    accessToken, err := idp.Session.Authorize(idp.Provider, value)
    if err != nil {
        return nil, err
    }

var token *oauth2.Token
            token, err = idProvider.GetToken(authForm.Code)
            if err != nil {
                c.ResponseError(err.Error())
                return
            }

            if !token.Valid() {
                c.ResponseError(c.T("auth:Invalid token"))
                return
            }
