Google API 返回服務器位置，而不是用戶位置

Question

您好，雖然我通過此代碼獲取用戶位置，但我實際上獲取了服務器的位置，知道如何更改它以便獲取用戶位置嗎？

    public void geolocate() {
            try {

            GeolocationPayloadBuilder payloadBuilder = new GeolocationPayload.GeolocationPayloadBuilder();
            GeolocationPayload payload = payloadBuilder.createGeolocationPayload();
            //GeoApiContext context = new GeoApiContext.Builder().apiKey("my api key").build();
            // I guess the payload needs to be build in a different way but no clue how it should be :/
            GeolocationApiRequest req = (GeolocationApiRequest) GeolocationApi.geolocate(context, payload);

            GeolocationResult res = req.await();
            String location = res.location.toString();
            String[] latLngArray = location.split(",");
            com.google.maps.model.LatLng latLng = new com.google.maps.model.LatLng(Double.parseDouble(latLngArray[0]),
                    Double.parseDouble(latLngArray[1]));
            GeocodingApiRequest geoReq = GeocodingApi.reverseGeocode(context, latLng);
            GeocodingResult[] geoRes = geoReq.await();
            // Setting the user location for view
            System.out.println(geoRes[0].formattedAddress);
            origen.setValue(geoRes[0].formattedAddress);

        } catch (Exception e) {
            System.out.println("Exception in NetClientGet:- " + e);
        }
        }

這是我從中獲取對象的依賴項：

<dependency>
            <groupId>com.google.maps</groupId>
            <artifactId>google-maps-services</artifactId>
            <version>0.9.3</version>
</dependency>

希望有人可以幫助我，在此先感謝

我一直在搜索並了解如何在https://developers.google.com/maps/documentation/geolocation/intro#cell_tower_object的幫助下構建有效負載

但是我有幾個問題，我將如何獲取我的用戶 mac 地址來創建 wifiAccessPoint，以及我在哪里可以找到我所在城市（哥倫比亞卡利）的手機信號塔信息？ 只是更新將繼續搜索任何幫助表示贊賞..

Google Maps Platform 的Geolocation API不適用於獲取用戶位置，我可以建議您改用 HTML5 Geolocation， Google Maps Platform 文檔中也有一個示例。 但請注意，Google 不支持此功能，因為它使用的是 HTML5 地理位置而不是 Google API，如果您還想獲取用戶位置的地址，您可以對將由HTML5地理位置返回的坐標進行地理編碼。 您可能會看到下面的示例（沒有地理編碼功能）。 這是一個工作示例 - https://jsfiddle.net/w2sad5pn/

if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var pos = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };

      infoWindow.setPosition(pos);
      infoWindow.setContent('Location found.');
      infoWindow.open(map);
      map.setCenter(pos);
    }, function() {
      handleLocationError(true, infoWindow, map.getCenter());
    });
  } else {
    // Browser doesn't support Geolocation
    handleLocationError(false, infoWindow, map.getCenter());
  }
}
