问题描述
我想让用户创建并加入一个房间",以便他们进行协作.
I would like to have users create and join a "rooms" so that they can collaborate.
我正在查看 SockJs Multiplexer server 并想知道我是否可以利用其中的一些来创建并广播到特定频道/房间.
I'm looking at SockJs Multiplexer server and wondering if I can leverage some of that to create and broadcast to specific channel/room.
In the example, a channel is created manually and client connects to that channel.
将这些频道视为房间有用吗?
Would treating these channels as rooms work?
有没有办法动态创建这些频道,而不是在服务器上手动声明它们?
Is there a way to dynamically create these channels instead of manually declaring them on server?
推荐答案
免责声明:在我写下答案之前,我没有注意到您指的是服务器的 Javascript 版本.因此,我的代码示例是使用基于 Python 的 sockjs-tornado 给出的,但我猜原理应该是一样的.
Disclaimer: I didn't notice that you were referring to the Javascript-version of the server until I had written my answer. Therefore, my code examples are given using the Python-based sockjs-tornado, but I guess the principles should be the same.
是的,您可以通过在每个 SockJSConnection
派生类中保留一组引用连接来将通道视为房间.为此,您只需要从
Yes, you may treat the channels as rooms by keeping a set of referenced connections in each SockJSConnection
-derived class. To do that, all you would need is to change each connection class slightly from
class AnnConnection(SockJSConnection):
def on_open(self, info):
self.send('Ann says hi!!')
def on_message(self, message):
self.broadcast(self.connected, 'Ann nods: ' + message)
到
class AnnConnection(SockJSConnection):
connected = WeakSet()
def on_open(self, info):
self.connected.add(self)
self.send('Ann says hi!!')
def on_message(self, message):
self.broadcast(self.connected, 'Ann nods: ' + message)
def on_close(self):
self.connected.remove(self)
super(AnnConnection, self).on_close()
在 server.py.
为了动态创建通道,我稍微更改了 __main__
代码和 MultiplexConnection
类并添加了几个新类.在 if __name__ == "__main__":
块中,
To create the channels dynamically, I changed the __main__
code and MultiplexConnection
class slightly and added a couple of new classes. In the if __name__ == "__main__":
block,
# Create multiplexer
router = MultiplexConnection.get(ann=AnnConnection, bob=BobConnection,
carl=CarlConnection)
改为
# Create multiplexer
router = MultiplexConnection.get()
虽然
class MultiplexConnection(conn.SockJSConnection):
channels = dict()
# …
def on_message(self, msg):
# …
if chan not in self.channels:
return
在 MultiplexConnection 中已更改
class MultiplexConnection(conn.SockJSConnection):
channels = dict()
_channel_factory = ChannelFactory()
# …
def on_message(self, msg):
# …
if chan not in self.channels:
self.channels[chan] = self._channel_factory(chan)
和课程
class DynamicConnection(SockJSConnection):
def on_open(self, info):
self.connected.add(self)
self.send('{0} says hi!!'.format(self.name))
def on_message(self, message):
self.broadcast(self.connected, '{0} nods: {1}'
.format(self.name, message))
def on_close(self):
self.connected.remove(self)
super(DynamicConnection, self).on_close()
class ChannelFactory(object):
_channels = dict()
def __call__(self, channel_name):
if channel_name not in self._channels:
class Channel(DynamicConnection):
connected = WeakSet()
name = channel_name
self._channels[channel_name] = Channel
return self._channels[channel_name]
已添加到 多路复用.py.
