Socket.IO - 如何向房间里的每个人发送事件，包括发件人？ [英] Socket.IO - how to emit event to everybody in the room, including sender?

问题描述

在我的Socket.Io / Node.Js / Express应用程序中 - 在我添加聊天室之前 - 我曾经为每个人（包括发件人）发出这样的事件：

In my Socket.Io / Node.Js / Express app - before I added chat room – I used to emit events like this for everyone (including the sender):

io.emit('chat message', msg);

现在我添加房间并尝试使用

Now I added rooms and try to do the same thing using

socket.broadcast.to(socket.room).emit('chat message', msg);

或

socket.to(socket.room).emit('chat message', msg);

但两者都只发送消息给收件人，但不发送给发件人。

but both only send the message to receivers, but not to the sender.

我应该怎么做才能将此消息发送给发送者，谁也在聊天室？

What should I do so that this message also goes to the sender, who's in the chat room as well?

谢谢！

推荐答案

在这个问题中找到答案：
Socket.io不会向discconect上的房间发送消息

Found an answer in this question: Socket.io Won't Emit messages to rooms on discconect

只需使用

io.sockets.in(socket.room).emit('chat message', msg);
