我正在尝试在 Heroku 上部署非常简单的 Nodejs API，但我似乎无法弄清楚为什么它一直给我这个错误。该应用程序在本地服务器上运行良好，即使使用heroku local web. 我的应用正在监听app.listen( process.env.PORT || 5500 );.

这是我的错误 heroku logs --tail。

使用以下代码进行连接 -

mongoose.connect(uri, {
      useNewUrlParser: true,
      useCreateIndex: true,
      useUnifiedTopology: true
    }).then(res=>{
            console.log("DB Connected!")
    }).catch(err => {
      console.log(Error, err.message);
    })

如果使用上面的代码
- 您需要将 Heroku IP 地址 b 列入 MongoDB Atlas 的白名单。
要添加的 IP 地址是 - '0.0.0.0/0'
