Python3实现带附件的定时发送邮件功能

本文实例为大家分享了Python3定时发送邮件功能的具体代码，供大家参考，具体内容如下

1、 导入模块

import os
import datetime #定时发送，以及日期
import shutil #文件操作
import smtplib #邮件模块
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
import time
import xlwt #excel写入

2、写入EXCEL

def eWrite(fLocate,file_sheet,file_subject,style0):
 try:
  if os.path.exists(fLocate):
   os.remove(fLocate) # 如果文件存在，则删除
  f = xlwt.Workbook(encoding='utf-8') #打开excel文件
  fs = f.add_sheet(file_sheet) #sheet名
  subject = list(file_subject) #列表化
  for i in range(len(subject)): #找到日期列
   if '日期' in subject[i]:
    col_num=i
  for i in range(len(subject)): #sheet标题
   fs.write(0, i, subject[i])

  for i in range(10): #单元格宽度为
   fs.col(i).width=3333

  print("WRITE FINISHED")
  f.save(fLocate)
 except :
  print ("WRITE FAILED")

3、发送邮件

def eSend(sender,receiver,username,password,smtpserver,subject,e_content,file_path,file_name):
 try:
#邮件头
  message = MIMEMultipart()
  message['From'] = sender#发送
  message['To'] = ",".join(receiver)#收件
  message['Subject'] = Header(subject, 'utf-8')
  message.attach(MIMEText(e_content, 'plain', 'utf-8'))# 邮件正文

# 构造附件
  att1 = MIMEText(open(file_path+file_name,'rb').read(), 'base64', 'utf-8')
  att1["Content-Type"] = 'application/octet-stream'
  att1["Content-Disposition"] = "attachment;filename="+file_name
  message.attach(att1)

#执行
  smtp = smtplib.SMTP()
  smtp.connect(smtpserver) #连接服务器
  smtp.login(username, password) #登录
  smtp.sendmail(sender, receiver, message.as_string()) #发送
  smtp.quit()
  print("SEND")
 except:
  print("SEND FAILED")

4、配置与执行

while True:
#配置
 #__time_____
 ehour=11#定时小时
 emin=49#定时分钟
 esec=50#定时秒
 current_time = time.localtime(time.time())  #当前时间date
 cur_time = time.strftime('%H%M', time.localtime(time.time()))    #当前时间str
 #__mysql_____

 #__email_____
 sender = '' # 发件人邮箱
 receiver = ['[e-mail]'] # 收件人邮箱，可以多个（列表形式）群发
 username = '' # 发件人姓名
 password = '' # smtp密码，qq是给你分配一串，163是自己设置
 smtpserver = '' # 邮箱服务器

 subject = "Hey,here's something interesting"  #邮件标题
 e_content = '{0:^27}\n{1:^27}\n{2:^25}\n{3:^25}'.format('i','/ \\','(-----)','(--------)') #邮件正文
 #__file_____
 file_path = "D:/" #文件位置
 file_name="shit.xls" #文件名
 fLocate = file_path + file_name  #文件路径
 file_subject='I', 'MISS', 'U' #sheet标题
 file_sheet='ok' #sheet名
 style0=xlwt.XFStyle()
 style0.num_format_str='YYYY-MM-DD'
#操作
 if ((current_time.tm_hour == ehour) and (current_time.tm_min == emin) and (current_time.tm_sec == esec)):
  print ("START")
  eWrite(fLocate, file_sheet, file_subject,style0)
  eSend(sender, receiver, username, password, smtpserver, subject, e_content, file_path,file_name)
  print(cur_time)
 time.sleep(1)
