前言

本来是为了局域网内能够复制段儿代码方便远程调试用的，ssh当然也可以，当然还是我头脑风暴散发，想到这里了。于是从网上拉了一个，改通之后，留一个备份。

期望还是很好的，以后用来支持ubuntu聊天之类的，当然这就得在html上来，不急慢慢来

代码

服务端代码：

import socket
import time
from threading import Thread

# 创建socket,绑定地址和端口号
host = '192.168.8.221'
port = 12345
# 创建套接字
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host, port))  # 绑定地址和端口号

# 存放用户昵称和地址
client = {}
address = {}
# 服务器可接收的client连接数
accept_num = 10


def client_join(conn, add):  # 新客户端加入
    print("为新用户建立进程")
    nikename = conn.recv(1024).decode('utf8')
    welcome = f'欢迎{nikename}加入聊天室'
    print(welcome)
    client[conn] = nikename  # 将客户端加入client
    brodcast(bytes(welcome, 'utf8'))  # 广播欢迎信息
    while True:
        time.sleep(0.1)
        try:
            msg = conn.recv(1024)
            print(msg)
            brodcast(msg, nikename + ':')  # 广播聊天信息
        except:
            print("接收失败")
            conn.close()
            client[conn]=None
            brodcast(bytes(f'{nikename}离开聊天室\n', 'utf8'))  # 用户断开连接


def brodcast(msg, nikename=''):  # 向所有客户端广播新信息
    for conn in client:
        print(f"向{conn} 发送 {msg}")
        conn.send(bytes(nikename, 'utf8') + msg)
        print("发送成功")


if __name__ == '__main__':
    s.listen(accept_num)
    print('服务器已开启，正在监听用户请求')
    while True:
        conn, add = s.accept()
        print(add, '已建立连接')
        conn.send('欢迎来到聊天室,请输入你的昵称后进行聊天\n'.encode('utf8'))
        address[conn] = add
        Thread(target=client_join, args=(conn, add)).start()  # 为新连接的客户端建立新线程

客户端代码：

import socket
import traceback
from threading import Thread
import tkinter as tk

# socket接入
host = '192.168.8.221'
port = 12345
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))


def get_msg():
    global text_message
    while True:
        try:
            msg = s.recv(1024).decode('utf8')
            print(f"得到了一些消息：{msg}")
            text_message.insert(tk.END, msg)  # 接收到广播信息时显示在消息窗口
        except (BaseException, Exception) as e:
            print(traceback.format_exc())

            break



# 绘制GUI
app = tk.Tk()
app.title('多人聊天室')

# 消息窗口
message_frame = tk.Frame(width=480, height=300, bg='white')  # 划分Frame
text_message = tk.Text(message_frame)
message_frame.grid(row=0, column=0, padx=3, pady=6)  # 0行0列，边框距离x=3px,y=6px
message_frame.grid_propagate(0)  # 固定面板大小
text_message.grid()

# 输入窗口
text_frame = tk.Frame(width=480, height=100)
text_text = tk.Text(text_frame)
text_frame.grid(row=1, column=0, padx=3, pady=6)
text_frame.grid_propagate(0)
text_text.grid()



# 发送按钮
def send():
    send_msg = text_text.get('0.0', tk.END)  # 获取输入窗口文本内容
    # print(send_msg)
    s.send(send_msg.encode())
    text_text.delete('0.0', tk.END)  # 清空输入窗口文本内容

receive_thread = Thread(target=get_msg)  # 开启线程用于接收广播信息
receive_thread.start()
print('连接服务器成功')

send_frame = tk.Frame(width=480, height=30)
button_send = tk.Button(send_frame, text='发送', command=send)  # 添加按钮并绑定发送功能
send_frame.grid(row=2, column=0, padx=10, sticky='E')  # 2行0列,右对齐，距离边框10px
# send_frame.grid_propagate(0)
button_send.grid()

app.mainloop()
