Python-Mail邮件发送

导入模块

import smtplib
from email import encoders
from email.header import Header
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.utils import parseaddr, formataddr
from email.mime.base import MIMEBase
from datetime import datetime

发送html格式的邮件

读取html文件内容发送邮件,转发和抄送没做函数参数,需要_format_addr函数进行美化成html格式的内容

def Sendmail(Smtp_server,Username,Password,addrlist,Title,Text):
    def _format_addr(s):
        name, addr = parseaddr(s)
        return formataddr ((Header(name, 'utf-8').encode (), addr))
    msg = MIMEText(Text, 'html', 'utf-8')

    msg['Subject'] = Header(Title, 'utf-8').encode() #邮件标题
    msg['From'] = _format_addr('cola <{}>'.format(Username)) # 发件人信息
    # msg['To'] = _format_addr ("liu <1431075018@qq.com>") #转发
    # msg['CC'] = _format_addr (
    #     "Hu Wei <zhang@qq.com>,liu <liu@qq.com>") #抄送
    server = smtplib.SMTP(Smtp_server)
    server.login(Username, Password)
    server.sendmail(Username, addrlist, msg.as_string ())
    server.quit()

if __name__ == "__main__":
    with open('test.html','r') as f:
        Text = f.read()
    Sendmail(
        Smtp_server = "smtp.exmail.qq.com",
        Username = "haoxincheng@qq.com",
        Password = "N24BfPgPk;kUHRVy",
        addrlist = [ "143107@qq.com","1850@163.com" ],
        Title = "MongoDB表日期检查是否是下一个交易日",
        Text = Text
    )

发送附件的邮件

在原有的发送html邮件基础上做的更改

def Sendmail(Smtp_server,Username,Password,addrlist,Title,Text):
    def _format_addr(s):
        name, addr = parseaddr(s)
        return formataddr ((Header(name, 'utf-8').encode (), addr))
    msg = MIMEMultipart() #构建一个方法,attach
    msg.attach(MIMEText(Title, 'html', 'utf-8'))

    msg['Subject'] = Header(Title, 'utf-8').encode() #邮件标题
    msg['From'] = _format_addr('cola <{}>'.format(Username)) # 发件人信息
    # msg['To'] = _format_addr ("liu <1431075018@qq.com>") #转发
    # msg['CC'] = _format_addr (
    #     "Hu Wei <zhang@qq.com>,liu <liu@qq.com>") #抄送

    with open('20210910.log', 'rb') as f:
        # 设置附件的MIME和文件名,这里是png类型,mime类型可以百度
        mime = MIMEBase('text', 'plain', filename='20210910.log')
        # 加上必要的头信息:
        mime.add_header('Content-Disposition', 'attachment', filename='20210910.log')
        mime.add_header('Content-ID', '<0>')
        mime.add_header('X-Attachment-Id', '0')
        # 把附件的内容读进来:
        mime.set_payload(f.read())
        # 用Base64编码:
        encoders.encode_base64(mime)
        # 添加到MIMEMultipart:
        msg.attach(mime)
        server = smtplib.SMTP(Smtp_server)
        server.login(Username, Password)
        server.sendmail(Username, to_addr, msg.as_string ())
        server.quit()
if __name__ == "__main__":
    with open('test.html','r') as f:
        Text = f.read()
    Sendmail(
        Smtp_server = "smtp.exmail.qq.com",
        Username = "haoxincheng@qq.com",
        Password = "N24BfPgPk。sdUHRVy",
        addrlist = [ "1431075018@qq.com","18501422535@163.com" ],
        Title = "邮件来了",
        Text = Text
    )
