AngularJS: Encountering an issue with "function not defined" error

I'm encountering an error message saying "Base64.encode is not a function," but I'm unsure why:

The 'login-controller' controller below utilizes the LoginService:

    angular.module('app')
    .controller('login-controller',
     ['$scope', '$location', '$http', 'LoginService',  
     function($scope, $location, $http, LoginService) {
     ...
        if(LoginService.login($scope.user.name, $scope.user.password) == true)
        {
            $location.path('/chooseMandantAsk')
        }
        else
        {
            $scope.wrongCredentials = true;
        }
    ...
    }]);

The following LoginService makes use of a function from the Base64 Service:

angular.module('app')
       .service('LoginService', ['$location', '$http', 'Base64', function ($http, Base64) {

    ...

this.login = function (name, password){

            user.auth= "Basic " + Base64.encode(name + ":" + password);
            $http.defaults.headers.common.Authorization = user.auth;
            $http.get(url+'/login')
                .success(function(){  
                     return true;
                 })
                .error(function(){
                    user.auth = "";
                    delete $http.defaults.headers.common['Authorization'];
                    return false;
                });
        };

    ...

}]);

The Base64 service includes a method called encode:

angular.module('app').factory('Base64', function () {


    var keyStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=';

        return {
            encode: function (input) {

                ...

                return output;
            },
            decode: function (input) {

                ...

                return output;
            }
        };
 });

I have previously used the Base64.encode method in a different manner and it worked fine.

If anyone could assist me in understanding this error, I would greatly appreciate it.

Best regards,

Matthias

Answer №1

It seems like the issue lies in not including $location when injecting your dependencies -

service('LoginService', ['$location', '$http', 'Base64', function ($location, $http, Base64)

This could be the reason for the error you are encountering.

Answer №2

Make sure to include the $location dependency in your login service declaration:

angular.module('app')
       .service('LoginService', ['$location', '$http', 'Base64', function ($location, $http, Base64) {
