我正在用Python编写一个telnet服务器,它是一个内容服务器。用户可以通过telnet连接到该服务器,并呈现文本内容。
我的问题是,这个服务器显然需要支持多个同时连接。当前我现在拥有的实现仅支持一个连接。
这是我最初开始的基本概念验证服务器(尽管程序随着时间的推移发生了很大变化,但基本的telnet框架没有改变):
import socket, os
class Server:
def __init__(self):
self.host, self.port = 'localhost', 50000
self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.socket.bind((self.host, self.port))
def send(self, msg):
if type(msg) == str: self.conn.send(msg + end)
elif type(msg) == list or tuple: self.conn.send('\n'.join(msg) + end)
def recv(self):
self.conn.recv(4096).strip()
def exit(self):
self.send('Disconnecting you...'); self.conn.close(); self.run()
# closing a connection, opening a new one
# main runtime
def run(self):
self.socket.listen(1)
self.conn, self.addr = self.socket.accept()
# there would be more activity here
# i.e.: sending things to the connection we just made
S = Server()
S.run()
谢谢你的帮助。
