微信小程序通过startLocationUpdate，onLocationChange获取当前地理位置信息，配合腾讯地图解析获取到地址

先创建个getLocation.js文件

//获取用户当前所在的位置
const getLocation = () => {return new Promise((resolve, reject) => {let _locationChangeFn = (res) => {resolve(res) // 回传地里位置信息wx.offLocationChange(_locationChangeFn) // 关闭实时定位wx.stopLocationUpdate(_locationChangeFn); // 关闭监听 不关闭监听的话，有时获取位置时会非常慢}wx.startLocationUpdate({success: (res) => {wx.onLocationChange(_locationChangeFn)},fail: (err) => {// 重新获取位置权限wx.openSetting({success(res) {res.authSetting = {"scope.userLocation": true}}})reject(err)}})})
}module.exports = {getLocation
}

在App.vue文件里引入封装的getLocation.js文件

<script>
import getLocation from "./pages/common/getLocation.js";
import { addUserTrail } from "@/api/promote.js";
var QQMapWX = require("./common/qqmap-wx-jssdk.js");//引入腾讯地图逆解析地址
var qqmapsdk;
export default {data() {return {latitude:'',longitude:''};},onLaunch: function () {setInterval(function () {//定时任务判断登录的角色在调用getLocation.jsif (uni.getStorageSync("ROLE_NAME") !== null &&uni.getStorageSync("ROLE_NAME") !== "" &&uni.getStorageSync("ROLE_NAME") === "BD") {getLocation.getLocation().then((res) => {console.log('当前所在位置的经纬度为：')console.log(res.latitude,res.longitude)const addUserTrailBody = {latitude: null,longitude: null,address: "",};addUserTrailBody.latitude = res.latitude;addUserTrailBody.longitude = res.longitude;addUserTrail(addUserTrailBody);});}}, 90000);},methods: {getMapAddress() {const that = this;const tMap = new QQMapWX({key: "xxx", //腾讯地图开发者密钥key});uni.getLocation({type: "wgs84",isHighAccuracy: true,success: (res) => {console.log(res);},fail: () => {console.log("获取经纬度失败");},complete: () => {tMap.reverseGeocoder({//逆解析location: {latitude: that.latitude,longitude: that.longitude,},success: function (res) {console.log("解析地址成功", res);console.log("当前地址：", res.result.address);const addUserTrailBody = {//拿到地理位置传递下latitude: null,longitude: null,address: "",};addUserTrailBody.latitude = res.latitude;addUserTrailBody.longitude = res.longitude;addUserTrailBody.address = res.address;addUserTrail(addUserTrailBody);uni.setStorage({key: "local",data: res.result.address,success() {console.log("用户地址信息已缓存");},});},fail: function (res) {uni.showToast({title: "定位失败",duration: 2000,icon: "none",});console.log(res);},complete: function (res) {//无论成功失败都会执行console.log("获取定位信息");return;uni.openLocation({latitude: that.latitude,longitude: that.longitude,success: function () {console.log("success");},});},});},});},    },
};
</script>

要在manifest.json文件里配置下内容

"permission": {"scope.userLocation": {"desc": "你的位置信息将用于定位效果展示"}
},
"requiredPrivateInfos": ["getLocation","onLocationChange","startLocationUpdate","chooseLocation"
],"requiredBackgroundModes": ["location"
]
