ajax请求、servlet返回json数据
1、方式一
response.setcontenttype("text/html;charset=utf-8"); response.setheader("cache-control", "no-cache"); string str = "{‘msg‘:‘成功‘,‘success‘:‘true‘}"; out.print(str); out.flush(); out.close();
ajax请求获取返回数据后, var objs=eval("("+data+")"); //转化为json对象
2、方式二
response.setcontenttype("text/x-javascript;charset=utf-8"); //或者使用 response.setcontenttype("application/json; charset=utf-8"); response.setheader("cache-control", "no-cache"); message msg = new message(); msg.setsuccess("true"); msg.setmsg("成功"); jsonobject jsonobject = jsonobject.fromobject(msg); system.out.println(jsonobject.tostring()); printwriter out = response.getwriter(); // out.print(jsonobject.tostring()); // system.out.println("ddd"); // string str = "{\"msg\":\"成功\",\"success\":\"true\"}"; out.print(jsonobject.tostring()); out.flush(); out.close();
如果使用ajax就不用再将文本转化为json对象, 因为已经在返回时指定其类型为json格式
