javascript - 断开 Sockect.io 房间中的所有用户

Question

我一直在尝试根据管理员的意愿断开所有用户与房间的连接。我可以从房间获取 socket ID，但在尝试断开连接或离开房间时出错

这就是我的连接方式:

 var io = require('socket.io'),
    http = require('http'),
    server = http.createServer(),
    io = io.listen(server);

    io.sockets.on('connection', function(socket){
      //socket.join('groupname');
      console.log('User connected');

      socket.on('disconnect', () => {
        console.log('User disconnected...');

      })

//This is how the room is connected to
  socket.on('group', function(groupname) {
         socket.join(groupname);
     });

    socket.on('completed', function(groupname) {
         var users = io.nsps["/"].adapter.rooms[groupname]
              console.log(users)
            for(var i = 0; i < users.length; i++){
               console.log(users[i])///undefined
           }

      });

  })

也试过

 socket.on('completed', function(groupname) {
       var users = io.nsps["/"].adapter.rooms[groupname]
        Object.keys(users.sockets).forEach( function(socketId){
              console.log(groupname+" client socket Id: " + socketId );
              socketId.disconnect();
            });
      });

完成了，特别感谢 tienthanh8490，用于阐明 Socket.io 中的数据管理

我认为我之前所做的，尤其是我的第二个例子是；试图在字符串上触发函数!

总之，这行得通

 socket.on('completed', function(groupname) {
        io.of('/').in(groupname).clients(function(error, clients){
         if (error) throw error;
         for(var i=0; i <clients.length; i++){
            io.sockets.connected[clients[i]].disconnect(true)
         }
       });

这会断开房间中的所有用户
