cushy-socket

cushy-socket

A lightweight python socket library. You can create a TCP/UDP connection easily.

Features

• send socket message easily
• listen socket message and support ballback
• support sending group messages to clients
• support decorator version listening
• listen topic message and callback

Usage

pip install cushy-socket --upgrade 

Here are some minimal example programs using the cushy-socket: a server that echoes all data that it receives back(servicing only one client), and a client using it.

• Now let's build a easy echo demo.The first example support IPv4 only.

# echo tcp server program
import socket
from cushy_socket.tcp import CushyTCPServer

cushy_tcp_server = CushyTCPServer(host='localhost', port=7777)
cushy_tcp_server.run()


@cushy_tcp_server.on_connected()
def handle_on_connected(sock: socket.socket):
    print(f"[server decorator callback] new client connected.")
    print(sock)


@cushy_tcp_server.on_disconnected()
def handle_on_disconnected(sock: socket.socket):
    print(f"[server decorator callback] a client disconnected.")
    print(sock)


@cushy_tcp_server.on_message()
def handle_msg_from_client(msg: str, socket: socket.socket):
    print(f"[server decorator callback] cushy_tcp_server rec msg: {msg}")
    cushy_tcp_server.send("hello, I am server")

# echo tcp client program
from cushy_socket.tcp import CushyTCPClient

cushy_tcp_client = CushyTCPClient(host='localhost', port=7777)
cushy_tcp_client.run()


@cushy_tcp_client.on_connected()
def handle_on_connected():
    print(f"[client decorator callback] connect to server.")


@cushy_tcp_client.on_disconnected()
def handle_on_disconnected():
    print(f"[client decorator callback] server disconnected.")


@cushy_tcp_client.on_message()
def handle_msg_from_server(msg: str):
    print(f"[client decorator callback] cushy_tcp_client rec msg: {msg}")


cushy_tcp_client.send("hello, here is CSTCP client")
cushy_tcp_client.close()

TODO

• support for more lifecycle callbacks
• optimize the handle of socket closing
• optimize syntax expressions
• add UDP server/client support
• provide more solutions
• provide more async supports
• provide more decorator support
• optimize unittest
• send and listen topic message
