如何在 Firebase Cloud Firestore 中保存 GeoPoint? [英] How to save GeoPoint in Firebase Cloud Firestore?

问题描述

在数据库 UI 中，我可以创建一个类型为 geopoint 的字段.提供值后，它看起来像这样:

in the database UI I can create a field with the type geopoint. After providing values, it looks something like this:

location: [1° N, 1° E]

我正在尝试通过客户端 SDK (web) 将其保存到数据库中.根据 Twitter 反馈，我尝试了 GeoJSON、Coords Array 和 Coords Object:

I'm trying to save this to the DB via client side SDK (web). Based on Twitter Feedback I tried GeoJSON, Coords Array and Coords Object:

location: [1, 2];
location: {
    latitude: 1,
    longitude: 2,
};
location: {
    "type": "Feature",
    "geometry": {
        "type": "Point",
        "coordinates": [125.6, 10.1]
    }
}

这些都没有导致数据库中的地理点类型.它们只是保存为对象/数组.

None of which resulted in the geopoint type in the database. They're just saved as Objects/Arrays.

}
