httpclient 人人网

登录的站点是3g.renren.com 因为是手机人人，页面比较简单

首先用HttpGet取出"http://3g.renren.com"的html代码，是用Jsoup解析出登录表单，包括验证码的图片的url

因为没法做到绕过验证码，所以用验证码的url构建一个image，显示出来让用户自己填写

构建image时一定要用httpget，开始使用了ImageIO.read(new URL(url)); 这样， HttpClient实例中没有管理session

不写了，全放到注释里去了，直接上代码

因为程序很依赖html源码，哪天人人的前台改动了html代码说不定就用不了了
