我正在开发 AngularJs 应用程序，后端是在 Ruby on Rails 中开发的。我们没有使用 Devise gem 进行用户身份验证。整个用户认证过程是用 AngularJs 编写的。现在我想使用 AngularJs 向我的应用程序添加“保持登录”功能。
题:
如何在 AngularJs 中为我的应用程序实现“保持登录状态”功能？
我将 angularJs 用于 View 和 Controller ，并且模型是用 Ruby on Rails 编写的。
我在下面附上了我的 session-controller.js 和 View 文件。
session-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, '');
createCookie("user", data.user.id, '');
createCookie("name", data.user.name, '');
if (data.user.temp_password == true && data.user.login_count == 1) {
$location.path('/changepassword');
} else {
if (data.user.role == "SmartonAdmin") {
$location.path('/api/users');
flash.info = ($rootScope.config && $rootScope.config.login_message) ? $rootScope.config.login_message : "Logged in successfully";
goToTop();
if (data.user.login_count == 1) {
$('#intro-video').modal('show');
}
} else {
$location.path('/student_dashboard');
flash.info = ($rootScope.config && $rootScope.config.login_message) ? $rootScope.config.login_message : "Logged in successfully";
goToTop();
if (data.user.login_count == 1) {
$('#intro-video').modal('show');
}
}
}
}).error(function(data, status) {
flash.error = data.errors;
goToTop();
});
}
};
$scope.validations = function() {
$('#signInForm').validate({
rules : {
email : {
required : true,
email : true
},
password : {
required : true,
}
},
messages : {
email : {
required : "Email can't be blank.",
email : "Email must be in the format of name@domain.com.",
remote : "Email already exists."
},
password : {
required : "Password can't be blank.",
minlength : "Password should have minimum of 8 characters.",
maxlength : "Password should not exceed more than 15 characters."
}
},
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() {
if (!this.value) {
$(".errormsg").css("display", "none");
}
});
$scope.showForgotPasswordForm = function() {
$('#signInForm').css('opacity', '0.5');
$('#forgotPassForm').show();
};
$scope.remember = false;
if ($remember('email') && $remember('password') ) {
$scope.remember = true;
$scope.email = $remember('email');
$scope.password = $remember('password');
}
$scope.rememberMe = function() {
if ($scope.remember) {
$remember('email', $scope.email);
$remember('password', $scope.password);
} 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 AngularJs 实现？
最佳答案
您可以将此类选项保留在用户的本地存储中，但要小心放置在那里的内容，它应该存储访问 token 或加密数据，避免以纯文本形式存储用户凭据，请参阅此链接以了解如何使用带有 Angular 的本地存储:
