设置“href”在样式表中链接到可执行脚本？ [英] Setting the "href" in a stylesheet link to an executable script?
问题描述
我最近注意到html页面中的样式表链接有一个href设置
到PHP脚本，如：
< LINK REL = "样式表" HREF =" some_css.php" type =" text / css">
大概是被引用的文件实际上是一个可执行的PHP
脚本而不是碰巧有的css文件一个.php扩展名。
基于这个假设，我用Perl脚本尝试了同样的事情
（正在测试的网络服务器碰巧安装了mod_perl但没有安装
mod_php），如：
< LINK REL =" stylesheet" HREF =" dyn_css.pl" type =" text / css">
结果是一个服务器错误，其中包含error_log条目：
Bareword找到了运营商预期的位置在
/srv/www/plwa/test/dyn_css.html第4行，靠近" dyn_css.pl输入
（类型之前缺少运算符？）
Perl脚本返回一个简单的样式表对象...
body {
background-color：＃000000;
font-family：Verdana;
font-size：10px;
颜色：#FFFFFF;
边框：5px实心#AAAAAA;
}
....这正是上面提到的PHP脚本在wget检索
时返回的内容。
因此，问题是：是否可以在
样式表链接？如果是这样的话，可以随便评论我为什么会从服务器上获得上述错误吗？
O / S：SuSE Linux 8.x
服务器：带有mod_perl的Apache 2.x（.pl文件与使用AddHandler语句的
perl-script处理程序相关联）。
谢谢！

如果能够做到这一点，这是非常有趣的..你有没有看过服务器为php文件返回的内容类型？
内容类型？使用wget获取返回的
标头（wget -S）。很可能他们已经将内容类型设置为
text / css而不是php脚本常用的文本/ html。
在PHP中你会改变这样的标题：
header（" Content-Type：text / css"）
在将任何内容输出到客户端之前。
这可能是他们正在做的事情。
Stian
一个很好的假设，但根据wget -S返回的类型是
text / html：

您的服务器是否配置为对具有扩展名的文件运行perl
" pl" ？

I recently noticed the stylesheet link in an html page had the href set
to a PHP script, as in:
<LINK REL="stylesheet" href="some_css.php" type="text/css">
Presumably the file being referenced was actually an executable PHP
script and not a css file that happened to have a .php extension.
Based on that assumption, I tried the same thing with a Perl script
(the webserver being tested happens to have mod_perl installed but not
mod_php), as in:
<LINK REL="stylesheet" href="dyn_css.pl" type="text/css">
The result was a server error with the error_log entry:
Bareword found where operator expected at
/srv/www/plwa/test/dyn_css.html line 4, near ""dyn_css.pl" type"
(Missing operator before type?)
The Perl script returns a simple stylesheet object...
body {
background-color: #000000;
font-family: Verdana;
font-size: 10px;
color: #FFFFFF;
border: 5px solid #AAAAAA;
}
.... which is exactly what the aforementioned PHP script returned when
retrieved by wget.
So, the question is: can an executable script be referenced in a
stylesheet link? If so, can anyome comment on why I might be getting
the above error from the server?
O/S: SuSE Linux 8.x
Server: Apache 2.x with mod_perl (.pl files associated with the
perl-script handler using an AddHandler statement).
Thanks!

This is quite interesting if it can be done ... have you looked into what
content-type the server is returning for the php file? Use wget to get the
headers returned (wget -S). Most likely they have set the content-type to
text/css and not text/html which is usual for php scripts.
In PHP you would change the header something like this:
header("Content-Type: text/css")
before any content is output to the client.
It might be what they are doing.
Stian
A good hypothesis, but according to wget -S the type being returned is
text/html:
HTTP request sent, awaiting response...

Is your server configured to run perl on files that have the extension
"pl"?
