这篇文章主要为大家详细介绍了python实现发送邮件及附件功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
今天给大伙说说python发送邮件，官方的多余的话自己去百度好了，还有一大堆文档说实话不到万不得已的时候一般人都不会去看，回归主题：
本人是mac如果没有按照依赖模块的请按照下面的截图安装
导入模块如果没有错误，表示已经安装成功。
python发送一个未知mime类型的文件附件其基本思路如下：
1. 构造mimemultipart对象做为根容器
2. 构造mimetext对象做为邮件显示内容并附加到根容器
3. 构造mimebase对象做为文件附件内容并附加到根容器
a. 读入文件内容并格式化
b. 设置附件头
4. 设置根容器属性
5. 得到格式化后的完整文本
6. 用smtp发送邮件
实例代码：
#!/usr/bin/env python # -*- coding:utf-8 -*- import smtplib from email.mime.multipart import mimemultipart from email.mime.text import mimetext from email.mime.application import mimeapplication class mailer(object): def init(self,maillist,mailtitle,mailcontent): self.mail_list = maillist self.mail_title = mailtitle self.mail_content = mailcontent self.mail_host = "smtp.163.com" self.mail_user = "your email name" self.mail_pass = "your email password" self.mail_postfix = "163.com" def sendmail(self): me = self.mail_user + "<" + self.mail_user + "@" + self.mail_postfix + ">" msg = mimemultipart() msg['subject'] = 'python mail test' msg['from'] = me msg['to'] = ";".join(self.mail_list) #puretext = mimetext('<h1>你好，<br/>'+self.mail_content+'</h1>','html','utf-8') puretext = mimetext('纯文本内容'+self.mail_content) msg.attach(puretext) # jpg类型的附件 jpgpart = mimeapplication(open('/home/mypan/1949777163775279642.jpg', 'rb').read()) jpgpart.add_header('content-disposition', 'attachment', filename='beauty.jpg') msg.attach(jpgpart) # 首先是xlsx类型的附件 #xlsxpart = mimeapplication(open('test.xlsx', 'rb').read()) #xlsxpart.add_header('content-disposition', 'attachment', filename='test.xlsx') #msg.attach(xlsxpart) # mp3类型的附件 #mp3part = mimeapplication(open('kenny.mp3', 'rb').read()) #mp3part.add_header('content-disposition', 'attachment', filename='benny.mp3') #msg.attach(mp3part) # pdf类型附件 #part = mimeapplication(open('foo.pdf', 'rb').read()) #part.add_header('content-disposition', 'attachment', filename="foo.pdf") #msg.attach(part) try: s = smtplib.smtp() #创建邮件服务器对象 s.connect(self.mail_host) #连接到指定的smtp服务器。参数分别表示smpt主机和端口 s.login(self.mail_user, self.mail_pass) #登录到你邮箱 s.sendmail(me, self.mail_list, msg.as_string()) #发送内容 s.close() return true except exception, e: print str(e) return false if name == 'main': #send list mailto_list = ["aaa@lsh123.com","bbb@163.com"] mail_title = 'hey subject' mail_content = 'hey this is content' mm = mailer(mailto_list,mail_title,mail_content) res = mm.sendmail() print res
以上就是python中如何实现发送邮件及附件功能的具体详解的详细内容。
