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" );
?>

我刚刚在Chrome(79)、Firefox(71)和Edge(44)上测试了以下程序，效果良好。它应用上面提到的脚本解决方案。
只需添加一个“注销”链接，点击返回以下html
<div>You have been logged out. Redirecting to home...</div>
<script>
var XHR = new XMLHttpRequest();
XHR.open("GET", "/Home/MyProtectedPage", true, "no user", "no password");
XHR.send();
setTimeout(function () {
window.location.href = "/";
}, 3000);
</script>
我为现代Chrome版本更新了mthoring的解决方案:
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 || bowser.chrome) {
var xmlhttp = new XMLHttpRequest();
xmlhttp.open(\"GET\", secUrl, true);
xmlhttp.setRequestHeader(\"Authorization\", \"Basic logout\");\
xmlhttp.send();
} else {
// http://stackoverflow.com/questions/5957822/how-to-clear-basic-authentication-details-in-chrome
redirUrl = url.replace('http://', 'http://' + new Date().getTime() + '@');
}
setTimeout(function () {
window.location.href = redirUrl;
}, 200);
}
添加到你的应用程序:
@app.route('/logout')
def logout():
return ('Logout', 401, {'WWW-Authenticate': 'Basic realm="Login required"'})
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>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Welcome - <?php echo $userRow['userEmail']; ?></title>
<link rel="stylesheet" href="assets/css/bootstrap.min.css" type="text/css" />
<link rel="stylesheet" href="style.css" type="text/css" />
<script src="assets/js/bowser.min.js"></script>
<script>
//function logout(secUrl, redirUrl)
//bowser = require('bowser');
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.
}
</script>

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");
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4) location.reload();
}
xmlhttp.open("GET",str,true);
xmlhttp.setRequestHeader("Authorization","Basic xxxxxxxxxx")
xmlhttp.send();
return false;
}
