服務端servlet代碼片段：
/**
* 處理請求
* @throws IOException
*/
private void requestManage(HttpServletRequest req, HttpServletResponse res) throws IOException{
//配置編碼類型
res.setContentType("text/html;charset=UTF-8;pageEncoding=UTF-8"); //控制瀏覽器的編碼行爲
res.setCharacterEncoding("UTF-8");//目的是用於response.getWriter()輸出的字符流的亂碼問題，如果是response.getOutputStream()是不需要此種解決方案的；因爲這句話的意思是爲了將response對象中的數據以UTF-8解碼後發向瀏覽器；
res.setHeader("content-type","text/html;charset=UTF-8");
req.setCharacterEncoding("UTF-8");
String jason="{\"currentNumber\":10,\"pageNo\":1,\"pageSize\":10,\"rows\":[{\"email\":\"[email protected]\",\"firstname\":\"fname1\",\"id\":3,\"lastname\":\"lname1\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname2\",\"id\":4,\"lastname\":\"lname2\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname3\",\"id\":5,\"lastname\":\"lname3\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname4\",\"id\":7,\"lastname\":\"lname4\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname5\",\"id\":8,\"lastname\":\"lname5\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname6\",\"id\":9,\"lastname\":\"lname6\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname7\",\"id\":10,\"lastname\":\"lname7\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname8\",\"id\":11,\"lastname\":\"lname8\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname9\",\"id\":12,\"lastname\":\"lname9\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"[email protected]\",\"firstname\":\"fname10\",\"id\":13,\"lastname\":\"lname10\",\"phone\":\"(000)000-0000\",\"valid\":true}],\"total\":11,\"totalPages\":2}";
String callback=req.getParameter("callback");//得到回調函數名
System.out.println(callback);
res.getWriter().write(callback+"("+jason+")");//封裝成 回調函數名（data）形式
