Question

我遇到一个问题，试图解决很长时间。我尝试使用mongoose npm从nodejs连接到mongo atlas云。现在，这不是我的第一次，但是我只是找不到答案

我的猫鼬版本：5.9.22

这是我的代码：

  const express = require('express')
    const mongoose = require('mongoose')
    const bodyparser = require('body-parser')
    
    const app = express()
    app.use(bodyparser.json())
    
  mongoose.connect("mongodb+srv://dudvil1:password@cluster0.guxmm.mongodb.net/shopping_list? 
  retryWrites=true&w=majority", {
      useNewUrlParser: true,
      useUnifiedTopology: true
  })
          useNewUrlParser: true,
          useUnifiedTopology: true
      })
      .then(() => console.log('mongo connected'))
       .catch(err => console.log(err));   
    
    const port = process.env.PORT || 5000   
    
    app.listen(port, () => console.log(`server started in port ${port}`))

我的白名单仅包含0.0.0.0/0 我在数据库acsses中的用户名和密码非常简单，没有任何特殊字符但总是会得到相同的错误：

Answer 1

您可以尝试以下步骤：

单击网络访问。

单击删除按钮旁边的编辑按钮。
单击“添加当前IP地址”按钮，然后单击“确认”。

这样，您将可以从任何IP地址访问数据库。

让我知道它是否对您有用：）

Answer 2

使用当前 IP 地址 1）进入mongodb上的网络访问 2)选择当前IP地址

错误：“无法连接到MongoDB Atlas集群中的任何服务器”
