angular method to uniformly handle http requests and responses with interceptors

Want to use the http in angularjs to send a request to the background. Now there is a token uniquely identified by the user who wants to put it in the headers, that is {headres:{'token':1}}

The following js are introduced:

('',[])
  .factory('httpInterceptor',['$q','$injector','$localStorage',function ($q,$injector,$localStorage) {
    var httpInterceptor = {
      'responseError' : function(response) {
        // ......
        return $(response);
      },
      'response' : function(response) {
        if ( == 21000) {
          // ('do something...');
        }
        return response || $(response);
      },
      'request' : function(config) {
         =  || {};
        if ($) {
           = $;
          // ['X-Access-Token'] = $;
        };

        return config || $(config);

        return config;
      },
      'requestError' : function(config){
        // ......
        return $(config);
      }
    };
    return httpInterceptor;
  }])

After injecting factory in the app, configure it in config

.config(['$httpProvider',function(){
  $(httpInterceptor);
}])

The above method of using an interceptor to uniformly handle http requests and responses is all the content I share with you. I hope you can give you a reference and I hope you support me more.
