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))

Python中的示例解决方案。从这个视频中得到帮助:视频 与许多其他答案一样，上传id首先从通道id中检索。

import urllib.request
import json

key = "YOUR_YOUTUBE_API_v3_BROWSER_KEY"

#List of channels : mention if you are pasting channel id or username - "id" or "forUsername"
ytids = [["bbcnews","forUsername"],["UCjq4pjKj9X4W9i7UnYShpVg","id"]]

newstitles = []
for ytid,ytparam in ytids:
    urld = "https://www.googleapis.com/youtube/v3/channels?part=contentDetails&"+ytparam+"="+ytid+"&key="+key
    with urllib.request.urlopen(urld) as url:
        datad = json.loads(url.read())
    uploadsdet = datad['items']
    #get upload id from channel id
    uploadid = uploadsdet[0]['contentDetails']['relatedPlaylists']['uploads']

    #retrieve list
    urld = "https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=50&playlistId="+uploadid+"&key="+key
    with urllib.request.urlopen(urld) as url:
        datad = json.loads(url.read())

    for data in datad['items']:
        ntitle =  data['snippet']['title']
        nlink = data['contentDetails']['videoId']
        newstitles.append([nlink,ntitle])

for link,title in newstitles:
    print(link, title)

下面是一个不需要任何特殊包的Python替代方案。通过提供频道id，它将返回该频道的视频链接列表。请注意，你需要一个API密钥为它工作。

import urllib
import json

def get_all_video_in_channel(channel_id):
    api_key = YOUR API KEY

    base_video_url = 'https://www.youtube.com/watch?v='
    base_search_url = 'https://www.googleapis.com/youtube/v3/search?'

    first_url = base_search_url+'key={}&channelId={}&part=snippet,id&order=date&maxResults=25'.format(api_key, channel_id)

    video_links = []
    url = first_url
    while True:
        inp = urllib.urlopen(url)
        resp = json.load(inp)

        for i in resp['items']:
            if i['id']['kind'] == "youtube#video":
                video_links.append(base_video_url + i['id']['videoId'])

        try:
            next_page_token = resp['nextPageToken']
            url = first_url + '&pageToken={}'.format(next_page_token)
        except:
            break
    return video_links

获取频道列表:

通过forUserName获取频道列表:

https://www.googleapis.com/youtube/v3/channels?part=snippet,contentDetails,statistics&forUsername=Apple&key=

按频道id获取频道列表:

https://www.googleapis.com/youtube/v3/channels/?part=snippet,contentDetails,statistics&id=UCE_M8A5yxnLfW0KghEeajjw&key=

这里所有的api都是Get方法。

基于频道id，我们不能直接得到所有的视频，这是这里的重点。

对于集成https://developers.google.com/youtube/v3/quickstart/ios?ver=swift

下面是返回频道下所有视频id的代码

<?php 
    $baseUrl = 'https://www.googleapis.com/youtube/v3/';
    // https://developers.google.com/youtube/v3/getting-started
    $apiKey = 'API_KEY';
    // If you don't know the channel ID see below
    $channelId = 'CHANNEL_ID';

    $params = [
        'id'=> $channelId,
        'part'=> 'contentDetails',
        'key'=> $apiKey
    ];
    $url = $baseUrl . 'channels?' . http_build_query($params);
    $json = json_decode(file_get_contents($url), true);

    $playlist = $json['items'][0]['contentDetails']['relatedPlaylists']['uploads'];

    $params = [
        'part'=> 'snippet',
        'playlistId' => $playlist,
        'maxResults'=> '50',
        'key'=> $apiKey
    ];
    $url = $baseUrl . 'playlistItems?' . http_build_query($params);
    $json = json_decode(file_get_contents($url), true);

    $videos = [];
    foreach($json['items'] as $video)
        $videos[] = $video['snippet']['resourceId']['videoId'];

    while(isset($json['nextPageToken'])){
        $nextUrl = $url . '&pageToken=' . $json['nextPageToken'];
        $json = json_decode(file_get_contents($nextUrl), true);
        foreach($json['items'] as $video)
            $videos[] = $video['snippet']['resourceId']['videoId'];
    }
    print_r($videos);
