如何在 python 中为 FB 聊天机器人添加负载请求？

Question

我在python、flask、pymessenger、witai 中创建了一个聊天机器人。我添加了一些按钮，但我不知道如何在用户 press/select 从我的菜单中选择选项后回复。下面是我的代码。

@app.route('/', methods=['GET'])
def verify():
    if request.args.get("hub.mode") == "subscribe" and request.args.get("hub.challenge"):
        if not request.args.get("hub.verify_token") == "hello":
            return "Verification token mismatch", 403
        return request.args["hub.challenge"], 200
    return "Hello World", 200

@app.route('/', methods=['POST'])
def webhook():
    data = request.get_json()
    log(data)

    if data['object'] == 'page':
        for entry in data['entry']:
            for messaging_event in entry['messaging']:

                sender_id = messaging_event['sender']['id']
                recipient_id = messaging_event['recipient']['id']

                if messaging_event.get('message'):
                    if 'text' in messaging_event['message']:
                        messaging_text = messaging_event['message']['text']
                    else:
                        messaging_text = 'no text'

                    response = None

                    entity, value = wit_response(messaging_text)

                    if entity == 'cust_id':
                        test = cust(str(value))
                        buttons = []
                        button = Button(title='1. Pizza', type='postback', payload='Pizza')
                        buttons.append(button)
                        button = Button(title='2. Burger', type='postback', payload='Burger')
                        buttons.append(button)
                        button = Button(title='3. Pasta', type='postback', payload='Pasta')
                        buttons.append(button)
                        text = 'Hey '+test[0] +'.'+"\n"+'Select Option:'
                        bot.send_button_message(sender_id, text, buttons)

我不知道用户选择一个选项后如何处理请求。例如，如果用户选择比萨，我想 return 文本或按钮格式的比萨菜单。

您可以从 data

中检索负载

if 'postback' in data['entry'][0]['messaging'][0] :  
    payload = data['entry'][0]['messaging'][0]['postback']['payload']
    sender = data['entry'][0]['messaging'][0]['sender']['id']
