今天在用android 的
URL url = new URL("http://www.my400800.cn &search=400电话 ");
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
时传递到服务端的中文字符时乱码，最后是将要发送的字符经过编号就可以了代码修改如下：
URL url = new URL("http://www.my400800.cn &search="+java.net.URLEncoder.encode("400电话 "));
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
