Pymongo Mongoclient 连接问题

Question

我已经从 MongoDB 的配置文件中启用了身份验证，并添加了一个具有 readWriteAnyDatabase 角色的用户。以下是查询：

db.createUser(
  {
    user: "username",
    pwd: "password",
    roles: [ { role: "readWriteAnyDatabase", db: "admin" } ]
  }
)

我正在尝试在本地系统上使用 pymongo 对 MongoDB 进行身份验证，但出现以下错误： 我正在使用以下配置：
pymongo==3.5.
python 3.6.8
Django==1.11.7
MongoDB 版本 v4.2.0

pymongo.errors.OperationFailure: command listIndexes requires authentication

下面是我的连接字符串：

  DB_NAME = 'somedb'    
  DATABASE_USERNAME = 'username'    
  DATABASE_PASSWORD = 'password'    
  DATABASE_HOST = '127.0.0.1'    
  DATABASE_PORT = '27017'    

  client = MongoClient('mongodb://{0}:{1}@{2}:{3}/?authSource=admin'.format(DATABASE_USERNAME, DATABASE_PASSWORD,
                                                                              DATABASE_HOST, DATABASE_PORT))
  DB = client.DB_NAME

或

  client = MongoClient('mongodb://username:password@127.0.0.1:27017/?authSource=admin')
  DB = client.DB_NAME

Answer 1

如果您希望您的用户拥有更广泛的权限，那么在运行 createUser 之后，您应该运行 updateUser。要授予对其他数据库的完全访问权限（我猜您正在尝试这样做），请在管理数据库中运行以下命令

use admin

db.updateUser(
   "username",
   { roles: [ { role: "root", db: "admin" } ] }
)

Answer 2

您已经在“admin”数据库上创建了用户，但在您的连接参数中，您正在连接到“somedb”。您必须切换到 admin db 并进行身份验证或在“somedb”中创建用户
