Question

我是python开发人员，并且正在使用python开发Facebook机器人。它运行良好，没有出现以下问题：

class FacebookBotViewSet(generic.View):
def get(self, request, *args, **kwargs):
    if self.request.GET['hub.verify_token'] == settings.FACEBOOK_VERIFY_TOKEN:
        return HttpResponse(self.request.GET['hub.challenge'])
    else:
        return HttpResponse('Error, invalid token')

# Post function to handle Facebook messages
def post(self, request, *args, **kwargs):
    from ai_api.services.widget import WidgetService
    fb_request_object = FBRequestObject(self.request.body)
    fb_messenger_objects = fb_request_object.get_messenger_objects()
    for fb_messenger_object in fb_messenger_objects:
        fb_page_id = fb_messenger_object.get_page_id()
        msg_text = fb_messenger_object.get_text()
        msg_mid = fb_messenger_object.get_mid()
        sender_id = fb_messenger_object.get_sender_id()
        is_get_started = fb_messenger_object.is_post_back() and msg_text == FacebookPostBack.GET_STARTED
        if sender_id and ((msg_text and msg_mid) or is_get_started):
            widget = WidgetService.get_by_fb_page_id(fb_page_id)
            if widget:
                fb_page_token = widget.fb_access_token
                FacebookService.post_facebook_message(fb_page_token, sender_id, '')
                is_continue = True
                if is_get_started:
                    try:
                        msg_text = FacebookService.get_fb_name(sender_id, fb_page_token)
                    except Exception as e:
                        is_continue = False
                        reply_text = e.error.get('message')
                        FacebookService.post_facebook_message(fb_page_token, sender_id, reply_text)

                if is_continue:
                    webhook_callback = PBLWebhookViewSet.as_view({'post': 'callback'})
                    kwargs = {
                        "sender_id": sender_id,
                        "text": msg_text,
                        "page_id": fb_page_id,
                        "web_id": widget.id,
                        "mid": msg_mid,
                        "is_get_started": is_get_started,
                        "source": ApplySource.FACEBOOK_MESSAGER
                    }
                    response = webhook_callback(self.request, **kwargs)
                    if response and response.data:
                        reply_text = response.data.get('body', '')
                        kb_message = response.data.get('kb_message', '')
                        sender_id = fb_messenger_object.get_sender_id()
                        if reply_text:
                            FacebookService.reply_facebook_message(fb_page_token, sender_id, reply_text)
                        if kb_message:
                            FacebookService.reply_facebook_message(fb_page_token, sender_id, kb_message)

    return HttpResponse()

您可以看到post方法，每当Facebook用户向我的页面发送消息时，该方法就会被调用。但是，当获取响应消息的处理花费太多时间（约10秒）时，就会一次又一次调用post方法。我的意思是，当我的页面收到新消息时，该方法将被调用多次。这是错误的。任何人都可以向我展示如何防止该问题，然后仅对每条消息调用一次回发方法。谢谢
