AngularJS-每个路由和控制器中的登录和身份验证

标签: javascript ruby-on-rails angularjs angularjs-authentication

我有一个使用yeoman,grunt和bower创建的AngularJS应用程序。

我有一个登录页面,其中包含一个检查身份验证的控制器。如果凭据正确,我会重新路由到主页。

app.js

'use strict';
//Define Routing for app
angular.module('myApp', []).config(['$routeProvider', '$locationProvider',
  function($routeProvider,$locationProvider) {
    $routeProvider
    .when('/login', {
        templateUrl: 'login.html',
        controller: 'LoginController'
    })
    .when('/register', {
        templateUrl: 'register.html',
        controller: 'RegisterController'
      })
    .when('/forgotPassword', {
        templateUrl: 'forgotpassword.html',
        controller: 'forgotController'
      })
   .when('/home', {
       templateUrl: 'views/home.html',
       controller: 'homeController'
    })
    .otherwise({
       redirectTo: '/login'
    });
//    $locationProvider.html5Mode(true); //Remove the '#' from URL.
}]);

angular.module('myApp').factory("page", function($rootScope){
    var page={};
    var user={};
    page.setPage=function(title,bodyClass){
        $rootScope.pageTitle = title;
        $rootScope.bodylayout=bodyClass;
    };
    page.setUser=function(user){
        $rootScope.user=user;
    }
    return page;
});

LoginControler.js

'use strict';

angular.module('myApp').controller('LoginController', function($scope, $location, $window,page) {
    page.setPage("Login","login-layout");
    $scope.user = {};
    $scope.loginUser=function()
    {
        var username=$scope.user.name;
        var password=$scope.user.password;
        if(username=="admin" && password=="admin123")
        {
            page.setUser($scope.user);
            $location.path( "/home" );
        }
        else
        {
            $scope.message="Error";
            $scope.messagecolor="alert alert-danger";
        }
    }
});

在主页上我有

<span class="user-info">
    <small>Welcome,</small>
    {{user.name}}
</span>
<span class="logout"><a href="" ng-click="logoutUser()">Logout</a></span>

loginController中,我检查登录信息,如果成功,我在服务工厂中设置用户对象。我不知道这是否正确。

我需要的是,当用户登录时,它在用户对象中设置一些值,以便所有其他页面都可以获得该值。

每当发生任何路由更改时,控制器都应检查用户是否已登录。如果没有,它应该重新路由到登录页面。此外,如果用户已登录并返回页面,则应转到主页。控制器还应检查所有路由上的凭证。

我听说过ng-cookies,但我不知道如何使用它们。

我看到的许多例子都不是很清楚,他们使用某种访问角色或其他东西。我不希望这样。我只想要一个登录过滤器。 有人可以给我一些想法吗?

9 个答案:

答案 0 :(得分:179)

我的解决方案分为3部分:用户的状态存储在服务中,在路由更改时您观察的运行方法中,并检查是否允许用户访问主控制器中的请求页面你看是否用户的状态发生了变化。

app.run(['$rootScope', '$location', 'Auth', function ($rootScope, $location, Auth) {
    $rootScope.$on('$routeChangeStart', function (event) {

        if (!Auth.isLoggedIn()) {
            console.log('DENY');
            event.preventDefault();
            $location.path('/login');
        }
        else {
            console.log('ALLOW');
            $location.path('/home');
        }
    });
}]);

您应该创建一个服务(我将其命名为Auth),该服务将处理用户对象并提供一种方法来了解用户是否已记录。

<强>服务

 .factory('Auth', function(){
var user;

return{
    setUser : function(aUser){
        user = aUser;
    },
    isLoggedIn : function(){
        return(user)? user : false;
    }
  }
})

从您的app.run,您应该听取$routeChangeStart事件。当路由发生变化时,它将检查用户是否已记录(isLoggedIn方法应该处理它)。如果用户未登录,它将不会加载请求的路由,并且会将用户重定向到右侧页面(在您登录的情况下)。

应在您的登录页面中使用loginController来处理登录。它应该只是与Auth服务相互作用,并将用户设置为已记录或不记录。

<强>的LoginController

.controller('loginCtrl', [ '$scope', 'Auth', function ($scope, Auth) {
  //submit
  $scope.login = function () {
    // Ask to the server, do your job and THEN set the user

