公司的交易系統(tǒng)bs架構(gòu)，通過http方式訪問備份數(shù)據(jù)庫。開發(fā)公司不肯合作的態(tài)度，所以每一次必須人工的去登陸網(wǎng)站是手動(dòng)備份。 每天安排6次備份，這種對(duì)于一個(gè)程序開發(fā)者來講的話真是一種痛苦和侮辱。 今天空下來就用python開始編寫自動(dòng)備份方案： 1.http自動(dòng)登錄 2.wget斷點(diǎn)下載 3.7zip壓縮 4.網(wǎng)盤 everbox的同步到服務(wù)器 與http server的交互信息用wireshark抓包分析，還蠻靈光的 python代碼：
1 # -*- coding:utf-8 -*-
2 #auto backup system database
3 #自動(dòng)登錄，http下載，壓縮之后通過網(wǎng)盤同步到服務(wù)器
