当套接字被连接时，socketio是否会创建一个房间？(Does socketio creates a room always when a socket gets coonected?)

 我正在创建一个私人聊天应用程序，希望根据他们的兴趣和行为在房间添加特定的套接字，我希望用户随时都可以进入房间。 
 
 我的问题是socket.io是否会在新套接字连接或由于我的代码而发生时自动创建一个房间？ 
 
var allSockets = []; // Adding all new sockets in an array

console.log(allSockets.length); // checking length of an array after socket connection

app.get('/api/rooms',function(req,res){
  res.send(io.sockets.adapter.rooms); // just a url to see the rooms connected
})
 
 以上是代码示例，下面是两个用户连接时的输出示例 
 
{"/#DtUmoNBKeQSYMcepAAAA":{"sockets":{"/#DtUmoNBKeQSYMcepAAAA":true},"length":1},"/#1FXDSOViOj2R64DjAAAB":{"sockets":{"/#1FXDSOViOj2R64DjAAAB":true},"length":1},"57b2ba38426f18d1040a6d5f":{"sockets":{"/#1FXDSOViOj2R64DjAAAB":true,"/#DtUmoNBKeQSYMcepAAAA":true},"length":2}}
 
 我可以在上面的结果中看到，两个用户都有自己的房间以及他们两个在一起的新房间。 所以共有三个房间。 
 
 有没有办法摆脱socketio创建的默认房间，如果有的话。 

I am creating a private chat app want to add specif sockets on rooms based on their interest and behaviours and i want an user to be in a room at any time.
 
My question here is does socket.io automatically create a room whenever a new socket gets connected or it happens because of my code?
 
var allSockets = []; // Adding all new sockets in an array

console.log(allSockets.length); // checking length of an array after socket connection

app.get('/api/rooms',function(req,res){
  res.send(io.sockets.adapter.rooms); // just a url to see the rooms connected
})
 
Above is an example of code and below is an example of output when two users gets connected
 
{"/#DtUmoNBKeQSYMcepAAAA":{"sockets":{"/#DtUmoNBKeQSYMcepAAAA":true},"length":1},"/#1FXDSOViOj2R64DjAAAB":{"sockets":{"/#1FXDSOViOj2R64DjAAAB":true},"length":1},"57b2ba38426f18d1040a6d5f":{"sockets":{"/#1FXDSOViOj2R64DjAAAB":true,"/#DtUmoNBKeQSYMcepAAAA":true},"length":2}}
 
I can see in the above result that two users have their own room as well a new room created by where they both are together. So total of three rooms.
 
Is there any way to get rid of default rooms socketio creates if any.
