The two JSON RPC libs available at CPAN (Perl), and a compliant C lib that I wrote locally to verify the behavior.
Perl’s LWP module definitely sets the Content-Length header. I would’ve been surprised if it didn’t, since it is required by HTTP 1.0 and the HTTP 1.1 spec says clients ‘SHOULD’ set it.
After some struggle, I got the first JSON::RPC library at CPAN to work:
use JSON::RPC::Client;
use Data::Dumper;my $client = new JSON::RPC::Client;
$client->ua->credentials( ‘localhost:8332’, ‘jsonrpc’, ‘my rpcusername’ => ‘my rpcpassword’ # Replace with real user/pass ); my @foo = $client->ua->credentials(‘localhost:8332’, ‘jsonrpc’); print “@foo\n”;
my $uri = ‘http://localhost:8332/’;
my $obj = {
method => ‘getinfo’,
params => ],
};
my $res = $client->call( $uri, $obj );
if($res){ if ($res->is_error) { print “Error : ”, $res->error_message; } else { print Dumper($res->result); } } else { print $client->status_line; } The struggle was setting the realm to ‘jsonrpc’ (it is fussy about that). I’ll document that on the wiki.
