python - 邮件发送

因为公网ip是动态的，想做一个在ip发生改变后邮件提醒

1. 首先需要开启smtp服务

开启后复制授权密码

2. 邮件发送

import smtplib
from email.mime.text import MIMEText

From = '[email protected]' # 发件人邮箱
To = From
pwd = 'ZZZZZZZZZZZZZZZZ' # 授权码

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com',25)
print(smtp.login(From, pwd))

mail = MIMEText('''内容''') # 内容
mail['Subjcet'] = '主题' # 主题
mail['From'] = 'AI' # 发件人(说明作用）
mail['To'] = 'Master' # 接收者(说明作用)

smtp.sendmail(From, To, mail.as_string())
print('send email success')

smtp.quit()

3. 检查ip后定时发送

import smtplib
import requests
import random
import datetime
from email.mime.text import MIMEText
from time import sleep

From = '[email protected]' # 发件人邮箱
To = From
pwd = 'ZZZZZZZZZZZZZZZZ' # 授权码

ip = ''
urls = ['https://checkip.amazonaws.com/', 'http://ip.42.pl/raw']

while True:
    sleep(10)
    res = requests.get(random.choice(urls))
    if ip == res.text.strip():
        print(f'now ip: {ip} ', end='')
        print(f"now time: {datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')}")
        continue
    ip = res.text.strip()

    smtp = smtplib.SMTP()
    smtp.connect('smtp.163.com',25)
    print(smtp.login(From, pwd))

    mail = MIMEText(f'new ip: {ip}') # 内容
    mail['Subjcet'] = 'AI' # 主题
    mail['From'] = 'AI' # 发件人(说明作用）
    mail['To'] = 'Master' # 接收者(说明作用)

    smtp.sendmail(From, To, mail.as_string())
    print('send email success.')
    print(f'new ip: {ip} ', end='')
    print(f"now time: {datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')}")
    smtp.quit()
