HI ,
I have get Refresh Token and Access Token using oAuth and calandar events
Now i want to get the list of all Picasa album by Refresh or access token
using Google.GData API.
I get Refresh Token Like this
public static GoogleAuthenticator GetAuthenticator(string
authorizationCode, string _clientId, string _clientSecret, string
_redirectUri)
{
var client = new
NativeApplicationClient(GoogleAuthenticationServer.Description, _clientId,
_clientSecret);
IAuthorizationState state = new AuthorizationState() { Callback
= new Uri(_redirectUri) };
state = client.ProcessUserAuthorization(authorizationCode,
state);
var auth = new
OAuth2Authenticator<NativeApplicationClient>(client, (c) => state);
auth.LoadAccessToken();
return new GoogleAuthenticator(auth);
}
public static GoogleAuthenticator RefreshAuthenticator(string
refreshToken, string _clientId, string _clientSecret)
{
var state = new AuthorizationState(_scopes)
{
RefreshToken = refreshToken
};
var client = new
NativeApplicationClient(GoogleAuthenticationServer.Description, _clientId,
_clientSecret);
bool result = client.RefreshToken(state);
var auth = new
OAuth2Authenticator<NativeApplicationClient>(client, (c) => state);
auth.LoadAccessToken();
return new GoogleAuthenticator(auth);
}
public class GoogleAuthenticator
{
private OAuth2Authenticator<NativeApplicationClient> _authenticator;
public
GoogleAuthenticator(OAuth2Authenticator<NativeApplicationClient>
authenticator)
{
_authenticator = authenticator;
}
internal IAuthenticator Authenticator
{
get { return _authenticator; }
}
public bool IsValid
{
get
{
return _authenticator != null &&
DateTime.Compare(DateTime.Now.ToUniversalTime(),
_authenticator.State.AccessTokenExpirationUtc.Value) < 0;
}
}
public string RefreshToken
{
get { return _authenticator.State.RefreshToken; }
}
public string AccessToken
{
get { return _authenticator.State.AccessToken; }
}
}
To get the Picasa feed we need the username and password. but i want to
access this using refresh token.
I tried this
PhotoQuery query = new
PhotoQuery(PicasaQuery.CreatePicasaUri(txtUserName.Text,
e.CommandArgument.ToString()));
PicasaService service = new PicasaService("Picasa");
service.setUserCredentials("UserName", "Password");
PicasaFeed feed = service.Query(query);
but for above code i need to pass the Username and password every time. I
need this be done through Refresh Token.
Is It possible ?
Can you please suggest ?
