python自动下载邮件_python实现邮件自动化

1、自动接收邮件并且下载附件，使用pop3协议。

# 接收邮件并下载邮件附件

import poplib

import email

import datetime

import time

from email.parser import Parser

from email.header import decode_header

import traceback

import telnetlib

import sys

# from email.utils import parseaddr

class c_step4_get_email:

# 字符编码转换

@staticmethod

def decode_str(str_in):

value, charset = decode_header(str_in)[0]

if charset:

value = value.decode(charset)

return value

# 解析邮件,获取附件

@staticmethod

def get_att(msg_in, str_day_in):

# import email

attachment_files = []

for part in msg_in.walk():

# 获取附件名称类型

file_name = part.get_filename()

# contType = part.get_content_type()

if file_name:

h = email.header.Header(file_name)

# 对附件名称进行解码

dh = email.header.decode_header(h)

filename = dh[0][0]

if dh[0][1]:

# 将附件名称可读化

filename = c_step4_get_email.decode_str(str(filename, dh[0][1]))

print(filename)

# filename = filename.encode("utf-8")

# 下载附件

data = part.get_payload(decode=True)

# 在指定目录下创建文件，注意二进制文件需要用wb模式打开

att_file = open(r'C:\Users\Administrator\Desktop\test' + '\\' + filename, 'wb')

attachment_files.append(filename)

att_file.write(data) # 保存附件

att_file.close()

return attachment_files

@staticmethod

def run_ing():

# 输入邮件地址, 口令和POP3服务器地址:

email_user = 'zgcindex_zh@163.com'

# 此处密码是授权码,用于登录第三方邮件客户端

password = input('请输入您的密码：') #

pop3_server = 'pop.163.com'

# 日期赋值

day = datetime.date.today() - datetime.timedelta(days=1)#周一days=3

str_day = str(day).replace('-', '')

print(str_day)

# 连接到POP3服务器,有些邮箱服务器需要ssl加密，可以使用poplib.POP3_SSL

try:

telnetlib.Telnet('pop.163.com', 995)

server = poplib.POP3_SSL(pop3_server, 995, timeout=10)

except:

time.sleep(5)

server = poplib.POP3(pop3_server, 110, timeout=10)

# server = poplib.POP3(pop3_server, 110, timeout=120)

# 可以打开或关闭调试信息

# server.set_debuglevel(1)

# 打印POP3服务器的欢迎文字:

print(server.getwelcome().decode('gb18030'))#utf-8

# 身份认证:

server.user(email_user)

server.pass_(password)

# 返回邮件数量和占用空间:

print('Messages:%s. Size:%s' % server.stat())

# list()返回所有邮件的编号:

resp, mails, octets = server.list()

# 可以查看返回的列表类似[b'1 82923', b'2 2184', ...]

print(mails)

index = len(mails)

# 倒序遍历邮件

# for i in range(index, 0, -1):

# 顺序遍历邮件

for i in range(index, index - 100, -1): # 1988, 1989 0,index+1,-1 index，index+1

resp, lines, octets = server.retr(i)

# lines存储了邮件的原始文本的每一行,

# 邮件的原始文本:

msg_content = b'\r\n'.join(lines).decode('gb18030')#('utf-8')

# 解析邮件:

msg = Parser().parsestr(msg_content)

# 获取邮件时间,格式化收件时间

date1 = time.strptime(msg.get("Date")[0:24], '%a,%d%b %Y %H:%M:%S')

# 邮件时间格式转换

date2 = time.strftime("%Y%m%d", date1)

if date2 < str_day:

# 倒叙用break

break

# 顺叙用continue

# continue

else:

# 获取附件

c_step4_get_email.get_att(msg, str_day)

# print_info(msg)

server.quit()

if __name__ == '__main__':

# @version : 3.4

# @Author : robot_lei

# @Software: PyCharm Community Edition

# log_path = 'C:\\fakepath\\log.log'

# logging.basicConfig(filename=log_path)

origin = sys.stdout

f = open(r'C:\Users\Administrator\Desktop\receive\123.txt', 'w')

sys.stdout = f

try:

c_step4_get_email.run_ing()

except Exception as e:

s = traceback.format_exc()

print(e)

tra = traceback.print_exc()

sys.stdout = origin

f.close()

