Python Linux网络编程实战案例

在这个实战案例中，我们将使用Python进行Linux网络编程

1. 创建一个TCP服务器：

import socket

def main():
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.bind(('localhost', 12345))
    server_socket.listen(5)

    while True:
        client_socket, addr = server_socket.accept()
        print("Connection from", addr)

        data = client_socket.recv(1024)
        print("Received", data)

        client_socket.sendall(b"Hello from the server!")
        client_socket.close()

if __name__ == '__main__':
    main()

2. 创建一个TCP客户端：

import socket

def main():
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client_socket.connect(('localhost', 12345))

    client_socket.sendall(b"Hello from the client!")

    data = client_socket.recv(1024)
    print("Received", data)

    client_socket.close()

if __name__ == '__main__':
    main()

首先运行服务器代码，然后运行客户端代码。你会看到服务器和客户端之间的消息传递。

3. 创建一个UDP服务器：

import socket

def main():
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    server_socket.bind(('localhost', 12345))

    while True:
        data, addr = server_socket.recvfrom(1024)
        print("Received", data, "from", addr)

        server_socket.sendto(b"Hello from the server!", addr)

if __name__ == '__main__':
    main()

4. 创建一个UDP客户端：

import socket

def main():
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

    client_socket.sendto(b"Hello from the client!", ('localhost', 12345))

    data, addr = client_socket.recvfrom(1024)
    print("Received", data, "from", addr)

if __name__ == '__main__':
    main()

首先运行服务器代码，然后运行客户端代码。你会看到服务器和客户端之间的消息传递。

这些示例展示了如何使用Python进行基本的Linux网络编程。你可以根据需要修改这些代码以满足你的需求。
