由于每个回答这个问题的人都有500个视频限制的问题，这里有一个使用Python 3中的youtube_dl的替代解决方案。此外，不需要API密钥。

安装youtube_dl: sudo pip3 Install youtube_dl 找出目标频道的频道id。ID将以UC开头。将Channel的C替换为Upload的U(即UU…)，这是上传播放列表。 使用youtube-dl的播放列表下载功能。理想情况下，你不希望下载播放列表中的每个视频，这是默认的，而只是元数据。

示例(警告—需要数十分钟):

import youtube_dl, pickle

             # UCVTyTA7-g9nopHeHbeuvpRA is the channel id (1517+ videos)
PLAYLIST_ID = 'UUVTyTA7-g9nopHeHbeuvpRA'  # Late Night with Seth Meyers

with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:

    playd = ydl.extract_info(PLAYLIST_ID, download=False)

    with open('playlist.pickle', 'wb') as f:
        pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)

    vids = [vid for vid in playd['entries'] if 'A Closer Look' in vid['title']]
    print(sum('Trump' in vid['title'] for vid in vids), '/', len(vids))

使用gapi JavaScript API可以做到这一点

<script src="https://apis.google.com/js/api.js"></script>

const start = () => {
  gapi.client
    .init({
      apiKey: "your_youtubeApiKey",
      discoveryDocs: ["https://www.googleapis.com/discovery/v1/apis/youtube/v3/rest"],
      scope: "https://www.googleapis.com/auth/youtube.readonly",
    })
    .then(() => {
      console.log("gapi.client initiated");
    })
    .then(() =>
      gapi.client.youtube.channels.list({
        part: "snippet,contentDetails,statistics",
        id: "youtube_channelId",
        // forUsername: 'Bankless',
      })
    )
    .then(
      (res) =>
        // get the youtube related playlist id
        res.result.items[0].contentDetails.relatedPlaylists.uploads
    )
    .then((playlistId) =>
      gapi.client.youtube.playlistItems.list({
        part: "snippet",
        playlistId,
        maxResults: 50,
      })
    )
    .then((res) =>
      // get youtube videos snippets
      res.result.items.map((item) => item.snippet)
    )
    .then((snippets) =>
      snippets.map((snippet) => {
        const { title, description, resourceId } = snippet;
        const { videoId } = resourceId;
        return { title, description, videoId };
      })
    )
    .then((videos) => {
      console.log(videos);
    })
    .catch((err) => console.error(err));
};
gapi.load("client", start);

这是我的Python解决方案，使用谷歌API。 观察:

创建一个.env文件来存储API开发密钥，并将其放入.gitignore文件中 参数“forUserName”应该设置为Youtube频道的名称(用户名)。或者，您可以使用通道id，设置参数为“id”，而不是“forUserName”。 对象“playlistItem”让你访问每个视频。我只展示了它的标题，但还有很多其他属性。

import os
import googleapiclient.discovery
from decouple import config
def main():
    os.environ["OAUTHLIB_INSECURE_TRANSPORT"] = "1"

    api_service_name = "youtube"
    api_version = "v3"
    DEVELOPER_KEY = config('API_KEY')

    youtube = googleapiclient.discovery.build(
        api_service_name, api_version, developerKey = DEVELOPER_KEY)

    request = youtube.channels().list(
        part="contentDetails",
        forUsername="username",
        # id="oiwuereru8987",
    )

    response = request.execute()
    for item in response['items']:
        playlistId = item['contentDetails']['relatedPlaylists']['uploads']
        nextPageToken = ''
        while (nextPageToken != None):
            playlistResponse = youtube.playlistItems().list(
                part='snippet',
                playlistId=playlistId,
                maxResults=25,
                pageToken=nextPageToken
            )
            playlistResponse = playlistResponse.execute()
            print(playlistResponse.keys())
            for idx, playlistItem in enumerate(playlistResponse['items']):
                print(idx, playlistItem['snippet']['title'])
            if 'nextPageToken' in playlistResponse.keys():
                nextPageToken = playlistResponse['nextPageToken']
            else:
                nextPageToken = None

if __name__ == "__main__":
    main()

示例:.env文件

API_KEY=<Key_Here>

使用已弃用的API版本2，用于上传的URL(通道UCqAEtEr0A0Eo2IVcuWBfB9g)是:

https://gdata.youtube.com/feeds/users/UCqAEtEr0A0Eo2IVcuWBfB9g/uploads

有一个API版本3。

只需三步:

订阅:list -> https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&maxResults=50&mine=true&access_token= {oauth_token} 通道:list -> https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id= {channel_id}关键= {YOUR_API_KEY} PlaylistItems: list -> https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId= {playlist_id}关键= {YOUR_API_KEY}
