python 发邮件

1、导入所需要的模块

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.header import Header

2、设置smtplib所需的参数

# 下面的发件人，收件人是用于邮件传输的。
smtpserver = 'exmail.qq.com'
username = 'XXX@daydaycook.com'
password = '***'
sender = 'XXX@daydaycook.com'
# receiver='[email protected]' 单个收件人
# 多个收件人
receiver = ['XXX@daydaycook.com', '***[email protected]']

3、构造邮件对象MIMEMultipart对象

subject = '中文标题'
subject = Header(subject, 'utf-8').encode()
# 下面的主题，发件人，收件人，日期是显示在邮件页面上的。
# MIMEMultipart主要有三种类型：mixed、alternative、related
msg = MIMEMultipart('mixed')
msg['Subject'] = subject
msg['From'] = 'XXX@daydaycook.com '
# msg['To'] = '[email protected]'
# 收件人为多个收件人,通过join将列表转换为以;为间隔的字符串
msg['To'] = ";".join(receiver)
# msg['Date']='2012-3-16'

4、构造文字内容

text = "嗨!\n你好吗?\nHere is the link you wanted:\nhttp://www.baidu.com"
text_plain = MIMEText(text, 'plain', 'utf-8')
msg.attach(text_plain)

5、构造图片附件

send_image_file = open(r'/Users/ddcuser/Downloads/true.jpeg', 'rb').read()
image = MIMEImage(send_image_file)
image.add_header('Content-ID', '')
image["Content-Disposition"] = 'attachment; filename="testimage.png"'
msg.attach(image)

6、构造html附件

# 发送正文中的图片:由于包含未被许可的信息，网易邮箱定义为垃圾邮件，报554 DT:SPM ：

html = """
  
    
    
    
Hi!
  
       How are you?
  
       Here is the link you wanted.
 
    
 
    
  
"""
text_html = MIMEText(html, 'html', 'utf-8')
text_html["Content-Disposition"] = 'attachment; filename="text_html.html"'
msg.attach(text_html)

7、构造压缩文件zip附件

sendfile = open(r'/Users/ddcuser/Downloads/20191211160425_sendCredit_result.zip', 'rb').read()
text_att = MIMEText(sendfile, 'base64', 'utf-8')
text_att["Content-Type"] = 'application/octet-stream'
# 附件可以重命名成aaa.zip
text_att.add_header('Content-Disposition', 'attachment', filename='aaa.zip')
msg.attach(text_att)

8、构造txt附件

sendfile = open(r'/Users/ddcuser/Downloads/20191211160425_sendCredit_result.txt', 'rb').read()
text_att = MIMEText(sendfile, 'base64', 'utf-8')
text_att["Content-Type"] = 'application/octet-stream'
# 附件可以重命名成aaa.txt
text_att.add_header('Content-Disposition', 'attachment', filename='aaa.txt')
msg.attach(text_att)

9、构造xls附件

sendfile = open(r'/Users/ddcuser/Downloads/20191211160425_sendCredit_result.xls', 'rb').read()
text_att = MIMEText(sendfile, 'base64', 'utf-8')
text_att["Content-Type"] = 'application/octet-stream'
# 附件可以重命名成aaa.xls
text_att.add_header('Content-Disposition', 'attachment', filename='aaa.xls')
msg.attach(text_att)

10、发送邮件

smtp = smtplib.SMTP()
# 发件人是腾讯企业邮箱，如果用其他邮箱需要修改参数
smtp.connect('smtp.exmail.qq.com')  
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
