在twilio + flask + python + whatsapp自动化中出错

问题描述

我正在尝试使用python进行Whatsapp自动化，而烧瓶在Whatsapp中向Twilio发送消息时出现了一些错误。我的代码是这个

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，我还必须在Twilio中更改链接，但仍然会出错。

解决方法

您需要实例化一个响应并在其上调用.message方法。

来自文档的

： 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!")

您收到的错误来自以下事实：一个类的所有方法（包括__init__）都在self中传递，这就是为什么您传递的消息成为第二个参数并且Python抛出该错误的原因TypeError: __init__() takes 1 positional argument but 2 were given错误
