文件形式的邮件

复制代码 代码如下:

#!/usr/bin/env python3  
#coding: utf-8  
import smtplib  
from email.mime.text import mimetext  
from email.header import header  

sender = '***'  
receiver = '***'  
subject = 'python email test'  
smtpserver = 'smtp.163.com'  
username = '***'  
password = '***'  

msg = mimetext('你好','text','utf-8')#中文需参数‘utf-8'，单字节字符不需要  
msg['subject'] = header(subject, 'utf-8')  

smtp = smtplib.smtp()  
smtp.connect('smtp.163.com')  
smtp.login(username, password)  
smtp.sendmail(sender, receiver, msg.as_string())  
smtp.quit()  

html形式的邮件

复制代码 代码如下:

#!/usr/bin/env python3
#coding: utf-8
import smtplib

smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = mimetext('<html><h1>你好</h1></html>','html','utf-8')

msg['subject'] = subject

smtp = smtplib.smtp()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

带图片的html邮件

subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msgroot = mimemultipart('related')
msgroot['subject'] = 'test message'

msgtext = mimetext('<b>some <i>html</i> text</b> and an image.<br><img src="cid:image1"><br>good!','html','utf-8')
msgroot.attach(msgtext)

fp = open('h:\\python\\1.jpg', 'rb')
msgimage = mimeimage(fp.read())
fp.close()

msgimage.add_header('content-id', '<image1>')
msgroot.attach(msgimage)

smtp = smtplib.smtp()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msgroot.as_string())
smtp.quit()

subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msgroot = mimemultipart('related')
msgroot['subject'] = 'test message'

#构造附件
att = mimetext(open('h:\\python\\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["content-type"] = 'application/octet-stream'
att["content-disposition"] = 'attachment; filename="1.jpg"'
msgroot.attach(att)

smtp = smtplib.smtp()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msgroot.as_string())
smtp.quit()

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

# create message container - the correct mime type is multipart/alternative.
msg = mimemultipart('alternative')
msg['subject'] = "link"

# create the body of the message (a plain-text and an html version).
text = "hi!\nhow are you?\nhere is the link you wanted:\nhttp://www.python.org"
html = """\
<html>
  <head></head>
  <body>
    <p>hi!<br>
       how are you?<br>
       here is the <a href="http://www.python.org">link</a> you wanted.
    </p>
  </body>
</html>
"""

# record the mime types of both parts - text/plain and text/html.
part1 = mimetext(text, 'plain')
part2 = mimetext(html, 'html')

# attach parts into message container.
# according to rfc 2046, the last part of a multipart message, in this case
# the html message, is best and preferred.
msg.attach(part1)
msg.attach(part2)
#构造附件
att = mimetext(open('h:\\python\\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["content-type"] = 'application/octet-stream'
att["content-disposition"] = 'attachment; filename="1.jpg"'
msg.attach(att)

smtp = smtplib.smtp()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

基于ssl的邮件

复制代码 代码如下:

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import mimetext
from email.header import header

receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = mimetext('你好','plain','utf-8')#中文需参数‘utf-8'，单字节字符不需要
msg['subject'] = header(subject, 'utf-8')

smtp = smtplib.smtp()
smtp.connect('smtp.163.com')
smtp.ehlo()
smtp.starttls()
smtp.ehlo()
smtp.set_debuglevel(1)
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
