PHP怎么实现域名授权
PHP实现域名授权的方法:首先获取不带端口号的域名前缀;然后获取服务端授权文件校验;接着在服务端代码文件中通过“$_GET”获取域名;最后授权域名列表并检验结果即可。
PHP怎么实现域名授权?
01. 在线校验域名授权的方法:
客户端代码:
<?php //获取不带端口号的域名前缀 $servername = trim($_SERVER['SERVER_NAME']); //获取服务端授权文件校验 $verifyurl = file_get_contents('http://www.toyean.com/zb_users/upload/copyright.php?domain='.$servername); if(!empty($verifyurl)){ echo "已授权!"; //授权成功 }else{ die("未授权!"); //授权失败 } ?>
服务端代码:
<?php //获取域名 $domain = $_GET['domain']; //授权域名列表 $Array = array('127.0.0.1','localhost'); //校验结果 echo in_array($domain, $Array) ? 'yes' : ''; ?>
域名授权代码可封装进函数,或者进行加密,对于常用的PHP加密形式,都有其破解的方法,比如ZendGuard、ionCube等,如果授权的域名较多,可以在项目中增加域名字段,将域名写入数据库再进行读取和校验,此方法我们已发布成独立的插件,详见:ZBlogPHP域名授权插件-AllowURL, 通过插件可以将域名等信息添加到数据库中进行校验。
02. 独立校验域名授权的方法:
<?php function allow_domain(){ $is_allow=false; //获取不带端口号的域名前缀 $servername=trim($_SERVER['SERVER_NAME']); //授权域名列表 $Array=array("localhost","127.0.0.1"); //遍历数组 foreach($Array as $value){ $value=trim($value); $domain=explode($value,$servername); if(count($domain)>1){ $is_allow=true; break; } } if(!$is_allow){ die("域名未授权!"); //授权失败 }else{ echo "域名已授权!"; //授权成功 } } allow_domain(); ?>
域名授权的目的在于保护知识产权,鼓励开发者能够发布更多优秀的作品,推动整个网络社会的文化发展与科技进步,有着十分重要的意义。
