Python的socket多线程编程实现(附可实现源码)

Using python language to complete socket multi-threaded programming and pseudo-intelligent communication through dictionary set.

The following shows part of the source code.

Server.py

import socket
import threading
import time
import os

#字典集返回数据
def getAnswer(c_data):
    words = {'how are you?': 'Fine,thank you.',  # 字典集
             'hi': 'hello',
             'hello': 'hello',
             'how old are you?': '20',
             'what is your name?': 'Andel,
             "what's your name?": 'Andel',
             'where do you work?': 'Beijing',
             'bye': 'Bye'
             }
    flag = 0
    lst = list(words.keys())
    for i in range(len(lst)):
        if len(os.path.commonprefix([c_data, lst[i]])) > len(lst[i]) * 0.8:
            flag = 1
            return words.get(lst[i])
    if flag == 0:
        return "Sorry for that, I don't understand what you say."
#接收信息
def recv_msg(clientsocket,clientaddress):
    while True:
        recv_data = clientsocket.recvfrom(1024)
        ip,port = clientaddress
        print('Received from client('+ str(ip) + ':' + str(port) +'):'+ recv_data[0].decode())
        t_send = threading.Thread(target=send_msg, args=(clientsocket, clientaddress, recv_data[0]))
        t_send.start()
#发送信息
def send_msg(clientsocket,clientaddress, recv_data):
    ip,port = clientaddress
    time_data =  str(time.asctime(time.localtime()) + "n")
    ans_data = getAnswer(recv_data.decode())
    send_data = time_data + ans_data

    clientsocket.sendto(send_data.encode(),(ip,port))
#
def main():
    serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    serversocket.bind(('127.0.0.1', 8000))
    serversocket.listen(5)
    print('Server connecting....')
    while True:
        clientsocket, clientaddress = serversocket.accept()
        t_recv = threading.Thread(target=recv_msg, args=(clientsocket,clientaddress))
        t_recv.start()
        # print(str(len(threading.enumerate())) +  "threads are working")
        #
        # if (len(threading.enumerate())<2):
        #     break

    serversocket.close()

if __name__  == "__main__":
    main()

Client.py

import socket                     				                 #导入socket模块

clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) #创建客户机socket
clientsocket.connect(('127.0.0.1', 8000))                        #连接到服务器
while 1:                                                         #循环以接收用户输入，并发送到服务器，接收服务器的回送数据
    data = input('>')             				                 #接收用户输入数据
    clientsocket.send(data.encode()) 		                     #把数据转换为bytes对象，并发送到服务器
    if data=='exit': break             			                 #如果数据为exit，终止循环
    newdata = clientsocket.recv(1024) 	                         #接收服务器的回送数据
    print('Received from server: ',  newdata.decode() )          #输出接收到数据
clientsocket.close()                			                 #关闭客户机socket

1. Python == 3.8
2. Pycharm

1. Click directory “threadingsocket”
2. Start the server first(server.py), Start the client1 and client2 then (client1.py + client2.py)
3. Input in client
4. Got response from server

2. The main function is to complete socket communication and multi-threaded tasks.
3. Regarding smart chat, bloggers try to call other open source third-party libraries, such as Turing bots, but they are not allowed to be used for free testing right now. If you have a better way to achieve truly intelligent chat, feel free to contact me.
