python - 使用 pexpect 从 virtualbox 监听端口

Question

我正在尝试在 python 中创建一个 tcplistener(必要时使用 pexpect)以在 Windows xp 主机上的 virtualbox 中监听来自 Ubuntu 的 tcp 连接。如果你们中的任何一位能指出正确的方向，我将不胜感激。谢谢。

P.S:我在该领域的经验有限，欢迎任何帮助。

Python 已经在标准库中提供了一个简单的套接字服务器，它被恰本地命名为SocketServer。 .如果你想要的只是一个基本的监听器，看看这个 example straight from the documentation :

import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler):
    """
    The RequestHandler class for our server.

    It is instantiated once per connection to the server, and must
    override the handle() method to implement communication to the
    client.
    """

    def handle(self):
        # self.request is the TCP socket connected to the client
        self.data = self.request.recv(1024).strip()
        print "%s wrote:" % self.client_address[0]
        print self.data
        # just send back the same data, but upper-cased
        self.request.send(self.data.upper())

if __name__ == "__main__":
    HOST, PORT = "localhost", 9999

    # Create the server, binding to localhost on port 9999
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)

    # Activate the server; this will keep running until you
    # interrupt the program with Ctrl-C
    server.serve_forever()
