【转】python3 发邮件实例（包括：文本、html、图片、附件、SSL、群邮件）

特别留意群邮件方式，这是工作中用得多的。

附件，HTML，图片，都需要的。

文件形式的邮件

[python]  view plain copy

4.from email.mime.text import MIMEText
5.from email.header import Header
6.
7.sender = '***'
8.receiver = '***'
9.subject = 'python email test'
10.smtpserver = 'smtp.163.com'
11.username = '***'
12.password = '***'
13.
14.msg = MIMEText('你好','plain','utf-8')#中文需参数‘utf-8’，单字节字符不需要
15.msg['Subject'] = Header(subject, 'utf-8')
16.
17.smtp = smtplib.SMTP()
18.smtp.connect('smtp.163.com')
19.smtp.login(username, password)
20.smtp.sendmail(sender, receiver, msg.as_string())
21.smtp.quit()

11.smtpserver = 'smtp.163.com'
12.username = '***'
13.password = '***'
14.
15.# Create message container - the correct MIME type is multipart/alternative.
16.msg = MIMEMultipart('alternative')
17.msg['Subject'] = "Link"
18.
19.# Create the body of the message (a plain-text and an HTML version).

31."""
32.
33.# Record the MIME types of both parts - text/plain and text/html.
34.part1 = MIMEText(text, 'plain')
35.part2 = MIMEText(html, 'html')
36.
37.# Attach parts into message container.
38.# According to RFC 2046, the last part of a multipart message, in this case
39.# the HTML message, is best and preferred.
40.msg.attach(part1)
41.msg.attach(part2)
42.#构造附件
43.att = MIMEText(open('h:\\python\\1.jpg', 'rb').read(), 'base64', 'utf-8')

3.import smtplib
4.from email.mime.text import MIMEText
5.from email.header import Header
6.sender = '***'
7.receiver = '***'
8.subject = 'python email test'
9.smtpserver = 'smtp.163.com'
10.username = '***'
11.password = '***'
12.
13.msg = MIMEText('你好','plain','utf-8')#中文需参数‘utf-8’，单字节字符不需要
14.msg['Subject'] = Header(subject, 'utf-8')
15.
16.smtp = smtplib.SMTP()
17.smtp.connect('smtp.163.com')
