最近公司有一个需求，有一批数据只有经纬度没有确定地址，现在需要根据经纬度补全地址，刚好高德提供这么一个API，可以拿来使用。
不过因为提供的数据的经纬度是大地2000坐标系，跟高德坐标系还不一样，需要进行一次转换。
我网上找到Go语言版本的坐标系转换工具类https://github.com/atopx/coord，可以根据go get github.com/yanmengfei/coord
编程请求
package mainimport ("fmt""io""net/http""github.com/yanmengfei/coord"
)func main() {//WGS-84坐标系，GPS设备获取的经纬度坐标,地球坐标系，国际通用坐标系//GCJ-02坐标系，火星坐标系，WGS84坐标系加密后的坐标系；Google国内地图、高德、QQ地图等使用var location = "120.584495,30.14854"var lon, lat, _ = coord.LocationToFloat64Coord(location)fmt.Println("WGS84:", lon, lat)lon, lat = coord.WGS84toGCJ02(lon, lat)fmt.Println("GCJ02:", lon, lat)const requestUrl string = "https://restapi.amap.com/v3/geocode/regeo"request, err := http.NewRequest("GET", requestUrl, nil)if err != nil {fmt.Println("Error:", err)panic(err)}params := request.URL.Query()params.Add("key", "高德API密钥")params.Add("location", fmt.Sprintf("%f,%f", lon, lat))request.URL.RawQuery = params.Encode()client := &http.Client{}response, err := client.Do(request)if err != nil {fmt.Println("Error:", err)panic(err)}defer response.Body.Close()body, err := io.ReadAll(response.Body)if err != nil {panic(err)}fmt.Println("adress:" + string(body))
}
返回结果
