Java 从Youtube官方频道获取视频

Youtube上有一些官方频道，如音乐、游戏、新闻等。我正在尝试获取这些频道的信息，好像这是一个普通频道，但它给我发送了无效的响应。这可能是因为频道视频不归频道所有，即使频道将其显示为“上传视频”。这是我的代码，用于“正常”频道：（

stringid

表示每个视频的id以逗号分隔）

此方法提供频道视频的视频，并与“正常”频道一起使用

public static ArrayList<VideoYoutube> getVideos (String ids) throws IOException
{
    try
    {
        YouTube.Videos.List videos = youtube.videos().list("id,snippet,statistics");

        videos.setKey(API_KEY);
        //Setting all the video ids we want to get back
        videos.setId(ids);
        videos.setMaxResults(RETURN_NUMBER);
        //Setting all the fields we want to be called from the api. Its such an
        videos.setFields("items(id,snippet/publishedAt,snippet/title,snippet/description," +
                    "snippet/thumbnails/default/url,snippet/thumbnails/medium/url,snippet/thumbnails/high/url," +
                    "snippet/channelId,snippet/channelTitle,statistics/viewCount,statistics/likeCount,statistics/dislikeCount," +
                    "statistics/favoriteCount,statistics/commentCount)");
        VideoListResponse videoResponse = videos.execute();

        List<Video> videoResultList = videoResponse.getItems();
}

public static String getChannelVideosIds(String channelId) throws IOException
{
    YouTube.Search.List search = youtube.search().list("id");
    //Define the search key
    search.setKey(API_KEY);
    search.setChannelId(channelId);
    //Give the type (video, playlist or channel)
    search.setType("video");
    //Giving the params we want to be returned comma separated(for example if we had choosed the snipped before, we could choose snipped fields like snipped/publishedAt)
    search.setFields("items(id)");
    //set the max return number
    search.setMaxResults(RETURN_NUMBER);
    //Execute the search query
    SearchListResponse searchResponse = search.execute();
    List<SearchResult> searchResultList = searchResponse.getItems();
    //check if the result is null
    return retrieveIds(searchResultList);
}

publicstaticarraylistgetvideos（stringid）抛出IOException
{
尝试
{
YouTube.Videos.List Videos=YouTube.Videos（）；
视频。设置键（API_键）；
//设置我们想要返回的所有视频ID
视频.setId（ids）；
videos.setMaxResults（返回\u编号）；
//设置我们希望从api调用的所有字段
设置字段（“项目（id、代码段/发布数据、代码段/标题、代码段/说明，”+
snippet/thumbnails/default/url、snippet/thumbnails/medium/url、snippet/thumbnails/high/url+
snippet/channelId、snippet/channelTitle、statistics/viewCount、statistics/likeCount、statistics/dislikeCount、+
“统计/收藏计数、统计/评论计数”）；
VideoListResponse videoResponse=videos.execute（）；
List videoResultList=videoResponse.getItems（）；
}

这是一种从我想要的频道检索视频ID的方法。它为这个频道提供null，但它使用的是“正常”频道

public static ArrayList<VideoYoutube> getVideos (String ids) throws IOException
{
    try
    {
        YouTube.Videos.List videos = youtube.videos().list("id,snippet,statistics");

        videos.setKey(API_KEY);
        //Setting all the video ids we want to get back
        videos.setId(ids);
        videos.setMaxResults(RETURN_NUMBER);
        //Setting all the fields we want to be called from the api. Its such an
        videos.setFields("items(id,snippet/publishedAt,snippet/title,snippet/description," +
                    "snippet/thumbnails/default/url,snippet/thumbnails/medium/url,snippet/thumbnails/high/url," +
                    "snippet/channelId,snippet/channelTitle,statistics/viewCount,statistics/likeCount,statistics/dislikeCount," +
                    "statistics/favoriteCount,statistics/commentCount)");
        VideoListResponse videoResponse = videos.execute();

        List<Video> videoResultList = videoResponse.getItems();
}

public static String getChannelVideosIds(String channelId) throws IOException
{
    YouTube.Search.List search = youtube.search().list("id");
    //Define the search key
    search.setKey(API_KEY);
    search.setChannelId(channelId);
    //Give the type (video, playlist or channel)
    search.setType("video");
    //Giving the params we want to be returned comma separated(for example if we had choosed the snipped before, we could choose snipped fields like snipped/publishedAt)
    search.setFields("items(id)");
    //set the max return number
    search.setMaxResults(RETURN_NUMBER);
    //Execute the search query
    SearchListResponse searchResponse = search.execute();
    List<SearchResult> searchResultList = searchResponse.getItems();
    //check if the result is null
    return retrieveIds(searchResultList);
}

公共静态字符串GetChannelVideoSID（字符串channelId）引发IOException
{
YouTube.Search.List Search=YouTube.Search（）.List（“id”）；
//定义搜索键
search.setKey（API_KEY）；
search.setChannelId（channelId）；
//提供类型（视频、播放列表或频道）
search.setType（“视频”）；
//给我们想要返回的参数以逗号分隔（例如，如果我们以前选择了剪切字段，我们可以选择剪切字段，如snipped/publishedAt）
search.setFields（“items（id）”）；
//设置最大返回编号
search.setMaxResults（返回\u编号）；
//执行搜索查询
SearchListResponse searchResponse=search.execute（）；
List searchResultList=searchResponse.getItems（）；
//检查结果是否为空
返回RetrieveId（searchResultList）；
}
