ruby-on-rails – 如何在AngularJS中实现“保持登录状态”功能

我正在开发AngularJs应用程序,后端是在 Ruby on Rails上开发的.我们还没有使用Devise gem进行用户身份验证.整个用户身份验证过程是用AngularJs编写的.现在我想使用AngularJs为我的应用程序添加“保持登录状态”功能.

题：
?我如何在AngularJs中为我的应用程序实现“保持登录”功能？

我使用angularJs作为视图和控制器,模型是用Ruby on Rails编写的.

我已将下面的session-controller.js与views文件相关联.

会话controller.js

App.controller('SessionsCtrl',function($rootScope,$scope,$http,$location,Facebook,$timeout,flash,$remember) {

    $scope.fbloginContent = "";

    $scope.googleloginContent = "";

    $scope.linkedinloginContent = "";

    $scope.$on('facebook_login',function() {
        $timeout(function() {
            $scope.fbloginContent = Facebook.getfbLoginContent();
            $scope.loginEmail = $scope.fbloginContent.email;
        },2000);
    });

    $scope.$on('google_login',function() {
        $timeout(function() {
            $scope.googleloginContent = helper.getGoogleloginContent();
            $scope.loginEmail = $scope.googleloginContent.email;
        },2000);
    });

    $scope.$on('linkedin_login',function() {
        $timeout(function() {
            $scope.linkedinloginContent = linkedInHelper.linkedinloginContent();
            $scope.loginEmail = $scope.linkedinloginContent['emailAddress'];
        },2000);
    });

    $scope.login = function() {
        if ($('#signInForm').valid()) {
            if ($scope.linkedinloginContent) {
                var param = {
                    "user" : {
                        "email" : $scope.linkedinloginContent['emailAddress'],"password" : $scope.loginPassword
                    }
                };
            } else if ($scope.googleloginContent) {
                var param = {
                    "user" : {
                        "email" : $scope.googleloginContent.email,"password" : $scope.loginPassword
                    }
                };
            } else if ($scope.fbloginContent) {
                var param = {
                    "user" : {
                        "email" : $scope.fbloginContent.email,"password" : $scope.loginPassword
                    }
                };
            } else {
                if ($scope.loginEmail && $scope.loginPassword) {

                    var param = {
                        "user" : {
                            "email" : $scope.loginEmail,"password" : $scope.loginPassword
                        }
                    };
                } else {
                    var param = {
                        "user" : {
                            "email" : $("#signInForm [name=email]").val(),"password" : $("#signInForm [name=password]").val()
                        }
                    };
                }
            }
            $http({
                method : 'post',url : '/api/sessions',data : param
            }).success(function(data,status) {
                createCookie("access_token",data.user.access_token,'');

                if (data.user.temp_password == true && data.user.login_count == 1) {

                            $('#intro-video').modal('show');
                        }
                    }

    };

    $scope.validations = function() {

        $('#signInForm').validate({
            rules : {
                email : {
                    required : true,email : true
                },password : {

                }   
            },errorPlacement : function(error,element) {
                error.insertBefore('.errorMsg1');
            }
        });

    };

    $scope.validations();

    $("#loginemail").keyup(function() {
        if (!this.value) {
            $(".errormsg").css("display","none");
        }
        if (!(/^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+.[a-zA-Z.]{2,5}$/i.test(this.value))) {
            $(".errormsg").css("display","none");
        }
    });

    $("#loginpassword").keyup(function() {

            } else {
                $remember('email','');
                $remember('password','');
            }
        };

});

将文件视为模板(AngularJs)：

<input type="checkbox" name="remember" class="signup-footage terms-condition " data-ng-   click="rememberMe()" data-ng-model="remember"> Remember Me

我想要的是如果用户点击“记住我”复选框,那么下次用户确实需要登录系统.如何使用AngualarJs实现？
