安卓sdk webview获取淘宝个人信息100项，源码。

1、贴出主要代码。这个不是python，python只涉及了服务端对信息提取结果的接受。主体是java  + android + js。由于淘宝各模块都是二级子域名，不能只在一个页面完成所有请求，ajax不能跨域。需要加载不同的页面。以下是主要部分。js内容使用服务端分发。

这样做好处，即使不使用微服务，单台机器也能满足1000个用户在同一分钟提交账号密码请求登录，简化后台编写复杂度和减小服务器压力。密码 验证码的校验也更及时。

2、不是爬自己的信息，是获取别人 任意账号 + 密码的淘宝个人信息，如果是为了拿到自己的信息，搞这么多七七八八的那是闲的蛋疼。具体账号 密码是哪来的，置顶第一篇有介绍。

贴出其中一个js实例，例如提取用户所收藏物品。这里不是用直接翻页，使用的是ajax以提升效率，ajax一定需要同步方式。由于此接口是返回的页面不是json，可以用css选择器。

这就是唯一登录淘宝获取信息的方法，不管是什么语言java py，不管是用httpclient urlconnection还是urllib  requests 想达到 本篇的目的，可能性为0。不服不信的可以用httpclient urllib试试，光是一个接口登录淘宝，网上就在悬赏5万人民币了，就不说提取信息了，单是把这个接口登录淘宝解决，相当于几个月的工资了。
