根据以上设计原理，暂时不考虑安全，用户认证等问题，服务器端需要提供的http接口有：
1：用户登录接口
?????? 参数：deviecode，设备识别码，读取CPU或者硬盘序列号
?????? 返回：当前用户识别码和验证码
2：用户刷新验证码
?????? 参数：识别码，验证码
?????? 返回：新的验证码
3：心跳接口
?????? 参数：识别码，验证码
?????? 返回：如果有链接请求，返回链接的ip与端口
4：链接请求，接收链接请求，创建链接记录
?????? 参数：被控制端识别码，验证码
?????? 返回：如果成功，返回链接的ip与端口
表设计用户表：
表设计会话表：
http服务器端开发，使用eclipse，maven，springboot，mybatis，这些东西就比较过了，过程不表，贴上核心代码。
