SequelizeConnectionError：自签名证书

Question

我正在尝试连接到我在 Heroku 中设置的 PostgreSQL 数据库。

const { Sequelize, DataTypes, Model } = require("sequelize");

// DB Configuration
const sequelize = new Sequelize({
  database: "[wont'd show db]",
  username: "[won't show username]",
  password: "[won't show password]",
  host: "ec2-54-221-195-148.compute-1.amazonaws.com",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: true,
  },
});

这就是我得到的输出：

SequelizeConnectionError：自签名证书

Answer 1

这是由于node-postgres版本 8 中的（意外）重大更改（请参阅此 GitHub 问题）。

解决方案是传递rejectUnauthorized: false给sequelize连接参数，如GitHub 用户 jsanta 所述：

const sequelize = new Sequelize({
  database: "[wont'd show db]",
  username: "[won't show username]",
  password: "[won't show password]",
  host: "ec2-54-221-195-148.compute-1.amazonaws.com",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: {
      require: true,
      rejectUnauthorized: false // <<<<<<< YOU NEED THIS
    }
  },
});

Answer 2

就我而言，上述方法都不起作用，我使用连接字符串方法来应用 pg 配置，所以我设置了查询参数，sslmode=no-verify并且它起作用了

例子

postgres://myuser:mypassword@myhost:5432/mydatabasename?sslmode=no-verify
