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("無法獲取地址信息,請稍後再試");
}
});
}
});
```
ReservationService.getGeocode的實現：
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);
}
看下面一個使用高德地圖API將經緯度轉換成文字描述的地址的例子，使用postman發送請求：
API響應：
