Question

$q.all - successfully resolving some HTTP requests while encountering errors on others

I encountered a coding scenario like this

angular.forEach(config.tvshows.shows, function(show) {
      promises.push($http.get('http://epguides.frecar.no/show/' + show.replace(/\s|\./g, '') + '/next/'));
  });

  return $q.all(promises).then(function(response) {
        for (var i = 0; i < response.length; i++) {
           service.shows.push(response[i]);
        }
  });
};

In this setup, I am collating a list of http requests called 'promises'. While most requests are successful, some may fail. It is crucial not to remove the failing request as it might succeed later.

Nevertheless, when a response fails, none of the responses are being stored in 'service.shows'. Is there a way to manage a 404 error or any other error response generated by an http request so that the code can proceed smoothly with the functioning requests?

Answer №1

To handle failed HTTP requests individually, you can implement a custom handler as shown below:

angular.forEach(config.tvshows.shows, function(show) {
      promises.push($http.get('http://epg\./g, ') + '/next/').catch(function() {
    // define your action for failed request here
}));

  });

This approach allows you to provide a specific response when a request fails, ensuring that the $q.all chain continues without interruption. If the request is successful, the server's response will be returned as expected.
