SockServer

A very tiny RPC framework, with ability to perform basic type checks.

Screenshot

Install

pip3 install sockserver -U

Usage

from SockServer import SockServer

server = SockServer(8000, workers=8)


@server.register()
def hello(who: str):
    """
    :param who:
    :return:
    """
    if who == "me":
        return {
            "status": False,
            "result": "you are not allowed to say hello to yourself",
        }
    return {"status": True, "result": "hello " + who.strip()}


if __name__ == '__main__':
    server.start()

Support Qpro Template

Qpro create <server_name>

# Choose "内置模板 / Inner Template" -> "SockServer"

Client Lib for C

• Install Client LIB

mkdir -p /usr/local/include/SockClient
cp Client/utils/* /usr/local/include/SockClient/

• Usage

#include <SockClient/SockClient.h>
#include <SockClient/cJSON.h>

    * 服务端地址与端口，请自行修改
