traditional IP library n.)
