[例子] 关于淘宝模拟登录的讨论

[复制链接]
发表于 2014-8-9 18:06:50 | 显示全部楼层 |阅读模式
    首先感谢下【1602264241】这位兄弟的帖子【http://www.sufeinet.com/thread-4585-1-1.html】.
    兄的业务和我基本一致,我是需要进入量子,然后使用量子不对外开放的API【不登录就不能通过API来查询数据】,来获取数据。
    业务很简单,但是有2个问题。
    1.验证码
       虽然做个do  while循环,有很大的概率登录跳过验证码进行登录(基本上循环次数都是在10次以下,但是有些还时候,验证了几百次也不能登录成功,我做的是后台定时作业,所以肯定没人输入验证码,所以就用这种方式)。
       但是毕竟失败几率也是比较高的,另外在心里总是一个结,想要解开。
        在返回的数据中的data的ccurl获取到图片链接后,把图片显示出来,输入验证码然后再次登录
        发现一个问题,我们重新post的时候,是另外一个session,而这个session和图片链接的不一样。所以就每次都提示错误
       然后想先调用https://login.taobao.com/member/ ... input_charset=utf-8  传入用户名检查是否图片验证,结果每次的结果都是false。就没办法先获取图片,然后再输入验证码。
        哪位朋友有解决方案,大家可以参考下。
     2.跳转淘宝
       我们已经可以模拟登录淘宝了,也就是说可以进入淘宝系统了,如果从当前的页面redirect到淘宝的页面,携带当前的信息跳转过去。
