MongoLab / PyMongo接続エラー

シェルで実行する場合：

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

それは機能し、データベースに接続して情報を取得することができます。しかし、私がpythonアプリケーション（Flask）内にいて、これを実行する場合：

import pymongo

client = pymongo.MongoClient("mongodb://user:[email protected]:219xx/dbname")

db = client["dbname"]

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

それは私に：

pymongo.errors.OperationFailure: Authentication failed.

Insert_one（）呼び出しに到達する前に失敗していることはかなり確信していますが、完全にはわかりません。

ありがとう！

私はそれを考え出した。 pythonファイルからこれを行うことができ、それは機能します：

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

追加/?authSource=admin 助けて頂きました。完全な例：

uri = 'mongodb://username:[email protected]:27017/?authSource=admin'

client = MongoClient(uri)
db = client.test

result = db.users.find()

for document in result:
    print(document)

バージョン：pymongo 3.7.2

Mongo <4.0のデータベースを選択した後、認証する必要があります

@DerekSchusterの答えは正しかった。より明確にするためだけに。

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)

それが役に立てば幸い。 :)
