Hi, I am trying to user picasaweb api to list a users photo albums
while get the following error.
GooglePhotosException: (403L, 'Forbidden', 'Token invalid - AuthSub
token has wrong scope')
The application is running on GAE server, the main hander is given as
follows.
Dose anyone know how to solve the problem?
class Hander(webapp.RequestHandler):
def get(self):
next = 'http://%s' %settings.HOST_NAME
scope = 'http://picasaweb.google.com/data/'
photo_service = gdata.photos.service.PhotosService()
single_use_token =
gdata.auth.extract_auth_sub_token_from_url(self.request.uri)
if single_use_token is None:
auth_url =
photo_service.GenerateAuthSubURL(next,scope,secure=False,session=True)
self.response.headers['Content-Type'] = 'text/html'
res = "<html><head><title>List Picasaweb Album</title></
head><body>\
<a href=%s>Login In</a></body></html>" %auth_url
self.response.out.write(res)
else:
photo_service.SetAuthSubToken(single_use_token)
photo_service.UpgradeToSessionToken()
#albums = photo_service.GetFeed('/data/feed/api/user/
defaut?kind=album')
albums = photo_service.GetUserFeed()
self.response.headers['Content-Type'] = 'text/plain'
res = ''
for album in albums.entry:
res += 'title: %s, number: %s: id: %s\n' %
(album.title.text,album.numphotos.text,album.gphoto_id.text)
self.response.out.write(res)
