无法使用node.js向MongoDB进行身份验证

Question

I've been attempting to add authentication to my mongo database.

So following various tutorials and solving some problems (my server was 2.4 and needed to be upgraded), I was finally able to add a user

I run the server in one shell

mongod --dbpath ./

then in another I run

mongo
use admin
db.createUser({
     user:"user",
     pwd:"pass",
     roles: [{role:"userAdminAnyDatabase", db:"admin"}]
})

I get a success message, so then I quit out of both the server and the shell

In another shell I run

mongod --dbpath ./ --auth

Then I run

node server.js

Within the server.js file, there is the following code

mongodb.MongoClient.connect('mongodb://127.0.0.1:27017/db', function(err, db) {
    if(err) throw err;  
    db.authenticate("user", "pass", function(err, res) {
        if(err) throw err;      
        // code here
    });
});

But this throws a mongo error, that authentication failed

Am I trying to authenticate incorrectly, or doing something else wrong? I'm not understanding my mistake.

Here is the error

Answer 1

看来您是在名为admin的数据库中创建用户，然后尝试登录名为db 。

Answer 2

It fails when you pass in the db to connect to in the url. Looks like the authentication is done against the same db. Instead you should do:

    const client = await new Promise((res, rej) =>
      MongoClient.connect(
        K2_MONGODB_URL,
        {
          auth: {
            authdb: 'admin'
          },
          useNewUrlParser: true 
        },
        (err, client) => (err ? rej(err) : res(client))
      )
    )

where K2_MONGODB_URL=mongodb://user:password@localhost:27017
