Python3 notes

在 HTML 文本中添加图片

邮件的 HTML 文本中一般邮件服务商添加外链是无效的，正确添加图片的实例如下所示：

实例

#!/usr/bin/python3

import smtplib

from email.mime.image import MIMEImage

from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText

from email.header import Header

sender = 'from@runoob.com'

receivers = ['429240967@qq.com']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

msgRoot = MIMEMultipart('related')

msgRoot['From'] = Header("菜鸟教程", 'utf-8')

msgRoot['To'] =  Header("测试", 'utf-8')

subject = 'Python SMTP 邮件测试'

msgRoot['Subject'] = Header(subject, 'utf-8')

msgAlternative = MIMEMultipart('alternative')

msgRoot.attach(msgAlternative)

mail_msg = """

Python 邮件发送测试...

图片演示：

"""

msgAlternative.attach(MIMEText(mail_msg, 'html', 'utf-8'))

# 指定图片为当前目录

fp = open('test.png', 'rb')

msgImage = MIMEImage(fp.read())

fp.close()

# 定义图片 ID，在 HTML 文本中引用

msgImage.add_header('Content-ID', '')

msgRoot.attach(msgImage)

try:

   smtpObj = smtplib.SMTP('localhost')

   smtpObj.sendmail(sender, receivers, msgRoot.as_string())

   print ("邮件发送成功")

except smtplib.SMTPException:

   print ("Error: 无法发送邮件")

$ python3 test.py  

邮件发送成功
