在 twilio + flask + python + whatsapp 自動化中出錯

Question

我正在嘗試使用 python 和燒瓶進行 Whatsapp 自動化，當我在 Whatsapp 中向 Twilio 發送消息時遇到一些錯誤。 我的代碼是這樣的

from flask import Flask,request
from twilio.twiml.messaging_response import MessagingResponse
import io
import datetime
#import xmlrpc.client import strftime

appbot=Flask(__name__)
@appbot.route("/sms",methods=["get","post"])

def reply():
    with io.open("response.csv","a",encoding="utf-8")as f1:
        ur = request.form.get("Body")
        un = request.form.get("From")
        print(un)
        print(ur)
        un = un.replace("whatsapp:","")
        dt=datetime.datetime.now().strftime("%y%m%d--%H%M%S")
        data = un+","+ur+","+dt
        f1.write(data)
        resp = MessagingResponse("You sent"+" "+ur+"from"+" "+un+"on"+" "+dt)
        return(str(resp))
    
    f1.close()
    
    
if (__name__ == "__main__"):
    appbot.run()

首先，我還必須更改 Twilio 中的鏈接，但我仍然遇到錯誤。

您需要實例化一個響應並在其上調用.message方法。

來自文檔： https : //www.twilio.com/docs/sms/tutorials/how-to-receive-and-reply-python

@app.route("/sms", methods=['GET', 'POST'])
def sms_reply():
    """Respond to incoming calls with a simple text message."""
    # Start our TwiML response
    resp = MessagingResponse()

    # Add a message
    resp.message("The Robots are coming! Head for the hills!")

你得到的錯誤來自一個類的所有方法（包括__init__ ）都傳入self ，這就是為什么你傳入的消息成為第二個參數並且 Python 拋出TypeError: __init__() takes 1 positional argument but 2 were given錯誤
