node.js - 无法使用 Sequelize 连接到 GCP Postgres 数据库

Question

我在 GCP 中创建了一个数据库，但是当我尝试将它与本地主机上的 Node.js 服务器连接时，出现以下错误:

    original: Error: connect ETIMEDOUT 35.202.153.108:5432
      at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1146:16) {
    errno: -4039,
    code: 'ETIMEDOUT',
    syscall: 'connect',
    address: '35.202.153.108',
    port: 5432
  }

这是我在 db.js 中的代码:

const { Sequelize } = require('sequelize');
const sequelize = new Sequelize(
  process.env.DATABASE_NAME,
  process.env.DATABASE_USERNAME,
  process.env.DATABASE_PASSWORD,
  {
    host: process.env.DATABASE_HOST,//35.202.153.108
    dialect: 'postgres',
  }
);

module.exports = sequelize;


db.authenticate()
  .then((t) => console.log('Connection has been established successfully.'))
  .catch((error) => console.error('Unable to connect to the database:', error));

有人可以帮助我连接到 GCP 数据库吗？

试试这个:
Create a TCP connection by using Node.js

const createTcpPool = config => {
  // Extract host and port from socket address
  const dbSocketAddr = process.env.DB_HOST.split(':'); // e.g. '127.0.0.1:5432'

  // Establish a connection to the database
  return Knex({
    client: 'pg',
    connection: {
      user: process.env.DB_USER, // e.g. 'my-user'
      password: process.env.DB_PASS, // e.g. 'my-user-password'
      database: process.env.DB_NAME, // e.g. 'my-database'
      host: dbSocketAddr[0], // e.g. '127.0.0.1'
      port: dbSocketAddr[1], // e.g. '5432'
    },
    // ... Specify additional properties here.
    ...config,
  });
};
