在微信小程序里自动获得当前手机所在的经纬度并转换成地址

发布时间：2019-06-22 发布网站：脚本宝典

脚本宝典收集整理的这篇文章主要介绍了在微信小程序里自动获得当前手机所在的经纬度并转换成地址，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

效果：我在手机上打开微信小程序，自动显示出我当前所在的地理位置：

具体步骤：
1. 使用微信jSSDk提供的getLocation API拿到经纬度；
2. 调用高德地图的api使用经纬度去换取地址的文字描述。


      
      
      PE: "gcj02",

success: function(res) {

VAR location =

"&amp;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 address

alert("无法获取地址信息,请稍后再试");

}

});

}

});
" title="" data-original-title="复制">
      
      

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 address

alert("无法获取地址信息,请稍后再试");

}

});

}

});

ReservationService.getGeocode的实现：
getGeocode(location) {
const key = '此处填入您高德地图app的key';
return axios.post('https://restapi.amap.com/v3/g...' + key + location);
}
看下面一个使用高德地图API将经纬度转换成文字描述的地址的例子，使用postman发送请求：

API响应：
