# ...or, alternatively, use https:
# $url = "https://metacpan.org/pod/Data::Dumper";
set_redir_max(3); # Max. number of redirections
set_timeout(10); # Timeout in seconds
my $obj = Acme::HTTP->new($url) || die $@;
my $code = get_code();
my $msg = get_message();
if ($code eq '404') {
die "Page '$url' not found";
}
elsif ($code ne '200') {
die "Page '$url' - Error $code, Msg '$msg'";
}
print "Orig url = ", $url, "\n";
print "Real url = ", get_url_act(), "\n";
print "Redirections = ", get_redir_act(), "\n";
print "Length = ", get_response()->{'Content-Length'} // 0, "\n";
print "\n";
while (1) {
my $n = $obj->read_entity_body(my $buf, 4096);
die "read failed: $@" unless defined $n;
last unless $n;
print $buf;
}
PARAMETERS
The following parameters can be set in advance:
- set_redir_max($count)
-
Set the maximum number of redirections
- set_timeout($sec)
-
Set the timout in seconds
RETURN VALUES
The following variables are available read-only after new():
- get_url_act()
-
returns the actual url after redirection
- get_redir_act()
-
returns the actual number of redirection that have taken place
- get_code()
-
returns the HTTP status
- get_message()
-
returns the HTTP message
- get_response()
-
returns a hash-reference of the response variables
List of values
In case of a successful new(), the subroutines get_code() and get_message() are usually set as follows:
get_code() => '200'
get_message() => 'OK'
However, a non-existing address would typically return different values:
get_code() => '404'
get_message() => 'Not Found'
Here is one sample result of get_response() of an MP3 file:
'Content-Type' => 'audio/mpeg'
'Content-Length' => '28707232'
'Date' => 'Sun, 17 Aug 2014 10:53:43 GMT'
'Last-Modified' => 'Thu, 10 Jul 2014 04:52:52 GMT'
'Accept-Ranges' => 'bytes'
'Connection' => 'close'
'Cache-Control' => 'max-age=2269915'
'ETag' => '"1404967972"'
'X-HW' => '1408272823.dop...pa1.c'
...and here is another example result of get_esponse() of a web page:
'Content-Type' => 'text/html; charset=utf-8'
'Content-Length' => '31569'
'Date' => 'Sun, 17 Aug 2014 11:02:54 GMT'
'Last-Modified' => 'Thu, 24 Jul 2014 03:31:45 GMT'
'Accept-Ranges' => 'bytes'
'Connection' => 'close'
'Age' => '0'
'Set-Cookie' => '...expires=12-Sep-2031...; secure',
'Server' => 'nginx/0.7.67',
'Vary' => 'Accept-Encoding,Cookie'
'Via' => '1.1 varnish',
'X-Cache' => 'MISS, MISS',
'X-Cache-Hits' => '0, 0',
'X-Runtime' => '0.479137'
'X-Served-By' => 'cache-lo80-LHR, cache-fra1222-FRA',
