Use socket and threading to create a multi-threaded chat

Use socket and threading to create a multi-threaded chat today

ready:

1. One computer with virtual machine (VMware) installed (or two computers (￣︶￣)↗)
2. Both the host and the virtual machine have python installed, and both have IDEs

My configuration:

1. win10 host, Ubuntu virtual machine
2. IDE is pycharm

Before creating a chat tool, we need to know the ip of the host and virtual machine.
For Ubuntu, right-click to open the terminal and enter the command to view the ip

ifconfig

For win, win+cmd open the terminal, enter the command to view ip

ipconfig

My win host ip and virtual machine ip are respectively

192.168.1.2 # win
192.168.48.142 # Ubuntu

on windows

import socket
import threading

def recv(udp_socket):
    while True:
        msg=udp_socket.recv(1024)
        print(msg.decode('utf-8'))
        
def send(udp_socket,addr):
    while True:
        msg=input("输入:")
        udp_socket.sendto(msg.encode('utf-8'),addr)
        
def main():
    
    # 1. 创建套接字
    udp_socket=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    
    # 2. 绑定ip和port
    udp_socket.bind(('192.168.1.2',7892))
    
    # 3.对方的ip和port
    addr=('192.168.48.142',7893)
    
    # 4. 创建线程
    
    t_send=threading.Thread(target=send,args=(udp_socket,addr))
    t_recv=threading.Thread(target=recv,args=(udp_socket,))
    
    t_send.start()
    t_recv.start()
    
    
    
if __name__=='__main__':
    main()

On the virtual machine

import socket
import threading

def recv(udp_socket):
    while True:
        msg=udp_socket.recv(1024)
        print(msg.decode('utf-8'))
        
def send(udp_socket,addr):
    while True:
        msg=input("输入:")
        udp_socket.sendto(msg.encode('utf-8'),addr)
        
def main():
    
    # 1. 创建套接字
    udp_socket=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    
    # 2. 绑定ip和port
    udp_socket.bind(('192.168.48.142',7893))
    
    # 3.对方的ip和port
    addr=('192.168.1.2',7892)
    
    # 4. 创建线程
    
    t_send=threading.Thread(target=send,args=(udp_socket,addr))
    t_recv=threading.Thread(target=recv,args=(udp_socket,))
    
    t_send.start()
    t_recv.start()
    
    
    
if __name__=='__main__':
    main()

Of course, the same computer can also communicate with each other (same ip), as long as the ports are different.
