Twilio和Python不工作的对话聊天机器人

Question

我想教我的女朋友如何建立聊天机器人

我们学习了codeacademy课程，学习基于规则的聊天机器人的基础知识，并试图将其集成到Twilio中（在Facebook messenger出现问题后）

from flask import Flask, request
from twilio.twiml.messaging_response import MessagingResponse




app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello, World!"

@app.route("/sms", methods=['POST'])
def sms_reply():
    """Respond to incoming calls with a simple text message."""
    # Fetch the message
    msg = request.form.get('Body')

    # Create reply
    if msg == "bunny" or "michael":

        resp = MessagingResponse()
        resp.message("You said: {}".format(msg))

        return str(resp)


if __name__ == "__main__":
    app.run(debug=True)

在Twilio中使用这段代码可以很好地通过WhatsApp解析上述简单的内容

然而，将其集成到这个聊天机器人中是令人困惑的。如何使用twilio发送和接收消息以使下面的代码正常工作？我有过一场闹剧，但没能成功

import re
import random

class BunnyBot:
  # potential negative responses
  negative_responses = ("no", "nope", "nah", "naw", "not a chance", "sorry")
  # keywords for exiting the conversation
  exit_commands = ("quit", "pause", "exit", "goodbye", "bye", "later", "goodbye", "got to go")
  # random starter questions
  random_questions = (
        "How's your day going Mummy Bunny? ",
        "What do you do when you leave the house? ",
        "What did you have to eat today? I had some fresh weeds. ",
        "Are there other bunnies like me? ",
        "Do you want to come hang out with me in the garden? ",
        "Would you like to help me dig a hole? ",
        "Do you have any carrots today? "
    )

  def __init__(self):
    self.bunnybabble = {'hows_your_day_intent': '.*\s*your day.*','carrots_intent': '.\s*carrot.*', 'cubed_intent': '.*.*(\d+)'}

  # Define .greet() below:
  def greet(self):
    self.name = input("Hi there. Who I am talking to?")
    will_chat = input(f"Hey {self.name}! Do you want to chat with me? ")

        return True

  # Define .chat() next:
  def chat(self):
    reply = input(random.choice(self.random_questions)).lower()
    while not self.make_exit(reply):
      reply = input(self.match_reply(reply))

  # Define .match_reply() below:
  def match_reply(self, reply):
    found = False
    for intent, regPattern in self.bunnybabble.items():
      found_match = re.findall(regPattern, reply)
      if found_match and intent == 'hows_your_day_intent':
        return self.hows_your_day_intent()
      elif found_match and intent == 'carrots_intent':
        return self.carrots_intent()

  def hows_your_day_intent(self):
    responses = ("Pretty relaxing, I've just been napping. ", "Great! I dug a tunnel, do you want to see? ", "Good, but I'm kind of hungry, do you have any snacks? ", "It's been alright, but I'm a bit lonely and would love a pat. ", "So good, just been eating some curtains! ")
    return random.choice(responses)

  def carrots_intent(self):
    responses = ("I love carrots! Can I have one now? ", "Unfortunately I never get a full carrots, only the peel. ", "Carrots are good but so is apple! Do you have a snack for me? ")
    return random.choice(responses)

  def cubed_intent(self, number):
    number = int(number)
    cubed_number = number * number * number
    return (f"The cube of {number} is {cubed_number}. Who knew bunnies were good at maths? ")

  def plans_for_today_intent(self):
    responses = ("I might see if my pigeon friends are around! ", "Maybe hang out with Mummy Bunny if she's doing some gardening. ", "Probably watch some TV with Mummy Bunny and Nicole. ", "I'm just going to hang around until some weeds appear for me to eat. ")
    return random.choice(responses)

  def love_me_intent(self):
    responses = ("Of course I do, you're the best Mummy Bunny ever! ", "I love you so much, no one else gets me weeds like you do. ", "Yes I do, you give the best pats and jaw rubs. ", "Absolutely, thanks for always looking after me. ")
    return random.choice(responses)

  def my_name_intent(self):
    responses = ("Honestly, I'm not sure. It's either Bunny, Fluffy Bun or Heather. It's a bit confusing. ", "Well, someone once mentioned Flat Bunny which got me a little worried. ", "Mummy Bunny calls me Bunny Bun a lot? ")
    return random.choice(responses)

  def favourite_intent(self):
    responses = ("Mummy Bunny obviously. She looks after me. ", "Nicole is pretty cool, after all, I am technically her rabbit. She can be pretty loud though. ", "Natalie is nice to me, but I never really see her anymore which is sad. ")
    return random.choice(responses)

  def no_match_intent(self):
    responses = ("Please tell me more. ", "Tell me more! ", "Why do you say that? ", "I see. Can you elaborate? ", "Interesting. Can you tell me more? ", "I see. How do you think? ", "Why? ", "How do you think I feel when you say that? ")
    return random.choice(responses)


my_bot = BunnyBot()
my_bot.greet()

我认为这与利用TwTwillio消息响应有关，但我不明白它是如何记住过去说过的话的

更新

这是新代码，基于此youtube教程，尝试与Twilio一起使用：

正在尝试使用Ngrok，但尚未正常工作-有任何线索吗

Answer 1

你就快到了

TL；博士

你的机器人在命令行上运行良好。 唯一的问题是把它挂在twilio上

逐步解决

1. 使用twilio代码创建两个函数。发送和接收功能 i、 e

def send(msg):
        resp = MessagingResponse()
        resp.message(format(msg))
        return str(resp)

def recv():
        return request.form.get('Body')

1. 测试这些函数，并根据需要进行修改。因为我没有帐户所以没有测试
2. 将打印更改为send，将输入更改为send和recv i、 e

输入

msg = input("Hi there. Who I am talking to?")
# change it to
send("Hi there. Who I am talking to?")
msg = recv()

打印

print ("No worries, see you later!")
#change this to
send("No worries, see you later!")

这样，您将有一个工作聊天机器人

为什么要使用发送和接收功能

它将帮助您将bot扩展或移植到其他平台，如 电报、推特或其他提供商，如gupshup.io
