我的环境设置：

database.js

** server.js **

** response.js **

** 配置变量 **

网站在本地主机上运行良好，同时具有开发和生产环境。所以它连接到 Atlas 上的 MongoDB，没有问题。

我没有在 Heroku 上安装任何插件。

** packages.json **

Atlas这边我把所有的IP都开放白名单了

有什么想法吗？谢谢！ :)

Answer 1

将其设为您的 database.json

{
  "defaultConnection": "default",
  "connections": {
    "default": {
      "connector": "mongoose",
      "settings": {
        "client": "mongo",
        "host": "${process.env.DATABASE_HOST}",
        "port": "${process.env.DATABASE_PORT}",
        "database": "${process.env.DATABASE_NAME}",
        "username": "${process.env.DATABASE_USERNAME}",
        "password": "${process.env.DATABASE_PASSWORD}",
      },
      "options": {}
    }
  }
}

还要确保将 package-lock.json 添加到您的 git.ignore 文件中。然后做

git add .
git commit -m "(message) "
git push heroku master

然后

heroku open 也启动您的应用服务器

Answer 2

我在 Heroku 上部署 Strapi 3.0.1 的配置，包括开发和生产环境：

module.exports = ({ env }) => ({
  defaultConnection: "default",
  connections: {
    default: {
      connector: "mongoose",
      settings: {
        uri: env("DATABASE_URI"),
        ssl: { rejectUnauthorized: false }
      },
      options: {
        ssl: true,
        authenticationDatabase: "",
        useUnifiedTopology: true,
        pool: {
          min: 0,
          max: 10,
          idleTimeoutMillis: 30000,
          createTimeoutMillis: 30000,
          acquireTimeoutMillis: 30000
        }
      },
    },
  },
});

server.js

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 443), <-- 443 was critical to make it work on production
});

.env - 本地文件

DATABASE_URI="mongodb+srv://OdegXXXXXUser:OXXXX20@odXXXXcluster-h9o2e.mongodb.net/odeXXXXXndb?retryWrites=true&w=majority"
HOST="0.0.0.0"
PORT="1337"

Heroku 上的变量：

DATABASE_URI 呃，与本地主机相同，数据库相同。

希望对大家有所帮助:-)
