【python】用SMTP模块发送带附件

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage
#全部为python内置，不需要安装第三方模块
receivers = ["receivers@163.com"]
sender = "sender@163.com"
mail_pass = "password"
mail_subject = "python发送邮件测试"         # 邮件的标题
mail_context = "这是邮件内容"


msg = MIMEMultipart()
msg["From"] = sender  # 发件人
msg["To"] = ";".join(receivers)  # 收件人
msg["Subject"] = mail_subject   # 邮件标题
# 邮件正文
msg.attach(MIMEText(mail_context, 'plain', 'utf-8'))
#图片附件
#不同的目录下要写全文件路径
with open('test.jpg','rb') as picAtt:
    msgImg = MIMEImage(picAtt.read())
    msgImg.add_header('Content-Disposition', 'attachment', filename='你.jpg')
    #msgImg.add_header('Content-ID', '<0>')
    #msgImg.add_header('X-Attachment-Id', '0')
    msg.attach(msgImg)
# 构造附件
att = MIMEText(open('test.txt', "rb").read(), "base64", "utf-8")
att["Content-Type"] = "application/octet-stream"
# 附件名称为中文时的写法
att.add_header("Content-Disposition", "attachment", filename=("gbk", "", "测试结果.txt"))
# 附件名称非中文时的写法
# att["Content-Disposition"] = 'attachment; filename="test.html")'
