Twilio CallBackStatus和烧瓶

如何解决Twilio CallBackStatus和烧瓶

我正在尝试触发呼叫并获取该呼叫的实时状态更新。我可以通过访问网站来触发呼叫，但是在弄清楚如何通过CallBackStatus发出的呼叫上实时接收更新时遇到了问题。设置Call​​BackStatus URL时-twilio应该提供有关呼叫状态的实时更新，包括启动，响铃，应答和完成。我在ngrok转发网址中输入“ / events”，以为信息将发送到该网址，但我看不到。如何在我的flask＆ngrok应用程序中从Twilio获取实时呼叫状态更新？

from flask import Flask,request
from twilio.twiml.voice_response import VoiceResponse
from twilio.rest import Client
import time

app = Flask(__name__)

client = Client("ENTER ACCOUNT SID","ENTER ACCOUNT TOKEN")

NGROK_BASE_URL = 'ENTER NGROJK FORWARDING URL HERE'
from_="ENTER TWILIO NUMBER HERE"  # twilio number
to = 'ENTER NUMBER TO CALL HERE'  # number to call


@app.route('/')
def index():
    """Returns standard text response to show app is working."""
    return "Twilio Flask app up and running!"


@app.route('/twiml',methods=['GET','POST'])
def twiml_response():
    """Provides TwiML instructions in response to a Twilio POST webhook
    event so that Twilio knows how to handle the outbound phone call
    when someone picks up the phone.
    """
    response = VoiceResponse()
    response.say('hello Daman!!!!')
    return str(response)


@app.route('/dial-phone',methods=['GET'])
def outbound_call():
    """Uses the Twilio Python helper library to send a POST request to
    Twilio telling it to dial an outbound phone call from our
    specific Twilio phone number (that phone number must be owned by our
    Twilio account).
    """
    # the url must match the Ngrok Forwarding URL plus the route defined in
    # the previous function that responds with TwiML instructions
    client.calls.create(method='Post',to=to,from_=from_,url=NGROK_BASE_URL + '/events',status_callback_event='initiated ringing answered completed',status_callback=NGROK_BASE_URL + '/events',status_callback_method='POST',)
    return 'phone call placed to ' + to + '!'

# TODO find out how to get callback events - NOT WORKING


@app.route('/events','POST'])
def twiml_response():
    all_call_info = request.values
    print(all_call_info)
    call_status = request.values.get('CallStatus','')
    print(call_status)
    time.sleep(5)
    print(call_status)
    time.sleep(5)
    print(call_status)
    time.sleep(5)
    return call_status


if __name__ == '__main__':
    app.run()
