前言

之前有一次忘記了好友的生日，一直覺得過意不去。之前把親友的生日都直接寫在備忘錄里面，一個個的設置在手機的日期提醒里面有些麻煩，于是寫一個程序來提醒我，提醒方式是發郵件。

步驟

思考了一下，有幾個難點：

統一備忘錄格式
我的生日備忘錄里面，記錄有親友的農歷生日和公歷生日，農歷和公歷要相互轉換。
發郵件
要找個服務器定時執行python腳本。

一個一個的來解決。

統一備忘錄格式

把備忘錄文本復制到一個csv文件，birthday.csv

birthday.csv

張三,公歷,4.15
李四,農歷,3.23
王五,農歷,3.10
趙六,農歷,3.10

農歷和公歷轉換

沒有找到python好用的庫，找到一段程序，親測有效。

發郵件

發郵件分兩步，一是填寫郵件標題和內容等信息，二是通過smtp協議發送郵件，這兩個都有現成的python庫
qq.py

# -*- coding: utf-8 -*-

import smtplib
from email.mime.text import MIMEText


def sendMail(title: str, msg: str):
    # 設置服務器所需信息
    # qq郵箱服務器地址

    # 授權碼
    mail_pass = 'xxxxxxxxxxxxx'
    # 發送方郵箱地址
    sender = 'xxxxxxxxxxx@qq.com'
    # 接收方郵件地址
    receivers = ['xxxxxxxxxxx@qq.com']

    # 設置email信息
    # 郵件內容設置
    message = MIMEText(msg,'plain','utf-8')
    # 郵件主題
    message['Subject'] = title
    # 發送方信息
    message['From'] = sender
    # 接受方信息
    message['To'] = receivers[0]

    # 登錄并發送郵件
    try:
        smtpObj = smtplib.SMTP()
        # 連接到服務器
        smtpObj.connect(mail_host, 25)
        # 登錄到服務器
        smtpObj.login(mail_user, mail_pass)
        # 發送
        smtpObj.sendmail(
            sender, receivers, message.as_string())
        # 退出
        smtpObj.quit()
        print('郵件發送成功')
