如何通过pymongo验证mongodb身份验证的用户名密码？

Question

我参考http://api.mongodb.org/python/current/examples/authentication.html站点以获取身份验证机制示例。我创建了一个用户管理员，并使用其凭据为我的“报表”数据库创建了一个用户。现在我需要使用用户名和密码通过pymongo访问。我在python shell中尝试了以下命令。当我的身份验证失败时，这是正确的方法吗。

from pymongo import MongoClient

client = MongoClient('localhost')

client.reporting.authenticate('reportsUser', '123456', mechanism='MONGODB-CR')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/pymongo/database.py", line 746, in authenticate
    self.connection._cache_credentials(self.name, credentials)
  File "/usr/lib/python2.7/dist-packages/pymongo/mongo_client.py", line 441, in _cache_credentials
    auth.authenticate(credentials, sock_info, self.__simple_command)
  File "/usr/lib/python2.7/dist-packages/pymongo/auth.py", line 214, in authenticate
    auth_func(credentials[1:], sock_info, cmd_func)
  File "/usr/lib/python2.7/dist-packages/pymongo/auth.py", line 194, in _authenticate_mongo_cr
    cmd_func(sock_info, source, query)

    helpers._check_command_response(response, None, msg)

    raise OperationFailure(msg % errmsg, code)
pymongo.errors.OperationFailure: command SON([('authenticate', 1), ('user', u'reportsUser'), ('nonce', u'f8158a24f1c61650'), ('key', u'14cea216c54b93bae20acd2e076bb785')]) failed: auth failed

作为参考，您还可以使用URI字符串格式。伪代码如下所示：

pymongo.MongoClient（'mongodb://user:password@server:port/'）

下面是一个带有auth的简单连接代码块：

import pymongo
conn = pymongo.MongoClient('mongodb://root:pass@localhost:27017/')
db = conn['database']
coll = db['collection']

这里还有更多的查询字符串选项：http://docs.mongodb.org/manual/reference/connection-string/

希望能帮上忙。快乐编码！！
