可以在
io.nsps[yourNamespace].adapter.rooms[roomName]
这是一个关联数组，键是套接字 ID.在我们的例子中，我们想知道一个房间里的客户数量，所以我们做了 Object.keys(io.nsps[yourNamespace].adapter.rooms[roomName]).length
This is an associative array with keys that are socket ids. In our case, we wanted to know the number of clients in a room, so we did Object.keys(io.nsps[yourNamespace].adapter.rooms[roomName]).length
如果你没有见过/使用过命名空间(比如这个家伙[我])，你可以在这里了解它们http://socket.io/docs/rooms-and-namespaces/ (重要的是:默认命名空间是'/')
In case you haven't seen/used namespaces (like this guy[me]), you can learn about them here http://socket.io/docs/rooms-and-namespaces/ (importantly: the default namespace is '/')
