如何注销用户从网站使用基本身份验证?

是否有可能注销用户从一个网站，如果他是使用基本身份验证?

杀死会话是不够的，因为一旦用户通过身份验证，每个请求都包含登录信息，因此用户下次使用相同的凭据访问站点时将自动登录。

目前唯一的解决方案是关闭浏览器，但从可用性的角度来看，这是不可接受的。

让用户点击指向https://log:out@example.com/的链接。这将用无效的凭证覆盖现有的凭证;注销它们。

这是通过在URL中发送新的凭证来实现的。在本例中，user="log" password="out"。

这适用于IE/Netscape/Chrome浏览器:

      function ClearAuthentication(LogOffPage) 
  {
     var IsInternetExplorer = false;    

     try
     {
         var agt=navigator.userAgent.toLowerCase();
         if (agt.indexOf("msie") != -1) { IsInternetExplorer = true; }
     }
     catch(e)
     {
         IsInternetExplorer = false;    
     };

     if (IsInternetExplorer) 
     {
        // Logoff Internet Explorer
        document.execCommand("ClearAuthenticationCache");
        window.location = LogOffPage;
     }
     else 
     {
        // Logoff every other browsers
    $.ajax({
         username: 'unknown',
         password: 'WrongPassword',
             url: './cgi-bin/PrimoCgi',
         type: 'GET',
         beforeSend: function(xhr)
                 {
            xhr.setRequestHeader("Authorization", "Basic AAAAAAAAAAAAAAAAAAA=");
         },

                 error: function(err)
                 {
                    window.location = LogOffPage;
             }
    });
     }
  }


  $(document).ready(function () 
  {
      $('#Btn1').click(function () 
      {
         // Call Clear Authentication 
         ClearAuthentication("force_logout.html"); 
      });
  });

在地址栏中输入chrome://restart, chrome和所有在后台运行的应用程序将重新启动，Auth密码缓存将被清除。

这是我的注销是如何使用形式工作:

创建基本认证用户注销密码注销创建目录logout/和添加.htaccess:行'要求用户注销'

RewriteEngine On
AuthType Basic
AuthName "Login"
AuthUserFile /mypath/.htpasswd
require user logout

添加注销按钮，网站的形式如下:

<form action="https://logout:logout@example.com/logout/" method="post">
   <button type="submit">Logout</button>
</form>

Logout /index.php可以是这样的:

<?php
echo "LOGOUT SUCCESS";
header( "refresh:2; url=https://example.com" );
?>

5.9.2022确认支持chrome、edge和三星android网络浏览器

    function logout(secUrl, redirUrl) {
        if (bowser.msie) {
            document.execCommand('ClearAuthenticationCache', 'false');
        } else if (bowser.gecko) {
            $.ajax({
                async: false,
                url: secUrl,
                type: 'GET',
                username: 'logout'
            });
        } else if (bowser.webkit) {
            var xmlhttp = new XMLHttpRequest();
            xmlhttp.open("GET", secUrl, true);
            xmlhttp.setRequestHeader("Authorization", "Basic logout");
            xmlhttp.send();
        } else {
            alert("Logging out automatically is unsupported for " + bowser.name
                + "\nYou must close the browser to log out.");
        }
        setTimeout(function () {
            window.location.href = redirUrl;
        }, 200);
    }

我试着以以下方式使用上述方法。

?php
    ob_start();
    session_start();
    require_once 'dbconnect.php';

    // if session is not set this will redirect to login page
    if( !isset($_SESSION['user']) ) {
        header("Location: index.php");
        exit;
    }
    // select loggedin users detail
    $res=mysql_query("SELECT * FROM users WHERE userId=".$_SESSION['user']);
    $userRow=mysql_fetch_array($res);
?>
<!DOCTYPE html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

function logout(secUrl, redirUrl) {
alert(redirUrl);
    if (bowser.msie) {
        document.execCommand('ClearAuthenticationCache', 'false');
    } else if (bowser.gecko) {
        $.ajax({
            async: false,
            url: secUrl,
            type: 'GET',
            username: 'logout'
        });
    } else if (bowser.webkit) {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.open("GET", secUrl, true);
        xmlhttp.setRequestHeader("Authorization", "Basic logout");
        xmlhttp.send();
    } else {
        alert("Logging out automatically is unsupported for " + bowser.name
            + "\nYou must close the browser to log out.");
    }
    window.location.assign(redirUrl);
    /*setTimeout(function () {
        window.location.href = redirUrl;
    }, 200);*/
}

       alert("f1 called");

但它只会把你重定向到新的位置。没有注销。

 function logout(url){
    var str = url.replace("http://", "http://" + new Date().getTime() + "@");
    var xmlhttp;
    if (window.XMLHttpRequest) xmlhttp=new XMLHttpRequest();
    else xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
