linux使用socket代理

import socket
import threading

def handle_client(client_socket):
    target_host = "www.example.com"
    target_port = 80

    # 连接目标服务器
    target_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    target_socket.connect((target_host, target_port))

    while True:
        # 接收客户端数据并转发给目标服务器
        client_data = client_socket.recv(4096)
        if not client_data:
            break
        target_socket.send(client_data)

        # 接收目标服务器数据并转发给客户端
        target_data = target_socket.recv(4096)
        if not target_data:
            break
        client_socket.send(target_data)

    client_socket.close()
    target_socket.close()

def main():
    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.bind(('0.0.0.0', 8080))
    server.listen(5)
    print("代理服务器启动，监听端口8080...")

    while True:
        client_sock, addr = server.accept()
        print(f"接收到来自{addr}的连接")
        client_handler = threading.Thread(target=handle_client, args=(client_sock,))
        client_handler.start()

if __name__ == "__main__":
    main()
