Question

当前，我正在使用Firebase Function作为我正在使用的应用程序的node.js后端。我也使用Sequalize ORM与MySQL数据库连接。在两个或两个以上的星期中，它完全可以正常工作，但是现在每次我甚至尝试启动应用程序时，都会出现此错误：SequelizeConnectionError：连接ETIMEDOUT。

Unable to connect to the database: { SequelizeConnectionError: connect ETIMEDOUT

具有Sequelize连接的Index.js的定义如下：

// Dependecies
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');

// App init
const app = express();

// Database Init
const db = require('./configs/db')
db.authenticate()
.then(() => console.log('Connection has been established successfully.'))
.catch(err => console.error('Unable to connect to the database:', err));

// CORS Middleware
app.use(cors());

// Routes
const lists = require('./routes/lists.js');
const tombs = require('./routes/tombs.js');
const doors = require('./routes/doors.js');
const fullTextSearches = require('./routes/ftSearch.js');
const lytics = require('./routes/lytics.js');

// BodyParser Middlware
app.use(bodyParser.json({
  limit: '50mb'
}));

// Routes use
app.get('/api/test', (req, res) => res.send('Api is working!'));

app.use('/api/tombs/', tombs);
app.use('/api/doors/', doors);
app.use('/api/ftsearch/', fullTextSearches);
app.use('/api/lytics/', lytics);
app.use('/api/lists/', lists);

// ------------------------
// Function export
// ------------------------
exports.main = functions.https.onRequest(app);

和configs / db.js

const db = new Sequelize('db', 'user', 'passwd', {
  host: 'host',
  dialect: 'mysql',
  pool: {
      max: 1,
      min: 0,
      acquire: 30000,
      idle: 10000
  },
  operatorsAliases: false,
  logging: false
});

module.exports = db;

我正在使用的MySQL服务器是一种共享托管服务。应用程序前端托管在Firebase托管中。当我使用Firebase CLI运行相同的应用程序时，连接非常好。问题只有在我部署它时才会发生。帐单帐户似乎有问题，但我有Blaze计划，尚未超出任何限制。与this question中的问题基本上相同，但是没有答案，至少有一个可以解决我的问题。

更改池大小根本没有帮助。我能够找到的任何其他答案都表明这是Spark计划的问题，但是我使用的是Blaze，所以我现在有点迷路了...
