尝试将 google 云函数与 node.js 一起使用时,admin.firestore 不是函数

admin.firestore is not a function when trying to use google cloud functions with node.js

这是 node.js index.js 文件的 header:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var db = admin.firestore();

这是监听 firestore 变化的 node.js 函数:

exports.myFoo = functions.firestore
  .document('foo/{bar}')
  .onWrite(event => {
    // do stuff
}

这在 package.json 文件中:

  "dependencies": {
    "firebase-admin": "^5-.4.2",
    "firebase-functions": "^0.7.1",
    "firestore": "^1.1.6"
  },

当我尝试执行“firebase 部署”命令时,这是我收到的错误:

Error: Error occurred while parsing your function triggers.
TypeError: admin.firestore is not a function

问Firebase

我能够重现错误并暴力破解解决方案。我对 npm 了解不多,无法完整解释此解决方案为何有效。

我的原文package.json包含:

  "dependencies": {
    ...
    "firebase-admin": "^4.2.1",
    "firebase-functions": "^0.7.1",
    ...
  },

作为recommended in the documentation,我运行函数文件夹中的这两个命令:

npm install -g firebase-tools
npm install firebase-functions@latest --save

我也试过:

npm install --save firebase-admin
npm upgrade

我反复收到这些错误消息:

+-- UNMET PEER DEPENDENCY firebase-admin@4.2.1
npm WARN firebase-functions@0.7.1 requires a peer of firebase-admin@~5.4.2 but none was installed.

我认为 firebase-admin 需要更新,但无法实现。所以我编辑了依赖文件以删除这一行:

"firebase-admin": "^4.2.1"

然后 运行 再 npm install --save firebase-admin。这样,package.json 包含版本 "firebase-admin": "^5.4.2"var db = admin.firestore(); 编译没有错误。

在你的file.js(异步方法)中解决:

const getFirestore = () => admin.firestore()

例如:

 getFirestore()
  .collection(`mailchimp-users`)
  .doc(uid)
    .set(profile)
      .then(() => res.redirect(MAILCHIMP_AUTH_SUCCESS_URL))
      .catch((error) => res.json({error}))

functions.firestore 应该是 functions.firestore()

试试这个

const getReceiverDataPromise = admin.firestore().doc('users/' + receiverUID).get();
const getSenderDataPromise = admin.firestore().doc('users/' + senderUID).get();

return Promise.all([getReceiverDataPromise, getSenderDataPromise]).then(results => {

        const receiver = results[0].data();
        console.log("receiver: ", receiver);

        const sender = results[1].data();
        console.log("sender: ", sender);

    });
