<div>
the problem isn't separating the arguments. <br />
It is really the decoding of the parameters.<br />
<br />
You also need to think at least in this cases:<br />
<br />
<a href="http://www.example.com/xpto?a=b&a=c&q=c%26a" rel="ugc">http://www.example.com/xpto?a=b&a=c&q=c%26a</a><br />

</div>


<div>
So you need to URL decode hex escapes.<br />
<br />
Like thsi:<br />
<br />
$param = 'c%26a';<br />
$param =~ s/\%([a-fA-F0-9]{2})/pack(<wbr />'C', hex($1))/gse;<br />
<br />

</div>


<div>
we are in Apach2 and mod_perl. <br />
<br />
This is the standard way of doing this ? ? ?
</div>

Well, since you were accessing the query string directly, in scalar context, I assumed you wanted to decode the query string yourself. Otherwise, if the API did it for you even in scalar context, parsing the string would be impossible because it would have un-escaped all the &amp;&nbsp;and you would not know which were separators and which were actual &amp;&nbsp;in the content.<br />
<br />
I think you should try the $r-&gt;args() in lsit context.<br />
<br />
What happens when you do:<br />
<br />
my %keypairs = $r-&gt;args();<br />
<br />
This should decode for you, as it is supposed to mirror the CGI API.<br />
<br />
<br />

</div>


<div>
I thought you asked for it in the original format, without decoding, if you want to decode the parameters, you probably want to use the standard API
</div>


<div>
maybe I'm missing a Package but the code:<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; my %keypairs = $r-&gt;args();<br />
&nbsp; &nbsp; &nbsp; &nbsp; print Dumper \%keypairs;<br />
<br />
prints<br />
<br />
$VAR1 = {<br />
&nbsp; 'a=b&amp;c=d' =&gt; undef<br />
};<br />
<br />
for the linux command:<br />
<br />
POST '<a href="http://localhost:10000/media_server/download_request?a=b&c=d'" rel="ugc">http://localhost:10000/media_server/download_request?a=b&c=d'</a> &lt;&nbsp;test_data.json
</div>


<div>
Apparently there is some inaccurate documentation for the mod_perl Apache module. Try this snippet, which came from this URL. According to docs, the Apache::args provides unescaped values, as best I can tell.<br />
<br />
<a href="http://www.informit.com/articles/article.aspx?p=27110&seqNum=7" rel="ugc">http://www.informit.com/articles/article.aspx?p=27110&seqNum=7</a><br />
<br />
Try Apache::Request instead.<br />

<pre><code class="code-10 nolinks" id="code-276976"><span>use Apache::Request;</span>
<span> </span>
<span>sub handler {</span>
<span> </span>
<span> my $r = Apache::Request-&gt;new(shift);</span>
<span> </span>
<span> $r-&gt;send_http_header('text/plain');</span>
<span> </span>
<span> # Now, we use the param() method, which covers both GET and POST data.</span>
<span> foreach my $param ($r-&gt;param) {</span>
<span>  print &quot;$param =&gt; &quot;, $r-&gt;param($param), &quot;\n&quot;;</span>
<span> }</span>
</code></pre>
</div>


<div>
I meant &quot;Apache::args provides escaped values, as best I can tell&quot;
</div>


<div>
For Apache 2 you use Apache2::* you don't use Apache::*

In a request like <br />
<br />
<a href="http://www.example.com/xpto?a=b&c=d" rel="ugc">http://www.example.com/xpto?a=b&c=d</a><br />
<br />
from the $r-&gt;args I get the &quot;a=b&amp;c=d&quot;<br />
<br />
Now I need to split the args into a hash to get the arguments in the original format, without encodings. <br />
<br />
How do I do this?<br />

In a request like 

http://www.example.com/xpto?a=b&c=d

from the $r->args I get the "a=b&c=d"

Now I need to split the args into a hash to get the arguments in the original format, without encodings. 

How do I do this?



split the args in Apache2 mod_perl

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
