Question

我已将我的IP列入白名单，并且已正确替换了URI字符串中的用户名和密码（包括密码中的特殊字符），但是它不起作用。我还尝试允许从任何地方进行访问，但是结果是相同的。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，花了几个小时，但无法解决此问题。有什么想法吗？

Answer 1

原来是我的密码引起了问题。我选择了带有一些特殊字符的代码，即使我遵循instructions in the documentation进行编码的方式，但还是无法正常工作。我终止了群集，并使用不包含特殊字符的密码创建了一个群集，它可以正常工作。

Answer 2

请检查您的连接凭据字符串的格式设置是否正确，以便它包含HTML代码，而不仅仅是文本，即％24。

这是我前一段时间使用的示例。另外，我在无法找到测试数据库的地方遇到了一个错误，因此也要在URI中进行更改。

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