Mongoose 无法在没有 Internet 的情况下连接 [英] Mongoose Can't Connect Without Internet

问题描述

我的 MongoDB 服务器在 localhost:27017 上运行，虽然我通常可以正常运行我的 Node.js 应用程序，但当我断开互联网连接时 Mongoose 会抛出错误

I have my MongoDB server running on localhost:27017, and while I can usually run my Node.js app fine, when I disconnect from the internet Mongoose throws the error

Error: failed to connect to [localhost:27017]

请注意，我仍然可以从 Mongo shell 客户端连接到 MongoDB 服务器.此外，如果我先启动我的应用程序然后失去互联网连接，我的应用程序可以很好地离线访问数据库.那么为什么它不能在没有互联网的情况下启动?

Note that I can still connect to the MongoDB server from the Mongo shell client. Also, if I start up my app first and then lose internet connection, my app can access the database fine offline. So why can't it start up without internet?

这里是完整的错误

events.js:85
      throw er; // Unhandled 'error' event
            ^

措辞

推荐答案

使用 127.0.0.1 而不是 localhost.通过关闭您的 wifi 接口，操作系统不再能够解析本地主机.

Use 127.0.0.1 instead of localhost. By turning off your wifi interface the OS is no longer able to resolve localhost.
