email自動寄發
1. 程式開發 (名稱:mail_ReadF.py)
1.1 功能說明
本程式執行後，自動寄出email，寄出的內容可依照讀取的參數檔內容而決定，參數檔可依需要，事先設定好，當程式執行後即自動帶出，參數檔可任意設定，故可靈活彈性運用，寄出各種email的內容，
參數檔設定的項目共5項，即以0 1 2 3 4 代表5種不同的要項，
如下說明
0, Subject (信主旨) 主旨後面，追加記入程式執行的日時分
1, to_address (收信者) 可填入多個 id ,若無 以from_address表示
2, attachments (附件檔) 可傳送多個附件檔
3, from_address (寄信者) 若無填入 [email protected]
4, contents (信內文) 可用多行陳述信件內容
1.2 開發工具 : Python 3.8.3 [MSC v.1916 64 bit (AMD64)]。
編輯工具 Spyder 4.1.4
1.3 使用模組Module/套件 : import os , smtplib SMTP郵件傳輸協定 SMTP伺服器 smtp=smtplib.SMTP_SSL('192.168.XX.XX', 465) #SSL
其他SMTP服務:
Gmail smtp.gmail.com 64.233.189.109
Yahoo smtp.mail.yahoo.com 106.10.248.80
Hotmail smtp.live.com hkg-efz.ms-acdc.office.com 52.98.40.66 Outlook smtp-mail.outlook.com
hkg-efz.ms-acdc.office.com [40.100.54.210]
非SMTP: 直接於OUTLOOK 開啟中自動寄信
2. 實際運用：
2,1 參數檔實際說明
0,[Warning] DB export job was unsuccessful, to refer the lastest log file
1, [email protected], [email protected]
2, Dump_20230813.txt
4, 課長 好
4,
4, 標題所示 export job 執行無成功，最新log file 參考如下:
4,
4, \\D$\Datapum\xxx\Export\Dump
4, 以上通知
2.2 執行後寄出內容
件名: [Warning] DB export job was unsuccessful, to refer the lastest log file-- sent 2023/08/13 14:49
寄件者: [email protected]
寄給 [email protected], [email protected]
附件檔: Dump_20230813.txt
信件本文:
課長 好
標題所示 export job 執行無成功，最新log file 參考如下:
以上通知
2.3 自動執行Bat檔，本程式檔，參數檔，需存置於同一資料夾內
3. 擴充運用：
3.1 各部門各業務的定期報表，日報月報等，可利用本程式，設定自動排程，可以自動寄出給各擔當，於非上班時間仍可自動寄信，節省人力工時，減少耽誤延遲等現象發生
3.2 可搭配各項業務自動排程，對每日或定期執行的程式，一旦執行失敗時，可及時寄出警告信，擔當可及時對應，避免事件擴大發生。
例如DB backup失敗，
電話通話時間異常，
機器關機/重新開啟現象發生
…
3.3 定期eMail 寄出記錄檔，可供確認保存，當做稽查時，備查之憑證記錄，減少人員手工紀錄工時
