这里分析了php的简单防盗链实现方法。分享飞大家供大家参考。具体如下:
index.php页面如下:
<html> <head> <meta http-equiv="Content-Language" content="en" /> <meta name="GENERATOR" content="PHPEclipse 1.0" /> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>防盗链</title> </head> <body> <form action="check.php" method="post"> 提交信息:<input type="text" name="name" value=""/> <input type="submit" name="submit" value="提交"/> </form> </body> </html>
check.php页面如下:
$urlar=parse_url($_SERVER['HTTP_REFERER']); print("<pre>"); print_r($urlar); print_r($_SERVER['HTTP_REFERER']); if($urlar['host']!="localhost"){//此处可替换成当前使用的域名 echo "验证错误!"; echo "<script>alert('连接失败');location.href='index.php';</script>"; exit; } print("</pre>");
希望本文所述对大家php程序设计有所帮助。
