Question

如果我在shell中运行：

mongo ds0219xx.mlab.com:219xx/dbname -u user -p pass

它可以工作并允许我连接到数据库并提取信息。但如果我在我的python应用程序（Flask）中并运行它：

import pymongo

client = pymongo.MongoClient("mongodb://user:pass@ds0219xx.mlab.com:219xx/dbname")

db = client["dbname"]

db.users.insert_one({
  "user1": "hello"
})

它给了我一个：

pymongo.errors.OperationFailure: Authentication failed.

我很确定它在进入insert_one（）调用之前就失败了，但我不完全确定。

谢谢！

编辑：根据要求，这是完整的回调：

Answer 1

我明白了。您可以从python文件中执行此操作，它将起作用：

connection = pymongo.MongoClient(ab123456.mlab.com, 123456)
db = connection[databasename]
db.authenticate(database_user, database_pass)

Answer 2

附加/?authSource=admin对我有所帮助。完整示例：

uri = 'mongodb://username:password@r1.example.net:27017/?authSource=admin'

client = MongoClient(uri)
db = client.test

result = db.users.find()

for document in result:
    print(document)

版本：pymongo 3.7.2

Answer 3

@Derek Schuster给出的答案是正确的。只是为了使其更清楚。

DB_NAME = database_name  
DB_HOST = dsxxxxxx.mlab.com
DB_PORT = 12345
DB_USER = user 
DB_PASS = pass

connection = MongoClient(DB_HOST, DB_PORT)
db = connection[DB_NAME]
db.authenticate(DB_USER, DB_PASS)

希望有帮助。：）

Answer 4

为mongo <4.0选择数据库后，您需要进行身份验证
