使用 Python 3.x 发送带有 docx 附件的 email

Question

我正在使用 python 和 Gmail （在 Gmail 上的已发送文件夹中显示它）发送 email 到我的 Yahoo Z0C83F57C7873A07B4A3 附件的地址。

一切似乎都正常，除了当它到达 Gmail 时，它的附件文件名带有__io.BufferedReader name='myfile.docx'_

原始消息到达目的地雅虎显示：

Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename= <_io.BufferedReader name='myfile.docx'>

如何修复它，使文件名没有<_io.BufferedReader...等？ 我猜它正在修复 header？ 另外，为什么content-transfer-encoding:base64在 header 中重复？

        subject = "this is the subject line"
        message = MIMEMultipart()
        message["Subject"] = subject
        message["From"] = sender_email
        message["To"] = receiver_email

        body = 'This is the body of the email'

        message.attach(MIMEText(body))

        attach_file = open("myfile.docx", 'rb') # Open the file as binary mode

        payload = MIMEApplication(attach_file.read(),
                        'vnd.openxmlformats-officedocument.wordprocessingml.document')

        encoders.encode_base64(payload)

        payload.add_header('Content-Disposition',
                            "attachment; filename= %s" % attach_file)

        message.attach(payload)

#for SSL 465 port - wont work yet on gmx but works on gmail

        context = ssl.create_default_context()

        with smtplib.SMTP_SSL(smtp_server, port,context=context) as server:

            try:
#                server.ehlo()  this is for not needed for gmail but is for gmx TLS
#                server.starttls() this is not needed for gmail SSL but is for gmx TLS 
                server.login(sender_email, password)
                server.sendmail(sender_email, receiver_email, message.as_string())
                self.statusBar().showMessage('Email Sent.')
                server.quit()

            except smtplib.SMTPAuthenticationError:
                self.statusBar().showMessage('Email Not Sent. Authentication Failure.')
                server.quit()

            except Exception as e:  # pylint: disable=broad-except
                self.statusBar().showMessage(f"SMTP exception {e}")
                server.quit()

好的，我自己修好了，又一次。 太简单了，可惜我错过了。 无论如何，如果您在将 NO NAME 作为附件（或 __io.BufferedReader name='myfile.docx'_）时遇到问题，则在添加时只需将 add.name 添加到附件文件名的末尾header。 并不是说我可以在这里看到很多带有该参考的示例。 最新版本也不需要专门调用编码器，否则您将在原始 header 中获得双重“编码”。

#       encoders.encode_base64(payload)
# already encoded, so didn't need this line above
        payload.add_header('Content-Disposition',
                           'attachment',filename='%s' % attach_file.name)
