procbridge-python

ProcBridge is a super-lightweight IPC (Inter-Process Communication) protocol over TCP socket or Unix domain socket. It enables you to send and recieve JSON between processes easily. ProcBridge is much like a simplified version of HTTP protocol, but only transfer JSON values.

Please note that this repo is the Python implementation of ProcBridge protocol. You can find detailed introduction of ProcBridge protocol in the main repository: gongzhang/procbridge.

Installation

pip install procbridge==1.2.1

Example

Server Side:

import procbridge as pb

def delegate(method, args):

    # define remote methods:
    if method == 'echo':
        return args

    elif method == 'sum':
        return sum(x for x in args)

    elif method == 'err':
        raise RuntimeError("an server error")


if __name__ == '__main__':
    PORT = 8000
    s = pb.Server('0.0.0.0', PORT, delegate)
    s.start(daemon=False)
    print("Server is on {}...".format(PORT))

Client Side:

import procbridge as pb
client = pb.Client('127.0.0.1', 8000)

# call remote methods:
client.request("echo", 123) # 123
client.request("echo", ['a', 'b', 'c']) # ['a', 'b', 'c']
client.request("sum", [1, 2, 3, 4]) # 10
