python使用smtplib发送邮件

使用第三方 SMTP 服务发送

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr
 
my_sender='429240967@qq.com'    # 发件人邮箱账号
my_pass = 'xxxxxxxxxx'              # 发件人邮箱密码
my_user='429240967@qq.com'      # 收件人邮箱账号，我这边发送给自己
def mail():
    ret=True
    try:
        msg=MIMEText('填写邮件内容','plain','utf-8')
        msg['From']=formataddr(["FromRunoob",my_sender])  # 括号里的对应发件人邮箱昵称、发件人邮箱账号
        msg['To']=formataddr(["FK",my_user])              # 括号里的对应收件人邮箱昵称、收件人邮箱账号
        msg['Subject']="菜鸟教程发送邮件测试"                # 邮件的主题，也可以说是标题
 
        server=smtplib.SMTP_SSL("smtp.qq.com", 465)  # 发件人邮箱中的SMTP服务器，端口是25
        server.login(my_sender, my_pass)  # 括号中对应的是发件人邮箱账号、邮箱密码
        server.sendmail(my_sender,[my_user,],msg.as_string())  # 括号中对应的是发件人邮箱账号、收件人邮箱账号、发送邮件
        server.quit()  # 关闭连接
    except Exception:  # 如果 try 中的语句没有执行，则会执行下面的 ret=False
        ret=False
    return ret
 
ret=mail()
if ret:
    print("邮件发送成功")
else:
    print("邮件发送失败")

发送HTML内容并在 HTML 文本中添加图片

#!/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 = '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 = """
<p>Python 邮件发送测试...</p>
<p><a href="http://www.runoob.com">菜鸟教程链接</a></p>
<p>图片演示：</p>
<p><img src="cid:image1"></p>
"""
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', '<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"
