1.首先写个发送请求的工具类

public static String SendGET(String url,String param){
    		   String result="";//访问返回结果
    		   BufferedReader read=null;//读取访问结果
    		    
    		   try {
    		    //创建url
    		    URL realurl=new URL(url+"?"+param);
    		    //打开连接
    		    URLConnection connection=realurl.openConnection();
    		     // 设置通用的请求属性
    		             connection.setRequestProperty("accept", "*/*");
    		             connection.setRequestProperty("connection", "Keep-Alive");
    		             connection.setRequestProperty("user-agent",
    		                     "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
    		             //建立连接
    		             connection.connect();
    		          // 获取所有响应头字段
    		             Map<String, List<String>> map = connection.getHeaderFields();
    		             // 遍历所有的响应头字段，获取到cookies等
    		             for (String key : map.keySet()) {
    		                 System.out.println(key + "--->" + map.get(key));
    		             }
    		             // 定义 BufferedReader输入流来读取URL的响应
    		             read = new BufferedReader(new InputStreamReader(
    		                     connection.getInputStream(),"UTF-8"));
    		             String line;//循环读取
    		             while ((line = read.readLine()) != null) {
    		                 result += line;
    		             }
    		   } catch (IOException e) {
    		    e.printStackTrace();
    		   }finally{
    		    if(read!=null){//关闭流
    		     try {
    		      read.close();
    		     } catch (IOException e) {
    		      e.printStackTrace();
    		     }
    		    }
    		   }
    		     
    		   return result; 
    		 }

2.调用此方法，重点是访问这个获取ip的网站

SendGET("http://ip.chinaz.com/getip.aspx", "");

就能拿到\{ip:'xxx.xx.xxx.xx',address:'浙江省xx市 电信'\}

网页上通过以下代码就可以获取ip
