Angularjs注入拦截器实现Loading效果

<!-- lang: js -->
module.factory('myInterceptor', ['$log', function($log) {
 $log.debug('$log is here to show you that this is a regular factory with injection');
 var myInterceptor = {
  ....
  ....
  ....
 };
 return myInterceptor;
}]);

<!-- lang: js -->
module.config(['$httpProvider', function($httpProvider) {
 $httpProvider.interceptors.push('myInterceptor');
}]);
