httpclient 登陆系统问题

下面程序想自动登陆系统：
public static void main(String[] args) throws Exception{   
      HttpClient client = new HttpClient();
      client.getHostConfiguration().setHost("127.0.0.1", 80,"http");

    请各位高手帮忙帮忙，小弟在此先谢过各位的帮忙，thanks！
      

  3.   

    您所请求的网址（URL）无法获取 
    用浏览器访问的话，地址是多少？
      

  4.   

    http://127.0.0.1/login/login.asp 处理登陆
    登陆后，转到http://127.0.0.1/person/resume_index.asp后面跟着参数
    当时，跳转后，想获取http://127.0.0.1/person/resume_index.asp的html就老是转回登陆页面
      

  5.   

    post.setRequestHeader("Referer", "http://127.0.0.1：8080/login/login.asp"); 
    应该是这样吧！
    愚见！
      

  6.   

    谢谢你的意见。
    因为我设置了80端口，所以http://127.0.0.1/login/login.asp
