通过Python自动压缩文件并发送邮件

前言：因为每次更新好日报程序都要把最新版本发给同事，所以萌生了做个程序自动合并文件——压缩文件——发送邮件——删除文件，其中压缩文件用了网上比较好用的轮子，删除文件夹和文件夹下的所有内容用了shutil.rmtree

import zipfile
import os
import shutil
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase #附件
from email.mime.text import MIMEText
from email import encoders #转码

def combine_file():
    '''首先判断是否有周末日报，如果有的话就删除；然后把日报和数据这两个文件夹复制到周末日报中'''
    if os.path.exists(r'C:\Users\Administrator\Desktop\报表\周末日报'):
        shutil.rmtree(r'C:\Users\Administrator\Desktop\报表\周末日报')
    os.mkdir(r'C:\Users\Administrator\Desktop\报表\周末日报')
    shutil.copytree(r'C:\Users\Administrator\Desktop\报表\日报',r'C:\Users\Administrator\Desktop\报表\周末日报\日报')
    shutil.copytree(r'C:\Users\Administrator\Desktop\报表\数据',r'C:\Users\Administrator\Desktop\报表\周末日报\数据')

def zipDir(dirpath, outFullName):
    '''
    压缩指定文件夹
    :param dirpath: 目标文件夹路径
    :param outFullName:  压缩文件保存路径+XXXX.zip
    :return: 无
    '''
    zip = zipfile.ZipFile(outFullName, 'w', zipfile.ZIP_DEFLATED)
    for path,dirnames,filenames in os.walk(dirpath):
        #取掉目标和路径，只对目标文件夹下边的文件及文件夹进行压缩
        fpath = path.replace(dirpath,'')
        for filename in filenames:
            zip.write(os.path.join(path, filename), os.path.join(fpath,filename))
    zip.close()

#邮件服务器基础设置
def server_pre(msg):
    server = smtplib.SMTP('mail.sh.ctc.com')
    server.starttls()
    fromAddr = '[email protected]'  # 发件人
    myPass = '******'  # 发件人密码
    server.login(fromAddr, myPass)
    server.send_message(msg)
    server.quit()

#发送邮件
def send_listing():
    global msg_list
    msg_list = MIMEMultipart()
    msg_list['From'] = '[email protected]'
    msg_list['To'] = '[email protected], [email protected]'
    msg_list['Subject'] = '周末日报'
    body = '周末日报'
    msg_list.attach(MIMEText(body))
    with open(r"C:\Users\Administrator\Desktop\报表\周末日报.zip",'rb') as f:
        #这里附件的MIME和文件名
        mime = MIMEBase('zip','zip',filename='周末日报.zip')
        #加上必要的头信息
        mime.add_header('Content-Disposition','attachment',filename=('gb2312', '', '周末日报.zip'))
        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)
        msg_list.attach(mime)
    server_pre(msg_list)
    print(">>>邮件发送成功！")

if __name__ =='__main__':
    combine_file()
    print('>>>合并报表成功！')
    dirpath = r'C:\Users\Administrator\Desktop\报表\周末日报'
    outFullName = r'C:\Users\Administrator\Desktop\报表\周末日报.zip'
    zipDir(dirpath, outFullName)
