在执行 eve 文档示例时，我得到了关于数据库的以下错误。有谁知道帮帮我。技术使用eve框架和mongodb。基本错误，所以任何人都可以解决它。

settings.py
MONGO_HOST = 'localhost'
MONGO_PORT = 5000
MONGO_USERNAME = 'user'
MONGO_PASSWORD = 'user'
MONGO_DBNAME = 'apitest'

DOMAIN = {'people': {}}

error

【解决方案1】：

首先验证 mongo 是否在您的机器上运行，请参阅 the Mongo documentation。在setting.py 中执行此操作后，将 mongo 信息更改为您的设置：

MONGO_HOST = 'localhost' # If your mongo server is locally running
MONGO_PORT = <port_to_your_mongo_server>
MONGO_USERNAME = ''
MONGO_PASSWORD = ''
MONGO_DBNAME = 'apitest'

遇到了同样的问题。

用户名和密码必须设置为空''

mongodb 默认情况下，没有身份验证。

因此，在 settings.py 中设置

MONGO_USERNAME = ''

MONGO_PASSWORD = ''
