Mongoose connect to authentication db语法包括auth和useNewUrlParser选项

Question

我正在尝试本地连接到身份验证数据库以访问我的应用数据库。如果我包括useNewUrlParser:true选项，它会破坏整个过程，导致身份验证失败。删除useNewUrlParser选项会连接，但不会勾选此选项：

config = {
    database: "mongodb://localhost:27017/authapp",
    auth: {
        user : "admin",
        password : "123456",
        authdb : "admin"
    }

...

mongoose
  .connect(config.database, { 
        auth: config.auth,
        useNewUrlParser: true 
    })
  .then(() => {...}

我得到：

我是否缺少一种模式，或者什么样的方式适用于这种情况？我还尝试了数据库连接字符串中的用户pw，但它也没有按预期连接-可能缺少身份验证数据库名称？

希望有人能为我指出这个简单问题的正确方向。

使用authSource而不是authdb

 auth:{
     user: "admin",
     password: "123456",
     authSource: "admin",                                 
    },
