抱歉,这是一个基本问题,但是我到处都在寻找通过youtube api调用command-line的用法示例以及如何设置其正确的元数据字段的示例。

以下代码由Google在此处提供:Search Youtube by 'keyword'

#!/usr/bin/python

import os
from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser

DEVELOPER_KEY = "mykey"
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)

  search_response = youtube.search().list(
    q=options.q,
    part="id,snippet",
    maxResults=options.max_results
  ).execute()

  videos = []
  channels = []
  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)
search.py


我遵循了此处给出的示例:Youtube>Data API>SampleRequests

例如,我尝试搜索Karma Police视频,因此:

$ python script.py --q="karma police",无济于事。它什么也不打印。

我想念什么?

ps。在同一目录中的环境.json file中设置了更多凭据。

编辑:追溯:

最佳答案

按照步骤provided in the docs。最后,您需要将GOOGLE_APPLICATION_CREDENTIALS指向您下载的json文件,例如:

export GOOGLE_APPLICATION_CREDENTIALS=~/Downloads/youtube-search-b0e0b347241c.json


当然,最好将文件移到安全的地方,例如进入~/.credentials/chmod 700该目录。
