如何使用strophe在openfire中创建持久的房间？

var connection = new Strophe.Connection("http://your_openfire_server:7070/http-bind/");

connection.connect("your_jid", "your_password", function(status) {
  if (status === Strophe.Status.CONNECTED) {
    // 连接成功，可以执行后续操作
  }
});

var roomJid = "room_name@conference.your_openfire_server";
var room = connection.muc.createInstantRoom(roomJid);

room.configure({
  roomname: "Room Name",
  muc#roomconfig_persistentroom: "1",
  muc#roomconfig_roomdesc: "Room Description"
});

room.save();
