Скрипт для скачивания музыки с сайта vkontakte.ru (vk.com) | |
Запуск: | |
python vkcom_audio_download.py | |
Принцип работы: | |
Скрипт проверяет сохраненный access_token. Если его нет или срок истек, | |
то открывается страница в браузере с запросом на доступ к аккаунту. | |
После подтверждения идет редирект на https://oauth.vk.com/blank.htm#... . | |
Нужно скопировать весь url, на который вас редиректнуло и вставить его | |
в консоль скрипта. | |
Далее будут скачиваться все ваши аудиозаписи. Если аудиозапись уже есть на | |
диске - то скачивания не происходит. | |
Будут запрошены ваши данные приложением с app_id = 3358129 | |
Можно создать свое Standalone-приложение с доступом к аудио здесь: | |
http://vk.com/editapp?act=create | |
И заменить APP_ID на ваше. | |
