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

成都創(chuàng)新互聯(lián)，是成都地區(qū)的互聯(lián)網(wǎng)解決方案提供商，用心服務(wù)為企業(yè)提供網(wǎng)站建設(shè)、成都app軟件開(kāi)發(fā)、微信小程序、系統(tǒng)按需開(kāi)發(fā)網(wǎng)站和微信代運(yùn)營(yíng)服務(wù)。經(jīng)過(guò)數(shù)10年的沉淀與積累，沉淀的是技術(shù)和服務(wù)，讓客戶少走彎路，踏實(shí)做事，誠(chéng)實(shí)做人，用情服務(wù)，致力做一個(gè)負(fù)責(zé)任、受尊敬的企業(yè)。對(duì)客戶負(fù)責(zé)，就是對(duì)自己負(fù)責(zé)，對(duì)企業(yè)負(fù)責(zé)。

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：
