使用Angularjs在PHP上维护会话

Question

代码运行良好，但是当我刷新页面服务PHP时，我不知道如何但已经登录。虽然我之前登录过。

app.js

web_app.controller("form_dang_nhap_gio_hang", function($scope, $http){ 
$http({ 
    method: 'GET', 
    url: 'services/api_kiem_tra_dang_nhap.php' 
}).success(function(data, status, headers, config){ 
     $scope.thong_tin_dang_nhap = data; 
}).error(function(data, status, headers, config){ 
     alert("lỗi không gửi được!"); 
}); 

$scope.btn_dang_nhap_tai_khoan = function(){ 
    data_chuyen_di = '{ "data" : {"ten_dang_nhap":"'+$scope.ten_dang_nhap+'","mat_khau":"'+$scope.mat_khau+'"}}'; 
    //alert(data_chuyen_di); 
    $http({ 
     url: 'services/api_kiem_tra_dang_nhap.php', 
     method: "POST", 
     data: data_chuyen_di, 
     headers: {'Content-Type': 'application/x-www-form-urlencoded'} 
    }).success(function (data, status, headers, config) { 
     //alert(data); 
     if(data.thong_bao_loi != "") 
     { 
      alert(data.thong_bao_loi); 
     } 
     else 
     { 
      $scope.thong_tin_dang_nhap = data; 
      $("#modal-id").modal('hide'); 
     } 
     //$scope.persons = data; // assign $scope.persons here as promise is resolved here 
    }).error(function (data, status, headers, config) { 
     alert("lỗi không gửi được!"); 
    }); 
} 

}）;

PHP服务，当它获得发布数据时添加会话，如果它之前没有会话并且登录信息是正确的话。如果它已经登录，那么它将返回登录信息。

$json = file_get_contents('php://input'); 
$doi_tuong_truyen_vao = json_decode($json); 
//print_r($doi_tuong_truyen_vao); 
if($doi_tuong_truyen_vao) 
{ 

    include_once("database.php"); 

    $db = new database(); 

    $lenh_sql = "select * from sqa_nguoi_dung WHERE tai_khoan = '" . $doi_tuong_truyen_vao->data->ten_dang_nhap . "'"; 
    $db->setQuery($lenh_sql); 
    $tt_nguoi_dung = $db->loadRow(); 
    //print_r($tt_nguoi_dung); 
    if($tt_nguoi_dung) 
    { 
     if($tt_nguoi_dung->mat_khau == $doi_tuong_truyen_vao->data->mat_khau) 
     { 
      //print_r($tt_nguoi_dung); 
      $_SESSION["nguoi_dung"] = $tt_nguoi_dung; 
      $tt_nguoi_dung->thong_bao_loi = ""; 
      echo json_encode($tt_nguoi_dung); 
     } 
     else 
     { 
      echo '{"thong_bao_loi":"Mật khẩu không chính xác!"}'; 
     } 
    } 
    else 
    { 
     echo '{"thong_bao_loi":"Tài khoản không tồn tại!"}'; 
    } 
} 
else 
{ 
    if($_SESSION["nguoi_dung"]) 
    { 
     $chuoi = json_encode($_SESSION["nguoi_dung"]); 
     echo $chuoi; 
    } 
    else 
    { 
     $chuoi = ""; 
    } 
}

任何想法??

当你编写angularjs时，你只是编码客户端......而php是服务器端语言......所以当你从客户端登录时，你应该在服务器端做一个sessionvariable ......并且将其发送到您的客户端以保存为html5功能的本地存储或会话存储。

现在，每当任何请求从客户端发送到服务器，存储在该sessionstorage值必须被附加到请求..和检查，以服务器侧..

在情况下，它不提供在服务器端，它应该返回403UNAUTHORIZED ACCESS状态码......它将被你的拦截器捕获，并且你将能够正确地维护会话。

你可以从这个链接的的localStorage和sessionStorage的.. http://ngmodules.org/modules/ngStorage
