python实现增删好友的功能 ，客户端与服务器端，基于TK界面设计

下面是一个基于Tkinter界面设计的客户端和服务器端实现增删好友功能的示例代码：

服务器端代码：

import socket
import threading

# 创建TCP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定地址和端口号
server_address = ('localhost', 8888)
server_socket.bind(server_address)

# 设置监听队列大小
server_socket.listen(5)

# 存储好友列表
friends = {}

# 处理客户端请求的函数
def handle_client(client_socket, client_address):
    print("客户端 {} 已连接".format(client_address))
    while True:
        # 接收客户端发送的数据
        data = client_socket.recv(1024).decode('utf-8')
        if not data:
            print("客户端 {} 已断开".format(client_address))
            break
        # 解析客户端发送的命令
        cmd, *args = data.split()
        if cmd == "add":
            name, phone = args
            friends[name] = phone
            client_socket.sendall("已成功添加好友：{}，电话号码为：{}".format(name, phone).encode('utf-8'))
        elif cmd == "delete":
            name = args[0]
            if name in friends:
                del friends[name]
                client_socket.sendall("已成功删除好友：{}".format(name).encode('utf-8'))
            else:
                client_socket.sendall("该好友不存在".encode('utf-8'))
        else:
            client_socket.sendall("无效的命令".encode('utf-8'))
    # 关闭客户端套接字
    client_socket.close()

# 监听客户端连接请求
while True:
    print("等待客户端连接...")
    # 接受客户端连接请求
    client_socket, client_address = server_socket.accept()
    # 创建新线程来处理客户端请求
    client_thread = threading.Thread(target=handle_client, args=(client_socket, client_address))
    client_thread.start()

客户端代码：

import socket
import tkinter as tk

# 创建TCP套接字
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接服务器
server_address = ('localhost', 8888)
client_socket.connect(server_address)

# 创建主窗口
window = tk.Tk()
window.title("好友管理系统")
window.geometry("300x200")

# 创建标签和文本框
name_label = tk.Label(window, text="姓名：")
name_label.grid(row=0, column=0)
name_entry = tk.Entry(window)
name_entry.grid(row=0, column=1)

phone_label = tk.Label(window, text="电话：")
phone_label.grid(row=1, column=0)
phone_entry = tk.Entry(window)
phone_entry.grid(row=1, column=1)

# 定义添加好友函数
def add_friend():
    name = name_entry.get().strip()
    phone = phone_entry.get().strip()
    if name and phone:
        # 发送添加好友命令给服务器
        cmd = "add {} {}\n".format(name, phone)
        client_socket.sendall(cmd.encode('utf-8'))
        # 接收服务器的回复并显示在消息框中
        response = client_socket.recv(1024).decode('utf-8')
        message_box.insert(tk.END, response + "\n")
    else:
        message_box.insert(tk.END, "姓名和电话不能为空\n")

# 定义删除好友函数
def delete_friend():
    name = name_entry.get().strip()
    if name:
        # 发送删除好友命令给服务器
        cmd = "delete {}\n".format(name)
        client_socket.sendall(cmd.encode('utf-8'))
        # 接收服务器的回复并显示在消息框中
        response = client_socket.recv(1024).decode('utf-8')
        message_box.insert(tk.END, response + "\n")
    else:
        message_box.insert(tk.END, "姓名不能为空\n")

# 创建按钮
add_button = tk.Button(window, text="添加好友", command=add_friend)
add_button.grid(row=2, column=0)

delete_button = tk.Button(window, text="删除好友", command=delete_friend)
delete_button.grid(row=2, column=1)

# 创建消息框
message_box = tk.Text(window)
message_box.grid(row=3, column=0, columnspan=2)

# 进入主循环
window.mainloop()

该程序中，服务器端使用一个字典来存储好友列表，当收到客户端发送的添加好友或删除好友命令时，服务器端会解析命令并对字典进行相应的操作，然后将操作结果发送回客户端。客户端使用Tkinter来创建一个简单的用户界面，当用户点击添加好友或删除好友按钮时，客户端会将命令发送给服务器，并显示服务器的回复结果。
