io.sockets.emit和广播之间有什么区别？

Question

io.sockets.emit和socket.broadcast.emit有什么区别？广播只是向所有人发出但发送它的套接字吗？

似乎它们可以互换使用：

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
});

Answer 1

io.sockets.emit 将发送给所有客户

socket.broadcast.emit 会将消息发送给除新建连接以外的所有其他客户端
