Use response.headers() to get the content type:

var config = { responseType: 'blob' };

$http.get(itemsUrl, config).then(function onSuccess(response) {
    var blob = response.data;
    var contentType = response.headers("content-type");
    var fileURL = URL.createObjectURL(blob);
    window.open(fileURL); 
});

Consider using 'blob' as the responseType.
