How do I pass a variable into a URL in a Perl script? I am trying to pass the variables in an array to url. For some reason it is not working. I am not sure what I am doing wrong. The code roughly looks like this:
@coins = qw(Quarter Dime Nickel);
foreach (@coins) {
my $req = HTTP::Request->new(POST =>'https://url/$coins.com');
}
This does not work as $coins
does not switch to Quarter,Dime,Nickel respectively.
What am I doing wrong?
First, variables do not interpolate in single quoted strings:
my $req = HTTP::Request->new(POST => "https://url/$coins.com");
Second, there is no variable $coins
defined anywhere:
foreach my $coin (@coins) {
my $req = HTTP::Request->new(POST => "https://url/$coin.com");
}
Also, make sure to use strict and warnings .
You should also invest some time into learning Perl properly.
Use
'https://url/' . $_ . '.com'
Instead of your
'https://url/$coins.com'
