本文以实例形式展示了Python发送Email功能的实现方法，有不错的实用价值的技巧，且功能较为完善。具体实现方法如下：

主要功能代码如下：

#/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"%(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()

希望本文所述实例对大家的Python程序设计有一定的帮助。
