我正在尝试使用 geofirestore 执行GeoQuery。我想获取给定集合中 1000 半径内的所有文档。
这是我的 .js 文件:
const GeoFirestore = require('geofirestore').GeoFirestore;
const GeoPoint = require('geopoint');
const firebase = require('firebase');
firebase.initializeApp({
projectId : 'my-project-id'
});
module.exports = {
getLocalDocuments: getLocalDocuments
}
async function getLocalDocuments() {
let latitude = 38.9537323;
let longitude = -77.3507578;
let radius = 1000;
// Create a Firestore reference
const firestore = firebase.firestore();
// Create a GeoFirestore reference
const geofirestore = new GeoFirestore(firestore);
// Create a GeoCollection reference
const geocollection = geofirestore.collection('myDocs');
const query = geocollection.near({
center: new GeoPoint(latitude, longitude),
radius
});
// Get query (as Promise)
await query.get().then((value) => {
console.log(`value.docs: ${value.docs}`); // All docs returned by GeoQuery
});
}
调用getLocalDocuments()函数时,我得到以下堆栈跟踪:
Error: Invalid location: latitude must be a number

这是validateLocation方法:
function validateLocation(location, flag) {
if (flag === void 0) { flag = false; }
var error;
if (!location) {
error = 'GeoPoint must exist';
}
else if (typeof location.latitude === 'undefined') {
error = 'latitude must exist on GeoPoint';
}
else if (typeof location.longitude === 'undefined') {
error = 'longitude must exist on GeoPoint';
}
else {
var latitude = location.latitude;
var longitude = location.longitude;
if (typeof latitude !== 'number' || isNaN(latitude)) {
error = 'latitude must be a number';
}
else if (latitude < -90 || latitude > 90) {
error = 'latitude must be within the range [-90, 90]';
}
else if (typeof longitude !== 'number' || isNaN(longitude)) {
error = 'longitude must be a number';
}
else if (longitude < -180 || longitude > 180) {
error = 'longitude must be within the range [-180, 180]';
}
}
if (typeof error !== 'undefined' && !flag) {
throw new Error('Invalid location: ' + error);
}
else {
return !error;
}
}
知道为什么说纬度不是数字吗?我检查了 isNaN() 和其他方法,他们都说这是一个数字。
