错误：在 Heroku 上运行 sequelize db:migrate 时的自签名证书

标签： node.js postgresql heroku sequelize.js

我是一名计算机科学专业的学生，​​正在尝试构建他的第一个 Web 项目，但在 Heroku 上部署我的应用程序时遇到了问题，使用 Sequelize 迁移我的数据库更准确。 这个问题 ("Self signed certificate" error on Heroku running sequelize db:migrate) 正是我的情况，只是该帖子中给出的解决方案没有解决我的问题。我正在使用 Node.js、Express.js、Sequelize、Postgresql 和 Heroku。

总而言之，我的项目构建得很好，并且似乎也可以很好地运行“node server.js”，查看 Heroku 日志。但是，当我尝试运行“heroku run sequelize db:migrate”时，出现以下错误：

(base) ---@Jangui-MacBookAir adonde-ex % heroku run sequelize db:migrate 
Running sequelize db:migrate on ⬢ adonde-kr... up, run.1405 (Free)

Loaded configuration file "config/config.js".
Using environment "production".

**ERROR: self signed certificate**

下面是日志，以防这些知识有所帮助（包括一些控制台日志）：

Server.js 是我设置端口的地方，我有一个模型文件夹，我保存所有模型构建、数据库相关代码。在models/index.js中，我初始化了一个Sequelize实例并连接到db。

models/index.js

'use strict';

if (process.env.NODE_ENV !== 'production') require('dotenv').config();

const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname + '/../config/config.js')[env];
const db = {};

console.log("process.env[config.use_env_variable]: ", process.env[config.use_env_variable]);
console.log("config.use_env_variable: ", config.use_env_variable)
console.log("process.env.DATABASE_URL: ", process.env.DATABASE_URL)
console.log("config: ", config);

let sequelize;
if (config.use_env_variable) {
  console.log("there exists use_env_variable")
  sequelize = new Sequelize(process.env[config.use_env_variable], {
    dialect: "postgres",
    dialectOptions: {
      ssl: {
        // Ref.: https://github.com/brianc/node-postgres/issues/2009
        rejectUnauthorized: false,
      },      
    },
  });
} else {
  sequelize = new Sequelize(config.database, config.username, config.password, config);
}

// let sequelize;
// sequelize = new Sequelize(
//   config.database,
//   config.username,
//   config.password,

fs
  .readdirSync(__dirname)
  .filter(file => {
    return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
  })
  .forEach(file => {
    const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
    db[model.name] = model;
  });

Object.keys(db).forEach(modelName => {
  if (db[modelName].associate) {
    db[modelName].associate(db);
  }

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

我已经尝试解决此问题大约 两天，任何输入都将不胜感激。 请帮忙！

检查您的 config.js 文件。 你有一个错字。将 rejectUnautorized 更正为 rejectUnauthorized 那应该这样做。 最好的问候并保持安全。
