java 获取手机归属地，引起net.UnknownHostException错误

这个问题是请求，重定向了，跟入源码。修改了地址，变成302

Connection connect = Jsoup.connect(url);
          connect.header("Host", "http://info.bet007.com");
          connect.header("User-Agent", "  Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0");
          connect.header("Accept", "  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
          connect.header("Accept-Language", "zh-cn,zh;q=0.5");
          connect.header("Accept-Charset", "  GB2312,utf-8;q=0.7,*;q=0.7");
          connect.header("Connection", "keep-alive");
      
          Document doc = connect.get();

　　就可以获取到手机归属地了

public static String[] getPhoneAddressAndCompanyStrs(String phone){
    if(phone.length()<=0)
      return null;
    String url = "http://www.ip138.com:8080/search.asp?action=mobile&mobile=%s";
    url = String.format(url, phone);
    
    String[] strs=new String[2];
    try {
      Connection connect = Jsoup.connect(url);
          connect.header("Host", "http://info.bet007.com");
          connect.header("User-Agent", "  Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0");
          connect.header("Accept", "  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
          connect.header("Accept-Language", "zh-cn,zh;q=0.5");
          connect.header("Accept-Charset", "  GB2312,utf-8;q=0.7,*;q=0.7");
          connect.header("Connection", "keep-alive");
      
          Document doc = connect.get();
      
      Elements els = doc.getElementsByClass("tdc2");
      int elsSize = els.size();
      if(elsSize == 2) {
        strs[0]=els.get(1).text();
      }else if(elsSize > 2) {
        strs[0]=els.get(1).text();
        strs[1]=els.get(2).text();
      }
      return strs;
    } catch (IOException e) {
      
      e.printStackTrace();
      return null;
    }
  }
