Proxy VIII

完整程式碼

def main():
    if len(sys.argv[1:]) != 5:
        print("Usage: ./proxy.py [localhost] [localport]", end='')
        print("[remotehost] [remoteport] [receive_first]")
        print("Example: ./proxy.py 127.0.0.1 9000 10.12.132.1 9000 True")
        sys.exit(0)
    
    local_host = sys.argv[1]
    local_port = int(sys.argv[2])

    remote_host = sys.argv[3]
    remote_port = int(sys.argv[4])

    receive_first = sys.argv[5]

    if "True" in receive_first:
        receive_first = True
    else:
        receive_first = False

    server_loop(local_host, local_port,
                remote_host, remote_port, receive_first)

if __name__ == '__main__':
    main()

接收一些指令列參數，並開始伺服器迴圈，以便用來聆聽連接。
Take in some command line arguments and then fire up the server loop that listens for connections.
