猫鼬中的 runCommand 的等价物是什么？

Question

In MongoDB shell you can usedb.runCommand(...) . For example to show mongoDB users :

> db.runCommand({usersInfo:1})
....
list of users
....

This would be useful for User management commands

What is the equivalent in mongoose ?

Answer 1

I've found out here that we can use db.db.command :

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/test', {useNewUrlParser: true, useUnifiedTopology: true});

var db = mongoose.connection;

db.once('open', function callback () {
    db.db.command({usersInfo: 1}, function (err,result){
        console.log(result);
        mongoose.disconnect();
    });
});
