Role Based Access Control in AngularJS Blur-Admin template

问题

How to implement Role Based Access Control in Blur-Admin template for angularJS? Where to define roles? Which files are concerned?

Perfect and Working Solution! This solution basically provides restricted access to the roles allowed for that component.

define params in all of your main modules in this way - (for example) -

(function() {
  'use strict';

  angular.module('BlurAdmin.pages.components', [
      'BlurAdmin.pages.components.mail',
      // 'BlurAdmin.pages.components.timeline',
      // 'BlurAdmin.pages.components.tree',
      // 'BlurAdmin.pages.components.fileUpload',
    ])
    .config(routeConfig);

  /** @ngInject */
  function routeConfig($stateProvider) {
    $stateProvider
      .state('main.components', {
        url: '/components',
        template: '<ui-view  autoscroll="true" autoscroll-body-top></ui-view>',
        abstract: true,
        title: 'Components',
        sidebarMeta: {
          icon: 'ion-gear-a',
          order: 100,
        },
        authenticate: true,
        params: {                // <-- focusing this one
          authRoles: ['admin']   // <-- roles allowed for this module
        }
      });
  }
})();

Modify baSidebar.service.js, add a new function getAuthorizedMenuItems just below getMenuItems (for easy understanding). And then just add a single parameter authRoles in defineMenuItemStates().

So, getAuthorizedMenuItems() will contain following code -

this.getAuthorizedMenuItems = function(user) {
    var states = defineMenuItemStates();
    var menuItems = states.filter(function(item) {
        return item.level == 0 && _.includes(item.authRoles, user.role);
    });

    menuItems.forEach(function(item) {
        var children = states.filter(function(child) {
            return child.level == 1 && child.name.indexOf(item.name) === 0;
        });
        item.subMenu = children.length ? children : null;
    });

    return menuItems.concat(staticMenuItems);
};

And updated defineMenuItemStates() will be -

function defineMenuItemStates() {
    return $state.get()
        .filter(function(s) {
            return s.sidebarMeta;
        })
        .map(function(s) {
            var meta = s.sidebarMeta;
            return {
                name: s.name,
                title: s.title,
                level: ((s.name.match(/\./g) || []).length - 1),
                order: meta.order,
                icon: meta.icon,
                stateRef: s.name,
                authRoles: s.params ? s.params.authRoles : undefined        // <-- added this
            };
        })
        .sort(function(a, b) {
            return (a.level - b.level) * 100 + a.order - b.order;
        });
}

Now, it's time to use the newly added method getAuthorizedMenuItems in BaSidebarCtrl.js. Use it this way -

// FYI, I got userCreds in BaSidebarCtrl as following -
var userCreds = localStorage.getObject('dataUser');
// note that getMenuItems is just replaced with getAuthorizedMenuItems(userCreds)
// $scope.menuItems = baSidebarService.getMenuItems();
$scope.menuItems = baSidebarService.getAuthorizedMenuItems(userCreds);

So, your user object will look something like this -

var userCreds = {
    userName: 'test@mail.com',
    passWord: 'testpwd',
    role: 'admin'
};

That's it!
