什么是wifidog认证功能?什么是wifidog?

wifidog是路由器的一种上网认证功能, 如果开启此功能, 所有通过路由器上网的设备(电脑,笔记本,手机等)都会跳转到指定的界面, 需要通过某种方式认证才可以上网.

具体这种wifidog功能路由器系统(固件)有DD-WRT ,OPEN-WRT等.
以DD-WRT 系统为例,可以在"服务--->热点" 找到WIFIDOG功能 ,如下图:

针对OPENWRT中WIFIDOG不稳定的优化和改进

最近在做 wifidog 的广告功能，发现 wifidog 有很多不稳定的地方，急待改进和优化。于是自习研究了 wifidog 的工作流程，结合自己的需求，简化了认证过程，流程图如下：
1.jpg

正常 wifidog 认证流程10步以上，而6次是与服务器端的直接通信。其中重复向服务器发送数据的一项可以完全省略，这样精简了认证流程可以减少4次网络传输，使每个上网用户只需要一次请求即可认证上网。认证流程优化至6步且4步是在本地通信。
注意此种方案中token的产生要在wifidog和服务器端协调一致。其实就是通过算法代替了网络认证问题。

广告路由器开发(二)实践-wifidog版

上篇文章中分析了wifidog下authpuppy之间的数据流这篇文章中我就介绍一下如何书写一个简单的广告路由器
经过以上分析不难看出 实现一个广告路由器还是非常简单的
由于我本人对symfony框架不感冒 故以下示例代码使用了phalcon框架进行书写（只是演示用而已）

<?php  

namespace controllers;  

class InterfaceController extends \Phalcon\Mvc\Controller  
{  

    public function initialize( )  
    {  

    }  

    public function indexAction( )  
    {  
    }  

    public function loginAction( )  
    {  
        if( $this->request->isGet() && null == $this->request->getQuery( 'advs' ) )  
        {  
            $strDebug = var_export( $_SERVER, true );  

            $this->view->setVar( 'iRefreshTime', 10 ); //广告时间10秒  
            $this->view->setVar( 'url', $this->request->getServer( 'REQUEST_URI' ) . '&advs=advs' );  

            $this->view->pick( 'interface/advs' );//这里展示广告  
        }  
        else  
        {  
            $this->view->disable();  

            $strToken = sha1( rand() . time() );  
            $this->persistent->set( 'redirectUrl', $this->request->getQuery( 'url' ));  
            $this->response->redirect( 'http://' . $this->request->get( 'gw_address' ) . ':' . $this->request->get( 'gw_port' ) . '/wifidog/auth?token=' . $strToken, true );  
        }  

    }  

    public function logoutAction( )  
    {  
        echo 'Auth:0';  
    }  

    public function portalAction( )  
    {//广告过后在此函数内进行跳转  
        $this->view->disable();  
        if( null != $strUrl = $this->persistent->get( 'redirectUrl' ) )  
        {  
            $this->response->redirect( $strUrl, true );  
        }  
        else   
        {  
            $this->response->redirect( 'http://blog.csdn.net/qzfzz', true );  
        }  
    }  

    public function pingAction( )  
    {  
        echo 'Pong';  
    }  

    public function msgAction( )  
    {  
    }  

    public function authAction( )  
    {  
        echo 'Auth: 1';  
    }  

}

以下为视图

<!--advs.phtml-->  
<!doctype html  
<html>  
<head>  
<meta http-equiv="refresh" content="<?php echo $iRefreshTime;?>;url=<?php echo $url;?>"/>  
<title>Login</title>  
</head>  
<body>  
<p>这里可以展示广告等信息</p>  
</body>  
</html>

经过以上的开发一个简单的广告路由器即完成了

广告路由器开发(一)数据流-wifidog版

最近无事时对广告路由器进行了一个分析
常用的广告路由器一般是通过普通路由器刷openwrt或是ddwrt等固件后安装wifidog组件做的，我们这里分析的即是wifidog加authpuppy
以下数据为截取自authpuppy和wifidog的交互

1.用户请求页面http://www.gov.cn/guowuyuan/2014-09/23/content_2755108.htm

3. 在2中进行跳转后则WiFiDog服务器向授权服务器端发送GET授权请求 若成功则而返回Auth: 1  
--------------------------------------------------------------------------------------  
request:  
/auth/?stage=login&ip=192.168.4.186&mac=00:0e:c6:f0:06:b2&token=60bb7efe229270c4d6d36ed60bb5e98886900126&incoming=0&outgoing=0&gw_id=default  

response://千万要注意这里Auth:与1之间有一个空格否则不能通过验证  
Auth: 1

  'REQUEST_TIME' => 1411547194,  
)  
++++++++++++++++++++++++++++++++++++++++++++++++  

4.WiFiDog在接收到Auth:1之后向服务器端发送/portal/?gw_id=default的GET请求 授权服务器返回立即跳转的页面如下：  
--------------------------------------------------------------------------------------  
request:  
/portal/?gw_id=default  

reponse:

5.WiFiDog服务器向授权服务器发送ping操作请求 服务器端通过后发送Pong响应串(纯文本)  
--------------------------------------------------------------------------------------  
request:  
/ping/?gw_id=default&sys_uptime=28824&sys_memfree=99284&sys_load=0.08&wifidog_uptime=61
