重新加入房间时，套接字io重复消息

Question

我正在用io套接字编写一个聊天应用程序，但是当我重新加入剩下的房间时，我陷入了一个问题，我发送的消息被重复了，发送了（n次），我在Google上搜索了很多，但是却一无所获，我第一次加入任何房间都可以，但是当我离开并再次加入时，会出现问题

这是客户端（reactjs）

error: ‘comphelper::FlagRestorationGuard’ has a field ‘comphelper::FlagRestorationGuard::<anonymous>’ whose type uses the anonymous namespace [-Werror=subobject-linkage]
     class FlagRestorationGuard
           ^~~~~~~~~~~~~~~~~~~~

这是服务器（nodejs）

// Log Messages to the console
  this.socket.on("send-msg", info => {
    console.log(info.msg);
  });

  joinRoomOne = () => {
    this.socket.emit("join-room", { roomName: "room1" });
  };

  logMsgToRoomOne = () => {
    this.socket.emit("send-msg", {
      msg: "Hello World From Room One",
      roomName: "room1"
    });
  };

  joinRoomTwo = () => {
    this.socket.emit("join-room", { roomName: "room2" });
  };

  logMsgToRoomTwo = () => {
    this.socket.emit("send-msg", {
      msg: "Hello World From Room Two",
      roomName: "room2"
    });
  };

  leaveRooms = () => {
    this.socket.emit("leave-rooms");
  };
