Python通过电子邮件发送的Zip存档未正确显示

Question

我有一个程序，每天自动发送报告给我自己和其他一些人。这些报告被写入my /tmp/目录中的一个文件夹，然后压缩成Zip存档并作为附件通过电子邮件发送。我希望所有用户都能看到附件Reports_2017-06-20.zip（或者当天的日期）。在我的电子邮件客户端上，我看到附件为_tmp_Engineering_Reports_2017-06-20.zip。报告的一位收件人声称，附件只出现在他的电子邮件客户端2。在所有情况下，文件都是通过电子邮件成功传输的，但是zip文件通常必须由最终用户手动重命名才能提取文件并查看它们。下面是我的电子邮件课程。字典passed_values是在这个类之外创建的。正在传递的filename是/tmp/Reports_2017-06-20

    def send_email_with_attachment(self):
        msg = MIMEMultipart()
        msg['From'] = self._from_address
        msg['To'] = ', '.join(self._to_addresses)
        msg['Subject'] = self._subject
        msg.attach(MIMEText(self._body, 'plain'))
        attachment = open (self._filename + '.zip', "rb")
        part = MIMEBase('application', 'octet-stream')
        part.set_payload(attachment.read())
        encoders.encode_base64(part)
        part.add_header('Content-Disposition', "attachment; filename= %s" % self._filename + '.zip')
        msg.attach(part)
        server = smtplib.SMTP('smtp.gmail.com', 587)
        server.starttls()
        server.login(self._from_address, self._email_password)
        text = msg.as_string()
        server.sendmail(self._from_address, self._to_addresses, text)
        server.quit()

有人能告诉我我做错了什么吗

使用os.path.basename以便只发送Content-Disposition头中的文件名（而不是完整路径）。似乎电子邮件客户端不确定如何处理包含斜杠的“文件名”
