<p style="margin-top: 0px; margin-bottom: 10px; padding-top: 0px; padding-bottom: 0px;">1.首先简单说说wifidog认证的过程


客户端首次连接到wifi后,浏览器请求将会被重定向到:


login/?gw_address=%s&gw_port=%d&gw_id=%s&url=%s


验证通过后,客户端被重定向到网关,url格式如下:


http://网关地址:网关端口/wifidog/auth?token=


wifidong会启动一个线程周期性地报告每一个用户的状态信息,并通过如下地址发送给认证


服务器:


auth_server:/auth/?stage=


ip=


mac=


token=


incoming=


outgoing=


认证服务器根据该状态信息决定是否允许该用户继续连接,并回复网关,回复格式为:Auth:状态码,


如:Auth:1


常用状态码:


0:AUTH_DENIED,表示拒绝


1:AUTH_ALLOWED,验证通过


验证通过后,将重定向到如下地址:


portal/?gw_id=%s


wifidog的ping协议


wifidog通过ping协议将当前状态信息发送给认证服务器,发送地址为:


http://auth_sever/ping/?


gw_id=%s


sys_uptime=%lu


sys_memfree=%u


sys_load=%.2f


wifidog_uptime=%lu


认证服务器须返回一个“Pong”作为回应。


具体php实现代码如下
