React + socket.io-无法在用户之间发出消息

如何解决React + socket.io-无法在用户之间发出消息

错误：对于单个用户来说，它工作正常，但是我使用另一个Chrome标签页来加入相同的“房间”，它不显示其他人的消息（好像它们不存在）。 我很确定有一个小错误。

使用上下文API来管理房间和名称的状态。

客户：

io.on('connection',socket => {

    socket.on('join',({ name,room },callback: (params: any) => void) => {
        const data = addUser({ id: socket.id,name,room });
        if (data.error) {
            return callback({ error: data.error })
        }
        socket.join(data.user!.room);

        socket.emit('message',{
            user: 'admin',text: `${data.user!.name} welcome to the chat...`
        });

        io.to(data.user!.room).emit('roomData',{
            room: data.user!.room,users: getUsersInRoom(data.user!.room)
        })
    });

    socket.on('sendMessage',(message,callback: (params: any) => void) => {
        const data = getUser(socket.id);
        if (data.error) {
            return callback({ error: data.error })
        }

        io.to(data.user!.room).emit('message',{
            user: data.user!.name,text: message
        });
    });
});
