node.js - Node Postgres SequelizeConnectionError : password authentication failed for user

Question

我正在使用 node 和 sequelize 开发后端应用程序。我的数据库来自 postgresql。

启动应用程序时，数据库连接工作正常，但当它尝试与数据库通信以读取或更新时，它会失败并出现连接错误:
用户“wushin”的密码验证失败。

对我来说似乎真的很奇怪，因为数据库连接已经完成，并且密码已经过验证。你们知道发生了什么吗？可能是 pg 模块的问题，但我尝试了不同的版本。

版本
Node :10.17.0
Sequelize :5.21.3
Postgres:10.11
pg模块:7.17.1

-> 此代码工作正常:

const sequelize = new Sequelize(process.env.DATABASE_DEV_URL)

sequelize
  .authenticate()
  .then(() => {
    console.log('Connection has been established successfully.\n')
  })
  .catch(err => {
    console.error('Unable to connect to the database:', err)
  })

-> 但是这个 promise 因 SequelizeConnectionError 而失败:

models.Question.findAll()
    .then(data => {
      console.log('-> Succeeded data fetching\n')
      console.log(data)
    })
    .catch(err => {
      console.log('-> Failed data fetching\n')
      console.log('Error', err)
    })

日志:

yarn run v1.19.2
$ node index.js
Example app listening on port 4000 or something!
Executing (default): SELECT 1+1 AS result
Connection has been established successfully.

- Trying to fetch data:
-> Failed data fetching

您似乎没有将任何配置传递给 Sequelize但主人。最低配置是主机、端口、数据库名称、方言用户名和密码。

从文档:

 const Sequelize = require('sequelize');

 // Option 1: Passing parameters separately const sequelize = new
 Sequelize('database', 'username', 'password', {   
   host: 'localhost',  
   dialect: /* one of 'mysql' | 'mariadb' | 'postgres' | 'mssql' */ 
 });

// Option 2: Passing a connection URI const sequelize = new
 Sequelize('postgres://user:pass@example.com:5432/dbname');
