使用PyMongo列出某些数据库的用户 [英] Listing users for certain DB with PyMongo

问题描述

我正在尝试为某个数据库获取用户.

I'm trying to fetch users for a certain database.

我能够找到列出数据库或创建用户的功能，但没有找到列出用户的功能，我考虑过调用任意命令(例如show users)，但是我找到了实现它的任何方法.

I was able to find function to list the databases or create users but none for listing the users, I thought about invoking an arbitrary command such as show users but I could find any way to do it.

#/usr/bin/python

from pymongo import MongoClient

client = MongoClient("localhost",27017)
db = client.this_mongo

试错

我可以看到数据库名称并打印它们，但没有其他内容:

Trial and error

I can see the DB names and print them but nothing further:

db_names = client.database_names()

#users = db.command("show users")
for document in db_names:
    print(document)
#cursor = db.add_user('TestUser','Test123',roles={'role':'read'})

如果只有一个可以获取用户光标的函数，以便我可以对其进行迭代，那么它会很棒.

If there was only a function that could fetch the users cursor so I can iterate over it it would be great.

#/usr/bin/python

from pymongo import MongoClient

client = MongoClient("localhost",27017)
db = client.this_mongo

# This is the line I added with the help of @salmanwahed
listing = db.command('usersInfo')

for document in listing['users']:
    print document['user'] +" "+ document['roles'][0]['role']

谢谢大家，特别感谢@salmanwahed！

Thank you all and @salmanwahed specifically!

推荐答案

您可以执行 usersInfo 命令来获取用户数据.喜欢:

You can execute the usersInfo command to fetch the users data. Like:

db.command('usersInfo')

它将返回如下结果:(我已经创建了testingdb用于测试)

It will return you a result like this: (I had created the testingdb for testing)

{u'ok': 1.0,
 u'users': [{u'_id': u'testingdb.TestUser',
   u'db': u'testingdb',
   u'roles': [{u'db': u'testingdb', u'role': u'read'}],
   u'user': u'TestUser'}]}
