不是过滤
是根本没接收

看错，接收呢，用in函数

代码最好用

[ /code] 括起来。不然看的好累。。

原因很简单。程序太好了。。。只处理最后一个 ？ 后面的地址。。

而这段代码是出在函数 ReadParse 中的。。而你并没有提供这个函数。。也就是这个文件没有办法修改，因为原因不在这个文件中。

或者。。你可以这样子改？
[code]&ReadParse;

use CGI;
my $q=new CGI;
$in_url = $q->param('url');

这个程式好像是咱们PERLCHINA现任老大
风云howwa写的。。。。。。。

不好意思,最近一直上不来,小区的网络有问题

我把程序打包上来吧,实在很难看懂,不过这样的程序很实用.希望能多学习了.

光是解析个数据就写这么多
真是强啊~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
我已经没有耐心看下去了

汗。。太长了。我建议你还是找原作者"飞云"帮忙吧。。
在这里 http://bbs.perlchina.org/pl/ccb/index.cgi  可以找到他，他的ID是  hoowa ，那里的老大：）

知道啊 因为我们LB之前也是用过这个库的
为什么木头总喜欢说一些大家都知道的事情？
恩

汗。
