前言

最近发现服务器上淘宝的cookie总是未登录状态的cookie.通过log发现登录时,淘宝会强制加滑块,而且通过模拟滑动滑块,总是会提示:

<div id="nocaptcha" class="nc-container tb-login" data-nc-idx="1" style="display: block;"><div class="errloading"><i class="nc_iconfont icon_warn"></i><span class="nc-lang-cnt" data-nc-lang="_error300">哎呀，出错了，点击<a href="javascript:noCaptcha.reset(1)">刷新</a>再来一次</span></div></div>
看来淘宝已经对模拟登录抓取cookie的行为动作进行了一些判断.

解决思路

将模拟登录全部放到windows系统,使用FirefoxDriver,通过服务器的IP代理请求,即可.
