请用python为这个代码补充一个GUI界面，import time import socket #import tk def main(): ip = "172.20.10.13" port = 8888 other_addr = (ip, port) byte = 1024 udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) while True: send_data = input("发送给客户端:").encode("utf-8") udp_socket.sendto(send_data, other_addr) #输入数据为空退出,否则进入接收状态 if send_data: rev_data, other_addr = udp_socket.recvfrom(byte) localTime = time.asctime(time.localtime(time.time())) print(localTime,"收到来自%s的信息: %s" % (other_addr, rev_data.decode("utf-8"))) else: break udp_socket.close() if __name__ == '__main__': main()

这里是一个简单的GUI界面示例，你可以根据自己的需求进行修改和优化：

import time
import socket
import tkinter as tk

class ChatGUI:
    def __init__(self, master):
        self.master = master
        master.title("Chat")
        
        self.label_ip = tk.Label(master, text="IP:")
        self.label_ip.grid(row=0, column=0, padx=5, pady=5)
        
        self.entry_ip = tk.Entry(master)
        self.entry_ip.grid(row=0, column=1, padx=5, pady=5)
        
        self.label_port = tk.Label(master, text="Port:")
        self.label_port.grid(row=1, column=0, padx=5, pady=5)
        
        self.entry_port = tk.Entry(master)
        self.entry_port.grid(row=1, column=1, padx=5, pady=5)
        
        self.label_send = tk.Label(master, text="Send:")
        self.label_send.grid(row=2, column=0, padx=5, pady=5)
        
        self.entry_send = tk.Entry(master)
        self.entry_send.grid(row=2, column=1, padx=5, pady=5)
        
        self.button_send = tk.Button(master, text="Send", command=self.send_message)
        self.button_send.grid(row=3, column=0, padx=5, pady=5)
        
        self.button_quit = tk.Button(master, text="Quit", command=self.quit)
        self.button_quit.grid(row=3, column=1, padx=5, pady=5)
        
        self.textbox = tk.Text(master)
        self.textbox.grid(row=4, column=0, columnspan=2, padx=5, pady=5)
        
        self.ip = ""
        self.port = 0
        self.other_addr = None
        self.byte = 1024
        self.udp_socket = None
        
    def send_message(self):
        if not self.udp_socket:
            self.ip = self.entry_ip.get()
            self.port = int(self.entry_port.get())
            self.other_addr = (self.ip, self.port)
            self.udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        
        send_data = self.entry_send.get().encode("utf-8")
        self.udp_socket.sendto(send_data, self.other_addr)
        self.textbox.insert(tk.END, "Sent to %s: %s\n" % (self.other_addr, send_data.decode("utf-8")))
        
        rev_data, other_addr = self.udp_socket.recvfrom(self.byte)
        localTime = time.asctime(time.localtime(time.time()))
        self.textbox.insert(tk.END, "%s Received from %s: %s\n" % (localTime, other_addr, rev_data.decode("utf-8")))
        
    def quit(self):
        if self.udp_socket:
            self.udp_socket.close()
        self.master.quit()

if __name__ == "__main__":
    root = tk.Tk()
    gui = ChatGUI(root)
    root.mainloop()

在这个示例中，我们创建了一个名为`ChatGUI`的类，它继承自`tkinter.Tk`类。在`ChatGUI`类的构造函数中，我们创建了界面元素（如标签、文本框、按钮等），并将它们按照网格布局放置在窗口上。

当用户点击“Send”按钮时，我们将获取IP地址、端口号和发送的消息，并使用UDP套接字发送消息。然后，我们等待接收来自对方的回复，并向文本框添加发送和接收消息的日志。当用户点击“Quit”按钮时，我们将关闭UDP套接字并退出应用程序。

你可以在代码中添加一些错误处理程序，以确保应用程序在发生错误时能够正确地恢复。此外，你也可以使用其他的布局管理器（如包装器、网格布局、框架等）来调整界面布局。
