API

Service Methods

login(token: String, [user: Object, [permissions: Array]]) [Simple strategy]

Authenticate a user with token. Data and permissions are optional.
Simple example:

angular
  .module('myApp')
  .controller(['$scope', '$http', '$security', function ($scope, $http, $security) {
    $scope.username = 'admin';
    $scope.password = 'admin';
    $scope.authenticate = function () {
      $http.post('/api/auth', {
        username: $scope.username,
        password: $scope.password
      }).success(function (data) {
        $security.login(data.token, data.user, data.permissions);
      });
    }
  }]);

login(token: String, [permissions: Array]) [JWT strategy]

Authenticate a user with token. Permissions are optional.
JWT example:

/* file: app.js */
angular
  .module('myApp')
  .config(['$httpProvider', '$securityConfigProvider', function ($httpProvider, $securityConfigProvider) {
    $httpProvider.interceptors.push('$securityInterceptor');
    $securityConfigProvider.configure({
      strategy: 'jwt',
    });
  }])
  .controller(['$scope', '$http', '$security', function ($scope, $http, $security) {
    $scope.username = 'admin';
    $scope.password = 'admin';
    $scope.authenticate = function () {
      $http.post('/api/auth', {
        username: $scope.username,
        password: $scope.password
      }).success(function (data) {
        $security.login(data.token, data.permissions);
      });
    }
  }]);

loginByUrl(url: String, data: Object)

Use resource for authenticate user. The service should return a response compatible. The return is a promise.
Simple example:

angular
  .module('myApp')
  .controller(['$scope', '$security', function ($scope, $security) {
    $scope.username = 'admin';
    $scope.password = 'admin';
    $scope.authenticate = function () {
      $security.loginByUrl('/api/auth', {
        username: $scope.username,
        password: $scope.password
      }));
    }
  }]);

Compatible API response:

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9",  /* required */
  "user": {  /* optional */
    "name": 'Administrator'
  },
  "permissions": [  /* optional */
    'admin'
  ]
}

angular
  .module('myApp')
  .config(['$httpProvider', '$securityConfigProvider', function ($httpProvider, $securityConfigProvider) {
    $httpProvider.interceptors.push('$securityInterceptor');
    $securityConfigProvider.configure({
      strategy: 'jwt',
    });
  }])
  .controller(['$scope', '$security', function ($scope, $security) {
    $scope.username = 'admin';
    $scope.password = 'admin';
    $scope.authenticate = function () {
      $security.loginByUrl('/api/auth', {
