• 利用python的组件进行发邮件
  1.构建邮件服务器设置、连接服务器、登录服务器
  2.构建邮件内容
  3.发送邮件，收件人收件
  步骤1、2通过smtplib实现，步骤3通过email实现

代码片段：构建邮件服务、发邮件
  # 构建smtp对象
   smtp = smtplib.SMTP()

    # 连接到smtp服务
    smtp.connect(self.smtp_server, self.stmp_port)

    # 登录smtp服务
    smtp.login(self.sender, self.password)

    # 发送邮件
    print('收件人为：', self.reveiver)
    res = smtp.sendmail(self.sender, self.reveiver, msg.as_string())
    print("邮件发送结果： ", res)

    # 退出
    smtp.quit()
    print("send email finish")

• 构建邮件内容
  邮件内容的构建大致为文本内容、html格式、附件、图片四种需求
  使用到的包文件为：
  from email.mime.text import MIMEText
  from email.mime.image import MIMEImage
  from email.mime.multipart import MIMEMultipart

代码片段：
 def __content_of_email(self, msg_type):
        """
        邮件正文为文本内容
        :param content:
        :return:
        """
        msg = MIMEMultipart()
        msg["From"] = self.sender
        msg["To"] = ";".join(self.reveiver)
        msg['Subject'] = Header(self.subject, "utf-8")

        # 如果msg为plain,则邮件正文为文本
        if msg_type == 'plain':
            msg.attach(MIMEText(self.content, "plain", "utf-8"))
        # 如果msg为html,则邮件正文为html
        elif msg_type == "html":
            msg.attach(MIMEText(self.content, "html", "utf-8"))
        else:
            print("邮件内容类型不正确")

        if self.attachment is not None:

            # 读取附件内容
            with open(attachment, 'r')as f:
                contents = f.read()
            # 设置html格式参数
            html_content = MIMEText(contents, 'base64', 'utf-8')
            html_content["Content-Type"] = 'application/octet-stream'
            html_content.add_header("Content-Disposition", "attachment", filename=os.path.basename(attachment))
            msg.attach(html_content)

        return msg
