发送简单邮件

　　使用第三方邮件服务商的SMTP服务发送邮件(本文中使用QQ邮箱的SMTP服务)

　　授权码获取：登录QQ邮箱->点击设置->点击账户->POP3/IMAP/SMTP.../CalDAV服务菜单下点击生成授权码，将生成的授权码作为密码

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr

send_mail = 'xxxxxxx@qq.com'  #发件人邮箱账号
send_pwd = 'xxxxxxx'    #发件人邮箱密码 授权码
receiv_mail = 'xxxxxxx@qq.com'  #收件人邮箱账号

msg = MIMEText('这是一封测试邮件','plain','utf-8')  #邮件正文
msg['From'] = formataddr(['Fromxxx',send_mail]) #发件人昵称，邮箱账号
msg['To'] = formataddr(['to',receiv_mail])    #收件人昵称，邮箱账号
msg['Subject'] = '测试邮件'         #邮件主题
server = smtplib.SMTP_SSL('smtp.qq.com',465)  #发件人邮箱中的SMTP服务器，端口号为465
server.login(send_mail,send_pwd)   #发件邮箱账号、密码
server.sendmail(send_mail,[receiv_mail,],msg.as_string())  #发送邮件
server.quit()  #关闭连接

发送HTML格式的邮件

import smtplib
from email.mime.text import MIMEText
from email.header import Header

send_mail = 'xxxxx@qq.com'
send_pwd = 'xxxxx'
receiv_mail = 'xxxxx@qq.com'

mail_msg ='''
<p>这是一封测试邮件</p>
<p><a href="">点我激活</a></p>
'''

msg = MIMEText(mail_msg,'html','utf-8')
msg['From'] = Header('测试邮件','utf-8')
msg['To'] = Header('测试','utf-8')
subject = '发送HTML格式的邮件'
msg['Subject'] = Header(subject,'utf-8')

server = smtplib.SMTP_SSL('smtp.qq.com',465)
server.login(send_mail,send_pwd)
server.sendmail(send_mail,[receiv_mail,],msg.as_string())
server.quit()

发送带附件的邮件

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

send_mail = 'xxxxx@qq.com'
send_pwd = 'xxxxx'
receive_mail = 'xxxxx.com'

msg = MIMEMultipart()
msg['From'] = Header('测试邮件','utf-8')
msg['To'] = Header('测试','utf-8')
subject = '邮件'
msg['Subject'] = Header(subject,'utf-8')
msg.attach(MIMEText('这是一封测试附件的邮件','plain','utf-8'))  #邮件正文

att1 = MIMEText(open('text.txt','rb').read(),'base64','utf-8')  #附件1
att1['Content-Type'] = 'application/octet-stream'
att1['Content-Disposition'] = 'attachment;filename="text.txt"'
msg.attach(att1)

server = smtplib.SMTP_SSL('smtp.qq.com',465)
server.login(send_mail,send_pwd)
server.sendmail(send_mail,[receive_mail,],msg.as_string())
server.quit()

在HTML中添加图片

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

send_mail = 'xxxxx@qq.com'
send_pwd = 'xxxxx'
receiv_mail = 'xxxxx@qq.com'

msg = MIMEMultipart('related')
msg['From'] = Header('测试邮件','utf-8')
msg['To'] = Header('测试','utf-8')
subject = '发送HTML格式的邮件'
msg['Subject'] = Header(subject,'utf-8')

msgAlternative = MIMEMultipart('alternative')
msg.attach(msgAlternative)


mail_msg ='''
<p>这是一封添加图片的测试邮件</p>
<p>图片演示：</p>
<p><img src='cid:image1'></p>
'''

msgAlternative.attach(MIMEText(mail_msg,'html','utf-8'))

pic = open('123.png','rb')
msgImage = MIMEImage(pic.read())
pic.close()

msgImage.add_header('Content-ID','<image1>')
msg.attach(msgImage)

server = smtplib.SMTP_SSL('smtp.qq.com',465)
server.login(send_mail,send_pwd)
server.sendmail(send_mail,[receiv_mail,],msg.as_string())
server.quit()
