MongoDB 查看所有用户账号信息

在 MongoDB 中创建了很多帐号，怎么查看所有帐号信息？

1. 查看全局所有账户

2. 查看当前库下的账户

查看全局所有账户 :

>  use admin
switched to db admin
> db.auth('admin','123456')
1
> db.system.users.find().pretty()
{
    "_id" : "admin.root",
    "user" : "root",
    "db" : "admin",
    "credentials" : {
        "SCRAM-SHA-1" : {
            "iterationCount" : 10000,
            "salt" : "******************==",
            "storedKey" : "*****************=",
            "serverKey" : "**************="
        }
    },
    "roles" : [
        {
            "role" : "read",
            "db" : "admin"
