It merely allows to ease +parsing of messages a bit by putting things into a record. + +Let's assume you receive UDP datagrams in a gen_server. You can then match on +the incoming coap message like: + + handle_info({udp, Socket, Host, Port, Bin}, State) -> + Msg = coap_parse:parse(Bin), + case Msg of + #coap_request{method=post, path= <<"/switches">>, query=[<<"name=", Name/binary>>], payload=Payload} -> + ... + +Which would allow you to process a request like: + + echo '{"mode": "on"}' | coap-client -f- -t application/json -m post "coap://[::1]/switches?name=Lever1" |
