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。

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() {
var userAgent = navigator.userAgent.toLowerCase();
if (userAgent.indexOf("msie") != -1) {
document.execCommand("ClearAuthenticationCache", false);
}
xhr_objectCarte = null;
if(window.XMLHttpRequest)
xhr_object = new XMLHttpRequest();
else if(window.ActiveXObject)
xhr_object = new ActiveXObject("Microsoft.XMLHTTP");
else
alert ("Your browser doesn't support XMLHTTPREQUEST");
xhr_object.open ('GET', 'http://yourserver.com/rep/index.php', false, 'username', 'password');
xhr_object.send ("");
xhr_object = null;
document.location = 'http://yourserver.com';
return false;

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);
?>

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);*/
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.

但它只会把你重定向到新的位置。没有注销。
下面是一个使用jQuery的非常简单的Javascript示例:
function logout(to_url) {
var out = window.location.href.replace(/:\/\//, '://log:out@');
jQuery.get(out).error(function() {
window.location = to_url;
});
}
此登录用户退出而不再次显示浏览器登录框，然后将其重定向到注销页面
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。
为了记录，有一个新的HTTP响应头叫做Clear-Site-Data。如果你的服务器回复包含一个Clear-Site-Data: "cookies"头，那么身份验证凭证(不仅仅是cookies)应该被删除。我在Chrome 77上测试了它，但控制台显示了这个警告:
Clear-Site-Data header on 'https://localhost:9443/clear': Cleared data types:
"cookies". Clearing channel IDs and HTTP authentication cache is currently not
supported, as it breaks active network connections.
并且认证凭证没有被删除，所以这不能(目前)实现基本的认证注销，但也许将来会。没有在其他浏览器上测试。
