怎么知道你要登录的网站地址呢？（比如51job.com，模拟登录时的地址又是什么呢？求方法！）
HttpGet可以实现模拟登录吗？参数怎么带过去？(求明示！)
HttpPost提交时可以配置其List<NameValuePair> nvps = new ArrayList<NameValuePair>(); 但是这个里边又add什么东西呢？(求详细明示！)有些网站String charset = EntityUtils.getContentCharSet(entity); 拿到的编码格式是null，不转码的话就会是乱码。。。又一次伤了！
啊
啊
啊

还有最重要的一点哦，
有些网站登录成功之后会转发，不是这种Header header = response.getFirstHeader("Location");
而是如果页面配置了一个定时器，比如5s之后去windows.location.replace("登录之后的主页地址");
这种又要怎么搞呢， 我疯了！
