基于TCP的程序设计和基于UDP的程序设计及其过程代码

基于TCP的程序设计过程代码：

客户端：

import socket

# 创建TCP连接
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 8000)
client_socket.connect(server_address)

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

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

# 关闭连接
client_socket.close()

服务器端：

import socket

# 创建TCP连接
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 8000)
server_socket.bind(server_address)
server_socket.listen(1)

while True:
    # 等待客户端连接
    print('Waiting for connection...')
    client_socket, client_address = server_socket.accept()

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

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

    # 关闭连接
    client_socket.close()

基于UDP的程序设计过程代码：

客户端：

import socket

# 创建UDP连接
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
server_address = ('localhost', 8000)

# 发送数据
message = 'Hello, server!'
client_socket.sendto(message.encode(), server_address)

# 接收数据
data, server = client_socket.recvfrom(1024)
print('Received:', data.decode())

# 关闭连接
client_socket.close()

服务器端：

import socket

# 创建UDP连接
server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
server_address = ('localhost', 8000)
server_socket.bind(server_address)

while True:
    # 接收数据
    data, client = server_socket.recvfrom(1024)
    print('Received:', data.decode())

    # 发送数据
    message = 'Hello, client!'
    server_socket.sendto(message.encode(), client)

以上代码仅为示例，实际应用程序中需要根据具体需求进行修改。
