サブスクリプショントークンのGoogle Android Subscription API有効期限を取得します。

Question

次のリクエストを行うと、Googleではエラー503しか表示せず、有用な情報を提供しません。

私はここにドキュメントを以下のよ：https://developers.google.com/android-publisher/v1/purchases/get

許可トークンが最近（自動的に）更新されます。 （通常、それが古くなったら401と表示されます）

@imrankhan Perlでこれを行う方法は次のとおりです。

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; 
    } 
}
