本文介绍了一种基于多线程的算法响应框架，能够处理来自不同客户端的算法执行请求，即使客户端断开连接也能正常运行。服务器使用Python的socketserver模块实现，能够接收并解析JSON格式的消息，调用相应的算法函数进行处理。

需要实现客户端发来的算法执行请求，写了一个多线程的响应框架，能够实现响应多个IP的请求，并且不受客户端断开的影响。

服务器端

import socketserver
import json
class Algrithom(object):
    def __init__(self,name):
        self.name = name

    def calc_sub(self,*args):
        para_inside=args
        print(type(para_inside))
        print("%s is running calc_sub,and para is %s"%(self.name,para_inside))

def calc_undefine():
    print("This function is undefined....")

class MyTCPHandler(socketserver.BaseRequestHandler):
    def handle(self):
        a = Algrithom("AIwater")
        count=0
        while True:
            try:
                self.data =self.request.recv(1024).strip()
                msg_dic = json.loads(self.data.decode())
                print("{} wrote:".format(self.client_address[0]))
                # with open('D:/server.log', 'w') as f:
                #     f.write(self.client_address[0])
                print(msg_dic)
                function=msg_dic["function"]
                para=msg_dic["para"]

                if hasattr(a,function):
                    func=getattr(a,function)
                    func(para)
                    self.request.send("Algrithom finish".encode('utf-8'))
                else:
                    setattr(a,function,calc_undefine)
                    func = getattr(a, function)
                    func()
                    self.request.send("Function is undefined".encode('utf-8'))
                count+=1
                if count >10:break

            except ConnectionResetError as e:
                print("err",e)
                break

if __name__ == "__main__":
    HOST, PORT = "localhost", 6969
    # Create the server, binding to localhost on port 6969
    server = socketserver.ThreadingTCPServer((HOST, PORT), MyTCPHandler)
    server.allow_reuse_address
    server.serve_forever()

测试用客户端

import socket
import json
client = socket.socket() #声明socket类型，同时生成socket连接对象
client.connect(('localhost',6969))
client.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
while True:
    function = input("Please input function:").strip()
    para = input("Please input para:").strip()
    msg_dic={"function":function,
             "para":para}
    if len(function) == 0:continue
    client.send(json.dumps(msg_dic).encode("utf-8"))
    data = client.recv(1024)
    print("recv:",data.decode())

client.close()
