效果：我在手機(jī)上打開微信小程序，自動(dòng)顯示出我當(dāng)前所在的地理位置：

具體步驟：

1. 使用微信jssdk提供的getLocation API拿到經(jīng)緯度；

2. 調(diào)用高德地圖的api使用經(jīng)緯度去換取地址的文字描述。

wx.ready(() => {wx.getLocation({type: "gcj02",success: function(res) {var location ="&location=" + res.longitude + "," + res.latitude;ReservationService.getGeocode(location).then(response => {if (response.data.status === "1" &&response.data.info === "OK") {self.country =response.data.regeocode.addressComponent.country;self.city = response.data.regeocode.addressComponent.city;var express ="/" +self.country +"|" +response.data.regeocode.addressComponent.province +"|" +self.city +"|" +response.data.regeocode.addressComponent.district +"|" +response.data.regeocode.addressComponent.township +"/g";self.address = response.data.regeocode.formatted_address.replace(eval(express),"");} else {// get location error, plz input addressalert("無(wú)法獲取地址信息,請(qǐng)稍后再試");}});}});

ReservationService.getGeocode的實(shí)現(xiàn)：

getGeocode(location) {

const key = '此處填入您高德地圖app的key';

return axios.post('https://restapi.amap.com/v3/geocode/regeo?key=' + key + location);

}

看下面一個(gè)使用高德地圖API將經(jīng)緯度轉(zhuǎn)換成文字描述的地址的例子，使用postman發(fā)送請(qǐng)求：

API響應(yīng)：
