为什么angular 1.5路线会破坏控制器？

Question

angular.module('CalendarTest')
      .config(function($routeProvider){
        $routeProvider.when('/signup', {
          templateUrl: '/signup.html'
        })
        $routeProvider.when('/login', {
          templateUrl: '/login.html'
        })
        $routeProvider.when('/testPage', {
          templateUrl: '/testPage.html'
        })
        $routeProvider.when('/visitform', {
          templateUrl: '/visitform.html'
        })
      });

路由器在索引加载时加载错误。

angular.module('formLoginApp', ['ngCookies'])
  .controller('formLoginController', ['$scope', '$cookies', ($scope, $cookies) => {
    $scope.email = '';
    $scope.password = '';
    $scope.update = (user) => {
      const req = new XMLHttpRequest();
      req.open('POST', 'http://localhost:4002/login', true);
      req.onload = (serverResponse) => {
        if (req.readyState === 4) {
          if (req.status === 200) {
            $cookies.put("user", req.response);
          } else {
            console.log('no response');
          }
        } else {
          console.log('no response');
        }
      };
      req.setRequestHeader("Authorization", "Negotiate");
      req.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
      req.send(JSON.stringify(user));
    };
  }]);

当我尝试访问此页面login.html时，我得到formLoginController不是一个（这里没什么......）。我不确定为什么会这样。我尝试简化问题并从文档添加控制器，但也破坏了。我该如何解决这个问题？
