Riap::TCP - Riap over TCP
version 1.1.15
Riap::TCP is a simpler alternative to Riap::HTTP. It supports less features (currently only supports JSON, no encryption, no authentication, no sending of logging messages). It is suitable for localhost/localnet communication (e.g. between processes of different languages). For public-facing service, Riap::HTTP is more recommended.
Client first sends a request line of the following format:
"J" <size> <CRLF>
That is, the letter J (for JSON) and size of subsequent request body in bytes. Client then sends the Riap request in JSON, followed by CRLF.
J
Alternatively, client can also send the whole request in a single line, for shorter requests:
"j" <JSON> <CRLF>
That is, the letter j followed by JSON data, followed by CRLF.
j
Server replies by first sending a similar line:
followed by enveloped result encoded in JSON and a single <CRLF>. The next request can then be sent by client.
If client/server sends an invalid request/response line, the connection can be closed.
1.1
This document specifies using Riap directly over TCP, or Riap::TCP for short.
Below are some examples of what is sent and received on the wire.
J9 {"v":0.9} J40 [502,"Protocol version not implemented"] J1 { J20 [400,"Invalid JSON"] J57 {"action":"call","uri":"/Math/mult","args":{"a":2,"b":3}} J12 [200,"OK",6] j{"action":"call","uri":"/Math/mult","args":{"a":2,"b":4}} J12 [200,"OK",8] J44 {"v":1.1,"action":"info","uri":"/Math/mult"} J57 [200,"OK",{"v":1.1,"type":"function","uri":"/Math/mult"}]
