Firebase Cloud Functions 上的函数不 appear/run

Question

我可以按照视频指南成功部署 HelloWord 应用程序 here。

但现在我按照说明 here 来 link Algolia 和 Firebase with Cloud Functions，我可以运行我电脑上的代码并更新，但不知何故当我在 Firebase 上进行更改时它不会自动更新。

其次，当我部署应用程序时，我收到 "deploy complete" 消息，但 Firebase 中没有显示任何内容>>功能，并且当我对 Firebase 进行更改时，Algolia 没有更新。

index.js代码

const algoliasearch = require('algoliasearch');
const dotenv = require('dotenv');
const firebase = require('firebase');

// load values from the .env file in this directory into process.env
dotenv.load();

// configure firebase
firebase.initializeApp({
  databaseURL: process.env.FIREBASE_DATABASE_URL,
});
const database = firebase.database();

// configure algolia
const algolia = algoliasearch(
  process.env.ALGOLIA_APP_ID,
  process.env.ALGOLIA_API_KEY
);
const index = algolia.initIndex(process.env.ALGOLIA_INDEX_NAME);

//synchronize firebase database with algolia index
const contactsRef = database.ref('/contactDetail/botswana');
contactsRef.on('child_added', addOrUpdateIndexRecord);
contactsRef.on('child_changed', addOrUpdateIndexRecord);
contactsRef.on('child_removed', deleteIndexRecord);

function addOrUpdateIndexRecord(contact) {
  // Get Firebase object
  const record = contact.val();
  // Specify Algolia's objectID using the Firebase object key
  record.objectID = contact.key;
  // Add or update object
  index
    .saveObject(record)
    .then(() => {
      console.log('Firebase object indexed in Algolia', record.objectID);
    })
    .catch(error => {
      console.error('Error when indexing contact into Algolia', error);
      process.exit(1);
    });
}

function deleteIndexRecord(contact) {
  // Get Algolia's objectID from the Firebase object key
  const objectID = contact.key;
  // Remove the object from Algolia
  index
    .deleteObject(objectID)
    .then(() => {
      console.log('Firebase object deleted from Algolia', objectID);
    })
    .catch(error => {
      console.error('Error when deleting contact from Algolia', error);
      process.exit(1);
    });
}

package.json代码

  "name": "functions",
  "description": "Cloud Functions for Firebase",

Answer 1

您是否检查了 Functions 部分中的日志？为了看到 Algolia 中的变化，您应该首先看到该函数出现在您的 firebase 控制台中。

Answer 2

在代码运行之前，我不得不对其进行一些更改

函数需要使用 "exports"
函数不使用 .on() 作为侦听器，而是使用例如onCreate() 有一个参数，更多here。见下文

exports.childAdded=contactsRef.onCreate(addOrUpdateIndexRecord);

解决方案：

const algoliasearch = require('algoliasearch');
const dotenv = require('dotenv');
const functions = require('firebase-functions');

// load values from the .env file in this directory into process.env
dotenv.load();

// configure algolia
const algolia = algoliasearch(
  process.env.ALGOLIA_APP_ID,
  process.env.ALGOLIA_API_KEY
);
const index = algolia.initIndex(process.env.ALGOLIA_INDEX_NAME);

//synchronize firebase database with algolia index
const contactsRef = functions.database.ref('/contactDetail/locationA/{contactID}');

exports.childAdded=contactsRef.onCreate(addOrUpdateIndexRecord);
exports.childChanged=contactsRef.onUpdate(addOrUpdateIndexRecord); 
exports.childRemoved=contactsRef.onDelete(deleteIndexRecord);

function addOrUpdateIndexRecord(contact) {
  console.log("The function addOrUpdateIndexRecord is running!");
  // Get Firebase object
  const record = contact.data.val(); 
  
  // Specify Algolia's objectID using the Firebase object key
  record.objectID = contact.data.key;
  // Add or update object
  return index 
    .saveObject(record)
    .then(() => {
      console.log('Firebase object indexed in Algolia', record.objectID);
    })
    .catch(error => {
      console.error('Error when indexing contact into Algolia', error);
      process.exit(1);
    });      
}

function deleteIndexRecord(contact) {
  // Get Algolia's objectID from the Firebase object key
  const objectID = contact.data.key; 
  // Remove the object from Algolia
  return index
    .deleteObject(objectID)
    .then(() => {
      console.log('Firebase object deleted from Algolia', objectID);
    })
    .catch(error => {
      console.error('Error when deleting contact from Algolia', error);
      process.exit(1);
    });
}

Firebase Cloud Functions 上的函数不 appear/run
