my AJAX GET request

$http({
    method: 'GET',
    url: '/4740886&sz=320x50&c=1'
  }).then(function successCallback(response) {
      $scope.resp = response;
    }, function errorCallback(response) {
      console.log(response);
      
    });

gives this error :

data: "<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n<meta charset=\"utf-8\">\n<title>Error</title>\n</head>\n<body>\n<pre>Cannot GET /4740886&amp;sz=320x50&amp;c=1</pre>\n</body>\n</html>\n"
