如何在Firebase Cloud Firestore中保存GeoPoint?

问题描述

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

location: [1° N, 1° E]

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

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

没有一个导致数据库中的geopoint类型.它们只是保存为对象/数组.

如何通过Web SDK在Firebase Cloud Firestore中保存GeoPoint?

解决方案

Firestore SDK包含 GeoPoint class ，因此您必须保存以下位置:

{
  location: new firebase.firestore.GeoPoint(latitude, longitude)
}

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]

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]
    }
}

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