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


//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'])){
?>


}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;
}
?>
