如何将JSON字符串转换为Python对象（字典）

Question

我有一个奇怪的问题。运行Django 3.0.1，在我看来，我有一条try语句。由于某种原因，我无法将JSON字符串转换为Python对象（字典）。这是我的代码：

        try:
            message_to_clientsservice = {
                'id': id_id,
                'name': 'create-member-client-for-tenant-setup',
                'payload': {
                    'clientName': client_name,
                    'kbCorporationId': int(kb_corp_id),
                    'email': email,
                    'clientTypeId': client_type_id,
                    'address': {
                        'countryCode': country_code,
                    },
                    'phoneNumbers': []
                }
            }

            clientsservice_request_header = {
                'Content-Type': 'application/json',
                'ServiceAccessToken': service_access_token,
                'Ocp-Apim-Subscription-Key': ocp_apim_subscription_key,
                'Authorization': 'Bearer ' + bearer_token
            }

            # print(message_to_clientsservice)
            # print(type(message_to_clientsservice))
            # print(json.dumps(message_to_clientsservice))
            # print(type(clientsservice_request_header))
            # print(clientsservice_request_header)
            clients_service_response = requests.post(clientsservice_url,
                                                     headers=clientsservice_request_header,
                                                     data=json.dumps(message_to_clientsservice))
            print(clients_service_response.status_code)
            json_data_scrambledegg = clients_service_response.text
            for r in (('\\', ''), ('{\\', ''), ('\"\"}\"}', '\"\"}}'), ('\"payload\":\"', '\"payload\":')):
                json_data_scrambledegg = json_data_scrambledegg.replace(*r)
            print(type(json_data_scrambledegg))
            print(json_data_scrambledegg)
            data = json.loads(json_data_scrambledegg)
            print(data)
        except:
            print('Something went wrong! Try again or contact your Sysadmin!')
            messages.warning(request, 'Something went wrong! Try again or contact your Sysadmin!')
            return render(request, 'create_member_company/create_member_feedback.html')
        else:
            messages.success(request, 'Your Message was sent successfully!')
            return render(request, 'create_member_company/create_member_feedback.html')

并获得此输出：

我的“尝试”中的最后2行失败。它们是（来自上面的try语句）。

data = json.loads(json_data_scrambledegg)
print(data)

只需致电response.json()即可获得字典：

try:
    ...
    clients_service_response = requests.post(clientsservice_url,
                                             headers=clientsservice_request_header,
                                             data=json.dumps(message_to_clientsservice))
    print(clients_service_response.status_code)
    data = clients_service_response.json() # this line!!
    print(data)
except:
    ...
else:
    ...

正确的代码

try:
    message_to_clients_service = {
        'id': id_id,
        'name': 'create-member-client-for-tenant-setup',
        'payload': {
            'clientName': client_name,
            'kbCorporationId': int(kb_corp_id),
            'email': email,
            'clientTypeId': client_type_id,
            'address': {
                'countryCode': country_code,
            },
            'phoneNumbers': []
        }
    }

    clients_service_request_header = {
        'Content-Type': 'application/json',
        'ServiceAccessToken': service_access_token,
        'Ocp-Apim-Subscription-Key': ocp_apim_subscription_key,
        'Authorization': 'Bearer ' + bearer_token
    }

    clients_service_response = requests.post(clientsservice_url,
                                             headers=clients_service_request_header,
                                             json=message_to_clients_service)
    print(clients_service_response.status_code)
    data = clients_service_response.json()  # this line!!
    print(data)
except:
    print('Something went wrong! Try again or contact your Sysadmin!')
    messages.warning(request, 'Something went wrong! Try again or contact your Sysadmin!')
    return render(request, 'create_member_company/create_member_feedback.html')
else:
    messages.success(request, 'Your Message was sent successfully!')
    return render(request, 'create_member_company/create_member_feedback.html')
