JsonResponse序列化

Question

正在处理一个项目，当我引入API部分时，我收到此错误“不是JSON可序列化的”

我的tasks.py文件看起来像这样

@shared_task
def balanceQueryTask(payload):
    #rData = JSONParser().parse(payload)
    url = 'some url'
    data = {'organizationID':payload['organizationID'], 'orderID':payload['orderID'], 'operation':payload['operation']}
    headers = {'Content-Type':'application/json'}
    response = requests.post(url, data=json.dumps(data), headers=headers) #convert from dict to json "json.dumps()"
    responseObj = response.json()
    availableBalance = str(int(responseObj['balance']['availableBalance'])/100)

    if response.status_code == 200:
        return JsonResponse({'response_code':responseObj['response_code'], 
            'response_status':responseObj['response_status'], 
            'availableBalance':availableBalance
            })
    else:
        return JsonResponse({'response_code':'E2', 'response_status':'Failed'})
