Batch request with youtube api - get the latest video information from multiple channels

Question

I have 10 youtube channels that I like and I want to get the latest video information for each channel. Right now i'm doing 10 different calls like this one:

http://gdata.youtube.com/feeds/api/users/USERNAME/uploads?v=2&alt=jsonc&start-index=1&max-results=1

I want to replace those 10 calls with a single one by using a batch request.

I tryed this:

String xml = "<feed xmlns='http://www.w3.org/2005/Atom' xmlns:batch='http://schemas.google.com/gdata/batch'>" +
             "    <batch:operation type='query'/>" +
             "    <entry>" +
             "        <id>http://gdata.youtube.com/feeds/api/videos/VIDEO_ID_1</id>" +
             "    </entry>" +
             "    <entry>" +
             "        <id>http://gdata.youtube.com/feeds/api/videos/VIDEO_ID_2</id>" +
             "    </entry>" +
             ...
             "    <entry>" +
             "        <id>http://gdata.youtube.com/feeds/api/videos/VIDEO_ID_10</id>" +
             "    </entry>" +
             "</feed>";

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("https://gdata.youtube.com/feeds/api/videos/batch?v=2");
StringEntity se = new StringEntity(xml);
se.setContentType("text/xml");
httpPost.setEntity(se);
HttpResponse response = httpClient.execute(httpPost);

I'm getting a XML with usefull data in the HTTPResponse object.

But if I want to get the 10 latest videos information, I won't know the videoId.

Does anybody know how to achieve this ?

Answer 1

You can't make a batch request that includes 10 different http://gdata.youtube.com/feeds/api/users/USERNAME/uploads?v=2 URLs in the request body.

You would need to request http://gdata.youtube.com/feeds/api/users/USERNAME/uploads?v=2&max-results=1 10 times, once with each USERNAME.

Alternatively, if you have some sort server-side process that's interested in finding out when new videos are uploaded to a given channel, you can use either PubSubHubbub or SUP to handle that scenario more efficiently. Because your question was tagged with android I'm assuming that you care about doing this client-side, though.
