  OutputStream os = con.getOutputStream（）; 
 BufferedWriter bw = new BufferedWriter（new OutputStreamWriter（os，“UTF-8”））; 
 String data = URLEncoder  .encode（“查询”，“UTF-8”）+“=”+ URLEncoder.encode（查询，“UTF-8”）; 
 bw.write（数据）; 
 bw.flush（）;

答

Simply append another parameter with &

String data = URLEncoder.encode("Query", "UTF-8")+"="+URLEncoder.encode(query,"UTF-8");
       data+= "&"+URLEncoder.encode("Tags", "UTF-8")+"="+URLEncoder.encode(yourTags,"UTF-8");

Note : For efficiency use StringBuilder

StringBuilder params = new StringBuilder();
params.append(URLEncoder.encode("Query", "UTF-8")+"="+URLEncoder.encode(query,"UTF-8"));
params.append("&");
params.append(URLEncoder.encode("Tags", "UTF-8")+"="+URLEncoder.encode(yourTagStr,"UTF-8"));
bw.write(params.toString());
// ... code
