NAME

Riap::TCP - Riap over TCP

VERSION

version 1.1.10

DESCRIPTION

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.

Server replies by first sending a similar line:

"J" <size> <CRLF>

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.
