io.sockets.emit和broadcast有什么区别？

Question

io.sockets.emit和socket.broadcast.emit有什么区别？只是广播向每个人发出但是发送它的套接字吗？

看起来它们可以互换使用:

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 将消息发送到除新创建的连接之外的所有其他客户端

Answer 2

socket.broadcast.emit()行为类似于io.sockets.emit,但不是发射到所有连接的套接字,它将发射到所有连接的套接字,除了它被调用的套接字.因此,在这种情况下,引用的套接字socket将不会收到该事件.

Answer 3

方案:1: -通过使用io.sockets.emit 详细图解:-io.sockets.emit

这里每个Socket获取消息,包括启动器.

  // BY IO>SOCKETS>EMIT
   io.sockets.emit('MyChannelBroadcast',
               {
                 owner:"Anshu Ashish",
                 clientCount:clients,
                 message:"Welcome All"
               }
    );

场景:2: - 通过使用socket.broadcast.emit 详细图表:-socket.broadcast.emit

这里每个套接字都会收到消息,除了一个启动器.

    // BY SOCKET>BROADCAST>EMIT
   socket.broadcast.emit('BroadCastExceptMe',{data:"HAVE A NICE DAY"});

结论: - 现在,完全取决于我们的业务需求,哪一个更受欢迎.
