这篇文章将为大家详细讲解有关利用python实现发送带附件的邮件，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
具体代码如下：
from django.template import loader from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.header import Header import smtplib import traceback class SendEmail(object): """ 发送html邮件 """ def __init__(self, mail_host, mail_port, mail_user, mail_pass, sender, to_list_email): # 创建邮件对象 self.msg = MIMEMultipart() # 邮箱服务地址 self.mail_host = mail_host # 邮箱端口号 self.mail_port = mail_port # 邮箱账号 self.mail_user = mail_user # 密码 self.mail_pass = mail_pass # 发送人 self.sender = sender # 收件人邮箱列表 self.to_list_email = to_list_email def make_html(self, base_html_path, **kwargs): """ :param base_html_path: html模板文件路径 :param **kwargs: 模板中的参数 :return: """ mail_html = loader.render_to_string( template_name=base_html_path, context={ # "id": tid, **kwargs # 传入模板文件的数据 } ) return mail_html def add_attachment(self, file_path): """ 制作附件 :param file_path: :return: """ with open(file_path, 'rb') as f: content = f.read() att = MIMEText(content, _subtype='plain', _charset='utf-8') att["Content-Type"] = 'application/octet-stream' att["Content-Disposition"] = 'attachment; filename=task_report.docx' att.add_header("Content-Disposition", "attachment", filename=("gbk", "", "{}".format(filename))) # 如果文件名中有中文的话需设置 return att def send_html_email(self, base_html_path, subject, str_to, str_cc, file_path, **kwargs): """ :param html: html文件对象 :param subject: 邮件主题 :return: """ html = self.make_html(base_html_path, **kwargs) self.msg.attach(MIMEText(str(html), 'html')) self.msg['from'] = Header('安全测试平台', 'utf-8') self.msg['Subject'] = Header(subject, 'utf-8') self.msg["Accept-Language"] = "zh-CN" self.msg["Accept-Charset"] = "ISO-8859-1,utf-8" self.msg['to'] = str_to # 发送人 str self.msg['cc'] = str_cc # 抄送人 str # 添加附件 att = self.add_attachment(file_path) self.msg.attach(att) # 发送邮件 try: server = smtplib.SMTP() server.connect(self.mail_host, self.mail_port) server.login(self.mail_user, self.mail_pass) server.sendmail(self.sender, self.to_list_email, self.msg.as_string()) server.quit() except Exception: print(traceback.format_exc())内容扩展：
实例二：
import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.application import MIMEApplication """ 发送带附件邮件的完整代码 """ class HandleEmail(): def handle_email(self): # step1 连接smtp服务器并登陆 smtp = smtplib.SMTP_SSL(host='smtp.qq.com', port=465) smtp.login(user='XXXXX@qq.com', password='XXXXX') # 构造多组件邮件并完善邮件描述性信息 msg = MIMEMultipart() msg['Subject'] = '带附件的邮件-01' msg['FROM'] = 'XXXXXX@qq.com' msg['To'] = 'XXXXX@163.com' # 添加邮件的文本内容 text = MIMEText(_text='这是邮件正文的内容', _charset='UTF8') msg.attach(text) # 添加附件和附件header with open(file=r'XXXXXXXX\report.html', mode='rb') as f: content = f.read() attachment = MIMEApplication(_data=content) attachment.add_header('content-disposition', 'attachment', filename='report.html') msg.attach(attachment) # 发送邮件 smtp.send_message(msg=msg, from_addr='XXXXXXX@qq.com', to_addrs='XXXXX@163.com') if __name__ == '__main__': e_mail = HandleEmail() e_mail.handle_email()
使用创建好的smtp对象发送邮件，需要把上面编辑好的msg作为参数传入，然后填写收发件人，如果有多个收件人，以列表的形式传入参数
smtp.send_message(msg=msg,from_addr='',to_addrs='') # 单个收件人 smtp.send_message(msg=msg,from_addr='',to_addrs=['收件人一','收件人二']) # 多个收件人
