pymongo auth在python脚本中失败了

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连接服务器shell:

$ 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

错误跟踪:

    raise OperationFailure(msg % errmsg, code, response)

解决方案: 问题在于数据库名称,以下代码正常工作:

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

Answer 1

请尝试这样的事情:

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

Answer 2

如果您已经尝试了上述答案，但仍然出现错误：

pymongo.errors.OperationFailure: Authentication failed.

您很有可能需要添加?authSource=admin到 uri 的末尾。

这是我与 MongoDB 服务器版本 4.2.6 和 MongoDB shell 版本 v3.6.9 一起使用的工作解决方案。

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)

命令行的类似修复正在添加 --authenticationDatabase admin

Answer 3

对于皮蒙戈，

试试下面的MongoDB 4：

添加authSource：这是包含用户凭据集合的数据库的名称。

前任：

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

编辑 1：我也在 Mongo 3.x 版本上尝试过这个。也为此工作。
