listener.py

一个java写的proxy的例子

from proxy4_base import *

class Listener(asyncore.dispatcher):
    def __init__(self, port, Handler):
        asyncore.dispatcher.__init__(self)
        self.addr = (('', 'localhost')[ProxyConfig.local_sockets_only], port) #
        self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
        self.set_reuse_addr()
        self.bind(self.addr)
        self.listen(5)

        self.Handler = Handler

    def __repr__(self):
        return '<Listener:%s>' % self.addr[1]
    
    def log(self, msg):
        pass

    def fileno(self):
        return self._fileno
    
    def writable(self):
        return 0
    
    def handle_accept(self):
        message(None, 'accept', None, None, self)
        apply(self.Handler, self.accept())

    def handle_error(self, type, value, tb=None):
        message(1, 'error', None, None, self, type, value)
        import traceback
        if tb: traceback.print_tb(tb)
