python - 无法对 PyMongo 数据库进行身份验证

Question

这是我用来尝试验证的代码:

# MongoDB connection
connection = Connection(f.config['MONGODB_HOST'], f.config['MONGODB_PORT'])
db = connection['MONGODB_DB']

# Try authenticating. This will only work in production. In development,
# MONGODB_USER and MONGODB_PASSWORD will raise KeyErrors.
try:
    db.authenticate(f.config['MONGODB_USER'], f.config['MONGODB_PASSWORD'])
except KeyError:
    f.logger.debug('KeyError: Not authenticating.')

# Temporary. This is just for testing purposes.
users = db.users 
user = users.find_one({'username': 'BrewerOnRails'})

我的配置是从一个名为 ProductionConfig 的对象加载的:

class Config(object):
    '''Default configuration object.'''
    DEBUG = False
    TESTING = False
    PORT = int(os.environ.get('PORT', 5000))

class ProductionConfig(Config):
    '''Configuration object specific to production environments.'''
    REDIS_URL = os.environ.get('REDISTOGO_URL')
    if REDIS_URL:
        url = urlparse.urlparse(REDIS_URL)
        REDIS_HOST = url.hostname
        REDIS_PORT = url.port
        REDIS_PASSWORD = url.password

    MONGOLAB_URI = os.environ.get('MONGOLAB_URI')
    if MONGOLAB_URI:
        url = urlparse.urlparse(MONGOLAB_URI)
        MONGODB_USER = url.username
        MONGODB_PASSWORD = url.password
        MONGODB_HOST = url.hostname
        MONGODB_PORT = url.port
        MONGODB_DB = url.path[1:]

这是我不断收到的错误:

pymongo.errors.OperationFailure: database error: unauthorized db:MONGODB_DB lock type:-1 client:10.117.107.165

PyMongo 的 _unpack_response 引发了 OperationFailure 异常helpers.py 文件中的函数，特别是第 103 和 104 行。

这在我看来是错误的:

db = connection['MONGODB_DB']

也许你想要

db = connection[config['MONGODB_DB']]
