python - Youtube API returning 1 video per request or errors

问题描述

I created code to extract data from Youtube API search query:

from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser
from oauth2client import client, GOOGLE_TOKEN_URI
import json

DEVELOPER_KEY = "my key"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"

def youtube_search(q, max_results=50,order="relevance", token=None, location=None, location_radius=None):

    youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)

    search_response = youtube.search().list(q=q, type="video", pageToken=token, order = order, part="id,snippet", maxResults=max_results, location=location, locationRadius=location_radius).execute()

    videos = []

    for search_result in search_response.get("items", []):
        if search_result["id"]["kind"] == "youtube#video":
            videos.append(search_result)
            try:
                nexttok = search_response["nextPageToken"]
                return(nexttok, videos)
            except Exception as e:
                nexttok = "last_page"
                return(nexttok, videos)

when I test the function with the search query, 

youtube_search('sport')

sometimes return a timeout error:

timeout: The read operation timed out

sometimes return ConnectionResetError error:

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

and sometimes it return only one video per token:

('CDIQAA',
 [{'kind': 'youtube#searchResult',
   'etag': '"Fznwjl6JEQdo1MGvHOGaz_YanRU/ig3kkPiIvrPIiptur1Y1wpzbSlU"',
   'id': {'kind': 'youtube#video', 'videoId': '3TJP5a3pBME'},
   'snippet': {'publishedAt': '2018-07-29T16:00:52.000Z',
    'channelId': 'UCBINFWq52ShSgUFEoynfSwg',
    'title': '20-Minute Victoria Sport Workout For Toned Abs and Legs',
    'description': "Stay strong all Summer with Victoria Sport Ambassador Lindsey Harrod's 20-minute high-impact cardio workout. Tone your whole body through circuits including ...",
    'thumbnails': {'default': {'url': 'https://i.ytimg.com/vi/3TJP5a3pBME/default.jpg',
      'width': 120,
      'height': 90},
     'medium': {'url': 'https://i.ytimg.com/vi/3TJP5a3pBME/mqdefault.jpg',
      'width': 320,
      'height': 180},
     'high': {'url': 'https://i.ytimg.com/vi/3TJP5a3pBME/hqdefault.jpg',
      'width': 480,
      'height': 360}},
    'channelTitle': 'POPSUGAR Fitness',
    'liveBroadcastContent': 'none'}}])

I need the function to return 50 videos per request but the function is unstable (errors) or refuse to return 50 videos.

解决方案

我有同样的错误，我认为它是由 http 请求没有更新引起的，我通过每次调用请求的函数时构建发现资源来解决它，它对我有用。

from googleapiclient.discovery import build
import time


def url_sinffer(search_word):
    api_key = "Your Api key"
    youtube = build('youtube', 'v3', developerKey=api_key)
    print(type(youtube))
    request = youtube.search().list(
        part="id",
        q=search_word,
        maxResults=1,
        type="music"
    )
    response = request.execute()
    time.sleep(0.5)

    video_id = response['items'][0]['id']['videoId']
    url = f'https://www.youtube.com/watch?v={video_id}'
    return url
