functions/index.js:
const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp(functions.config().firebase)
const db = admin.database().ref()
exports.app = functions.https.onRequest((req, res) => {
// do whatever here...
db.child('something').once('value').then(snap => console.log(snap.key))
})
上面适用于firebase。
我有兴趣使此示例从功能中起作用。像这样但有效的东西:
const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp(functions.config().firebase)
const db = admin.database().ref()
exports.request = functions.https.onRequest((req, res) => {
let docRef = db.collection("cities").doc("SF")
docRef.get().then(doc => {
if (doc.exists) console.log("Document data:", doc.data())
else console.log("No such document!")
}).catch(error => {
console.log("Error getting document:", error)
})
})
使用admin.firestore()
代替admin.database()
。确保您的firebase-admin模块为5.4.1或更高。
exports.fun = functions.https.onRequest((req, res) => {
const store = admin.firestore()
store.collection('users').doc('foo').get().then(doc => {
if (doc.exists) {
console.log(doc.data())
res.send(doc.data())
}
else {
res.send("Nothing")
}
}).catch(reason => {
console.log(reason)
res.send(reason)
})
})
