javascript - postgres 与 node.js 连接中的 SASL 错误

Question

尝试连接到我的数据库时出现以下错误:

Conexão estbabelecida com sucesso
Acessar http://localhost:3000
Servidor executando na porta 3000
C:\Users\lopes\Desktop\Javascript\novo-projeto\ExpressEWebpack\node_modules\pg\lib\sasl.js:24
    throw new Error('SASL: SCRAM-SERVER-FIRST-MESSAGE: client password must be a string')
    ^

[nodemon] app crashed - waiting for file changes before starting...

这是我的连接代码

require('dotenv').config();
const express = require('express');
const app = express(); 
const { Sequelize } = require('sequelize');
const sequelize = new Sequelize(process.env.DB_URL);

try {
    sequelize.authenticate();
    console.log('Conexão estbabelecida com sucesso')
}catch{
    console.log('Erro ao estabelecer conexão');
}

const session = require('express-session');
const flash = require('connect-flash');

const routes = require('./routes')
const path = require('path');


app.use(express.urlencoded({  extended:true }));

app.use(express.static(path.resolve(__dirname, 'public')));

const sessionOptions = session({
    secret:process.env.cookie_secret,
    store: new (require('connect-pg-simple')(session))(),
    resave: false,
    saveUninitialized: false,
    cookie: {maxAge: 1000 * 60 * 60 * 24 * 7}
});

app.use(sessionOptions);
app.use(flash());

app.set('views', path.resolve(__dirname, 'src', 'views'));
app.set('view engine', 'ejs');

app.use(routes);

app.listen(3000, () => {
    console.log('Acessar http://localhost:3000');
    console.log('Servidor executando na porta 3000');
});

我有这个错误，但我的数据库根本没有密码，我没有密码的事实可能会干扰连接？在某种程度上，密码因为没有值(value)而收到空值？我试图解决，看看 sasl.js 上有什么，但没有太大帮助

Answer 1

在您的 pg_hba.conf 文件(在 Windows 上，目录是\Program Files\PostgreSQL\13\data)将 IPv4 和 IPv6 本地连接的方法更改为 信任 . 急停-sha-256 加密机制需要一个密码，这就是它失败的原因。
