取得url地址寫入參數

String query="";

String encoding="UTF-8";

query += "&" ;
     query += URLEncoder.encode(name.toString(),encoding) + "=" +
     URLEncoder.encode(value.toString(),encoding);//進行編碼轉換；query中包含所有要傳遞的參數。

URLConnection conn = url.openConnection();
  conn.setUseCaches(false);
  conn.setDoOutput(true);
  ((HttpURLConnection)conn).setRequestMethod("POST");

  OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
//  qs.add("sessionid",Session.instance().getSessionID());
  
  out.write(qs.toString());
  //out.write("/r/n");
  //out.write("/r/n");
  out.flush();
  out.close();
