我们正在使用geofirestore npm package来获取附近的文档。
这是我们用来获取这些文档的Cloud Function。
exports.getNearbyOffers = functions.https.onCall((data, context) => {
const offers = GeoFirestore.collection('restaurants');
const center : GeoPoint = new admin.firestore.GeoPoint(data["sourceLat"], data["sourceLng"]);
const query = offers.near({center: center, radius: 100,});
return query.get().then((value) => {
console.log(value.docs);
return value.docs;
}).catch((err: any) => {
console.log(err);
});
});
客户端的输出是:
[{data: {}, distance: 0, exists: true, id: LdaLz30gv16Gv68Xw92i}, {data: {}, distance: 0, exists: true, id: Ux1Et5afklvZC4IKEkJy}, {data: {}, distance: 0, exists: true, id: h4kdFZpsn1UwPpTvPMxC}, {data: {}, distance: 0, exists: true, id: oqWfc41cfiWAcnvufVFd}, {data: {}, distance: 0, exists: true, id: pH0qW0V9rY43zvgkPQm8}]
查询返回正确的文档ID。但是,这些文档的数据为空,但是,在Firestore控制台中,每个相应的文档都有许多带有数据的字段(名称,等级,地址等)。

这是预料之中的,因为您仅获取快照。您需要在每个文档上运行data()函数以获取其数据:
query.get().then((value) => {
// All GeoDocument returned by GeoQuery, like the GeoDocument added above
for (const doc of value.docs) {
console.log(doc.data());
}
