python smtplib模块发邮件(带附件)的例子

#!/bin/python
#coding=utf-8
import smtplib
from email.mime.text import MIMEText

sender = 'your@email'
mailto = 'target@email'

#邮件信息
msg =MIMEText("It's a text email!")
msg['Subject'] = 'Hello world'
msg['to'] = mailto
msg['From'] = sender

#连接发送服务器
smtp = smtplib.SMTP('smtp.xxx.xxx')
smtp.login(username,password)

#发送
smtp.sendmail(sender,mailto,msg.as_string())
smtp.quit()
类MIMEText()：用来生成text/* 类型的MIME邮件主体对象，完整参数格式是：MIMEText(_text, _subtype=’plain’, _charset=’us-ascii’)

_text：字符型的邮件内容对象；
_subtype：MIME内容类型，默认为“普通”，如：MIMEText（text,’html’）指html格式的邮件内容；
_charset：指定的字符集，如utf-8

#!/bin/python
#coding=utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

sender = 'your@email'
mailto = 'target@email'
imgfiles = 'text_1.png'

msg = MIMEMultipart()
msg['Subject'] = 'Test send image!'
msg['To'] = mailto
msg['From'] = sender

# 邮件内容
Contents = MIMEText('<b>This is a img!</b>','html')
msg.attach(Contents)

# 带上二进制附件 
att = MIMEImage(file(imgfiles, 'rb').read()) 
att["Content-Type"] = 'application/octet-stream' 
att.add_header('content-disposition','attachment',filename=imgfiles)
msg.attach(att)

# 登录邮件发送服务器
smtp = smtplib.SMTP('smtp.xxx.xxx')
smtp.login(username,password)

# 发送邮件
smtp.sendmail(sender, mailto, msg.as_string())
smtp.quit()

imgData = MIMEImage(file(imgfiles, 'rb').read())
imgData.add_header('Content-ID', '<%s>'% imgfiles)
msg.attach(imgData )

contents = MIMEText('<img src="cid:%s">'% imgfiles,'html')
msg.attach(contents)
