uniapp接入腾讯地图实现定位导航功能。

打开腾讯地图的官网注册账号登陆进入，滑入我的头像开发者信息：https://lbs.qq.com/service/webService/webServiceGuide/webServiceOverview

2 找到添加的应用，添加key

3 webService API 查询

4 然后在manifest.json 中设置如下，以及小程序id

uniapp用到的api

uni.getLocation 获取当前的地理位置、速度。当用户离开小程序后，此接口无法调用。
uni.openLocation 使用微信内置地图查看位置
this.mapDom = uni.createMapContext('mapDom') 获取map id=mapDom 的实例
this.mapDom.includePoints includePoints 缩放视野展示所有经纬度

bug uni.getLocation 不触发直接将基础库调整为 2.17.0
