Bio::Root::HTTPget - module for fallback HTTP get operations when LWP:: is unavailable
use Bio::Root::HTTPget;
my $web = Bio::Root::HTTPget->new();
my $response = $web->get('http://localhost');
$response = $web->get('http://localhost/images');
$response = eval { $web->get('http://fred:secret@localhost/ladies_only/')
} or warn $@;
$response = eval { $web->get('http://jeff:secret@localhost/ladies_only/')
} or warn $@;
$response = $web->get('http://localhost/images/navauthors.gif');
$response = $web->get(-url=>'http://www.google.com',
-proxy=>'http://www.modperl.com');
This is basically an last-chance module for doing network HTTP get requests in situations where more advanced external CPAN modules such as LWP:: are not installed.
The particular reason this module was developed was so that the Open Bio Database Access code can fallback to fetching the default registry files from http://open-bio.org/registry/ without having to depend on external dependencies like Bundle::LWP for network HTTP access.
The core of this module was written by Lincoln Stein. It can handle proxies and HTTP-based proxy authentication.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.