    Auth.setUser(user); //Update the state of the user in the app
  };
}])

从主控制器,您可以监听用户状态是否发生变化并对重定向作出反应。

.controller('mainCtrl', ['$scope', 'Auth', '$location', function ($scope, Auth, $location) {

  $scope.$watch(Auth.isLoggedIn, function (value, oldValue) {

    if(!value && oldValue) {
      console.log("Disconnect");
      $location.path('/login');
    }

    if(value) {
      console.log("Connect");
      //Do something when the user is connected
    }

  }, true);

这是另一种可能的解决方案,使用$stateProvider$routeProviderresolve属性。 $stateProvider的示例:

.config(["$stateProvider", function ($stateProvider) {

  $stateProvider

  .state("forbidden", {
    /* ... */
  })

  .state("signIn", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAnonymous(); }],
    }
  })

  .state("home", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.isAuthenticated(); }],
    }
  })

  .state("admin", {
    /* ... */
    resolve: {
      access: ["Access", function (Access) { return Access.hasRole("ROLE_ADMIN"); }],
    }
  });

}])

Access根据当前用户权限解析或拒绝承诺:

.factory("Access", ["$q", "UserProfile", function ($q, UserProfile) {

  var Access = {

    OK: 200,

    // "we don't know who you are, so we can't say if you're authorized to access
    // this resource or not yet, please sign in first"
    UNAUTHORIZED: 401,

    // "we know who you are, and your profile does not allow you to access this resource"
    FORBIDDEN: 403,

    hasRole: function (role) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasRole(role)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    hasAnyRole: function (roles) {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$hasAnyRole(roles)) {
          return Access.OK;
        } else if (userProfile.$isAnonymous()) {
          return $q.reject(Access.UNAUTHORIZED);
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAnonymous: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAnonymous()) {
          return Access.OK;
        } else {
          return $q.reject(Access.FORBIDDEN);
        }
      });
    },

    isAuthenticated: function () {
      return UserProfile.then(function (userProfile) {
        if (userProfile.$isAuthenticated()) {
          return Access.OK;
        } else {
          return $q.reject(Access.UNAUTHORIZED);
        }
      });
    }

  };

  return Access;

}])

UserProfile复制当前用户属性,并实施$hasRole$hasAnyRole$isAnonymous$isAuthenticated方法逻辑(加上$refresh方法,稍后解释):

.factory("UserProfile", ["Auth", function (Auth) {

  var userProfile = {};

  var clearUserProfile = function () {
    for (var prop in userProfile) {
      if (userProfile.hasOwnProperty(prop)) {
        delete userProfile[prop];
      }
    }
  };

  var fetchUserProfile = function () {
    return Auth.getProfile().then(function (response) {
      clearUserProfile();
      return angular.extend(userProfile, response.data, {

        $refresh: fetchUserProfile,

        $hasRole: function (role) {
          return userProfile.roles.indexOf(role) >= 0;
        },

        $hasAnyRole: function (roles) {
          return !!userProfile.roles.filter(function (role) {
            return roles.indexOf(role) >= 0;
          }).length;
        },

        $isAnonymous: function () {
          return userProfile.anonymous;
        },

        $isAuthenticated: function () {
          return !userProfile.anonymous;
        }

      });
    });
  };

  return fetchUserProfile();

}])

Auth负责请求服务器,知道用户配置文件(例如链接到附加到请求的访问令牌):

.service("Auth", ["$http", function ($http) {

  this.getProfile = function () {
    return $http.get("api/auth");
  };

}])

在请求GET api/auth时,服务器应该返回这样的JSON对象:

{
  "name": "John Doe", // plus any other user information
  "roles": ["ROLE_ADMIN", "ROLE_USER"], // or any other role (or no role at all, i.e. an empty array)
  "anonymous": false // or true
}

最后,当Access拒绝承诺时,如果使用ui.router$stateChangeError事件将被触发:

.run(["$rootScope", "Access", "$state", "$log", function ($rootScope, Access, $state, $log) {

  $rootScope.$on("$stateChangeError", function (event, toState, toParams, fromState, fromParams, error) {
    switch (error) {

    case Access.UNAUTHORIZED:
      $state.go("signIn");
      break;

    case Access.FORBIDDEN:
      $state.go("forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

