[英]CosmosDB Geospatial query returns nothing
我正在使用MongoDB界面瀏覽Azure的CosmosDB。 我編寫了以下測試(使用Jest)。 我的大多數其他測試都可以將MongoDB url交換為CosmosDB url,它們將運行並通過。 指向MongoDB時,此測試通過,但CosmosDB url失敗:
const { MongoClient } = require('mongodb')
let client, db, collection
const url = 'mongodb://localhost:27017'
const dbName = 'test'
describe('talking to mongodb', () => {
beforeEach(async () => {
client = await MongoClient.connect(url)
db = client.db(dbName)
collection = db.collection('cities')
await collection.createIndex({ location: '2dsphere' })
})
afterEach(async () => {
await collection.drop()
client.close()
})
it('it can find geocoded things', async () => {
await collection.insertMany([
{
city: 'Ottawa, Canada',
location: {
type: 'Point',
coordinates: [-75.69719309999999, 45.4215296],
},
bbox: [-76.35391589999999, 44.962733, -75.2465979, 45.5375801],
},
{
city: 'Moscow, Russia',
location: { type: 'Point', coordinates: [37.6172999, 55.755826] },
bbox: [37.3193289, 55.48992699999999, 37.9456611, 56.009657],
},
])
let cursor = await collection.find({
location: {
$near: { type: 'Point', coordinates: [-79.3831843, 43.653226] },
$maxDistance: 500000,
},
})
let [doc] = await cursor.toArray()
expect(doc.city).toEqual('Ottawa, Canada')
})
})
該測試失敗,並出現以下錯誤:
● talking to mongodb › it can find geocoded things
MongoError: Request is malformed
at node_modules/mongodb-core/lib/cursor.js:769:34
at handleCallback (node_modules/mongodb-core/lib/cursor.js:178:5)
at setCursorDeadAndNotified (node_modules/mongodb-core/lib/cursor.js:545:3)

at queryCallback (node_modules/mongodb-core/lib/cursor.js:263:5)
at node_modules/mongodb-core/lib/connection/pool.js:542:18
請記住,該查詢在MongoDB中有效。 稍作修改,我就能得到一個在MongoDB中工作的查詢,並且不會在CosmosDB中產生錯誤:
db.cities.find({"location": { $near:{ $geometry: { type: "Point", coordinates: [-79.3831843, 43.653226] }, $maxDistance: 500000 }}})
但是,該查詢在CosmosDB上不返回任何內容。
我需要怎么做才能使查詢返回結果並通過CosmosDB進行測試?
