错误：“无法连接到 MongoDB Atlas 集群中的任何服务器”

Question

错误：“无法连接到 MongoDB Atlas 集群中的任何服务器”

我的节点应用程序给我这条消息“无法连接到您的 MongoDB Atlas 集群中的任何服务器。确保您当前的 IP 地址在您的 Atlas 集群的 IP 白名单中”。

我已经在 IP 白名单上添加了我当前的 IP 地址以及 0.0.0.0。

下面是错误消息的图片和我为连接它而编写的代码。我是 node.js 和 mongodb 的新手。我查看了这里的所有解决方案，但没有一个能够解决这个问题。

var express = require('express');
var bodyparser = require('body-parser');
var mongoose = require('mongoose');

var app = express();
app.use(bodyparser.json());

mongoose
     .connect("mongodb+srv://<username:password>@my-cluster.mongodb.net/test?retryWrites=true&w=majority", 
     { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true })
     .then(() => console.log( 'Database Connected' ))
     .catch(err => console.log( err ));

    app.listen(3003)

尝试这样做：- MongoDB Atlas-> NetworkAccess-> Edit->Allow Any

这对我有用！

他已经提到他在 IP 白名单上设置了 0.0.0.0 （大概是 /0 ），这是你建议的结果。如果它对你有用，那么你就会遇到不同的问题。 (6认同)
“IP 访问列表”下的“允许任何”似乎不再是一个选项 (5认同)
是的，我当时不知道 0.0.0.0 是什么意思。但后来知道后，看到这个答案对人有帮助，所以就没有考虑删除。 (2认同)

a] click on delete 

ii] if you have not already added ip address, then just follow below steps:

4] click on add ip address
