关于百度地图API调用

今天做了一个关于百度地图接口的小项目，通过调用百度API：http://api.map.baidu.com/geocoder/v2/?ak=pmCgmADsAsD9rEXkqWNcTzjd&location=30.548397,104.04701&output=json&pois=1，其中ak是自己到百度注册一个开发者账号就可以拿到

返回的数据通过自己的封装就可以显示如下：

周围地点：------------附近情况--------------

地址：番禺区市桥南汇景大道

名称：汇庭雅苑

类型：房地产

标志：房地产

id：fa01e9372af45049764ff19c

坐标方向：内
