主机在使用 Gmail API 和 Python 发送电子邮件时中止连接

Question

我不会用整个代码来打扰你 - 这是我的第一个问题所以请耐心等待。

我正在尝试使用 Gmail API 发送附有 .zip 文件的电子邮件。整个想法是通过 Gmail 自动发送带有数据的电子邮件，同时保持标准的安全级别。

这是我的身份验证方式：

def authenticate(self):
        CLIENT_SECRET_FILE = 'client_secrets.json'
        OAUTH_SCOPE = 'https://www.googleapis.com/auth/gmail.compose'
        STORAGE = Storage('gmail.storage')
        flow = flow_from_clientsecrets(CLIENT_SECRET_FILE, scope=OAUTH_SCOPE)
        http = httplib2.Http()
        credentials = STORAGE.get()
        if credentials is None or credentials.invalid:
            credentials = run(flow, STORAGE, http=http)
        http = credentials.authorize(http)
        self.service = build('gmail', 'v1', http=http)

然后使用 Google 给出的例子，几乎原样，我准备我的消息：

def CreateMessageWithAttachment(self, sender, to, subject, message_text, file_strings):
        message = MIMEMultipart()
        message['to'] = to
        message['from'] = sender
        message['subject'] = subject

        msg = MIMEText(message_text)
        message.attach(msg)

        for path in file_strings:
            content_type, encoding = mimetypes.guess_type(path)

            main_type, sub_type = content_type.split('/', 1)
            fp = open(path, 'rb')
            msg = MIMEBase(main_type, sub_type)
            msg.set_payload(fp.read())
            fp.close()
            msg.add_header('Content-Disposition', 'attachment', filename=path.split("\")[-1])
            message.attach(msg)

        return  {'raw': base64.urlsafe_b64encode(message.as_string())}

最后我再次使用几乎完全相同的示例发送它：

 def SendMessage(self, message, address):
        try:
            message = (self.service.users().messages().send(userId=self.user_id, body=message).execute())
            return "Message to %s successfuly sent at: %s." %(address , datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S") )
        except errors.HttpError, error:
            return  'An error occurred: %s' % error

因此，我得到了一个大小为 9.8MB 的特定 .zip 文件的可爱文字墙（我能够通过 gmail 手动发送它）：

我想我的消息格式不正确，但我不知道为什么以及在哪里...

找到问题了！

我有这个：

zf = zipfile.ZipFile(path, mode='w')

然后我安装了zlib，把压缩改成了：

zf = zipfile.ZipFile(path, mode='w', compression=zipfile.ZIP_DEFLATED)

暂时没有...或任何类型的错误。我想 Gmail 在某些情况下只是不喜欢 zipfile 模块的默认压缩。
