JSON请求响应类型错误 - Django

Question

我有一个Json请求，我正在发送django项目。我发送请求，我得到的回应正如我所期待的那样。但我认为响应会以字符串形式返回，而不是文件或可迭代文件。我不确定如何确保响应是正确的格式来处理。这是我从django views.py文件发送的请求......

def createUserSynapse(request):
    data = {
        "logins":[
            {
                "email":"test@test.com",
            }
        ],
        "phone_numbers":[
            "123.456.7890",
            "test@test.com",
        ],
        "legal_names":[
            "Test name",
        ],
        "extras":{
            "supp_id":"asdfe515641e56wg",
            "cip_tag":12,
            "is_business":False,
        }
    }

    req = urllib.request.Request('http://uat-api.synapsefi.com')
    req.add_header('X-SP-GATEWAY', 'client_id_asdfeavea561va9685e1gre5ara|client_secret_4651av5sa1edgvawegv1a6we1v5a6s51gv')
    req.add_header('X-SP-USER-IP', '127.0.0.1')
    req.add_header('X-SP-USER', '| ge85a41v8e16v1a618gea164g65')
    req.add_header('Content-Type', 'application/json')

    print(req.headers)

    response = urllib.request.urlopen(req, json.dumps(data).encode('utf8'))

    print(response)

    return render(reqest, 'tabs/create_user_synapse.html', response)

另外，第二次到最后一次应该打印响应并且它不打印任何东西......

任何人都可以帮助我...... 这是完整的错误：
