   This is Controller page

        var myapp = angular.module('myApp', ['ngRoute']);

        myapp.config(["$routeProvider", function($routeProvider) {
            $routeProvider
            .when('/', {
                controller: 'loginctrl',
                templateUrl: 'login.html'
            })
            .when('/addusers', {
                controller: 'addusersctrl',
                templateUrl: 'addusers.html'
            })
            .otherwise({
                redirectTo: '/'
            });            
        }]);

        myapp.controller('loginctrl',['$scope', '$route', '$routeParams', '$location',function($scope,$http,$location){
            console.log("im a controller");            

            $scope.login = function() {
                //console.log($scope.user);

                // $http.post('/login',$scope.user).success(function(response){
                //  console.log(response);
                // });

                $http({
                      method: 'post',
                      url: '/login',
                      data: $scope.user 
                    }).then(function successCallback(response) {
                        // this callback will be called asynchronously
                        // when the response is available

                        console.log(response.data);
                        //$window.location.href = 'addusers.html';
                         $location.path("/addusers");
                    }, function errorCallback(response) {

                        console.log(response.data);
                        // called asynchronously if an error occurs
                        // or server returns response with an error status.
                    });            
            };
        }]);            

        myapp.controller('addusersctrl',['$scope','$http',function($scope,$http){
            console.log("im a controller");           

            $scope.login = function() {
                //console.log($scope.user);

                // $http.post('/login',$scope.user).success(function(response){
                //  console.log(response);
                // });

                $http({
                      method: 'post',
                      url: '/login',
                      data: $scope.user 
                    }).then(function successCallback(response) {
                        // this callback will be called asynchronously
                        // when the response is available

                        console.log(response.data);
                        //$window.location.href = 'addusers.html';

                    }, function errorCallback(response) {

                        console.log(response.data);
                        // called asynchronously if an error occurs
                        // or server returns response with an error status.
                    });            
            };
        }]);

每当我尝试运行此代码时，我都会

dependency injection（第一个控制器）出现问题：

myapp.controller('loginctrl', ['$scope', '$route', '$routeParams', '$location', 
                 function($scope, $http, $location) {

你没有注射相同的东西。将其更改为：

myapp.controller('loginctrl', ['$scope', '$route', '$http', '$routeParams', '$location', 
                 function($scope, $route, $http, $routeParams, $location) {
