I wrote the below code

    def _read_args():
        type_byte = stream.peek(1)
        if (type_byte == '\x11'):
            if (not decoder.use_amf3):
                raise pyamf.DecodeError('Unexpected    AMF3    type    with    incorrect    message    type')
            return decoder.readElement()
        if (type_byte != '\n'):
            raise pyamf.DecodeError('Array    type    required    for    request    body')
        stream.read(1)
        x = stream.read_ulong()
        return [decoder.readElement() for i in xrange(x)]
    target = stream.read_utf8_string(stream.read_ushort())
    response = stream.read_utf8_string(stream.read_ushort())
    status = STATUS_OK
    is_request = True
    for (code, s) in STATUS_CODES.iteritems():
        if (not target.endswith(s)):
            continue
        is_request = False
        status = code
        target = target[:(0 - len(s))]
    if logger:
        logger.debug(('Remoting    target:    %r' % (target,)))
    data_len = stream.read_ulong()
    pos = stream.tell()
    if is_request:
        data = _read_args()
    else:
        data = decoder.readElement()
    if (strict and ((pos + data_len) != stream.tell())):
        raise pyamf.DecodeError(('Data    read    from    stream    does    not    match    body    length    (%d    !=    %d)' % ((pos + data_len), stream.tell())))
    if is_request:
        return (response, Request(target, body=data))
    if ((status == STATUS_ERROR) and isinstance(data, pyamf.ASObject)):
        data = get_fault(data)
    return (target, Response(data, status))
