用python完成应用程序，实现两个人的聊天用TCP服务器客户端聊天，要求带输入框和输出框

好的，这里使用 Tkinter 库来实现 GUI 界面。

下面是服务器端代码：

import socket
import threading
import tkinter as tk


class Server:
    def __init__(self, ip, port):
        self.ip = ip
        self.port = port
        self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.server_socket.bind((self.ip, self.port))
        self.server_socket.listen(5)
        self.client_socket = None
        self.client_addr = None

        self.root = tk.Tk()
        self.root.title('Server')
        self.text_recv = tk.Text(self.root, width=50, height=20)
        self.text_recv.pack()
        self.text_send = tk.Text(self.root, width=50, height=5)
        self.text_send.pack()
        self.button_send = tk.Button(self.root, text='Send', command=self.send_message)
        self.button_send.pack()

    def accept_connection(self):
        self.client_socket, self.client_addr = self.server_socket.accept()
        self.text_recv.insert('end', 'Client %s:%s connected!\n' % self.client_addr)

    def receive_message(self):
        while True:
            recv_data = self.client_socket.recv(1024)
            if not recv_data:
                self.text_recv.insert('end', 'Client %s:%s disconnected!\n' % self.client_addr)
                break
            self.text_recv.insert('end', 'Received message from client: %s\n' % recv_data.decode('utf-8'))

    def send_message(self):
        send_data = self.text_send.get('1.0', 'end')
        self.client_socket.send(send_data.encode('utf-8'))
        self.text_send.delete('1.0', 'end')

    def start(self):
        threading.Thread(target=self.accept_connection).start()
        threading.Thread(target=self.receive_message).start()
        self.root.mainloop()


if __name__ == '__main__':
    server = Server('127.0.0.1', 8000)
    server.start()

下面是客户端代码：

import socket
import threading
import tkinter as tk


class Client:
    def __init__(self, ip, port):
        self.ip = ip
        self.port = port
        self.client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

        self.root = tk.Tk()
        self.root.title('Client')
        self.text_recv = tk.Text(self.root, width=50, height=20)
        self.text_recv.pack()
        self.text_send = tk.Text(self.root, width=50, height=5)
        self.text_send.pack()
        self.button_send = tk.Button(self.root, text='Send', command=self.send_message)
        self.button_send.pack()

    def connect_to_server(self):
        try:
            self.client_socket.connect((self.ip, self.port))
            self.text_recv.insert('end', 'Connected to server %s:%s!\n' % (self.ip, self.port))
        except Exception as e:
            self.text_recv.insert('end', 'Failed to connect to server %s:%s!\n' % (self.ip, self.port))
            self.text_recv.insert('end', str(e) + '\n')
            return False
        return True

    def receive_message(self):
        while True:
            recv_data = self.client_socket.recv(1024)
            if not recv_data:
                self.text_recv.insert('end', 'Server %s:%s disconnected!\n' % (self.ip, self.port))
                break
            self.text_recv.insert('end', 'Received message from server: %s\n' % recv_data.decode('utf-8'))

    def send_message(self):
        send_data = self.text_send.get('1.0', 'end')
        self.client_socket.send(send_data.encode('utf-8'))
        self.text_send.delete('1.0', 'end')

    def start(self):
        if not self.connect_to_server():
            return
        threading.Thread(target=self.receive_message).start()
        self.root.mainloop()


if __name__ == '__main__':
    client = Client('127.0.0.1', 8000)
    client.start()

运行服务器端程序，然后运行两个客户端程序，就可以在不同的客户端之间进行聊天了，每个客户端都有一个输入框和一个输出框。
