如何在pymessenger上向FB Messenger发送“ typing_on”帖子？

问题描述

我正在尝试将聊天机器人设置为在向用户发送响应之前显示气泡，以使其更人性化。我遵循了文档，但是仍然从机器人那里获得了即时响应，没有键入气泡。根据{{​​3}}，我正在使用此发送者操作：

{"recipient":{"id":recipient_id},"sender_action":"typing_on"}

并把它放在上下文中，这是我在烧瓶应用程序中使用它的方式：

@app.route('/',methods=['GET','POST'])
def receive_message():
    global tag,latest_message
    if request.method == 'GET':
        # Before allowing people to message your bot Facebook has implemented a verify token
        # that confirms all requests that your bot receives came from Facebook.
        token_sent = request.args.get("hub.verify_token")
        return verify_fb_token(token_sent)
    # If the request was not GET,it  must be POSTand we can just proceed with sending a message
    # back to user
    else:
            # get whatever message a user sent the bot
        output = request.get_json()
        for event in output['entry']:
            messaging = event['messaging']
            for message in messaging:
                if message.get('message'):
                    # Facebook Messenger ID for user so we kNow where to send response back to
                    recipient_id = message['sender']['id']
                    if message['message'].get('text'):
                        response_sent_text = send(message['message'].get('text'))
                        send_message(recipient_id,response_sent_text)
                        latest_message = response_sent_text
    return "Message Processed"

def send_message(recipient_id,response):
    # sends user the text message provided via input response parameter
    typing_payload = {"recipient":{"id":recipient_id},"sender_action":"typing_on"}
    bot.send_raw(typing_payload)
    print(bot.send_raw(typing_payload))
    bot.send_text_message(recipient_id,response)
    return "success"

任何想法将不胜感激！

解决方法

您应该传递有效负载的字符串表示形式（而不是字典）。

尝试执行以下操作：

import json

...


def send_message(recipient_id,response):
    # sends user the text message provided via input response parameter
    typing_payload = json.dumps({"recipient":{"id":recipient_id},"sender_action":"typing_on"})
    bot.send_raw(typing_payload)
    print(bot.send_raw(typing_payload))
    bot.send_text_message(recipient_id,response)
    return "success"

与直接发送消息之前相反，最好的做法是在接收消息时发送这些指示符（在处理时显示打字指示符）。
