Преобразование JSON в URL текст

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_entities][contacts][0][name]=John &add[0][incoming_entities][contacts][0][responsible_user_id]=2473552 &add[0][incoming_entities][contacts][0][custom_fields][0][id]=382707 &add[0][incoming_entities][contacts][0][custom_fields][0][values][0][value]=+792887776655 &add[0][incoming_entities][contacts][0][custom_fields][0][values][0][enum]=MOB &add[0][incoming_entities][contacts][0][custom_fields][1][id]=389993 &add[0][incoming_entities][contacts][0][custom_fields][1][values][0][value]=cid123456789 &add[0][incoming_entities][contacts][0][custom_fields][2][id]=389995 &add[0][incoming_entities][contacts][0][custom_fields][2][values][0][value]=Product &add[0][incoming_lead_info][form_id]=329248 &add[0][incoming_lead_info][form_page]=localhost &add[0][incoming_lead_info][ip]=127.0.0.1 &add[0][incoming_lead_info][service_code]=myformmw
Это декодированные данные из URL text, которые принимает API:
add%5B0%5D%5Bsource_name%5D=WEB+FORM&add%5B0%5D%5Bsource_uid%5D=wb0123456789&add%5B0%5D%5Bcreated_at%5D=1529105760&add%5B0%5D%5Bincoming_entities%5D%5Bleads%5D%5B0%5D%5Bname%5D=WEB+Bay&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bname%5D=John&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bresponsible_user_id%5D=2473552&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B0%5D%5Bid%5D=382707&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B0%5D%5Bvalues%5D%5B0%5D%5Bvalue%5D=%2B792887776655&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B0%5D%5Bvalues%5D%5B0%5D%5Benum%5D=MOB&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B1%5D%5Bid%5D=389993&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B1%5D%5Bvalues%5D%5B0%5D%5Bvalue%5D=cid123456789&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B2%5D%5Bid%5D=389995&add%5B0%5D%5Bincoming_entities%5D%5Bcontacts%5D%5B0%5D%5Bcustom_fields%5D%5B2%5D%5Bvalues%5D%5B0%5D%5Bvalue%5D=Product&add%5B0%5D%5Bincoming_lead_info%5D%5Bform_id%5D=329248&add%5B0%5D%5Bincoming_lead_info%5D%5Bform_page%5D=localhost&add%5B0%5D%5Bincoming_lead_info%5D%5Bip%5D=127.0.0.1&add%5B0%5D%5Bincoming_lead_info%5D%5Bservice_code%5D=myformmw
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.

Ответ

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:
