javascript - 如何解决 Angularjs TypeError : Cannot read property 'push' of undefined?

Question

我正在使用 angularjs，当我启动我的应用程序时，出现错误:

TypeError: Cannot read property 'push' of undefined

这是我的代码:

   app.config([ '$routeProvider','$locationProvider', '$httpProvider', function($routeProvider, $httpProvider,$locationProvider) {


    $httpProvider.interceptors.push(function ($q, $rootScope, $location) {
            return {
                'responseError': function(rejection) {
                    var status = rejection.status;
                    var config = rejection.config;
                    var method = config.method;
                    var url = config.url;

                    if (status == 401) {
                        $location.path( "/login" );
                    } else {
                        $rootScope.error = method + " on " + url + " failed with status " + status;
                    }

                    return $q.reject(rejection);
                }
            };
        });


    $httpProvider.interceptors.push(function ($q, $rootScope, $location) {
        return {
            'request': function(config) {
                if (angular.isDefined($rootScope.authToken)) {
                    var authToken = $rootScope.authToken;
                        config.headers['X-Auth-Token'] = authToken;
                    }
                return config || $q.when(config);
            }
        };
    }
);

}]);

我不明白为什么会出现这个错误

您的注入(inject)顺序错误。您将 $locationProvider 放在数组中 $httpProvider 之前，因此您需要在参数中使用相同的顺序:

app.config([ '$routeProvider','$locationProvider', '$httpProvider', 
function($routeProvider, $locationProvider, $httpProvider) {});