如果使用ngRoute,则会触发$routeChangeError事件:

.run(["$rootScope", "Access", "$location", "$log", function ($rootScope, Access, $location, $log) {

  $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) {
    switch (rejection) {

    case Access.UNAUTHORIZED:
      $location.path("/signin");
      break;

    case Access.FORBIDDEN:
      $location.path("/forbidden");
      break;

    default:
      $log.warn("$stateChangeError event catched");
      break;

    }
  });

}])

也可以在控制器中访问用户配置文件:

.state("home", {
  /* ... */
  controller: "HomeController",
  resolve: {
    userProfile: "UserProfile"
  }
})
然后

UserProfile包含服务器在请求GET api/auth时返回的属性:

.controller("HomeController", ["$scope", "userProfile", function ($scope, userProfile) {

  $scope.title = "Hello " + userProfile.name; // "Hello John Doe" in the example

}])
用户登录或注销时需要刷新

UserProfile,以便Access可以使用新的用户配置文件处理路由。您可以重新加载整个页面,也可以致电UserProfile.$refresh()。登录时的示例:

.service("Auth", ["$http", function ($http) {

  /* ... */

  this.signIn = function (credentials) {
    return $http.post("api/auth", credentials).then(function (response) {
      // authentication succeeded, store the response access token somewhere (if any)
    });
  };

}])
.state("signIn", {
  /* ... */
  controller: "SignInController",
  resolve: {
    /* ... */
    userProfile: "UserProfile"
  }
})
.controller("SignInController", ["$scope", "$state", "Auth", "userProfile", function ($scope, $state, Auth, userProfile) {

  $scope.signIn = function () {
    Auth.signIn($scope.credentials).then(function () {
      // user successfully authenticated, refresh UserProfile
      return userProfile.$refresh();
    }).then(function () {
      // UserProfile is refreshed, redirect user somewhere
      $state.go("home");
    });
  };

}])

为各个路线定义自定义行为的最简单方法非常简单:

1)routes.js:为任何所需路线创建新属性(如requireAuth

angular.module('yourApp').config(function($routeProvider) {
    $routeProvider
        .when('/home', {
            templateUrl: 'templates/home.html',
            requireAuth: true // our custom property
        })
        .when('/login', {
            templateUrl: 'templates/login.html',
        })
        .otherwise({
            redirectTo: '/home'
        });
})

2)在未绑定到ng-view内部元素的顶层控制器中(为避免与角度$routeProvider发生冲突),请检查newUrl是否存在拥有requireAuth属性并相应地采取行动

 angular.module('YourApp').controller('YourController', function ($scope, $location, session) {

     // intercept the route change event
     $scope.$on('$routeChangeStart', function (angularEvent, newUrl) {

         // check if the custom property exist
         if (newUrl.requireAuth && !session.user) {

             // user isn’t authenticated
             $location.path("/login");
         }
     });
 });

我几个月前写了一篇关于如何使用Angular设置用户注册和登录功能的帖子,你可以在http://jasonwatmore.com/post/2015/03/10/AngularJS-User-Registration-and-Login-Example.aspx

查看。

我检查用户是否登录了$locationChangeStart事件,这是我的主要app.js显示:

(function () {
    'use strict';
 
    angular
        .module('app', ['ngRoute', 'ngCookies'])
        .config(config)
        .run(run);
 
    config.$inject = ['$routeProvider', '$locationProvider'];
    function config($routeProvider, $locationProvider) {
        $routeProvider
            .when('/', {
                controller: 'HomeController',
                templateUrl: 'home/home.view.html',
                controllerAs: 'vm'
            })
 
            .when('/login', {
                controller: 'LoginController',
                templateUrl: 'login/login.view.html',
                controllerAs: 'vm'
            })
 
            .when('/register', {
                controller: 'RegisterController',
                templateUrl: 'register/register.view.html',
                controllerAs: 'vm'
            })
 
