l0n0lhttputils 1.2.0

平时常用的http server|mysql|配置文件

简单服务器开发框架

1.使用文档

安装

pip install l0n0lhttputils

使用方法，以微信登录验证为例

# 配置文件 config.yaml
mysql_host: localhost
mysql_port: 13306
mysql_user: root
mysql_password: '123'
mysql_db: 'test'

token_expire_time: 120

listen_host: localhost
listen_port: 12345

appid: 111
secret_key: xxxxxxxx
