ユーザーの入力を無限に繰り返すフェイスブックボットを作成する方法。ユーザーが特定のコマンド（たとえば、bye）を入力した場合にのみ停止します。

Question

私は単にユーザー入力をエコーするfbボットを作成しました。 ユーザー入力を続けてエコーし、ユーザーが "bye"を入力すると停止します。 どうすればいいですか？助けてください。 コード：send_message(sender_id, reply)機能なしの復帰についてどう `` `輸入OS 輸入SYS 輸入JSON

import requests 
import time 
from flask import Flask, request 

app = Flask(__name__) 

@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") == os.environ["VERIFY_TOKEN"]: 
      return "Verification token mismatch", 403 
     return request.args["hub.challenge"], 200 

    return "Hello world", 200 


@app.route('/', methods=['POST'])

    data = request.get_json() 
    if data["object"] == "page":

        message_text = messaging_event["message"]["text"] 

        reply = "Received : " + message_text 

        if "bye" in message_text.lower(): 
         reply = "Good-bye"

Answer 1

？この

if "bye" in message_text.lower(): 
    return "bye", 200

のようにこのコードは、私は彼/彼女が言う後にループは、ファイルやDB内のユーザーのFBIDを追加解除するには、クラスベースのビュー

を使用しているという事実を除いて、あなたに非常によく似ていますさよなら メッセージが投稿される度に、fbidをチェックして、ユーザーがすでに「bye」と言っていたかどうかを確認します。はいの場合は空の応答を返す
