python3.7之12306搶票腳本實現
阿新 • • 發佈：2019-01-08
徹底 參考 info elf 軟件 類型 init 方式 驗證碼
悲催的12306，徹底淪為各路搶票軟件的服務提供方。元旦伊始，純粹12306官網及APP搶票，愈一周的時間，僅到手一張淩晨3:55回家的站票。為遠離腦殘，無奈選擇搶票軟件，預購年後返滬車票。BTW，研究一下搶票腳本的實現思路，參考：（https://juejin.im/post/5b116504f265da6e0636cbc2 - Python3.6實現12306火車票自動搶票）。
在原作者之上，對執行代碼做了以下處理：
- 刪除短信/郵件通知功能
- 刪除控制臺輸入功能
- 新增登陸cookie的刷新
- 新增多車次搶票
- 新增多座位類型搶票
註：使用 splinter.browser 在調用時，註意將 chrome驅動路徑（chromedriver.exe所在）配置在環境變量 - path 下。
代碼如下：
