服务器端口配置丢失？

Question

我正在尝试使Autobahn示例在使用Python 3.3和asyncio 0.4.1的虚拟环境下工作，但Chrome始终显示1006。

发现调试选项（factory.debug = True）之后，我遇到了以下服务器输出：

[('debug', True, 'WebSocketServerFactory'),

如果在示例中将端口显式设置为9000，该端口如何设置为None？

Answer 1

UUPS。 我们最近合并了一个补丁，该补丁允许在不提供WebSocket URL的情况下定义工厂，调整了示例，但没有发布到PyPi。 抱歉。

我现在才发布（0.8.6）。 因此，您可以：

pip install -U autobahn

或将示例代码更改为

factory = WebSocketServerFactory("ws://localhost:9000")

再次抱歉 ..
