Преобразование JSON в URL текст

#python #json #post #api #urlencode

В поисках решения вот этой проблемы выяснил, что проблема в API, оно принимает не
JSON, а в отправляемых данных должен быть URL text. Вопрос такой, можно ли преобразовать
такой JSON:

JSONFORMDATA = {

"add": [
{
    "source_name": "WEB сайт",
    "source_uid": "a1fee7c0fc436088e64ba2e8822ba2b3",
    "created_at": "1529007000",
    "incoming_entities": {
        "leads": [
            {
                "name": "Покупка"
            }
        ],
        "contacts": [
            {
                "name": "Федя",
                "responsible_user_id": "1903006",
                "custom_fields": [
                    {
                        "id": "382707",
                        "values": [
                            {
                                "value": "+77777777777",
                                "enum": "WORK"
                            }
                        ]
                    },
                    {
                        "id": "389993",
                        "values": [
                            {
                                "value": "sfgh3gh233h3h3h3"
                            }
                        ]
                    },
                    {
                        "id": "389995",
                        "values": [
                            {
                                "value": "Обратный звонок"
                            }
                        ]
                    }
                ]
            }
        ]
    },
    "incoming_lead_info": {
        "form_id": "329248",
        "form_page": "vdtest.ru",
        "ip": "127.0.0.1",
        "service_code": "QkKwSam8"
    }
}
]

}


в такой формат:

add[0][source_name]=WEB FORM
&add[0][source_uid]=wb0123456789
&add[0][created_at]=1529105760
&add[0][incoming_entities][leads][0][name]=WEB Bay

&add[0][incoming_lead_info][service_code]=myformmw


Это декодированные данные из URL text, которые принимает API:

Как выяснилось, в примере PHP не используют чистый JSON, а строят массив. Может в
Python тоже необходимо построить подобный массив или есть способ проще, ведь на сколько
я понимаю, как таковых массивов в Python нет.

Честно, рекурсию не очень люблю, но в таких задачах она себя хорошо показывает:

Данные (из вопроса):

JSON_FORM_DATA = {
    "add": [
        ...
}


Код:

def dict_to_url_params(json_data, root):
    def deep(node, root, items):
        if isinstance(node, list):
            for i, value in enumerate(node):
                node_root = root + '[{}]'.format(i)
                deep(value, node_root, items)

        elif isinstance(node, dict):
            for key, value in node.items():
                node_root = root + '[{}]'.format(key)
                deep(value, node_root, items)

        else:
            root += '=' + node
            items.append(root)

    items = []

    deep(json_data, root, items)

    return items


if __name__ == '__main__':
    items = dict_to_url_params(JSON_FORM_DATA['add'], root='add')

    params = '&'.join(items)
    print('Params: ' + params)
    print()

    print('Params:')
    for x in items:
        print(x)


Результат:
