php实现的网络相册图片防盗链完美破解方法

本文实例讲述了php实现的网络相册图片防盗链完美破解方法。分享给大家供大家参考。具体如下：
网络相册图片防盗链破解程序 - PHP版这个防盗链破解版可以完美破解当下比较流行的: 百度相册,网易相册,360我喜欢等网站图片. 还可以实现简单的图片防盗链. 因为这个类是先进行获取远程图片, 然后再把图片发送到客户端,所以,算是进行了两次流量的传送.因此,会浪费空间流量,接下来,会开发缓存功能,这样可以实现节约流量！
<?php/*** 网络相册图片防盗链破解程序 - PHP版** 使用方法：* * http://yourdomain/url.php?url=http://hiphotos.baidu.com/verdana/pic/item/baidupicture.jpg&referer=* 其中url是指需要破解的图片URL,而referer是为了兼容一些不需要设置来路域名才能显示的相册,例如360我喜欢网,必须设置来路为空才能正常浏览. 所以,此时应该设置referer为1 ** @author 雪狐博客* @version 1.0* @sinceJuly 16, 2012 * @URL http://www.xuehuwang.com*/class Frivoller { /*** HTTP 版本号 （1.0, 1.1） , 百度使用的是 version 1.1** @var string*/protected $version; /*** 进行HTTP请求后响应的数据 ** @var 字符串格式*/protected $body; /*** 需要获取的远程URL ** @var 字符串格式*/protected $link; /*** An array that containing any of the various components of the URL.** @var array*/protected $components; /*** HTTP请求时HOST数据 ** @var 字符串*/protected $host; /*** The path of required file.* （e.g. "/verdana/abpic/item/mygirl.png"）** @var string*/protected $path; /*** The HTTP referer, extra it from original URL** @var string*/protected $referer; /*** The HTTP method, "GET" for default** @var string*/protected $method= "GET"; /*** The HTTP port, 80 for default** @var int*/protected $port = 80; /*** Timeout period on a stream** @var int*/protected $timeout = 100; /*** The filename of image** @var string*/protected $filename; /*** The ContentType of image file.* image/jpeg, image/gif, image/png, image** @var string*/protected $contentType; /*** Frivoller constructor** @param string $link*/public function __construct（$link,$referer=""） { $this->referer = $referer;// parse the http link $this->parseLink（$link）; // begin to fetch the image $stream = pfsockopen（$this->host, $this->port, $errno, $errstr, $this->timeout）; if （！$stream）{header（"Content-Type: $this->contentType;"）; echo $this->CurlGet（$link）; }else{ fwrite（$stream, $this->buildHeaders（））; $this->body = ""; $img_size = get_headers（$link,true）;while （！feof（$stream）） { $this->body .= fgets（$stream, $img_size["Content-Length"]）; //fwrite（$jpg,fread（$stream, $img_size["Content-Length"]））;} $content = explode（"
