如何使用 Google 地点 API 获取城市的地理编码（坐标）和人口（公民人数）？ 我应该使用哪些请求？

Question

I'm developing a studying project in java spring-boot. I have used only places API (I have a key). I don't want to register at another Google API, I'm afraid about billing))

For example, the following request:

https://maps.googleapis.com/maps/api/geocode/json?address=Moscow&key=APP_KEY

finished with code 200 OK, and JSON response

{
    "error_message": "This API project is not authorized to use this API.",
    "results": [],
    "status": "REQUEST_DENIED"
}

Answer 1

I resolve the problem by getting geocode. I just get enabled Geocoding API, and my key from Places Api was usable to Geocoding API.

Now question only how to get population due to Google API.
