tcp server和client代码示例

下面是一个简单的TCP服务器和客户端的代码示例（使用Python的socket模块）：

TCP Server:

import socket

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

# 绑定IP和端口号
server_socket.bind(('localhost', 8000))

# 监听连接
server_socket.listen(1)

print('Server started, waiting for connection...')

# 接受连接请求
client_socket, addr = server_socket.accept()
print(f'Connected by {addr}')

# 接收数据
data = client_socket.recv(1024)
print(f'Received data: {data.decode()}')

# 发送数据
client_socket.sendall('Hello, client!'.encode())

# 关闭连接
client_socket.close()

# 关闭服务器套接字
server_socket.close()

TCP Client:

import socket

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

# 连接服务器
client_socket.connect(('localhost', 8000))

# 发送数据
client_socket.sendall('Hello, server!'.encode())

# 接收数据
data = client_socket.recv(1024)
print(f'Received data: {data.decode()}')

# 关闭连接
client_socket.close()

注意：以上代码示例仅供参考，实际应用中需要根据需求进行修改和完善。
