服务器端:
代码很简单，就是输出一个字符串
比如正常输出json应该是：[{"id":"1","name":"测试1"},{"id":"2","name":"测试2"}]
jsonp 则输出: jsonpcallback([{"id":"1","name":"测试1"},{"id":"2","name":"测试2"}]) 其中“jsonpcallback”是客户端传过来的
- public String ajaxGetMybusAllDataJsonp(ActionForm form,
- HttpServletRequest request, HttpServletResponse response)
- throws Exception {
- String callback = request.getParameter("callback");
- JSONObject res = new JSONObject();
-
-
- res.put("d", "dddd");
-
- response.setContentType("text/html");
- response.setCharacterEncoding("utf-8");
- PrintWriter out = response.getWriter();
- out.print(callback + "(" + res.toString() + ")");
- out.flush();
- out.close();
- return null;
- }
