I am trying to use Picasa API by authenticating via OAuth 2.0
Below are the params I am using
scope: http://picasaweb.google.com/data/
feed: "http://picasaweb.google.com/data/feed/api/user/default";
After authorization, In the callback I am creating a PicasaWebService
and trying to get all the album entries.
Album entries are always empty.
I am able to create a new album though.
Any idea what could go wrong?
Below is the code in authorization callback
GoogleOAuthParameters gOAuthParams = new GoogleOAuthParameters();
gOAuthParams.setOAuthConsumerKey(OAUTH_CLIENT_ID);
gOAuthParams.setOAuthConsumerSecret(OAUTH_CLIENT_SECRET);
GoogleOAuthHelper gOAuthHelper = new GoogleOAuthHelper(new
OAuthHmacSha1Signer());
gOAuthHelper.getOAuthParametersFromCallback(req.getQueryString(),
gOAuthParams);
//fetch all cookies
Cookie[] cookies = req.getCookies();
Cookie secretToken = null;
if (cookies != null) {
for (int i = 0; i < cookies.length; i++) {
String cookieName = cookies[i].getName();
if (cookieName.equals("Secret_Token")) {
secretToken = cookies[i];
break;
}
}
}
gOAuthParams.setOAuthTokenSecret(secretToken.getValue());
PicasawebService pws = new PicasawebService("Text Mashup");
pws.setOAuthCredentials(gOAuthParams, new OAuthHmacSha1Signer());
UserFeed userFeed = pws.getFeed(new URL("http://picasaweb.google.com/
data/feed/api/user/default"), UserFeed.class);
List<AlbumEntry> albums = userFeed.getAlbumEntries(); //albums is
always empty-- why?
