偷别的站也是一个道理.关键是方法.小偷就是用ASP,PHP或者其他语言在程序中打开并且处理这些HTML

error_reporting(E_ALL&~E_NOTICE);
 
$url = http://www.baoluowanxiang.com/Index/xxx/id/100; //从此站抓取数据
 
$fp = @fopen($url, "r") or die("超时"); //打开指定的网页
 
$fcontents = file_get_contents($fp); //获取网页html源码
 
$str_html = "/(.*)/ "; //正则表达式
preg_match($str_html, $fcontents, $regs); //检索需要的数据
 
$regs[1] = str_replace("src=\"..\/images\/", "src=\"http://www.xxxcom\/images\/", $regs[1]);
 
echo $regs[1];
Copy after login
