开发场景获取以后地位信息或者某地的行政区划信息或者街道信息，实现相似电商平台填写收货地址性能。
技术选型微信小程序JavaScript SDK
微信小程序插件
确定业务逻辑及页面设计以简洁大气为主，款式抉择weui。
具体开发过程1、首先注册小程序，我以前有就没从新申请。
2、注册腾讯位置服务开发者
须要留神的是：集体开发者接口调用数是有限额的，收费额度1W，并发数5，申请成为企业用户可收费晋升更大配额。
3、依据文档开发。
文档写的比拟全，很多中央都是例子，不过须要留神以下几个点：
1）reverseGeocoder接口返回数据和文档不统一，须要依据理论返回值编写，另外有些字段在返回值中不肯定有，最好用hasOwnProperty进行判断后赋值。
2）实际上文档有点乱，须要查看多个中央的文档。
