php sso单点登录实现代码_PHP教程

下面详细讲到了几点。1、点击登录跳转到SSO登录页面并带上当前应用的callback地址2、登录成功后生成COOKIE并将COOKIE传给callback地址3、callback地址接收SSO的COOKIE并设置在当前域下再跳回到应用1即完成登录4、再在应用程序需要登录的地方嵌入一个iframe用来实时检测登录状态

代码如下

复制代码

//index.php 应用程序页面 header('Content-Type:text/html; charset=utf-8'); $sso_address = 'http://2spaoku.com/sso/login.php'; //你SSO所在的域名 $callback_address = 'http://'.$_SERVER['HTTP_HOST'] .str_replace('index.php','',$_SERVER['SCRIPT_NAME']) .'callback.php'; //callback地址用于回调设置cookie if(isset($_COOKIE['sign'])){ exit("欢迎您{$_COOKIE['sign']} 退出"); }else{ echo '您还未登录 点此登录'; } ?> //login.php SSO登录页面 header('Content-Type:text/html; charset=utf-8'); if(isset($_GET['logout'])){ setcookie('sign','',-300); unset($_GET['logout']); header('location:index.php'); } if(isset($_POST['username']) && isset($_POST['password'])){ setcookie('sign',$_POST['username'],0,''); header("location:".$_POST['callback']."?sign={$_POST['username']}"); } if(empty($_COOKIE['sign'])){ ?> 用户名： 密 码： }else{ $query = http_build_query($_COOKIE); echo "系统检测到您已登录 {$_COOKIE['sign']} 授权 退出"; } ?> //callback.php 回调页面用来设置跨域COOKIE header('Content-Type:text/html; charset=utf-8'); if(empty($_GET)){ exit('您还未登录'); }else{ foreach($_GET as $key=>$val){ setcookie($key,$val,0,''); } header("location:index.php"); } ?> //connect.php 用来检测登录状态的页面，内嵌在页面的iframe中 header('Content-Type:text/html; charset=utf-8'); if(isset($_COOKIE['sign'])){ $callback = urldecode($_GET['callback']);unset($_GET['callback']); $query = http_build_query($_COOKIE); $callback = $callback."?{$query}"; }else{ exit; } ?>
