连接到Atlas MongoDB时身份验证失败

问题描述

从旧的MLAB迁移数据后，连接到MongoDB Atlas数据库时出现错误。

我确实按照文档中的说明正确设置了用户名和密码（显然，我用正确的MLAB密码替换了PASSWORD：

var mongoURI = 'mongodb+srv://heroku_3kcdl3j9:[e-mail]/heroku_3kcdl3j9?retryWrites=true&w=majority';

我已将数据库从MLAB迁移到Atlas，已成功将正确的网络访问设置设置为0.0.0.0 IP地址。在Heroku中设置环境变量。

我使用此代码连接到Atlas数据库，是否需要一些特殊选项？ （此代码适用于旧的MLAB连接）

mongoose.connect(mongoURI,// { config: { autoIndex: true } },// { options : { ssl: true } },function (error) {
    if (error) console.error(error);
    else console.log('mongo connected');

     const con = new mongoose.mongo.Admin(mongoose.connection.db)
        con.buildInfo( (err,mongoURI) => {
        if(err){
          throw err
        }
       // see the db version
        // console.log('mongo db.version():  '+ db.version);
      })
});

但是，我仍然会收到此错误，我不知道自己在做什么错：

解决方法

关于从MLAB到ATLAS的迁移文档，我可以阅读：

Atlas服务器始终以requireSSL运行，并且仅接受TLS / SSL加密的连接。

我可以看到您的ssl选项已被注释。 这是一个问题。

,

问题在于这与用户名和密码有关。我相信密码中包含非法字符。因此，我创建了另一个具有更好密码的用户，并对服务器进行了身份验证并登录并允许其连接。
