node.js - 为什么 MongoDB 无法连接到我的 NodeJS 应用程序？

Question

在 nodejs 服务器中，mongodb 未连接。终端显示的错误代码

[nodemon] restarting due to changes...
[nodemon] starting `node app.js`
Server started on port 5000
MongoParseError: URI does not have hostname, domain name and tld

  [Symbol(mongoErrorContextSymbol)]: {}

这是连接代码

dbPassword = 'mongodb+srv://sayeed:'+ encodeURIComponent('123456') + 'mongodb://localhost:27017/node-passport-login';

module.exports = {
    mongoURI: dbPassword
};

完整的 nodejs 应用程序取自 Traversy Media 的 github 页面 Node Passport Login。

我也遇到过这个问题，我使用自动生成密码更新了我的密码，它对我有用。

EXAMPLE

If your password in plain-text is p@ssw0rd'9'!, you would need to encode your password as:

p%40ssw0rd%279%27%21
