Dear experts,

I have a cgi scripts which is write in python for send sms and locate at /usr/local/apache/cgi-bin/sendsms

How can I use perl to run or call that cgi scripts?

I have try to do like this

sub sendsms()
$sendsms=`lynx -dump "http://www.xxxtesting.com:13013/cgi-bin/sendsms?&user=xxx&pass=xxx&from=&to=xxx&text=xxx"`;
print $sendsms;

if $text no spaceing it is OK but if $text has spaceing it has problems, and I think if we can replace spacing with a "+" sign it will also OK. Are there any methods can fix it or are there any BETTER methods?

Please help!

Thanks alot!

surely. What you want to do is URLENCODE that url. There are a number of tools to do this.  Here is a quick one which will just replace the spaces with the +

lets say your URL is kept in a variable $url.

to replace all spaces with a + sign, you can do something like this.

$url =~ s/ /\+/g;

Perl is great about being able to do regular expression matching and replacing.  A really good start would be to read the perl regular expression POD.  perldoc perlre

Another (more correct?) substitution for spaces in urls is %20, so you would do:

$url =~ s/ /\%20/g;

Just wonder, any other methods can call the cgi? It seem not a good method to run a cgi script by pass a command to the shell and run lynx?

Perl has a great library called LWP. It is basically a perl module you can use to get data from an HTTP server(you can get ftp and other stuff too)

here is a really simple way to use it(it can be MUCH more flexible and powerful)


use LWP::Simple;

$url = 'http://www.xxxtesting.com:13013/cgi-bin/sendsms?&user=xxx&pass=xxx&from=&to=xxx&text=xxx'

$doc= get $url;


thats it. it will post the data to the cgi script and grab whatever information comes back and store it in the $doc variable.

its pretty slick.
