如何获得来自 twilio 的呼叫的 JSON API 响应？

Question

我无法获取 JSON 响应，如 tutorial 中所示。

我已经实现了一个可编程语音程序。我想向用户显示通话的详细信息，如果我得到 JSON 响应，我将能够获得所有这些（费用、持续时间、状态等）。

# views.py
def start_campaign(request, campaign_id):

    try:
        campaign = Campaign.objects.get(pk=campaign_id)
        account_sid = 'XXX'
        auth_token = 'XXX'
        client = Client(account_sid, auth_token)

        phone_numbers = Contact.objects.filter(phone_book=campaign.phone_book)
        custom_url = 'http://XXX.ngrok.io/assets/' + str(campaign_id)

        for phone_number in phone_numbers:

            call = client.calls.create(
                method='GET',
                status_callback='http://XXX.ngrok.io/events',
                status_callback_event='completed',
                status_callback_method='GET',
                url=str(custom_url),
                to=str(phone_number),
                from_='+1XXX'
            )
            detail = client.calls(str(call.sid)).fetch()
            print(detail.price)

    except Campaign.DoesNotExist:
        raise Http404("Campaign Does Not Exist")

    context = {
        'all_campaigns': campaign
    }

    return render(request, "CallCenter/start_campaign.html", context)


def events(request):
    status = request.GET.getlist('CallStatus', default=None)
    duration = request.GET.getlist('CallDuration', default=None)

    print("Duration:{}\nStatus:{}".format(duration, status))

    return render(request, "CallCenter/events.html")

在终端中，我得到一个输出，打印出来自

的呼叫的状态和持续时间

"GET /events?Called=%2BXX&ToState=&CallerCountry=US&Direction=outbound-api&Timestamp=Sat,+12+Oct+2019+19:11:50+%2B0000&CallbackSource=call-progress-事件&SipResponseCode=200&Ca llerState=AL&ToZip=&SequenceNumber=0&CallSid=XXX&To=%2BXXX&CallerZip=35766&ToCountry=IN&CalledZip=&ApiVersion=2010-04-01&CalledCity=&CallStatus=completed&Duration=1&From= %2BXXX&CallDuration=5&AccountSid=XXX&CalledCountry=IN&CallerCity=ESTILLFORK&ToCity=&FromCountry=US&Caller=%2B12563804721&FromCity=ESTILLFORK&CalledState=&FromZip=35766&Fro mState=AL HTTP/1.1" 200 123

打印出来

持续时间：['5', '5']

状态：['completed'、'completed']

不幸的是，我不知道如何请求 Twilio 的 JSON 回复。

收到回调后，您在 GET 数据中就有了 CallSid ID。所以你可以用它来获取完整的 Call 资源：

def events(request):
    sid = request.GET['CallSid']
    call = client.calls(sid).fetch()
    print(call.price)
