我看到很多应用程序，我们可以在其中找到当前位置附近的酒店、咖啡馆、历史遗迹。我的问题是这些应用程序如何在内部工作。我想使用谷歌地图找到我所在位置附近的所有沙龙。

提前致谢

对于 SO 来说，这并不是一个真正的问题。

你应该在这里分享一些代码。

从技术上讲，该应用程序正在访问您的设备以获取您的实际位置。该位置被发送到谷歌服务以获取附近的场地。

以下是您正在寻找的 API 文档：

https://developers.google.com/places/documentation/search#PlaceSearchRequests

到该位置 500 m 半径内的酒店 + 咖啡馆的示例 JSON 请求可能如下所示：

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=lodging|cafe&sensor=false&key=
