Something like this? Only handles a single request at a time, though.
#!/usr/bin/perl
use strict; # https://perlmonks.org/?node_id=11134663
use warnings;
use IO::Socket;
use IO::Select;
my $listen = IO::Socket::INET->new( LocalPort => 8080, # setup
Listen => 256, Reuse => 1) or die $@;
my $sel = IO::Select->new($listen);
sub checkforrequests
{
for my $fh ( $sel->can_read(0) ) # 0 for poll
{
my $socket = $fh->accept;
my $request = '';
1 while sysread $socket, $request, 4096, length $request
and not $request =~ /\n\r?\n/; # empty line test
print $request =~ s/^/got HTTP packet: /gmr; # FIXME for testing
# FIXME process request here
print $socket "OK\n"; # FIXME sample response
$request =~ /quit/ and die "exiting on 'quit'\n"; # FIXME for test
+ing
}
}
while( 1 ) # your loop as I understand it
{
select undef, undef, undef, 0.2; # FIXME your non-network stuff
checkforrequests(); # this is added to your loop
}
I used wget to talk to it, like this
wget -q -O - http://localhost:8080/CMD=changeplaylist
and I get an output of
got HTTP packet: GET /CMD=changeplaylist HTTP/1.1
got HTTP packet: User-Agent: Wget/1.21.1
got HTTP packet: Accept: */*
got HTTP packet: Accept-Encoding: identity
got HTTP packet: Host: localhost:8080
got HTTP packet: Connection: Keep-Alive
got HTTP packet:
A clever client could hang it if it tried. Should probably be done with a
more extensive multi-connection handler, but they get bigger :)
( Which is why monks, including me, will suggest using an async package.)
