公司的交易系统bs架构，通过http方式访问备份数据库。开发公司不肯合作的态度，所以每一次必须人工的去登陆网站是手动备份。 每天安排6次备份，这种对于一个程序开发者来讲的话真是一种痛苦和侮辱。 今天空下来就用python开始编写自动备份方案： 1.http自动登录 2.wget断点下载 3.7zip压缩 4.网盘 everbox的同步到服务器 与http server的交互信息用wireshark抓包分析，还蛮灵光的 python代码：
1 # -*- coding:utf-8 -*-
2 #auto backup system database
3 #自动登录，http下载，压缩之后通过网盘同步到服务器
