I have been using the picasa client login for a couple of years without
issue. We use it to store photos that users upload so we do not want to
request for user authentication as we are just storing the photos in our
own account. It is developed in .NET.
Up until today it has worked and I can’t work out (and beginning to wander
whether it is now possible) how to fix the issue.
*Previous Code:*
PicasaService service = new PicasaService("My App");
service.setUserCredentials("[email protected]", "password");
Uri postUri = new Uri(PicasaQuery.CreatePicasaUri("default", AlbumID));
string sContentType = "image/jpeg";
PicasaEntry entry = (PicasaEntry)service.Insert(postUri, fileStream,
sContentType, sFilename);
fileStream.Close();
sPicasaURL = entry.Media.Content.Url.ToString();
*NEW CODE (that doesn’t work!)*
Uri postUri = new Uri(PicasaQuery.CreatePicasaUri("default", AlbumID));
const string ServiceAccountEmail = "[email protected]";
var certificate = new X509Certificate2(HttpContext.Current.Server.MapPath(
"bin/key2.p12"), "notasecret", X509KeyStorageFlags.Exportable);
var serviceAccountCredentialInitializer = new ServiceAccountCredential.
Initializer(ServiceAccountEmail)
{
Scopes = new[] {
"https://picasaweb.google.com/data/"; }
}.FromCertificate(certificate);
var credential = new ServiceAccountCredential
(serviceAccountCredentialInitializer);
if (!credential.RequestAccessTokenAsync(System.Threading.CancellationToken
.None).Result)
throw new InvalidOperationException("Access token
request failed.");
var requestFactory = new GDataRequestFactory(null);
requestFactory.CustomHeaders.Add("Authorization: Bearer " +
credential.Token.AccessToken);
PicasaService service = new PicasaService("My App");
service.RequestFactory = requestFactory;
string sContentType = "image/jpeg";
PicasaEntry entry = (PicasaEntry)service.Insert(postUri, fileStream,
sContentType, sFilename);
fileStream.Close();
sPicasaURL = entry.Media.Content.Url.ToString();
Please can you let me know why this doesn’t work? I simply get :
"The remote server returned an error: (404) Not Found." error.
{"Execution of request failed:
https://picasaweb.google.com/data/feed/api/user/default/albumid/myalbumid"}
Is this type of login even now possible with the clientlogin deprecated?
