YouTube 채널에서 가장 최근에 업로드 한 비디오의 ID를 얻는 방법

Question

Python을 사용하여 특정 YouTube 채널에서 최근 업로드 한 동영상의 ID를 얻으려면 어떻게해야합니까?

Answer 1

JSON을 요청하고 구문 분석 할 수 있습니다. 다음 코드는 첫 번째 (가장 최근) 결과를 제공하고 first에 저장합니다.

import urllib, json 

author = 'Google' 
inp = urllib.urlopen(r'http://gdata.youtube.com/feeds/api/videos?max-results=1&alt=json&orderby=published&author=' + author) 
resp = json.load(inp) 
inp.close() 

first = resp['feed']['entry'][0] 

# Title of the video 
print first['title'] 

# URL 
print first['link'][0]['href'] 

대화식 Python 쉘에서 JSON 객체를 살펴 보았습니다. build your own query 또는 내가 게시 한 것을 사용할 수 있습니다. 저자를 변경하는 것을 잊지 마십시오. 이것은 낮은 수준의 접근이며, @ Frederik은 다소 높은 수준을 언급했습니다.

first 개체는 다음과 같습니다.
