目前只测试了h5的获取当前定位方法（可行），小程序和app还有待后续测试补充
借鉴了https://blog.csdn.net/Smile_ping/article/details/138705700文章内容
开发过程可能会遇到的问题
1.uni.getLocation不触发不生效
解决：不用谷歌浏览器，用edge浏览器
谷歌浏览器中没梯子是没法用的(开了梯子也不知道能不能用，看社区应该是可以，不过我没用测试），在使用调试时完全就不触发
2.在http开发环境，浏览器报错,大概就是如下提示
解决：在manifest.json中源码视图找到"h5"加入如下代码，加完以后重新跑，说是只能在https环境里调用
"devServer": {"port": 8080,"https": true,"proxy": {"/api": {"target": "https://localhost:8080","changeOrigin": true,"secure": true}}},
使用：
1.先到main.js全局注册
import location from './utils/location.js'
Vue.prototype.$location = location
2.页面内使用（用获取到的经纬度调用高德的api获取具体的位置中文名）
const that = this;
this.$location.getLocation((lb) => {console.log('位置信息', lb)let key = 'xxxxxxxxxx';//高德地图keyuni.request({// 高德url: 'https://restapi.amap.com/v3/geocode/regeo?output=json&location=' + lb.longitude + ',' + lb.latitude + '&key=' + key + '&radius=1000&extensions=all',data: {},header: {'Content-Type': 'application/json',},success: function (res) {console.log('高德地图API接口返回信息', res)let data = res.data.regeocodethat.locationInfo.address = data.addressComponent.city + data.addressComponent.district + data.addressComponent.streetNumber.street + data.addressComponent.streetNumber.number || res.data.regeocode.formatted_address || '未知位置';},})})
