Python のメール送信メソッドの例

この記事では、Python のメール送信機能の実装方法をサンプル形式で示します。実用価値が高く、機能も比較的充実しています。具体的な実装方法は以下の通りです。

主な機能コードは次のとおりです:

#/usr/bin/env python
# -*- encoding=utf-8 -*-

import base64
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

class CCSendMail:
  def __init__(self,host="your.mailhost.com",username='fromuser@xxx.com',password='passwd'):
    self.__smtp=smtplib.SMTP(host)
    self.__subject=None
    self.__content=None
    self.__from=None
    self.__to=[]
    self.__style='html'
    self.__charset='gb2312'
    self.username = username
    self.password = password
    self.fromAlias='fromuser' #发件人别名
    self.from2=''
    
  def close(self):
    try:
      self.__smtp.quit()
    except Exception ,e:
      pass  
  def setFromAlias(self,alias):
    self.fromAlias=alias
  def setStyle(self,style):
    self.__style = style
  def setFrom2(self,from2):
    self.from2=from2
    
  def setSubject(self,subject):
    self.__subject=subject
    
  def setContent(self,content):
    self.__content=content
    
  def setFrom(self,address):
    self.__from=address
    
  def addTo(self,address):
    self.__to.append(address)
    
  def setCharset(self,charset):
    self.__charset=charset
    
  def send(self):
    try:
      self.__smtp.set_debuglevel(1)
      
      #login if necessary
      if self.username and self.password:
        self.__smtp.login(self.username,self.password)
        
      msgRoot = MIMEMultipart('related')
      msgRoot['Subject'] = self.__subject
      aliasB6=base64.encodestring(self.fromAlias.encode(self.__charset))
      if len(self.from2)==0:
        msgRoot['From'] = "=?%s?B?%s?=%s"%(self.__charset,aliasB6.strip(),self.__from)
      else:
        msgRoot['From'] = "%s"%(self.from2)
      msgRoot['To'] = ";".join(self.__to)
      
      msgAlternative = MIMEMultipart('alternative')
      msgRoot.attach(msgAlternative)
      
      msgText = MIMEText(self.__content, self.__style,self.__charset)
      msgAlternative.attach(msgText)

      self.__smtp.sendmail(self.__from,self.__to,msgRoot.as_string())
      return True
    except Exception,e:
      print "Error ",e
      return False
    
  def clearRecipient(self):
    self.__to = []
  
  #给单个人发送邮件
  def sendHtml(self,address,title,content):
    self.setStyle('html')
    self.setFrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    self.addTo(address)
    self.setSubject(title)
    self.setContent(content)
    ret = self.send()
    self.close()
    return ret
  
  #群发邮件
  def sendMoreHtml(self,addressList,title,content):
    self.setStyle('html')
    self.setFrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    for address in addressList:
      self.addTo(address)
    self.setSubject(title)
    self.setContent(content)
    ret = self.send()
    self.close()
    return ret

#测试
def main():
  send=CCSendMail()
  send.sendHtml('touser@xxx.com',u'邮件标题',u'邮件内容')
  #send.sendMoreHtml([touser1@xx.com,touser2@xx.com],u'邮件标题',u'邮件内容')
 
if __name__=='__main__':
  main()
