发送普通文本邮件

# import unittest

#         smtpObj.sendmail(sender, receivers, message.as_string())
#         print("邮件发送成功")
#     except smtplib.SMTPException:
#         print("Error: 无法发送邮件")
#

发送html格式的邮件

只需将MIMEText的第二个参数的文本类型改一下即可

# import smtplib
# from email.mime.text import MIMEText
# from email.header import Header
#
# # 第三方 SMTP 服务
#
# mail_host = "smtp.qq.com"  # 设置服务器
# mail_user = "2609768410@qq.com"  # 用户名
# mail_pass = "vhxojjnwatpvebcf"  # 获取授权码
# sender = '2609768410@qq.com'  # 发件人账号
# receivers = ['2609768410@qq.com']  # 接收邮件(可以多个)，可设置为你的QQ邮箱或者其他邮箱
#
# send_content = """
# <h1>天不生我李淳罡</h1>
# <h1>剑道万古如长夜</h1>

发送带附件的邮件
首先要创建MIMEMultipart实例，然后在构建附件，如果有多个附件的话，可依次构建，最后利用smtplib.smtp发送

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header

# 第三方 SMTP 服务
mail_host = "smtp.qq.com"  # 设置服务器
mail_user = "2609768410@qq.com"  # 用户名
mail_pass = "vhxojjnwatpvebcf"  # 获取授权码
sender = '2609768410@qq.com'  # 发件人账号
receivers = ['2609768410@qq.com']  # 接收邮件(可以多个)，可设置为你的QQ邮箱或者其他邮箱
# 创建一个带附件的实例
message = MIMEMultipart()
message['From'] = Header("我是发件人", 'utf-8')  # 发件人
message['To'] = Header("我是收件人", 'utf-8')   # 收件人

subject = 'Python发送带附件的邮件示例'
message['Subject'] = Header(subject, 'utf-8')

# 邮件正文内容
send_content = 'hi man，你收到附件了吗？'
content_obj = MIMEText(send_content, 'plain', 'utf-8')  # 第一个参数为邮件内容
message.attach(content_obj)

# 构造附件，发送目录下的 report_day14.html 文件
att2 = MIMEText(open('../report/report_day14.html', 'rb').read(), 'base64', 'utf-8')
att2["Content-Type"] = 'application/octet-stream'
att2["Content-Disposition"] = 'attachment; filename="report_day14.html"'
message.attach(att2)
try:
    smtpObj = smtplib.SMTP()
    smtpObj.connect(mail_host, 25)  # 25 为 SMTP 端口号
    smtpObj.login(mail_user, mail_pass)
    smtpObj.sendmail(sender, receivers, message.as_string())
    print("邮件发送成功")

except smtplib.SMTPException:
    print("Error: 无法发送邮件")
