1、注册腾讯地图服务：申请秘钥

https://lbs.qq.com/dev/console/key/manage

2、下载qqmap-wx-jssdk文件并引入

var QQMapWX = require('../../utils/qqmap-wx-jssdk.js');
var qqmapsdk;

3、添加合法域名：

“ https://apis.map.qq.com ”
微信服务平台设置：添加到request域名下

注意：手机真机测试时，报错：request:fail url not in domain list ( 请求:失败url不在域列表中).需要多刷新几遍项目配置的域名信息

4、实例：

data: {statusBarHeight: app.globalData.statusBarHeight,page: 1,pois: [],result: [],latitude: '',longitude: ''   }, onLoad: function () {qqmapsdk = new QQMapWX({key: '秘钥'})   }, onShow: function () {let vm = this;vm.getUserLocation();   },  //授权位置信息   getUserLocation: function () {let vm = this;wx.getSetting({success: (res) => {if (res.authSetting['scope.userLocation'] != undefined && res.authSetting['scope.userLocation'] != true) {wx.showModal({title: '请求授权当前位置',content: '需要获取您的地理位置，请确认授权',success: function (res) {if (res.cancel) {wx.showToast({title: '拒绝授权',icon: 'none',duration: 1000})// vm.BackTap2()} else if (res.confirm) {wx.openSetting({success: function (dataAu) {if (dataAu.authSetting["scope.userLocation"] == true) {wx.showToast({title: '授权成功',icon: 'success',duration: 1000})//再次授权，调用wx.getLocation的APIvm.getLocation();} else {wx.showToast({title: '授权失败',icon: 'none',duration: 1000})// vm.BackTap2()}}})}}})} else if (res.authSetting['scope.userLocation'] == undefined) {//调用wx.getLocation的APIvm.getLocation();}else {//调用wx.getLocation的APIvm.getLocation();}}})   },//微信获得经纬度   
getLocation: function () {let vm = this;wx.getLocation({type: 'wgs84',success: function (res) {console.log('获得经纬度:',JSON.stringify(res))var latitude = res.latitudevar longitude = res.longitudevm.setData({latitude: latitude,longitude: longitude})vm.getLocal(latitude, longitude)},fail: function (res) {//  vm.BackTap2()}})   },//获取当前地理位置   getLocal: function (latitude, longitude) {let that = this;wx.showLoading({title: '加载中',duration: 3000})//获取当前位置信息qqmapsdk.reverseGeocoder({location: {latitude: latitude,longitude: longitude,},success:function (params) {console.log('params',params)that.setData({result:params.result})}}),//获取附近商家列表qqmapsdk.search({location: {latitude: latitude,longitude: longitude,},keyword:'小吃',page_size:10,page_index:that.data.page,header: {'content-type': 'application/json' // 默认值},success: function (res) {console.log('地理位置:',res);wx.hideLoading()let pois = res.datathat.setData({pois: that.data.pois.concat(pois),})},fail: function (res) {console.log(res);},complete: function (res) {// console.log(res);}});   },//点击进入地图  turn_map:function (e) {console.log('e',e)wx.openLocation({latitude: e.currentTarget.dataset.index.lat,longitude: e.currentTarget.dataset.index.lng,scale: 10,   //缩放比例，范围5~18name:e.currentTarget.dataset.name,address:e.currentTarget.dataset.address,})console.log('e',e)   },//下拉获取数据页数    onReachBottom:function(){let vm = this;vm.setData({page:vm.data.page+1})vm.getLocal(vm.data.latitude, vm.data.longitude)   }
