《PHP應(yīng)用：php的sso單點(diǎn)登錄實(shí)現(xiàn)方法》要點(diǎn)：
本文介紹了PHP應(yīng)用：php的sso單點(diǎn)登錄實(shí)現(xiàn)方法，希望對您有用。如果有疑問，可以聯(lián)系我們。
PHP編程本文實(shí)例講述了php的sso單點(diǎn)登錄實(shí)現(xiàn)辦法.分享給大家供大家參考.具體分析如下：
PHP編程這里詳細(xì)講到了幾點(diǎn)：
1、點(diǎn)擊登錄跳轉(zhuǎn)到SSO登錄頁面并帶上當(dāng)前應(yīng)用的callback地址
2、登錄成功后生成COOKIE并將COOKIE傳給callback地址
3、callback地址接收SSO的COOKIE并設(shè)置在當(dāng)前域下再跳回到應(yīng)用1即完成登錄
4、再在應(yīng)用程序需要登錄的地方嵌入一個(gè)iframe用來實(shí)時(shí)檢測登錄狀態(tài),代碼如下:
index.php 應(yīng)用程序頁面:
代碼如下:
<?php?
header('Content-Type:text/html; charset=utf-8');?
$sso_address = 'http://XXXX.com/sso/login.php'; //你SSO所在的域名?
$callback_address = 'http://'.$_SERVER['HTTP_HOST']?
??????????????????? .str_replace('index.php','',$_SERVER['SCRIPT_NAME'])?
??????????????????? .'callback.php'; //callback地址用于回調(diào)設(shè)置cookie
?
if(isset($_COOKIE['sign'])){?
??? exit("歡迎您{$_COOKIE['sign']} <a href="login.php?logout">退出</a>");?
}else{?
??? echo '您還未登錄 <a href="'.$sso_address.'?callback='.$callback_address.'">點(diǎn)此登錄</a>';?
}?
?>
<iframe src="<?php echo $sso_address ?>?callback=<?php echo $callback_address ?>" frameborder="0"? width="0" height="0"></iframe>
login.php SSO登錄頁面：
代碼如下:
<?php?
header('Content-Type:text/html; charset=utf-8');?
if(isset($_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(emptyempty($_COOKIE['sign'])){?
?>
?
<form method="post">?
<p>用戶名：<input type="text" name="username" /></p>?
<p>密? 碼：<input type="password" name="password" /></p>?
<input type="hidden" name="callback" value="<?php echo $_GET['callback']; ?>" />?
<input type="submit" value="登錄" />?
</form>
?
?
<?php?
}else{?
??? $query = http_build_query($_COOKIE);?
??? echo "系統(tǒng)檢測到您已登錄 {$_COOKIE['sign']} <a href="{$_GET['callback']}?{$query}">授權(quán)</a> <a href="?logout">退出</a>";?
}?
?>
callback.php 回調(diào)頁面用來設(shè)置跨域COOKIE：
代碼如下:
<?php?
header('Content-Type:text/html; charset=utf-8');?
if(emptyempty($_GET)){?
??? exit('您還未登錄');?
}else{?
??? foreach($_GET as $key=>$val){?
??????? setcookie($key,$val,0,'');?
??? }?
??? header("location:index.php");?
}
?>
connect.php 用來檢測登錄狀態(tài)的頁面,內(nèi)嵌在頁面的iframe中：
代碼如下:
<?php
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>
