云函数错误:TypeError:db.collection不是函数

Question

当试图将数据发送到firestore时，您将返回此错误：

TypeError: db.collection is not a function
at FirestoreHelper.updateDocument (/workspace/node_modules/firebase-functions-helper/dist/firestore.js:7:56)
at app.patch (/workspace/lib/index.js:20:40)

我的索引.ts

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
import * as firebaseHelper from 'firebase-functions-helper/dist';
import * as express from 'express';
import * as bodyParser from 'body-parser';
admin.initializeApp(functions.config().firebase);
const db = admin.firestore;
const app = express();
const main = express();
main.use(bodyParser.json());
main.use(bodyParser.urlencoded({extended: false}));
main.use('/api/v1', app);
const trackerCollection = 'tracker';
export const webApi = functions.https.onRequest(main);
app.patch('/trackers/:trackerId', async(req, res) => {
try {
await firebaseHelper.firestore.updateDocument(db, trackerCollection, req.params.trackerId, req.body);
res.status(200).send('Update Success');
} catch (error) {
console.log(error);
res.status(204).send('Patch Error');
}
})

我正在为邮递员试镜。api url为：https://myapp/api/v1/trackers/12345678

状态邮递员=204

您需要进行

const db = admin.firestore();

而不是

const db = admin.firestore;

请注意，由于Firebase SDK for Cloud Functions的1.0.0版本，firebase-admin应在没有任何参数的情况下进行初始化，请参阅https://firebase.google.com/docs/functions/beta-v1-diff#new_initialization_syntax_for_firebase-管理员。
