how can i validate username password for mongodb authentication through pymongo?
提问by Mrunmayee
I am refering to the http://api.mongodb.org/python/current/examples/authentication.htmlsite for authentication mechanism examples. I have created a User administrator and using its credentials I created a user for my 'reporting' database. Now i need to access the same through pymongo using the username and password. I tried the following commands in python shell. Is this the right way as my authentication is failing.
我指的是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“报告”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 访问它。我在 python shell 中尝试了以下命令。由于我的身份验证失败，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):

As an FYI, you can use the URI string format as well. The pseudocode looks like this:
仅供参考，您也可以使用 URI 字符串格式。伪代码如下所示：
pymongo.MongoClient('mongodb://user:password@server:port/')
pymongo.MongoClient('mongodb://user:password@server:port/')
Here's a simple connection code block with auth:
这是一个带有 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']
There are more options for the query string here: http://docs.mongodb.org/manual/reference/connection-string/
这里有更多的查询字符串选项：http: //docs.mongodb.org/manual/reference/connection-string/
Hope that helps = looks like you already have it though. Happy coding!!
希望有所帮助 = 看起来您已经拥有它了。快乐编码！！
