接下来是前台代码
<script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.js"></script>
<script>
$('#search').click(function () { $.ajax({ type: 'GET', url: 'http://192.168.1.106:7777/test_post/aa', dataType: 'jsonp', //希望服务器返回json格式的数据 jsonp: "callback", jsonpCallback: "successCallback",//回调方法 success: function (data) { console.log(data); } }); }); </script>
接下来就可以看到控制台数据了
