登錄/注銷會話問題

[英]Problems with Login/Logout Session

我正在嘗試創建一個登錄系統,該系統將根據登錄類型顯示不同的頁面。 (即以管理員身份或其他各種角色登錄)

它由三個文件組成:

Login.php-在此提交各種表單,並根據表單值名稱將會話變量設置為正確的級別(例如admin等)

Logout.php-取消設置前面提到的變量。

Dashboard.php-檢查是否設置了變量,如果已設置,則加載相關事件信息,如果未設置,則發送回index.php

請在下面的代碼中找到:

Login.php

<?php
session_start();
if (isset($_POST['uname_driver']))
{
    $username = $_POST['uname_driver'];
    $hpassword = password_hash($_POST['hpass_driver'], PASSWORD_DEFAULT);
    // Check here for login details within server
    $_SESSION['loggedIn'] = "driver";
    header("Location: dashboard.php");
}
if (isset($_POST['uname_restaurant']))
{
    $username = $_POST['uname_restaurant'];
    $hpassword = password_hash($_POST['hpass_restaurant'], PASSWORD_DEFAULT);
    // Check here for login details within server
    $_SESSION['loggedIn'] = "restaurant";
    header("Location: dashboard.php");
}
if (isset($_POST['uname_admin']))
{
    $username = $_POST['uname_admin'];
    $hpassword = password_hash($_POST['hpass_admin'], PASSWORD_DEFAULT);
    // Check here for login details within server
    $_SESSION['loggedIn'] = "admin";
    header("Location: dashboard.php");
}

Logout.php- 編輯以反映Juned的答案,該答案解決了問題的一部分

<?php 
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();


header("Location: index.php");

Dashboard.php

<?php
session_start();
include("header.php");
if (isset($_SESSION['loggedIn']))
{
    switch ($_SESSION['loggedIn'])
    {
        case "admin":
            include("admin_dashboard.php");
            break;
        case "driver":
            include("driver_dashboard.php");
            break;
        case "restaurant":
            include("restaurant_dashboard.php");
            break;
    }
}
else
{
    header("Location: index.php");
}
?>

在出現工作日志精絕,直到我嘗試再次注銷 ,注銷與某個按鈕的儀表板和一個jQuery后,像這樣一個onclick事件來實現:

$('#logoutOfDashboard').click(function(e)
{
    e.preventDefault();
    var reallyLogout=confirm("Do you really want to log out?");
    if(reallyLogout)
    {
        $.post('logout.php', {})
        .done(function(data)
        { 
            window.location.replace("/");
        })
    }
});

再次,這似乎可行,但是,如果我在URL欄中手動輸入/dashboard.php,則會按預期將我踢回到index.php。 現在,無論何時提交登錄表單,都應該重新創建會話變量,dashboard.php都會不斷地跳回索引,就像它不在那兒一樣,在此會話期間我將無法登錄。 幾乎就像會話變量在未設置時進行緩存,並且永遠無法重新設置

我嘗試添加各種無緩存標頭信息,例如:

header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

但這似乎沒有效果。 任何幫助或有識之士將不勝感激。

我試圖使用您的代碼在計算機上創建本地測試頁。 它似乎工作正常。 如果您正在處理會話和Cookie,並且進行了大量的測試或調試,有時會弄亂瀏覽器,那么我可能會提出什么建議。 嘗試清除您的緩存/ cookie。 我打算將其放在評論部分,但我沒有足夠的聲譽:)但是,如果這沒有幫助,請告訴我,並將其刪除。

您需要銷毀會話,因此,不僅要取消$ _SESSION [“ loggedin”]的設置,還需要通過占用會話cookie來完全銷毀會話。 PHP具有內置函數可以為您執行此操作:session_destroy();

請參閱: http//php.net/manual/en/function.session-destroy.php

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

據我了解,這里發生的主要問題是維護整個系統的會話。

我已經為登錄系統編寫了一個簡單的代碼,相信有助於理解這一點。 在研究Aphire的代碼之前,我想提到沒有必要在代碼中使用Ajax,因為最后有頁面刷新,因此如果您直接將用戶重定向到logout.php上將是一個很好的選擇。

無論如何,請參見下面給出的代碼,這肯定有助於理解登錄系統中的會話使用。

login.php

<?php
$name = $_GET['name'];
session_start();

if(isset($_SESSION['loggedIn']))
{
    header("Location: dashboard.php");
} else {
    if (isset($name))
    {
            $_SESSION['loggedIn'] = $name;
            header("Location: dashboard.php");
    } else {
        echo "Please provide correct input";
    }
}
?>

logout.php

<?php 
// Initialize the session.
session_start();

// Finally, destroy the session.
session_destroy();


header("Location: login.php");
?>

dashboard.php

<?php
session_start();

if (isset($_SESSION['loggedIn']))
{
    switch ($_SESSION['loggedIn'])
    {
        case "admin":
            echo "admin";
            break;
        case "driver":
            echo "driver";
            break;
        case "restaurant":
            echo "restaurant";
            break;
    default:
        header("Location: login.php");
        session_destroy();
    }
}
else
{
    header("Location: login.php");
}
?>

<a href="logout.php">Logout</a>

代替使用window.location.replace() ,嘗試使用window.location.href='/'

您是否嘗試過保留會話ID,而只是刪除會話數據? 我想沒有刪除會話ID的意義。

我正在談論從logout.php刪除這段代碼:

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();

因此, logout.php現在看起來像:

<?php 
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

header("Location: index.php");

這應該足以“注銷”用戶。

我用您的代碼片段創建了一個小版本,並在我的本地主機上進行了嘗試,就像Roljhon一樣

一切似乎都正常。 我認為其他代碼或您的服務器配置可能有問題。 我不能說。

如果有幫助,請使用以下代碼進行測試:

loginForm.php

<?php
Header("Cache-Control: max-age=3000, must-revalidate");
//include("header.php");
?>
<div class="container">
  <form class="form-signin" action="login.php" method="post">
    <input type="email" name = "uname_restaurant" id="inputEmail" class="form-control" placeholder="Email" required autofocus>
    <input type="password" name = "hpass_restaurant" id="inputPassword" class="form-control" placeholder="Password" required>
    <button class="btn btn-lg btn-success btn-block" type="submit">Sign in</button>
  </form>
</div>

login.php

<?php
session_start();
if (isset($_POST['uname_restaurant']))
{
    $username = $_POST['uname_restaurant'];
    $hpassword = password_hash($_POST['hpass_restaurant'], PASSWORD_DEFAULT);
    $_SESSION['loggedIn'] = "restaurant";
}
var_dump($_SESSION);
die("Location: dashboard.php");

dashboard.php

<?php
session_start();
//include("header.php");
if (isset($_SESSION['loggedIn']))
{
    switch ($_SESSION['loggedIn'])
    {
        case "admin":
            die("admin_dashboard.php");
            break;
        case "driver":
            die("driver_dashboard.php");
            break;
        case "restaurant":
            die("restaurant_dashboard.php");
            break;
    }
}
else
{
    die("Location: index.php");
}

logout.php

<?php 
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();

die("Location: index.php");
