无法将猫鼬连接到 Atlas-MongoDB

Question

我已将我的IP列入白名单，并且我已正确替换URI字符串中的用户名和密码（包括密码中的特殊字符），但它不起作用。我也试过允许从任何地方访问，但结果是一样的。我收到此错误：

Server running on port 5000

    commonWireVersion: null
  },
  [Symbol(mongoErrorContextSymbol)]: {}
}

这是我的代码：

require("dotenv").config();
const express = require('express');
const mongoose = require('mongoose');

const port =  5000;
const ATLAS_URI = process.env.ATLAS_URI;
const app = express();

app.use(express.json());

mongoose.connect(ATLAS_URI, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useUnifiedTopology: true
   })
  .then(() => console.log('mongoDB connected'))
  .catch(err => console.log(err));

  app.listen(port, () => console.log(`Server running on port ${port}`));

我看过帖子，看过视频，也花了几个小时，但我无法解决这个问题。有什么想法吗？

Answer 1

检查您的连接凭据字符串的格式是否正确，因此它包含 HTML 代码而不只是文本，即 %24。

这是我不久前用过的一个例子。我也有一个错误，它找不到测试数据库，所以也改变了 URI 中的那个。

mongodb+srv://USERNAME:PASSWORD@cluster0-feebe.mongodb.net/DATABASE_NAME?retryWrites=true&w=majority

Answer 2

原来是我的密码导致了这个问题。我选择了一个带有一些特殊字符的字符，尽管我遵循 instructions in the documentation 如何对它们进行编码，但不知何故它不起作用。我终止了集群，使用不包含特殊字符的密码创建了一个集群，并且成功了。
