我正在使用 djongo 和 django2 连接到 mlab mongodb 实例。 settings.py

    'default': {
        'ENGINE': 'djongo',
        'NAME': 'neon',
        'HOST': 'mongodb://username:password@ds249605.mlab.com:49605/mlab1',
    }
}

虽然我正在使用此设置，但 PyMongo 连接到本地 mongodb 实例。

主机在客户端这样

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'fitbitt',

        'CLIENT': {
        'host':'mongodb://your_username:your_password@ds363008.mlab.com:63008/fitbitt',
        'username':'your_username',
        'password':'your_password'
        }

    }
}
