1 发送文本信息

'''加密发送文本邮件'''
def sendEmail(from_addr,password,to_addr,smtp_server):
 try:
  msg = MIMEText('你好,来自信息化工程所的问候...', 'plain', 'utf-8') # 文本邮件
  # msg = MIMEText('<html><body><h2>你好</h2>' + '<p>send by <a href="http://www.python.org" rel="external nofollow" rel="external nofollow" >信息化工程所
    </a>...</p>' +'</body></html>', 'html', 'utf-8') # 网页文件
  msg['From'] = _format_addr('信息化工程所 <%s>' % from_addr)
  msg['To'] = _format_addr('收件人 <%s>' % to_addr)
  msg['Subject'] = Header('邮件的主题：问候', 'utf-8').encode()
  server = smtplib.SMTP(smtp_server, 25)
  server.starttls() # 调用starttls()方法，就创建了安全连接
  # server.set_debuglevel(1) # 记录详细信息
  server.login(from_addr, password) # 登录邮箱服务器
  server.sendmail(from_addr, [to_addr], msg.as_string()) # 发送信息
  server.quit()
  print("加密后邮件发送成功！")
 except Exception as e:
  print("发送失败：" + e)

2 发送带图片附件的邮件

'''发送带图片附件的邮件'''
def sendFileEmail(from_addr,password,to_addr,smtp_server):
 try:
  msg = MIMEMultipart()
  msg['From'] = _format_addr('信息化工程所 <%s>' % from_addr)
  msg['To'] = _format_addr('收件人 <%s>' % to_addr)
  msg['Subject'] = Header('邮件的主题：问候', 'utf-8').encode()
  # 邮件正文是MIMEText:
  msg.attach(MIMEText('send with file...', 'plain', 'utf-8'))
  # msg.attach(MIMEText('<html><body><h2>你好</h2>' + '<p>send by <img src=cid:0"></p>' +'</body></html>', 'html', 'utf-8')) # 网页文件

  # 添加附件就是加上一个MIMEBase，从本地读取一个图片:
  with open(r'./file/图片.png', 'rb') as f:
   mime = MIMEBase('image', 'png', filename='图片.png') # 设置附件的MIME和文件名，这里是png类型:
   mime.add_header('Content-Disposition', 'attachment',filename=('gbk', '', '图片.png')) # 加上必要的头信息,解决中文附件名乱码
   mime.add_header('Content-ID', '<0>')
   mime.add_header('X-Attachment-Id', '0')
   mime.set_payload(f.read()) # 把附件的内容读进来:
   encoders.encode_base64(mime) # 用Base64编码:
   msg.attach(mime) # 添加到MIMEMultipart:
  server = smtplib.SMTP(smtp_server, 25)
  # server.set_debuglevel(1) # 记录详细信息
  server.login(from_addr, password) # 登录邮箱服务器
  server.sendmail(from_addr, to_addr, msg.as_string()) # 发送信息
  server.quit()
  print("带图片邮件发送成功！")
 except Exception as e:
  print("发送失败：" + e)

3 发送带图片附件的邮件

'''发送带图片附件的邮件'''
def sendFilesEmail(from_addr,password,to_addr,smtp_server):
 try:
  msg = MIMEMultipart()
  msg['From'] = _format_addr('信息化工程所 <%s>' % from_addr)
  msg['To'] = _format_addr('收件人 <%s>' % to_addr)
  msg['Subject'] = Header('邮件的主题：问候', 'utf-8').encode()
  # 邮件正文是MIMEText:
  msg.attach(MIMEText('发送多附件邮件...', 'plain', 'utf-8'))
  #---这是附件部分---
  #xlsx类型附件
  part = MIMEApplication(open(r'./file/foo.xlsx','rb').read())
  part.add_header('Content-Disposition', 'attachment', filename="foo.xlsx")
  msg.attach(part)
  #jpg类型附件
  part = MIMEApplication(open(r'./file/图片.png','rb').read())
  part.add_header('Content-Disposition', 'attachment', filename=('gbk', '', '图片.png'))
  msg.attach(part)
  #pdf类型附件
  part = MIMEApplication(open(r'./file/foo.pdf','rb').read())
  part.add_header('Content-Disposition', 'attachment', filename="foo.pdf")
  msg.attach(part)
  # #mp3类型附件
  # part = MIMEApplication(open('foo.mp3','rb').read())
  # part.add_header('Content-Disposition', 'attachment', filename="foo.mp3")
  # msg.attach(part)
  server = smtplib.SMTP(smtp_server, 25,timeout=30)
  # server.set_debuglevel(1) # 记录详细信息
  server.login(from_addr, password) # 登录邮箱服务器
  server.sendmail(from_addr, to_addr, msg.as_string()) # 发送信息
  server.quit()
  print("带图片邮件发送成功！")
 except Exception as e:
  print("发送失败：" + e)
