在没有地图的背景下使用Google Places服务

Use Google Places service in the background without a map

本文关键字：Google Places 服务 背景 地图      更新时间：2023-09-26

我正在开发一款在后台运行并跟踪用户位置的Ionic应用程序。

我想做的一件事是使用谷歌的位置服务来检查距离用户所在地50米半径内是否有地下车站。如果有的话，我想通知后端进行一些额外的处理。

问题是Places服务的初始化需要您传递一个地图或一个将显示结果的节点。但由于该应用程序是在后台运行的，我不想显示任何检索到的数据，所以我没有这些数据。

是否有其他初始化服务的方法？如果没有，你知道我还可以使用其他服务吗？

您正在寻找的是Google Places API Web服务。

以下是来自网站的示例电话：

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670,151.1957&radius=500&types=food&name=cruise&key=YOUR_API_KEY

它返回：
