身份验证：(404，"未找到"，"未知用户"。

Question

我尝试使用Picasa API与AuthSub。我的代码:

GD_CLIENT = gdata.photos.service.PhotosService()
def login(request):
    def GetAuthSubUrl():
        callback = 'http://127.0.0.1:8000/callback'
        scope = 'https://picasaweb.google.com/data/'
        secure = False
        session = True
        return GD_CLIENT.GenerateAuthSubURL(callback, scope, secure, session)
    auth_sub_url = GetAuthSubUrl()
    return HttpResponseRedirect(auth_sub_url)

def confirm(request):
    authsub_token = request.GET['token']    
    token = GD_CLIENT.SetAuthSubToken(authsub_token)
    GD_CLIENT.UpgradeToSessionToken()
    GD_CLIENT.auth_token = token
    return direct_to_template(request, 'base.djhtml')

def add_album(request):
   form = AddAlbum(request.POST or None)
   if form.is_valid():
       data = form.cleaned_data
       title = data.get('title')
       summary = data.get('summary')
       GD_CLIENT.InsertAlbum(title=title, summary=summary)
       return HttpResponseRedirect('/get_albums/')
   return render(request, 'add_form.djhtml', {'form': form})

我在add_album:

得到一个错误

(404， 'Not Found'， 'Unknown user.')

回溯:文件"/home/i159/Envs/photorulez/lib/python2.6/site-packages/django/core/handlers/base.py111. Response = callback(request， *callback_args， **callback_kwargs)文件"/home/i159/workspace/photoulez/photoulez/photoapp/views.py49. GD_CLIENT。InsertAlbum(标题、总结= =总结)文件"/home/i159/Envs/photorulez/lib/python2.6/site-packages/gdata/photos/service.py358. 提高GooglePhotosException (e.args [0])

异常类型:GooglePhotosException at/add_album/异常值:(404，'Not Found'， 'Unknown user.')

为什么要抬高?需要做哪些改变?

Answer 1

我明白了!GD_CLIENT = gdata.photos.service.PhotosService()需要email关键字参数作为Google帐户用户名。

gdata.photos.sevice.py

class PhotosService(gdata.service.GDataService):
  ssl = True
  userUri = '/data/feed/api/user/%s'
  def __init__(self, email=None, password=None, source=None,
           server='picasaweb.google.com', additional_headers=None,
           **kwargs):

所以应该是:

GD_CLIENT = gdata.photos.service.PhotosService(email='username')

Answer 2

这是我验证用户是否有会话令牌的函数:

def get_client(authsub_token):
    gd_client = gdata.photos.service.PhotosService(email='default')
    gd_client.SetAuthSubToken(authsub_token)
    return gd_client

如果您将电子邮件或用户名设置为"默认"，他将使用授权令牌的用户
