URLConnection應用,與遠端做資料溝通

//傳送物件到遠端
    URL url = new URL("遠端網址");
    URLConnection urlConnection = url.openConnection();
    urlConnection.setDoOutput(true);
    urlConnection.setDoInput(true);
    urlConnection.setUseCaches(false);
    urlConnection.setDefaultUseCaches(false);
    urlConnection.setRequestProperty("Content-Type", "application/x-java-serialized-object");

    ObjectOutputStream ous = new ObjectOutputStream(urlConnection.getOutputStream());      
    ous.writeObject(cgsNums);
    ous.writeObject(qcOrders);
    ous.writeObject(cpdtOwner);
    ous.flush();
    ous.close();

//遠端將資料組合後
//讀取網頁
 StringBuffer html = new StringBuffer();
 BufferedReader br = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
    String inputLine;
    while ((inputLine = br.readLine()) != null) {
        html.append(inputLine).append("\r\n");
    }
