How do I access a value of a nested Perl hash?
- by st
I am new to Perl and I have a problem that's very simple but I cannot find the answer when consulting my Perl book.
When printing the result of
Dumper($request);
I get the following result:
$VAR1 = bless( {
'_protocol' => 'HTTP/1.1',
'_content' => '',
'_uri' => bless( do{\(my $o = 'http://myawesomeserver.org:8081/counter/')}, 'URI::http' ),
'_headers' => bless( {
'user-agent' => 'Mozilla/5.0 (X11; U; Linux i686; en; rv:1.9.0.4) Gecko/20080528 Epiphany/2.22 Firefox/3.0',
'connection' => 'keep-alive',
'cache-control' => 'max-age=0',
'keep-alive' => '300',
'accept' => 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'accept-language' => 'en-us,en;q=0.5',
'accept-encoding' => 'gzip,deflate',
'host' => 'localhost:8081',
'accept-charset' => 'ISO-8859-1,utf-8;q=0.7,*;q=0.7'
}, 'HTTP::Headers' ),
'_method' => 'GET',
'_handle' => bless( \*Symbol::GEN0, 'FileHandle' )
}, 'HTTP::Server::Simple::Dispatched::Request' );
How can I access the values of '_method' ('GET') or of 'host' ('localhost:8081').
I know that's an easy question, but Perl is somewhat cryptic at the beginning.
