URLConnection中url参数为中文的处理

使用URLConnection进行http连接的时候会遇到参数为中文的情况，这个时候需要使用URLEncoder.encode把参数部分单独处理一下再拼接到url上：

String num=URLEncoder.encode(number,"UTF-8");    String url="http://xx.xx.xx.xx:xx/getTraffic?lineID="+num;URLConnection connection = null;StringBuffer buffer = new StringBuffer(); BufferedReader br=null;  try {       connection = new URL(url).openConnection();       connection.connect();       InputStream fin = connection.getInputStream();       br = new BufferedReader(new InputStreamReader(fin,"UTF-8"));                   String temp = null;       while ((temp = br.readLine()) != null) {                buffer.append(temp);            }                         }catch (IOException e){ }
