我正在尝试从 youtube 播放列表中获取视频并将其存储到 python 列表中。我按照文档中的说明进行操作 https://developers.google.com/youtube/v3/docs/playlistItems/list但它似乎无法检索视频 ID。

def list_playlist_localizations(youtube, playlist_id):
results = youtube.playlists().list(
part='snippet, contentDetails', id=playlist_id, maxResults=5
).execute()
#print results
for playlist_item in results['items']:
title = playlist_item['snippet']['title']
video_id = playlist_item['snippet']['resourceId']['videoId']
print video_id

编辑:

from hyper import HTTPConnection
import random
import requests

playlist_id = "PLx0sYbCqOb8TBPRdmBHs5Iftvv9TPboYG"
links = []
token = '' # to get ID to next page CDIQAA

# https://stackoverflow.com/questions/14173428/how-to-change-page-results-with-youtube-data-api-v3 - reference

s = requests.Session()
r = s.get('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&playlistId=' + playlist_id + '&key={MY_KEY}')
data = r.json()

while 'nextPageToken' in data and len(data) < 200:
token = data['nextPageToken']

r = s.get('https://www.googleapis.com/youtube/v3/playlistItems?pageToken='
+ token +
'&part=snippet&maxResults=50&playlistId='
+ playlist_id +
'&key=AIzaSyAglPb2-eVaoy1muXclkUrfPFtdYEaUcCw')
data = r.json()
for items in data['items']:
links.append('https://www.youtube.com/watch?v=' + items['snippet']['resourceId']['videoId'])

r = s.get('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&playlistId=' + playlist_id + '&key={MY_KEY}')
data = r.json()

# Add the remaining links
for items in data['items']:
links.append('https://www.youtube.com/watch?v=' + items['snippet']['resourceId']['videoId'])

'''
for items in links:
print items
'''
print "num items: " + str(len(links))

print "Random link: "

print links[random.randint(0, len(links) - 1)]

这是我从播放列表生成随机 YouTube 链接的实现

最佳答案

可以使用html请求获取数据
您将获得作为 JSON 数据的播放列表
例如

import requests,json
key = 'YOUR API KEY'
playlistid = 'PLBCF2DAC6FFB574DE'
data = json.loads(requests.get('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId={}&key={}'.format(playlistid,key)).text)
print(data)

结果会是
