【ANDROID】如何從YouTube獲取播放列表視訊
我正在編寫一個要在其中獲取YouTube視訊列表的應用程式,並且可以通過使用特定使用者的帳戶(例如以下連結)來做到這一點:
HttpUriRequest request = new HttpGet("http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads?v=2&alt=jsonc");
但是,如果我想使用播放列表來獲取YouTube視訊的列表,那麼我需要對程式碼進行哪些更改,例如在這裡,我不需要使用者名稱即可提取視訊。
http://gdata.youtube.com/feeds/api/playlists/PL1D5B07DD840FB46D?v=2&alt=json
原始連結:http://www.youtube.com/playlist?list=PL1D5B07DD840FB46D
我的程式碼:
public class GetYouTubeUserVideosTask implements Runnable {
public static final String LIBRARY = "Library";
private final Handler replyTo;
private final String username;
public GetYouTubeUserVideosTask(Handler replyTo, String username) {
this.replyTo = replyTo;
this.username = username;
}
@Override
public void run() {
try {
HttpClient client = new DefaultHttpClient();
HttpUriRequest request = new HttpGet("http://gdata.youtube.com/feeds/api/playlists/PL1D5B07DD840FB46D?v=2&alt=json");
HttpResponse response = client.execute(request);
String jsonString = StreamUtils.convertToString(response.getEntity().getContent());
JSONObject json = new JSONObject(jsonString);
JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");
List<Video> videos = new ArrayList<Video>();
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String title = jsonObject.getString("title");
String url;
try {
url = jsonObject.getJSONObject("player").getString("default");
} catch (JSONException ignore) {
url = jsonObject.getJSONObject("player").getString("default");
}
String thumbUrl = jsonObject.getJSONObject("thumbnail").getString("sqDefault");
videos.add(new Video(title, url, thumbUrl));
}
Library lib = new Library(username, videos);
Bundle data = new Bundle();
data.putSerializable(LIBRARY, lib);
Message msg = Message.obtain();
msg.setData(data);
replyTo.sendMessage(msg);
} catch (ClientProtocolException e) {
Log.e("Feck", e);
} catch (IOException e) {
Log.e("Feck", e);
} catch (JSONException e) {
Log.e("Feck", e);
}
}
}
解決辦法
您可以使用新的YouTube資料API v3來獲取播放列表:
https://developers.google.com/youtube/v3/docs/playlists
在我寫的本教程中(西類牙語..但您可以看到程式碼更改..):

我展示瞭如何更改官方示例“tasks-android-sample”:

使用YouTube資料API而不是任務API。
