另一种网络请求

private InputStream loginByServerByPost(String url1) {        InputStream rs = null;        URL url = null;        HttpURLConnection urlConn = null;        try {            url = new URL(url1);// 创建和服务器的连接对象URL            urlConn = (HttpURLConnection) url.openConnection();// 打开连接            urlConn.setConnectTimeout(5 * 1000);// 设置连接超时容忍时间            urlConn.setReadTimeout(5 * 1000);// 设置读取时间            if (urlConn.getResponseCode() == 200) {// 如果响应码为200表示响应成功，并且同时成功的相应了数据                // 获得服务器相应的数据，字节输入流（数据流），转换为缓存字符流便于读取                rs = urlConn.getInputStream();            }        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return rs;// 转换为字符串，返回    };
