Ottieni l'ora di scadenza dell'API di abbonamento a Google Android per un token di abbonamento.

Question

Quando faccio la seguente richiesta, Google restituisce solo l'errore 503 e non fornisce alcuna informazione utile.

Sto seguendo la documentazione qui: https://developers.google.com/android-publisher/v1/purchases/get

Il token di autorizzazione è stato recentemente aggiornato (automaticamente). (Normalmente dice 401 quando è stantio.)

@imrankhan. Ecco come farlo in Perl:

sub refreshAccessToken { 
    my $ua = LWP::UserAgent->new; 
    my $req = HTTP::Request->new(POST => 'https://accounts.google.com/o/oauth2/token'); 
    $req->content_type('application/x-www-form-urlencoded'); 
    $req->content('grant_type=refresh_token&client_id=9999999.apps.googleusercontent.com&client_secret=xxxxxxxxxxxxxxxx&refresh_token='.$REFRESH_TOKEN); 
    # grant_type=refresh_token 
    # client_id=<the client ID token created in the APIs Console> 
    # client_secret=<the client secret corresponding to the client ID> 
    # refresh_token=<the refresh token from the very first authorization step> 
    my $res = $ua->request($req); 
    if ($res->is_success()) { # parse JSON 
     #print $res->content . "\n"; 
     # { 
      # "access_token" : "ya29.AHES3ZQ_MxxxxTeSl530Na2", 
      # "token_type" : "Bearer", 
      # "expires_in" : 3600, 
     # } 
     my $json = decode_json($res->content); 
     my $accessToken = $json->{'access_token'}; 
     saveAccessToken($accessToken); 
    } else { 
     serverError($ERROR_GOOGLE, 'Could not refresh subscription access token from Google server. '.$res->status_line); 
     exit; 
    } 
}
