Question

我已经安装了mongodb并启用了auth。和它的工作发现。我可以使用robomongo应用程序从远程笔记本连接它：

Host: SERVER_IP
PORT: 27017
DATEBASE: prod-db
USERNAME: user_name
PASS: user_password
Auth Mechanism: MONGODB-CR

我们可以使用以下方式从本地服务器shell连接：

$ mongo prod-db -u user_name -p user_password

一切正常，但是当我们尝试使用pymongo api时。身份验证失败。下面是python代码：

from pymongo import MongoClient

client = MongoClient()
client.prod_db.authenticate('user_name', 'user_password', mechanism='MONGODB-CR')
db = client.prod_db
result = db.users.find()

for document in result:
    print(document)

使用的工具：

python 2.7
pymongo versiob 3.3.1
MongoDB shell version: 2.6.10
$ mongod --version
db version v2.6.10
2016-10-31T16:34:59.868+0000 git version: nogitversion
2016-10-31T16:34:59.868+0000 OpenSSL version: OpenSSL 1.0.2g  1 Mar 2016

错误追踪：

    raise OperationFailure(msg % errmsg, code, response)

解决方案： 问题是数据库名称，以下代码工作正常：

from pymongo import MongoClient

client = MongoClient('mongodb://user_name:user_password@localhost:27017/prod-db')
db = client['prod-db']

result = db.users.find()
for document in result:
    print document

请尝试这样的事情：

Answer 2

如果您尝试了上述答案，但仍然出现错误：

pymongo.errors.OperationFailure: Authentication failed.

您很有可能需要在您的uri末尾添加?authSource=admin。

这是我在MongoDB服务器版本4.2.6和MongoDB Shell版本v3.6.9中使用的有效解决方案。

from pymongo import MongoClient

# Replace these with your server details
MONGO_HOST = "XX.XXX.XXX.XXX" 
MONGO_PORT = "27017"
MONGO_DB = "database"
MONGO_USER = "admin"
MONGO_PASS = "pass"

uri = "mongodb://{}:{}@{}:{}/{}?authSource=admin".format(MONGO_USER, MONGO_PASS, MONGO_HOST, MONGO_PORT, MONGO_DB)
client = MongoClient(uri)

类似的命令行修复程序正在添加--authenticationDatabase admin

Answer 3

这对我有用....

import pymongo

client = pymongo.MongoClient("mongodb://username:12%40password@ip:27017/sample_db",authSource="admin") 
db = client['sample_db']

请记住，如果密码中包含特殊字符（例如＃，@），则需要对密码进行编码（请参见％40）。如果不执行authSource =“ admin”，将收到身份验证错误。 username-您的mongodb用户名，ip-ip地址，因为它假定数据库托管在远程服务器上。 sample_db是您要访问的数据库。

Answer 4

对于pymongo，

尝试以下MongoDB 4：

添加authSource：这是具有用户凭据集合的数据库的名称。

例如：

client = MongoClient(host=<<hostname>>,
                     port=<<port>>, 
                     username=<<user_name>>, 
                     password=<<password>>,
                    authSource="admin")
db_obj = client[db_name]

pymongo auth在python脚本中失败
