node.js - 通过flutter中的节点js文件将firebase与我的项目链接时出现错误

问题描述

我的“日志”部分中的一个匿名错误出现在 firebase 项目上，而 Android Studio 中的“运行”中没有显示任何错误。我对node js一无所知，我只是想通过它链接我的应用程序，这就是我被迫使用它的原因，有人可以帮助我吗？这是firebase项目的完整错误->函数->日志

srv/node_modules/@google-cloud/firestore/build/src/collection-group.js:54
    async *getPartitions(desiredPartitionCount) {
          ^

SyntaxError: Unexpected token *
    at createScript (vm.js:80:10)
    at Object.runInThisContext (vm.js:139:10)
    at Module._compile (module.js:617:28)
    at Object.Module._extensions..js (module.js:664:10)
    at Module.load (module.js:566:32)
    at tryModuleLoad (module.js:506:12)
    at Function.Module._load (module.js:498:3)
    at Module.require (module.js:597:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (/srv/node_modules/@google-cloud/firestore/build/src/index.js:39:28)

这是firebase项目->函数->日志的第二个错误。：

Error detected in onCreateFollower {"errorEvent":{"eventTime":"2020-10-31T06:41:42.682Z","message":"/srv/node_modules/@google-cloud/firestore/build/src/collection-group.js:54\n    async *getPartitions(desiredPartitionCount) {\n          ^\n\nSyntaxError: Unexpected token *\n    at createScript (vm.js:80:10)\n    at Object.runInThisContext (vm.js:139:10)\n    at Module._compile (module.js:617:28)\n    at Object.Module._extensions..js (module.js:664:10)\n    at Module.load (module.js:566:32)\n    at tryModuleLoad (module.js:506:12)\n    at Function.Module._load (module.js:498:3)\n    at Module.require (module.js:597:17)\n    at require (internal/module.js:11:18)\n    at Object.<anonymous> (/srv/node_modules/@google-cloud/firestore/build/src/index.js:39:28)","serviceContext":{"service":"onCreateFollower","resourceType":"cloud_function"}},"@type":"type.googleapis.com/google.devtools.clouderrorreporting.v1beta1.Insight","errorGroup":"COvaxM_ErLfhbg"

这是 Android Studio 中 index.js 文件中的代码 -

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
//   functions.logger.info("Hello logs!", {structuredData: true});
//   response.send("Hello from Firebase!");
// });

exports.onCreateFollower = functions.firestore.document("/followers/{userId}/userFollowers/{followerId}").onCreate(async (snapshot, context) => {
  console.log('Follower Created', snapshot.id);
  const userId = context.params.userId;
  const followerId = context.params.followerId;
  const followedUserPostsRef = admin.firestore().collection('posts').doc(userId).collection('userPosts');
  const timelinePostsRef = admin.firestore().collection('timeline').doc(followerId).collection('timelinePosts');
  const querySnapshot = await followedUserPostsRef.get();
  querySnapshot.forEach(doc => {
    if(doc.exists) {
       const postId = doc.id;
       const postData = doc.data();
       timelinePostsRef.doc(postId).set(postData);
    }
  })
});

解决方案

将 firebase-admin 的版本更改为“firebase-admin”：“^ 8.10.0”，将 firebase-functions 更改为“firebase-functions”：“^ 3.6.1”。我也遇到了这个问题并解决了。
