连接到 Atlas MongoDB 时身份验证失败答案

【问题标题】：Authentication fail when connecting to Atlas MongoDB连接到 Atlas MongoDB 时身份验证失败

【问题描述】：

从旧 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:PASSWORD@cluster-3kcdl3j9.auof1.mongodb.net/heroku_3kcdl3j9?retryWrites=true&w=majority';

我已将我的数据库从 MLAB 迁移到 Atlas，成功地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，我仍然得到这个错误，我不知道我做错了什么：

【问题讨论】：

您的凭据错误或未正确转义，或者用户不存在。阅读服务器日志以了解它对这种情况的看法。

【解决方案1】：

关于从 MLAB 到 ATLAS 的迁移文档，我可以阅读：

Atlas 服务器始终使用 requireSSL 运行，并且只接受 TLS/SSL 加密连接。

我可以看到您的 ssl 选项已被注释。这是一个问题。

【讨论】：

我已尝试使用此选项，但没有任何区别......还改变了我现在连接的方式以使用 MongoClient，正如它在 Atlas 上所说的那样，这也没有修复它，我完全卡住了： const client = new MongoClient(mongoURI, { useNewUrlParser: true }, { options : { ssl: true } }); client.connect(err => {

【解决方案2】：

问题在于它与用户名和密码有关。我相信密码中有非法字符。所以我用更好的密码创建了另一个用户，服务器经过身份验证并登录允许它连接。
