python 3 'MarkerServer' 对象没有属性 'setsockopt'

Question

我有一个旧的 python 27 代码，我正试图将其移植到 python 35，并且对以下部分有疑问：

class MarkerServer(asyncore.dispatcher):

def __init__(self, queue, proto):

    asyncore.dispatcher.__init__(self)
    self.queue = queue
    if proto.lower() == 'tcp':
        logger.debug('Opening TCP socket.')
        self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
        self.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
        self.setblocking(0)
        self.bind(('', PORT))
        self.listen(5)
    elif proto.lower() == 'udp':
        logger.debug('Opening UDP socket.')
        self.create_socket(socket.AF_INET, socket.SOCK_DGRAM)
        self.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.setblocking(0)
        self.bind(('', PORT))
        handler = MarkerHandler(self, self.queue)
    else:

这将返回以下错误：

    self.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    AttributeError: 'MarkerServer' object has no attribute 'setsockopt'

感谢杰森哈珀的评论。我意识到 python 35 的 asyncore 模块中还有一个更深层次的问题。似乎并非所有方法都已移植并产生错误。修改模块后问题解决

python 3 'MarkerServer' 对象没有属性 'setsockopt'

python 3 'MarkerServer' object has no attribute 'setsockopt'

python-2.7

python-3.x

sockets

setsockopt
