抓取二维码下载链接
首先是个GET请求(Request Method中查看)
其次URL为

登陆抓包准备
左上角按钮能够控制浏览器的抓包状态,如果将它点为灰色的话,浏览器将停止抓包固定住抓包的数量和位置并不会清空。
其次按钮为改变浏览器的运行速率,如果出现网速过快现象使得抓包来不及按,我们可以将前后端发送速率改为缓慢3G网速,这样就能轻松点到截止抓包了。(手速慢才会用这个,比如我)

我们拦截到这些登陆包,一个个寻找登陆所需要的主要包。
关于登陆包只有一个URL为https://ssl.ptlogin2.qq.com/ptqrlogin
参数为:u1: https://graph.qq.com/oauth2.0/login_jump

棘手的可变加密参数
第一个参数
params.ptqrtoken=$.str.hash33($.cookie.get("qrsig"))pt.ptui.login_sig=pt.ptui.login_sig||$.cookie.get("pt_login_sig");
ptqrtoken参数需要获取cookie中的qrsig键的值信息后经过hash33加密处理。login_sig参数需要获取cookie中的pt_login_sig键的值信息即可。
一个是点击登陆按钮出现弹窗那一刻有可能出现该参数。
一个是弹出二维码或QQ登陆信息时有可能出现该参数。
