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

index.php

<?php //index.php 应用程序页面 header('Content-Type:text/html; charset=utf-8'); $sso_address = 'http://localhost/default/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{$_COOKIE['sign']} <a href=\"login.php?logout\">退出</a>"); }else{     echo '您还未登录 <a href="'.$sso_address.'?callback='.$callback_address.'">点此登录</a>'; } ?><iframe src="<?php echo $sso_address ?>?callback=<?php echo $callback_address ?>" frameborder="0"  width="0" height="0"></iframe>

    <?php     //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'])){     ?>     <form method="post">     <p>用户名：<input type="text" name="username" /></p>     <p>密  码：<input type="password" name="password" /></p>     <input type="hidden" name="callback" value="<?php echo $_GET['callback']; ?>" />     <input type="submit" value="登录" />     </form>     <?php     }else{         $query = http_build_query($_COOKIE);         echo "系统检测到您已登录 {$_COOKIE['sign']} <a href=\"{$_GET['callback']}?{$query}\">授权</a> <a href=\"?logout\">退出</a>";     }     ?>

callback.php

<?php //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

<?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; } ?><html><script type="text/javascript">top.location.href="<?php echo $callback; ?>";</script></html>
