Question

   client.on("joinRoom", function(id) {//this id is roomid user wants to join
      room = new Room(roomid, client.id);
      rooms[roomid] = room;
      client.leave(roomid);//this is users own roomid which he leaves to join other room.
      room.addPerson(client.id);//adding person to the room's people array using his id, not his roomid.
      console.log(rooms[id].people);//list of people in room.
});

这是我的房间

function Room(roomid, owner) {
    this.roomid = roomid;
    this.owner = owner;
    this.people = [];
};
Room.prototype.addPerson = function(personID) {
    this.people.push(personID);
};
module.exports = Room;

但是我在people数组中只有一个用户是userid

[ 'vYDNfK4VPchHFwXQPDiI' ]

为什么它无法将其他人ID推送到数组中。

您正在为每个请求创建一个新房间。在创建之前检查id的房间是否已经存在 -

client.on("joinRoom", function(id) {//this id is roomid user wants to join
      if(!rooms[id]) room[id] = new Room(id, client.id);
      client.leave(id);//this is users own roomid which he leaves to join other room.
      room.addPerson(client.id);//adding person to the room's people array using his id, not his roomid.
      console.log(rooms[id].people);//list of people in room.
});
