逐页获取 YouTube 频道中的所有视频

Question

我需要从 YouTube 频道逐页获取所有视频。 YouTube API 允许一个人最多获得 50 个视频。 现在，我只得到 25 个视频并在页面中打印，使用 Django 分页。如何在页面上打印 YouTube 上的所有视频？

views.py 用于视频视图：

YOUTUBE_VIDEO_URL = "https://gdata.youtube.com/feeds/api/videos?author=*****&orderby=updated&v=2&alt=jsonc"

class VideoListView(ListView):
    template_name = "video/list.html"
    context_object_name = 'videos'
    paginate_by = 12
    def get_queryset(self, **kwargs):
        request = requests.get(settings.YOUTUBE_VIDEO_URL)
        data_about = simplejson.loads(request.text)
        video_list = []
        for item in data_about['data']['items']:
            video_list.append(item)
        return video_list

查看：

    <div id="list_articles">
                {% if videos %}
                    {% for video in videos %}
                        <div class="article">
                            <iframe src="http://www.youtube.com/embed/{{ video.id }}"
                                    width="300" height="225" frameborder="0" allowfullscreen></iframe>
                            <h2><a class="popup-youtube"
                                   href="http://www.youtube.com/watch?v={{ video.id }}">{{ video.title }}</a></h2>
                        </div>
                    {% endfor %}
                {% else %}
                    <div class="article">
                        <p>Nothing</p>
                    </div>
                {% endif %}
            </div>
{% if is_paginated %}
        <div id="pages">
            <p> Pages:{% for num in page_obj.paginator.page_range %}
                {% ifequal num page_obj.number %}
                    <span class="current"><b>{{ num }}</b></span>
                {% else %}
                    <a href="?page={{ num }}"> {{ num }}</a>
                {% endifequal %}
            {% endfor %}

            </p>

我想手动获取视频数量并将其按页数划分，但我不知道如何实现它

Answer 1

好的，第一部分：获取视频（您需要一个 api-key，可能需要多个用于常规使用）：

这是 python 但你可以将它转换成你喜欢的任何东西，只要它可以发送 GET 请求：

注意：CC 定义是否查找创作共用视频 您还可以使用搜索查找视频

from requests import get
from random import choice

useSearch = True

fname = "output"

if useSearch :
    cc = False
    searchTerm = ""
    apiKeys = []
    apiKey = choice(apiKeys)
    url = "https://www.googleapis.com/youtube/v3/search"
    token = ""
    rDone = 0
    videos = []
    searching = True
    if cc :
        searchTerm = searchTerm + "&videoLicense=creativeCommon&type=video"
    while searching :
        print(url + "?key=" + apiKey + "&q=" + searchTerm + "&part=id&maxResults=50&pageToken=" + token)
        y = get(url + "?key=" + apiKey + "&q=" + searchTerm + "&part=id&maxResults=50&pageToken=" + token).json()
        if y['kind'] == "youtube#searchListResponse" :
            for x in y['items'] :
                if x['id']['kind'] == "youtube#video" :
                    videos.append(x['id']['videoId'])
        rDone = rDone + int(y['pageInfo']['resultsPerPage'])
        if int(y['pageInfo']['totalResults']) <= rDone :
            searching = False
        elif int(y['pageInfo']['resultsPerPage']) > int(y['pageInfo']['totalResults']) :
            searching = False
        else :
            try :
                token = y['nextPageToken']
            except :
                searching = False
else :
    cc = False
    channelID = ""
    apiKeys = ["AIzaSyBTV_7FVKuJBvFEPo1ZkLtXSl7w2Ulg6XY", "AIzaSyAzwkMIvLFYTYz5uHv-Idmq68Er_DzOEkI", "AIzaSyDPGSYUScf6j9A7uE1pWaXxK9j9TCGZbEs"]
    apiKey = choice(apiKeys)
    url = "https://www.googleapis.com/youtube/v3/search"
    token = ""
    rDone = 0
    videos = []
    searching = True
    if cc :
        channelID = channelID + "&videoLicense=creativeCommon&type=video"
    while searching :
        print(url + "?key=" + apiKey + "&channelId=" + channelID + "&part=id&order=date&maxResults=50&pageToken=" + token)
        y = get(url + "?key=" + apiKey + "&channelId=" + channelID + "&part=id&order=date&maxResults=50&pageToken=" + token).json()
        if y['kind'] == "youtube#searchListResponse" :
            for x in y['items'] :
                if x['id']['kind'] == "youtube#video" :
                    videos.append(x['id']['videoId'])
        rDone = rDone + int(y['pageInfo']['resultsPerPage'])
        if int(y['pageInfo']['totalResults']) <= rDone :
            searching = False
        elif int(y['pageInfo']['resultsPerPage']) > int(y['pageInfo']['totalResults']) :
            searching = False
        else :
            try :
                token = y['nextPageToken']
            except :
                searching = False
file = open(fname + ".txt", "w+")
for index in range(len(videos)) :
    video = videos[index]
    if len(videos) - 1 == index :
        file.write(video)
    else :
        file.write(video + "\n")
file.close()

接下来，您需要将输出分成列表。使用这样的东西：

ls = open("../output.txt", "r").read().split("\n")
def chunks(lst, n):
    """Yield successive n-sized chunks from lst."""
    for i in range(0, len(lst), n):
        yield lst[i:i + n]
pages = list(chunks(ls, 10))

Pages[0] 将是第一页

如果你想将它用于网页，你可以把它变成一个对 php 友好的东西并使用它
