我正在尝试实现Google的 snaptoroad API。但是我没有任何输出。我正在使用golang进行实施。我的代码如下:
mapClient, err := maps.NewClient(maps.WithAPIKey(GoogleApiServerKey))
if err != nil{
log.Println(err)
}
//Input
latlng := maps.LatLng{}
path := []maps.LatLng{}
latlng.Lat = 9.7162348
latlng.Lng = 76.6702793
path = append(path, latlng)
latlng.Lat = 9.7162400
latlng.Lng = 76.715195
path = append(path, latlng)
latlng.Lat = 9.7162410
latlng.Lng = 76.7759261
path = append(path, latlng)
inputRequest := &maps.SnapToRoadRequest{
Path: path,
}
outputResponse, err := mapClient.SnapToRoad(context.Background(), inputRequest)
fmt.Println(outputResponse)
pretty.Println(outputResponse)
此代码产生的输出是
&{[]}
&maps.SnapToRoadResponse{}
返回空白输出。有人指出我在这里犯的错误吗?提前致谢。
您的代码很好,但是您的API密钥似乎未激活。请访问googleAPI仪表板
以启用它。
您可以随时检查它是否正常运行:https
:
//roads.googleapis.com/v1/snapToRoads?path=60.170880,24.942795|60.170879,24.942796|60.170877,24.942796&key=YOUR_API_KEY
输出将是:
