在两个套接字服务器之间通信

Question

我在 python 中有两个 TCP 套接字服务器，每个都有一些（大约 4 个）客户端。我希望两台服务器能够相互交谈，以便两者都可以相互发送命令并进行通信。

这可能吗？如果是，怎么做？

Answer 1

这是一个例子：

import socket
socket_between_servers = None


def connect_to(host='', port=1060):
   global socket_between_servers
   sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   try:
      sock.connect((host, port))  #check if the first server is already waiting
      socket_between_servers = sock
   except socket.error:
      s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
      s.bind((host, port))
      s.listen(5)  # waiting for the 4 clients plus the other server
      print 'waiting for the peers...'
      n = 0
      while n < 5:
         sc, sockname = s.accept()
         if sockname == 'ip addresse of the other server':
            socket_between_servers = sc
         n += 1
   else:
      s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
      s.bind((host, port + 1))
      s.listen(4)  # waiting for the 4 clients
      n = 0
      while n < 4:
         sc, sockname = s.accept()

然后与 socket_between_servers 服务器可以通信
