Python Linux網絡編程實戰案例

在這個實戰案例中，我們將使用Python進行Linux網絡編程

1. 創建一個TCP服務器：

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. 創建一個TCP客戶端：

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()

首先運行服務器代碼，然后運行客戶端代碼。你會看到服務器和客戶端之間的消息傳遞。

3. 創建一個UDP服務器：

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. 創建一個UDP客戶端：

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()

首先運行服務器代碼，然后運行客戶端代碼。你會看到服務器和客戶端之間的消息傳遞。

這些示例展示了如何使用Python進行基本的Linux網絡編程。你可以根據需要修改這些代碼以滿足你的需求。
