我正在尝试为我的AngularJS应用程序编写HTTP拦截器来处理身份验证.

这段代码有效,但我担心手动注入服务,因为我认为Angular应该自动处理:

    app.config(['$httpProvider', function ($httpProvider) {
    $httpProvider.interceptors.push(function ($location, $injector) {
        return {
            'request': function (config) {
                //injected manually to get around circular dependency problem.
                var AuthService = $injector.get('AuthService');
                console.log(AuthService);
                console.log('in request interceptor');
                if (!AuthService.isAuthenticated() && $location.path != '/login') {
                    console.log('user is not logged in.');
                    $location.path('/login');
                }
                return config;
            }
        };
    })
}]);

我开始做的事情,但遇到循环依赖问题:

    app.config(function ($provide, $httpProvider) {
    $provide.factory('HttpInterceptor', function ($q, $location, AuthService) {
        return {
            'request': function (config) {
                console.log('in request interceptor.');
                if (!AuthService.isAuthenticated() && $location.path != '/login') {
                    console.log('user …
