PyRPC

PyRPC is a simple RPC-framework written in Python. It supports simple and fast access to remotely provided procedures by pickling (using the fast but in-secure module cPickle, see below) all data (request/response) and transporting it via TCP to the remote host.

Due to it's nature, cPickle is not intended to be secure. Under special circumstances (e. g. malicious messages) remote executions might be possible. Therefore you must ensure that the server is only reachable by trusted clients in a secure and restricted environment (a public server is therefore absolutely not recommended).

Transmission is compressed using zlib.

Installation

PyRPC is available at PyPI and known as fspyrpc:

pip install fspyrpc

Usage

Using PyRPC is pretty simple. See client_example.py for client-usage. The server consists of two classes:

  • RPCServer
  • RPCServerHandler

RPCServer is used to manage all client connections; the RPCServerHandler is newly instantiated for every request. It implements all provided procedures to the client; the method name is prefixed by handle_.

Every called method has access to the following instance attributes:

  • address - contains a (ip, port)-tuple of the remote client address
  • data - provides raw access to the request as a dict-object

See server_example.py for corressponding server-usage.
