어떻게 지구에 당신이 UI 수준에서 그렇게 하시겠습니까? [Youtube API] (https://developers.google.com/youtube/getting_started)를 사용할 수없는 이유가 있나요? –
@ https://code.google.com/p/selenium/wiki/GettingStarted 코드와 비슷한 것을하려고합니다. 작동하지만 YouTube 추천은 작동하지 않습니다. 이것은 웹 드라이버를 사용하는 자동화를위한 것입니다. – kasukur
YouTube 또는 Google 기반 사이트 일 수도 있지만 사이트 자동화에 사용하기가 끔찍합니다. 나는 당신이하려고하는 모든 것이 * 뭔가 *를 사용하는 것이라면 뭔가 다른 것을 시도 할 것입니다. – Arran
