Problem summary:
JRPC::Client does not support calls where the request object has no "params" value.
Problem description:
The JSON-RPC 2.0 spec says that "params" may be ommitted. See http://www.jsonrpc.org/specification#request_object
params
A Structured value that holds the parameter values to be used during the invocation of the method. This member MAY be omitted.
However when there are no parameters, JRPC::Client's call method dies. JRPC::Client::call always expects $params to either be a reference or well-formed JSON string.
Steps to reproduce:
$ perl -MJRPC::Client -e 'my $client = JRPC::Client->new; my $request = $client->new_request(q{http://localhost/}); $request->call("some_method", undef)'
Use of uninitialized value $param in pattern match (m//) at /usr/local/share/perl5/JRPC/Client.pm line 164.
Use of uninitialized value $param in concatenation (.) or string at /usr/local/share/perl5/JRPC/Client.pm line 168.
Malformed JSON body () at /usr/local/share/perl5/JRPC/Client.pm line 168.
