how to use session in angularjs

本文关键字：session angularjs      更新时间：2023-09-26

我正在创建一个web应用程序，我想在其中通过Angularjs 将用户ID和角色存储在session中

这是我的Angularjs文件

$http.get('/login.asmx/loginuser', {
                params: {
                    log: $scope.log,
                    pm: $scope.pm,
                    password: $scope.password
                }
            })
            .then(function (response) {
                {
                    $scope.suc = response.data;
                    console.log(response.data);
                    if (response.data == 'success') {
                        console.log('success');
                        $window.location.href = "../welcomepage/welcometable";
                    }
                    else
                    {
                        console.log('nosuccess');
                        $window.location.href = "../Login/Index";
                    }
                }
            })

我需要在会话中存储$scope.pm和$scope.log，并希望在我的欢迎页面上使用它们

如何在angularjs中存储和使用会话？

您可以使用会话存储或本地存储，以下是会话存储的示例。

在堆栈溢出的情况下，会话存储或本地存储将不起作用所以参考给定的链接。

window.addCart = function($scope, $http, $window, $document){
  
    var getValue = function(){
        return $window.sessionStorage.length;
    }
      
    var getData = function(){
      var json = [];
      $.each($window.sessionStorage, function(i, v){
        json.push(angular.fromJson(v));
      });
      return json;
    }
      
    $scope.images = getData();
    $scope.count = getValue();
  
    $scope.addItem = function(id){
        var image = document.getElementById('img'+id);
        json = {
          id: id,
          img: image.src
        }
        $window.sessionStorage.setItem(id, JSON.stringify(json));
        $scope.count = getValue();
        $scope.images = getData();
    }
    
    $scope.removeItem = function(id){
      $window.sessionStorage.removeItem(id);
      $document.
      $scope.count = getValue();
      $scope.images = getData();
      alert('Removed with Success!');
    }
}

 angular.module('cookieStoreExample', ['ngCookies'])
  .controller('ExampleController', ['$cookieStore', function($cookieStore) {
     // Put cookie
  $cookieStore.put('myFavorite','oatmeal');
  // Get cookie
  var favoriteCookie = $cookieStore.get('myFavorite');
  // Removing a cookie
  $cookieStore.remove('myFavorite');
}]);
