Examples of com.google.api.client.http.HttpUnsuccessfulResponseHandler

com.google.api.client.http.HttpUnsuccessfulResponseHandler

Interface which handles abnormal HTTP responses (in other words not 2XX).

For example, this might be used to refresh an OAuth 2 token:

 public static class RefreshTokenHandler implements HttpUnsuccessfulResponseHandler { public boolean handleResponse( HttpRequest request, HttpResponse response, boolean retrySupported) throws IOException { if (response.statusCode == HttpStatusCodes.STATUS_CODE_UNAUTHORIZED) { refreshToken(); } return false; } }

Sample usage with a request factory:

 public static HttpRequestFactory createRequestFactory(HttpTransport transport) { final RefreshTokenHandler handler = new RefreshTokenHandler(); return transport.createRequestFactory(new HttpRequestInitializer() { public void initialize(HttpRequest request) { request.unsuccessfulResponseHandler = handler; } }); }

If you have a custom unsuccessful response handler, use this more complex example:

 public static HttpRequestFactory createRequestFactory(HttpTransport transport) { final RefreshTokenHandler handler = new RefreshTokenHandler(); return transport.createRequestFactory(new HttpRequestInitializer() { public void initialize(HttpRequest request) { request.unsuccessfulResponseHandler = new HttpUnsuccessfulResponseHandler() { public boolean handleResponse( HttpRequest request, HttpResponse response, boolean retrySupported) throws IOException { return handler.handleResponse(request, response, retrySupported); } }; } }); }

Implementations should normally be thread-safe.
