def start(url='https://github.com/pawansankhle/my-iot/raw/master/dev/'+ _config.get_client_id() +'/update.json'):
    try:
        import ujson as json
        print(url)
        res = http_get(url)
        print(res)
        response = json.loads(res)
        print(response)
        for file in response['files']:
            path = file['path']
            url = 'https://raw.githubusercontent.com/pawansankhle/my-iot/master/dev/{}'.format(path)
            http_get_to_file(url, path)
    except Exception as ex:
            print(ex)

и это мой метод http_get, чтобы получить реальные данные

def http_get(url): response = b'' try: get = http_get_async(url), в то время как True: file_bytes = get.send(None) ответ += file_bytes, кроме StopIteration: pass

response_str = str(response, 'utf-8')
return response_str
