How do I write a simple HTTP proxy in Perl?
I don't want to use the HTTP :: Proxy package because I want to drop a couple of requests. My one liner looks like this but breaks down trying to pass the header to:
perl -MData::Dumper -MHTTP::Daemon -MHTTP::Status -MLWP::UserAgent -e 'my $ua = LWP::UserAgent->new;my $d=new HTTP::Daemon(LocalPort=>1999);print "Please contact me at: <", $d->url, ">\n";while (my $c = $d->accept) {while (my $r = $c->get_request) {if ($r->method eq 'GET' and $r->url->path eq "/uploader") {$c->send_response("whatever.");print Dumper($r);}else{$response=$ua->request($r->method,"http://localhost:1996".$r->uri,$r->headers,$r->content);$c->send_response($response);}}}'
formatted, that is:
#perl -e '
use Data::Dumper;
use HTTP::Daemon;
use HTTP::Status;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
my $d=new HTTP::Daemon(LocalPort=>1999);
print "Please contact me at: < ", $d->url, " >\n";
while (my $c = $d->accept) {
while (my $r = $c->get_request) {
if ($r->method eq 'GET' and $r->url->path eq "/uploaded") {
$c->send_response("whatever.");
print Dumper($r);
} else {
$response = $ua -> request(
$r->method,
"http://localhost:1996" . $r->uri,
$r->headers,
$r->content);
$c->send_response($response);
}
}
}#'
So I can't just pass the request because I need to change the host and I can't just pass it in the headers ... so what I have to do is to keep it short.
So can anyone do it better with one liner?

Aw shoot, I fixed it like this:
#perl -e '
use Data::Dumper;
use HTTP::Daemon;
use HTTP::Status;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
my $d=new HTTP::Daemon(LocalPort=>1999);
print "Please contact me at: < ", $d->url, " >\n";
while (my $c = $d->accept) {
while (my $r = $c->get_request) {
if ($r->method eq "GET" and $r->url->path eq "/uploaded") {
$c->send_response("whatever.");
print Dumper($r);
} else {
$response = $ua -> request( HTTP::Request->new(
$r->method,
"http://localhost:1996" . $r->uri,
$r->headers,
$r->content));
$c->send_response($response);
}
}
}#'
Notice HTTP::Request->new
yes ... this is how it works, it's a bit slow. but it normal
