io.sockets.emit和广播之间有什么区别? [英] What's the difference between io.sockets.emit and broadcast?

问题描述

io.sockets.emit和socket.broadcast.emit有什么区别?仅仅是广播向所有人发出了发送广播的套接字吗?

What's the difference between io.sockets.emit and socket.broadcast.emit? Is it only that broadcast emits to everyone BUT the socket that sends it?

它们似乎可以互换使用:

It seems like they can be used interchangeably:

io.sockets.on('connection', function (socket) {
  //these should do the same thing  
  io.sockets.emit('this', { receivers: 'everyone'});

  socket.broadcast.emit('this', { receivers: 'everyone but socket'}); //emits to everyone but socket
  socket.emit('this', { receivers: 'socket'}); //emits to socket
});

推荐答案

io.sockets.emit将发送给所有客户端

socket.broadcast.emit会将消息发送给除新创建的连接以外的所有其他客户端

socket.broadcast.emit will send the message to all the other clients except the newly created connection
