Answer 1

这是我在谷歌官方开发网站上发现的

#!/usr/bin/python
from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser

# Set DEVELOPER_KEY to the API key value from the APIs & auth > Registered apps
# tab of
#   https://cloud.google.com/console
# Please ensure that you have enabled the YouTube Data API for your project.
DEVELOPER_KEY = "REPLACE_ME"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"
def youtube_search(options):
  youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
    developerKey=DEVELOPER_KEY)
  # Call the search.list method to retrieve results matching the specified
  # query term.
  search_response = youtube.search().list(
    q=options.q,
    part="id,snippet",
    maxResults=options.max_results
  ).execute()
  videos = []
  channels = []
  playlists = []
  # Add each result to the appropriate list, and then display the lists of
  # matching videos, channels, and playlists.
  for search_result in search_response.get("items", []):
    if search_result["id"]["kind"] == "youtube#video":
      videos.append("%s (%s)" % (search_result["snippet"]["title"],
                                 search_result["id"]["videoId"]))
    elif search_result["id"]["kind"] == "youtube#channel":
      channels.append("%s (%s)" % (search_result["snippet"]["title"],
                                   search_result["id"]["channelId"]))
    elif search_result["id"]["kind"] == "youtube#playlist":
      playlists.append("%s (%s)" % (search_result["snippet"]["title"],
                                    search_result["id"]["playlistId"]))
  print "Videos:n", "n".join(videos), "n"
  print "Channels:n", "n".join(channels), "n"
  print "Playlists:n", "n".join(playlists), "n"

if __name__ == "__main__":
  argparser.add_argument("--q", help="Search term", default="Google")
  argparser.add_argument("--max-results", help="Max results", default=25)
  args = argparser.parse_args()
  try:
    youtube_search(args)
  except HttpError, e:
    print "An HTTP error %d occurred:n%s" % (e.resp.status, e.content)

1）首先获取搜索结果。搜索结果将不包含点赞和评论计数2） 对于每个搜索结果，激发一个api请求以获取视频信息

下面的代码将为您提供搜索结果中每个视频的点赞数和评论数。

  for search_result in search_response.get("items", []):
    if search_result["id"]["kind"] == "youtube#video":
      payload = {'id': search_result["id"]["videoId"], 'part': 'statistics', 'key': DEVELOPER_KEY}
      l = requests.Session().get('https://www.googleapis.com/youtube/v3/videos', params=payload)    
      resp_dict = json.loads(l.text)
      print "commentCount: ",resp_dict['items'][0]['statistics']['commentCount']
      print "likeCount: ",resp_dict['items'][0]['statistics']['likeCount']
