有一个名为angular-app的示例 Angular 应用程序做得很好。他们有一个安全服务,然后是一个工具栏部分和指令,根据状态显示事物。

从角度应用程序:
src/common/security/login/toolbar.tpl.html:
<ul class="nav pull-right">
<li class="divider-vertical"></li>
<li ng-show="isAuthenticated()">
<a href="#">{{currentUser.firstName}} {{currentUser.lastName}}</a>
</li>
<li ng-show="isAuthenticated()" class="logout">
<form class="navbar-form">
<button class="btn logout" ng-click="logout()">Log out</button>
</form>
</li>
<li ng-hide="isAuthenticated()" class="login">
<form class="navbar-form">
<button class="btn login" ng-click="login()">Log in</button>
</form>
</li>
</ul>
src/common/security/login/toolbar.js:
angular.module('security.login.toolbar', [])
// The loginToolbar directive is a reusable widget that can show login or logout buttons
// and information the current authenticated user
.directive('loginToolbar', ['security', function(security) {
var directive = {
templateUrl: 'security/login/toolbar.tpl.html',
restrict: 'E',
replace: true,
scope: true,
link: function($scope, $element, $attrs, $controller) {
$scope.isAuthenticated = security.isAuthenticated;
$scope.login = security.showLogin;
$scope.logout = security.logout;
$scope.$watch(function() {
return security.currentUser;
}, function(currentUser) {
$scope.currentUser = currentUser;
});
}
};
return directive;
}]);
