从控制器发送数据到工厂？

Question

my factory is:

 myAppServices.factory('ProfileData',['$http',  function($http){
            return{
            newly_joined:function(callback){
            $http.get(
//myUrl will be an url from controller.
                myUrl
            ).success(callback);
              }
    };

          }
                                            ]);

and I have three controller which has different URL:

controller1:

AppControllers.controller('ProfileListCtrl',['$scope','$state', '$rootScope', 'ProfileData', '$timeout',   function($scope, $state, $rootScope, ProfileData, $timeout ) {


    ProfileData.newly_joined(function(response) {
      var myUrl= "www.abc...." 
     //something goes there
});

     }]);

controller2:

AppControllers.controller('ProfileListCtrl1',['$scope','$state', '$rootScope', 'ProfileData', '$timeout',   function($scope, $state, $rootScope, ProfileData, $timeout ) {


    ProfileData.newly_joined(function(response) {
      var myUrl= "www.abc...." 
     //something goes there
});

     }]);

and controller 3 is:

AppControllers.controller('ProfileListCtrl2',['$scope','$state', '$rootScope', 'ProfileData', '$timeout',   function($scope, $state, $rootScope, ProfileData, $timeout ) {


    ProfileData.newly_joined(function(response) {
      var myUrl= "www.abc...." 
     //something goes there
});

     }]);

I want different data in different controller because of different URL and I am showing all three details on single web page.

So if there were any method to send 'myUrl' in factory that I can use that for pulling data.

Note: please don't suggest me for using $resource or $routeparams because $resource was not successfull in pulling data from json and I don't want to use big variable Url for my page.

Thanks in advance

Answer 1

All you need to do is add an additional parameter to the newly_joined function:

newly_joined:function(callback, myUrl){

Also, you should be using .then instead of .success

Answer 2

Your factory should be returning promises instead of using callbacks.

myAppServices.factory('ProfileData',['$http',  function($http){
    return function(myUrl) {
        return $http.get(myUrl);
    };
}]);

The controller

AppControllers.controller('ProfileListCtrl',['$scope', 'ProfileData', function($scope,ProfileData) {

    var myUrl= "www.abc....";
    var httpPromise = ProfileData(myUrl);

    httpPromise.then(function onFulfilled(response) {
        $scope.data = response.data;
    }).catch(function onRejected(response) {
        console.log("ERROR ", response.status);
    });

}]);

The DEMO on JSFiddle

The advantage of using promises is that they retain error information.

Also notice that myUrl is sent to the factory as an argument.
