[Python] 发送Email (可发HTML，附件）-优快云博客

在Python里我们可以使用smtplib模块发送email，smtp(Simple Mail Transfer Protocal），是简单邮件传输协议，通过它可以和smtp server进行通讯。

smtplib的一个简单例子

import smtplib
"""The first step is to create an SMTP object, each object is used for connection with one server."""
server = smtplib.SMTP('smtp.163.com','994')
 
#Next, log in to the server
server.login("username","password")
 
#Send the mail
msg = "\nHello!" # The \n separates the message from the headers
server.sendmail("from@163.com", "to@gmail.com", msg)

首先你要获得邮件服务器的smtp地址和端口号，一般都能在网上找到，然后输入你邮箱的用户名和密码，编辑邮件标题和正文（它们之间用\n隔开），最后指定目标邮件地址发送邮件。

使用Email Package

Python里有两个模块：MIMEMultipart和MIMEText，我们可以利用它们构造和解析邮件信息。

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

#First, we compose some of the basic message headers:
fromaddr = "from@163.com"
toaddr = "to@gmail.com"
ccaddr = "cc@gmail.com"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Cc'] = ccaddr
msg['Subject'] = "Python email"

#Next, we attach the body of the email to the MIME message:
body = "Python test mail"
msg.attach(MIMEText(body, 'plain'))

'''For sending the mail, we have to convert the object to a string, and then
use the same prodecure as above to send using the SMTP server..'''

server = smtplib.SMTP('smtp.163.com','994')

server.login("username","password")

text = msg.as_string()server.sendmail(fromaddr, toaddr, text)

上面这个例子发送了一个纯文本信息(Plain),如果有发送html邮件，可以参考如下例子：

body = "<a href='http://blog.youkuaiyun.com/u010415792'>Zhu_Julian's Blog</a>"
msg.attach(MIMEText(body, 'html'))

如果要发送附件，只要把附件attach到msg实例即可：

#Attach an attachment
att = MIMEText(open(r'c:\123.txt', 'rb').read(), 'base64', 'gb2312')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="123.txt'
msg.attach(att)

Send Email模板

def sendemail(from_addr, to_addr_list, cc_addr_list,
       subject, username, password, msg_content,
       msg_type='plain', attachment=None):
  #First, we compose some of the basic message headers:
  msg = MIMEMultipart()
  msg['From'] = from_addr
  msg['To'] = to_addr_list
  msg['Cc'] = cc_addr_list
  msg['Subject'] = subject 
 
  msg_type = msg_type.lower()
  if msg_type == 'plain':
    msg.attach(MIMEText(msg_content, 'plain'))
  elif mst_type == 'html':
    msg.attach(MIMEText(msg_content, 'html'))
  else:
    return false
 
  #Attach an attachment
  if attachment is not None:
    att = MIMEText(open(attachment, 'rb').read(), 'base64', 'gb2312')
    att["Content-Type"] = 'application/octet-stream'
    att.add_header("Content-Disposition", "attachment", filename = os.path.basename(attachment))
    msg.attach(att)  


  server = smtplib.SMTP('atom.corp.ebay.com')
  text = msg.as_string()
  server.sendmail(from_addr, to_addr_list, text)

下面是调用上面模板的客户端：

sendemail(from_addr = 'xianzhu@ebay.com', 
          to_addr_list = 'xianzhu@ebay.com, xianzhu@ebay.com', 
          cc_addr_list = 'xianzhu@ebay.com',
          subject = 'subject', 
          username = 'username',
          password = 'password'
          msg_content = 'content', 
          msg_type='plain',  
          attachment=r'C:\123.txt')
