python发送图文邮件 html和图片的邮件代码

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/python
# -*- coding: UTF-8 -*-
 
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 = 'web@zzzyk.com'
receivers = ['你的qq@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("站长资源库", '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 = """
<p>Python 邮件发送测试...</p>
<p><a href="http://www.zzzyk.com">站长资源库</a></p>
<p>图片演示：</p>
<p><img decoding="async" src="cid:image1"></p>
"""
msgAlternative.attach(MIMEText(mail_msg, 'html', 'utf-8'))
 
# 指定图片为当前目录
fp = open('zzzyk.com.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', '<image1>')
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"
