自学Python五爬虫基础练习之SmartQQ协议

　　BAT站在中国互联网的顶端，引导着中国互联网的发展走向。。。既受到了多数程序员的关注，也在被我们所惦记着。。。

　　关于SmartQQ的协议来自HexBlog，根据他的博客我自己也一步一步的去分析，去尝试，自己不了解不知道的总是神秘的，如果你有这种好奇心，那么真相就只有一个。接下来我先把协议放出来，至于分析方法，以后有机会再谈谈。。。其实我也是个半吊子水平。。。谁知道下次改了协议还灵不灵呢！

　　登录之前，获取二维码：https://ssl.ptlogin2.qq.com/ptqrshow?appid=501004106&e=0&l=M&s=5&d=72&v=4&t=0.22925435146316886，refer为：https://ui.ptlogin2.qq.com/cgi-bin/login

　　循环获取二维码状态（是否失效，是否在手机上授权）：https://ssl.ptlogin2.qq.com/ptqrlogin?webqq_type=10&remember_uin=1&login2qq=1&aid=501004106&u1=http%3A%2F%2Fw.qq.com%2Fproxy.html%3Flogin2qq%3D1%26webqq_type%3D10&ptredirect=0&ptlang=2052&daid=164&from_ui=1&pttype=1&dumy=&fp=loginerroralert&action=0-0-136435&mibao_css=m_webqq&t=undefined&g=1&js_type=0&js_ver=10139&login_sig=&pt_randsalt=0 refer为：https://ui.ptlogin2.qq.com/cgi-bin/login

　　获取cookie中ptwebqq：这次的url是手机扫描二维码之后得到的返回值。refer不变。

　　获取返回值vfwebqq：http://s.web2.qq.com/api/getvfwebqq?ptwebqq=" + ptwebqq + "&clientid=53999199&psessionid=&t=1446710396202。refer为http://s.web2.qq.com/proxy.html?v=20130916001&callback=1&id=1。

　　成功登录，得到uin，psessionid：http://d.web2.qq.com/channel/login2，refer为http://d.web2.qq.com/proxy.html?v=20130916001&callback=1&id=2，数据为："r=%7B%22ptwebqq%22%3A%22"+ptwebqq+"%22%2C%22clientid%22%3A53999199%2C%22psessionid%22%3A%22%22%2C%22status%22%3A%22online%22%7D"，host地址为："d1.web2.qq.com"

　　根据得到的信息获取好友列表：http://s.web2.qq.com/api/get_user_friends2，数据为：data="r=%7B%22vfwebqq%22%3A%22"+vfwebqq+"%22%2C%22hash%22%3A%22"+__hash+"%22%7D"，refer为：http://d.web2.qq.com/proxy.html?v=20130916001&callback=1&id=2

　　让我们来看看程序：

　　下面我们用python来尝试一下（分为两个文件，其中继续沿用我们的HttpClient类，以及WebQQ类，代码如下）：