            .otherwise({ redirectTo: '/login' });
    }
 
    run.$inject = ['$rootScope', '$location', '$cookieStore', '$http'];
    function run($rootScope, $location, $cookieStore, $http) {
        // keep user logged in after page refresh
        $rootScope.globals = $cookieStore.get('globals') || {};
        if ($rootScope.globals.currentUser) {
            $http.defaults.headers.common['Authorization'] = 'Basic ' + $rootScope.globals.currentUser.authdata; // jshint ignore:line
        }
 
        $rootScope.$on('$locationChangeStart', function (event, next, current) {
            // redirect to login page if not logged in and trying to access a restricted page
            var restrictedPage = $.inArray($location.path(), ['/login', '/register']) === -1;
            var loggedIn = $rootScope.globals.currentUser;
            if (restrictedPage && !loggedIn) {
                $location.path('/login');
            }
        });
    }
 
})();

您可以使用resolve

angular.module('app',[])
.config(function($routeProvider)
{
    $routeProvider
    .when('/', {
        templateUrl  : 'app/views/login.html',
        controller   : 'YourController',
        controllerAs : 'Your',
        resolve: {
            factory : checkLoginRedirect
        }
    })
}

并且,决心的功能:

function checkLoginRedirect($location){

    var user = firebase.auth().currentUser;

    if (user) {
        // User is signed in.
        if ($location.path() == "/"){
            $location.path('dash'); 
        }

        return true;
    }else{
        // No user is signed in.
        $location.path('/');
        return false;
    }   
}

Firebase还有一个方法可以帮助您安装观察者,我建议将其安装在.run内:

.run(function(){

    firebase.auth().onAuthStateChanged(function(user) {
        if (user) {
            console.log('User is signed in.');
        } else {
            console.log('No user is signed in.');
        }
    });

例如,一个应用程序有两个名为ap和auc的用户。我正在向每个路由传递一个额外的属性,并根据$ routeChangeStart中的数据处理路由。

试试这个:

angular.module("app").config(['$routeProvider',
function ($routeProvider) {

    $routeProvider.
            when('/ap', {
                templateUrl: 'template1.html',
                controller: 'template1',
                isAp: 'ap',
            }).
            when('/auc', {
                templateUrl: 'template2.html',
                controller: 'template2',
                isAp: 'common',
            }).
            when('/ic', {
                templateUrl: 'template3.html',
                controller: 'template3',
                isAp: 'auc',
            }).
            when('/mup', {
                templateUrl: 'template4.html',
                controller: 'template4',
                isAp: 'ap',
            }).

            when('/mnu', {
                templateUrl: 'template5.html',
                controller: 'template5',
                isAp: 'common',
            }).                               
            otherwise({
                redirectTo: '/ap',
            });
   }]);

app.js:

所有人都提出了很大的解决方案,为什么你担心客户端的会话。 我的意思是当状态/网址发生变化时,我想你正在进行ajax调用来加载温和的数据。

Note :- To Save user's data you may use `resolve` feature of `ui-router`.
 Check cookie if it exist load template , if even cookies doesn't exist than 
there is no chance of logged in , simply redirect to login template/page.

现在服务器使用任何api返回ajax数据。现在重点发挥作用,根据用户登录状态使用服务器返回标准返回类型。检查这些返回代码并在控制器中处理您的请求。 注意: - 对于本机不需要ajax调用的控制器,您可以像服务器server.location/api/checkSession.php一样向服务器调用空白请求,这是 checkSession.php

<?php/ANY_LANGUAGE
session_start();//You may use your language specific function if required
if(isset($_SESSION["logged_in"])){
set_header("200 OK");//this is not right syntax , it is just to hint
}
else{
set_header("-1 NOT LOGGED_IN");//you may set any code but compare that same       
//code on client side to check if user is logged in or not.
}
//thanks.....

在控制器内的客户端或通过任何服务,如其他答案中所示

    $http.get(dataUrl)
    .success(function (data){
        $scope.templateData = data;
    })
    .error(function (error, status){
        $scope.data.error = { message: error, status: status};
        console.log($scope.data.error.status);
if(status == CODE_CONFIGURED_ON_SERVER_SIDE_FOR_NON_LOGGED_IN){
//redirect to login
  });

您应该检查两个主要站点中的用户身份验证。

  • 当用户更改状态时,使用'$routeChangeStart'回调
  • 进行检查
  • 当使用拦截器从angular发送$ http请求时。
