how to list rooms on socket.io nodejs server
提问by pyramation
after progress on the question how to create socket.io multicast groups, I found making rooms a great way to do what I needed.
在如何创建 socket.io 多播组的问题上取得进展后，我发现制作房间是做我需要的事情的好方法。
However, it would be great to know about all the rooms, without an extra data-structure.
但是，如果没有额外的数据结构，了解所有房间会很棒。
Is it possible to get a list of all rooms on the server from the server socket?
是否可以从服务器套接字获取服务器上所有房间的列表？

In a new version of socket.io (1.x), io.sockets.manager.roomswill cause an error. You should use io.sockets.adapter.roomsinstead.
在新版本的 socket.io (1.x) 中，io.sockets.manager.rooms会导致错误。你应该io.sockets.adapter.rooms改用。

As everyone said, in a new version of socket.io (1.x) the rooms can be found at:
正如大家所说，在新版本的 socket.io (1.x) 中，可以在以下位置找到房间：
io.sockets.adapter.rooms
This will return something like:
这将返回如下内容：
{
'qNADgg3CCxESDLm5AAAA': [ 'qNADgg3CCxESDLm5AAAA': true ],
'myRoom': [ 'qNADgg3CCxESDLm5AAAA': true,
'0rCX3v4pufWvQ6uwAAAB': true,
'iH0wJHGh-qKPRd2RAAAC': true ],
'0rCX3v4pufWvQ6uwAAAB': [ '0rCX3v4pufWvQ6uwAAAB': true ],
'iH0wJHGh-qKPRd2RAAAC': [ 'iH0wJHGh-qKPRd2RAAAC': true ]
}
The only room that I want to get is 'myRoom', so I wrote the following function for doing that:
我想要获得的唯一房间是“myRoom”，因此我为此编写了以下函数：
function findRooms() {
var availableRooms = [];
var rooms = io.sockets.adapter.rooms;
if (rooms) {
for (var room in rooms) {
if (!rooms[room].hasOwnProperty(room)) {
availableRooms.push(room);
}
}
}
return availableRooms;
}
This was kind of confusing for me, hope this helps!
这对我来说有点混乱，希望这会有所帮助！

In socketIO version 2.2.0,
在 socketIO 2.2.0 版本中，
io.sockets.managerdoes not exist anymore
io.sockets.manager不再存在
You can get all sockets in a specific room using followings 3.
socket.adapter.rooms;
io.sockets.adapter.rooms
io.sockets.adapter.sids
您可以使用以下3获得特定房间中的所有插座。
socket.adapter.rooms;
io.sockets.adapter.rooms
io.sockets.adapter.sids
If you are using namespace you should use socket.adapter.roomsto get the room lists.
如果您使用命名空间，您应该使用它socket.adapter.rooms来获取房间列表。
{ '/userSocket#oXorUiql1GF68dbTAAAB':
Room {
sockets: { '/userSocket#oXorUiql1GF68dbTAAAB': true },
length: 1
},
roomOneName:
Room {
sockets: { '/userSocket#oXorUiql1GF68dbTAAAB': true },
length: 1
},
roomTwoName:
Room {
sockets: { '/userSocket#oXorUiql1GF68dbTAAAB': true },
length: 1
}
}

and chanced upon this.
并偶然发现了这一点。
in 2.1.0, all the rooms in the server are located in the variable io.sockets.adapter.rooms
在 2.1.0 中，服务器中的所有房间都位于变量io.sockets.adapter.rooms 中
//Use Example//

You will get the following results.

It seems io.of("......").sockets.adapteris undefinedon that version of socket.io. So I used io.adapter.roomsinstead and it works.

I was able to find them using socket._events on an open connection.
我能够在打开的连接上使用 socket._events 找到它们。
io.sockets.on('connection', function(socket){
socket.on('ping', function(data){
console.log(socket._events);
});
});

I don't have enough reputation to post my comment to the original question, but in addition, if you want to list all the rooms in a namespace, it should be coded like this:
我没有足够的声誉来发表我对原始问题的评论，但此外，如果您想列出命名空间中的所有房间，则应将其编码如下：
var nsp = io.of('/my-nsp');
var rooms = nsp.adapter.rooms;
This would help so that if a client join a room by:
这将有助于如果客户通过以下方式加入房间：
socket.join('my-room');
You should be able to see your room name when you do console.log(rooms);
当你这样做时，你应该能够看到你的房间名称 console.log(rooms);
I just want to answer an unanswered comment above as I ran into the same issue after I saw mismatched room names.
我只想回答上面一个未答复的评论，因为我在看到不匹配的房间名称后遇到了同样的问题。
