subject1 = "给XXX的一封信"
body = '<p>我们约会吧</p>'             # 邮件正文用html格式
msg = MIMEText(body, "html", "utf-8")

msg['subject'] = subject1
# -----------2、2发送附件-------------------

subject2 = "给帅哥的一张图片"
file_path = "E:\test_demo\report\report.html"
with open(file_path, "rb") as fp:
    mail_body = fp.read()
msg = MIMEMultipart()
msg["from"] = sender                     # 发件人
msg["to"] = receiver                     # 收件人
