现在公司有一个新的需求，前端传入经纬度，后端计算出附近的医院、派出所等等，通过查阅高德地图的Web服务开发文档，发现了以下接口：
/v3/place/around?location=经纬度&key=web服务类型的key&keywords=派出所&types=130501&radius=5000&offset=20&page=1
这里是参数的介绍
这里是返回的结果
{"status": "1","info": "OK","infocode": "10000","count": "1","suggestion": {"keywords": [],"cities": []},"pois": [{"id": "B025705MII","parent": [],"childtype": [],"name": "止马镇中心卫生院","type": "医疗保健服务;综合医院;卫生院","typecode": "090102","biz_type": [],"address": "止马镇止马中路1号","location": "117.169901,27.471023","tel": "0599-7771221;0599-7772778","pname": "福建省","cityname": "南平市","adname": "光泽县","importance": [],"shopid": [],"shopinfo": "2","poiweight": [],"distance": "255","biz_ext": {"rating": [],"cost": []},"photos": [{"title": [],"url": "http://store./showpic/beceaa81b666376821c4c7819160742a"}]}]}
这里是从返回的json中拿名称、经纬度和电话的代码
String resultStr = HttpUtils.get("/v3/place/around?location=" + location + "&key=你的key&keywords=派出所&types=130501&radius=5000&offset=20&page=1");JSONObject resultJson = JSONObject.parseObject(resultStr);JSONArray pois = resultJson.getJSONArray("pois");String tel = pois.getJSONObject(0).getString("tel");String name= pois.getJSONObject(0).getString("name");String location= pois.getJSONObject(0).getString("location");
