如何在Firebase Cloud Firestore中保存GeoPoint？

Question

在数据库UI中,我可以创建一个具有该类型的字段geopoint.提供值后,它看起来像这样:

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.基于Twitter反馈我尝试了GeoJSON,Coords数组和Coords对象:

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

这些都不会导致数据库中的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？

Answer 1

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

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

Answer 2

我努力找出正确的导入/要求。这对我有用！！

const firebaseAdmin = require('firebase-admin');
//other code ....

//assigning value to myLocation attribute
let newObject = {
    otherAttribute:"otherAttributeValue",
    myLocation: new firebaseAdmin.firestore.GeoPoint(latitude,longitude)
}

Answer 3

只需使用：

import 'package:cloud_firestore/cloud_firestore.dart';
{
  location:GeoPoint(latitude, longitude)
}
