python - 使用 Python 3 进行 Asyncore 数据处理

Question

我正在使用 asynchat 并尝试使用 python3。收到此错误:

    error: uncaptured python exception, closing channel <irc.IRC connected
    at 0x9a5286c> (<class 'AttributeError'>:'str' object has no attribute 
    'more' [/usr/lib/python3.2/asyncore.py|write|89] [/usr/lib/python3.2
    /asyncore.py|handle_write_event|462] [/usr/lib/python3.2asynchat.py|
    handle_write|194] [/usr/lib/python3.2/asynchat.py|initiate_send|245])

我的代码在 Python 2.6.7 上运行良好。

有什么建议吗？

更新:我检查过我确实在使用 python3 的异步聊天。

    ~$ python3
    Python 3.2 (r32:88445, Mar 25 2011, 19:28:28)

    >>> import asynchat
    >>> asynchat
    <module 'asynchat' from '/usr/lib/python3.2/asynchat.py'>
    >>>

根据 http://bugs.python.org/issue12523

Actually, the error is that in Python 3 you should use bytes objects when transmitting/receiving data over the network, not (unicode) strings. That is, replace '\r\n' with b'\r\n', etc.

Of course, the error message should be made less obscure.
