php sso单点登录实现代码
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:
<?php //index.php 应用程序页面 header( 'Content-Type:text/html; charset=utf-8' ); $sso_address = 'http://2spaoku测试数据/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 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>" ; } ?> <?php //callback.php 回调页面用来设置跨域COOKIE header( 'Content-Type:text/html; charset=utf-8' ); if ( empty empty ( $_GET )){ exit ( '您还未登录' ); } else { foreach ( $_GET as $key => $val ){ setcookie( $key , $val ,0, '' ); } header( "location:index.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 { //开源代码phpfensi测试数据 exit ; } ?> <html><script type= "text/javascript" >top.location.href= "<?php echo $callback; ?>" ;</script></html>查看更多关于php sso单点登录实现代码 - php高级应用的详细内容...
