javascript - SequelizeConnectionError : self signed certificate

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: self signed certificate

Answer 1

这是由于 node-postgres 中的(意外)重大更改。版本 8(见 this GitHub issue)。
解决办法是通过rejectUnauthorized: false到sequelize dialectOptions 内的连接参数> ssl ，如 described here by GitHub user jsanta :

const sequelize = new Sequelize({
  database: "xxxxx",
  username: "xxxxx",
  password: "xxxxx",
  host: "xxxxx",
  port: 5432,
  dialect: "postgres",
  dialectOptions: {
    ssl: {
      require: true,
      rejectUnauthorized: false // <<<<<<< YOU NEED THIS
    }
  },
});
