I'm currently trying to use the new java client(s) and due to legacy reasons for current state of google libraries, I need to use both the gdata and the new google java client api.
Obviously I'd like to use OAuth2 -- however with OAuth2 I am not getting the access token secret -- which causes an issue b/c gdata requires the access token secret.
Could anyone pls advise on a workaround eg. - is there a way to use gdata java libraries with only access token(OAuth2) and not access token secret? Code examples(and attempt) do not corroborate this but perhaps I'm doing something incorrectly
Thanks
I found a solution. You can set a special HTTP-Header (Authorization: Bearer ACCESS_TOKEN) as documented in http://code.google.com/apis/accounts/docs/OAuth2WebServer.html#callinganapi
Once you have received your accessToken (e.g. like this http://code.google.com/p/google-api-java-client/wiki/OAuth2Draft10 ) you can call your "old" gdata service like this:
SpreadsheetService service = new SpreadsheetService("yourAppName");
service.setHeader("Authorization", "Bearer " + accessToken);
URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
SpreadsheetFeed feed = service.getFeed(metafeedUrl, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
for (int i = 0; i < spreadsheets.size(); i++) {
SpreadsheetEntry entry = spreadsheets.get(i);
System.out.println("\t" + entry.getTitle().getPlainText());
}
It's a bit odd that I couldn't find it really documented clearly. I just found it by coincidence.
