uni-app微信小程序获取所在城市附源码下载

最近在用uni-app开发小程序，需要获取用户所在城市，小程序本身没有这样的api，那么怎么实现呢？


1、申请开发者密钥（key）：申请密钥

2、下载腾讯位置服务jssdk

下载完成后放入utils文件夹下引用即可



//index.js
//获取应用实例
const app = getApp();
var QQMapWX = require('../../utils/qqmap-wx-jssdk.min.js');
var qqmapsdk;
Page({
  data: {
    province: '',
    city: '',
    latitude: '',
    longitude: ''
  },
  onLoad: function () {
    qqmapsdk = new QQMapWX({
      key: 'xxxx-xxxx-xxxx-xxxx' //自己的key秘钥 http://lbs.qq.com/console/mykey.html 在这个网址申请
    });
  },
  onShow: function () {
    let vm = this;
    vm.getUserLocation();
  },
  getUserLocation: function () {
    let vm = this;
    wx.getSetting({
      success: (res) => {
        console.log(JSON.stringify(res))
        // res.authSetting['scope.userLocation'] == undefined    表示 初始化进入该页面
        // res.authSetting['scope.userLocation'] == false    表示 非初始化进入该页面,且未授权
        // res.authSetting['scope.userLocation'] == true    表示 地理位置授权
        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
                })
              } 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API
                      vm.getLocation();
                    } else {
                      wx.showToast({
                        title: '授权失败',
                        icon: 'none',
                        duration: 1000
                      })
                    }
                  }
                })
              }
            }
          })
        } else if (res.authSetting['scope.userLocation'] == undefined) {
          //调用wx.getLocation的API
          vm.getLocation();
        }
        else {
          //调用wx.getLocation的API
          vm.getLocation();
        }
      }
    })
  },
  // 微信获得经纬度
  getLocation: function () {
    let vm = this;
    wx.getLocation({
      type: 'wgs84',
      success: function (res) {
        console.log(JSON.stringify(res))
        var latitude = res.latitude
        var longitude = res.longitude
        var speed = res.speed
        var accuracy = res.accuracy;
        vm.getLocal(latitude, longitude)
      },
      fail: function (res) {
        console.log('fail' + JSON.stringify(res))
      }
    })
  },
  // 获取当前地理位置
  getLocal: function (latitude, longitude) {
    let vm = this;
    qqmapsdk.reverseGeocoder({
      location: {
        latitude: latitude,
        longitude: longitude
      },
      success: function (res) {
        // console.log(JSON.stringify(res));
        let province = res.result.ad_info.province
        let city = res.result.ad_info.city
        vm.setData({
          province: province,
          city: city,
          latitude: latitude,
          longitude: longitude
        })

      },
      fail: function (res) {
        console.log(res);
      },
      complete: function (res) {
        // console.log(res);
      }
    });
  }
})

效果图：