2、自动按邮箱地址列批量发送excel文件，使用SMTP协议。

#按邮箱对应回复反馈邮件

from email.mime.text import MIMEText

import smtplib

from email.header import Header

from email.utils import parseaddr,formataddr#设置编码格式

from email.mime.base import MIMEBase

from email.mime.multipart import MIMEMultipart

from email import encoders

import openpyxl

import pandas as pd

import time

time.strftime("%Y/%m/%d", time.localtime())

data_path = r"C:\Users\Administrator\Desktop\0807zongbiao.xlsx"

data = pd.read_excel(data_path)

reply_root_path = r"C:\Users\Administrator\Desktop\ttt"

# for email_id,value in data.groupby("发件人邮箱"):

# current_time = time.strftime("%Y%m%d", time.localtime())

# reply_path = reply_root_path + "\回复附件#" + current_time+ "#" + email_id + '.xlsx'

# value.reset_index(drop=True).to_excel(reply_path)

#打开excel文件,读取邮箱地址和审核意见列

# wb=openpyxl.load_workbook(r'C:\Users\Administrator\Desktop\0801zongbiao.xlsx')

# sheet=wb.get_active_sheet()

# to_addrs=list(sheet.columns)[9]

# body=list(sheet.columns)[9]

#for item in list(sheet.columns)[10]:

#print(item.value)

#将用户名编码设置成UTF-8

def _format_addr(s):

name,addr=parseaddr(s)

return formataddr((Header(name, 'utf-8').encode(),addr))

#定义email的地址，口令和SMTP服务器地址

from_addr='zgcindex_zh@163.com'

password=input('请输入发送邮箱的密码：')#

smtp_server='smtp.163.com'

# to_addr='sx_wy123@163.com'

#定义邮件本身内容

# msg=MIMEMultipart()

# msg['From']=_format_addr('发送者的ReedSun'%from_addr)

# msg['To']=_format_addr('接收者的ReedSun'%to_addr)

# msg['Subject']=Header('回复','utf-8').encode()

#定义邮件正文

# msg.attach(MIMEText('使用python发来的邮件3','plain','utf-8'))

#加附件

for email_id,value in data.groupby("发件人邮箱"):

current_time = time.strftime("%Y%m%d", time.localtime())

reply_path = reply_root_path + "\回复附件#" + current_time+ "#" + email_id + '.xlsx'#文件名

value.reset_index(drop=True).to_excel(reply_path)

to_addr=email_id

msg=MIMEMultipart()

msg['From']=_format_addr('发送者的ReedSun'%from_addr)

msg['To']=_format_addr('接收者的ReedSun'%to_addr)

msg['Subject']=Header('总后审核意见','utf-8').encode()

msg.attach(MIMEText('总后新品申请审核意见，详情请见附件！注：有多封申请邮件的公司，不再分别回复，统一一并回复到附件中！请大家一定按要求格式申请，否则可能会无法正常申请上架，谢谢配合~','plain','utf-8'))

with open(reply_path,'rb') as f:

# 设置附件的MIME和文件名，这里是jpg类型,可以换png或其他类型:

mime=MIMEBase("\回复附件#" + current_time+ "#" + email_id, 'xlsx', filename="\回复附件#" + current_time+ "#" + email_id + '.xlsx')

mime.add_header('Content-Disposition','attchment',filename=reply_path)

mime.add_header('Content-ID','<0>')

mime.add_header('X-Attachment-ID','0')

mime.set_payload(f.read())

encoders.encode_base64(mime)

msg.attach(mime)

#定义发送文件

server=smtplib.SMTP_SSL(smtp_server,465)

server.set_debuglevel(1)

server.login(from_addr,password)

server.sendmail(from_addr,to_addr,msg.as_string())

server.quit()

这次弄完之后发现python做一些重复事情自动化的事情真的是很有用呢~

找工作中，希望工作快砸来吧。
