首先得到经纬度数据
wx.openLocation
wx.getLocation({
type: 'gcj02', //返回可以用于wx.openLocation的经纬度
success (res) {
const latitude = res.latitude
const longitude = res.longitude
wx.openLocation({
latitude,
longitude,
scale: 18
})
}})latitude ,longitude
再调用百度或者腾讯的API，根据坐标获取地理位置，或者根据地理位置获取坐标，我们这里使用根据坐标获取地理位置
https://apis.map.qq.com/ws/geocoder/v1/?location=34.34127,108.93984&key=SMJBZ-WCHK4-ZPZUA-******
上面标红的分别为坐标经纬度数据和腾讯地图key
返回的数据结果为
