Socket.io房间的broadcast.to和sockets.in之间的区别

问题描述

Socket.io的自述文件包含以下示例:

Socket.io's readme contains the following example:

    var io = require('socket.io').listen(80);

    io.sockets.on('connection', function (socket) {
      socket.join('justin bieber fans');
      socket.broadcast.to('justin bieber fans').emit('new fan');
      io.sockets.in('rammstein fans').emit('new non-fan');
    });

socket.broadcast.to()和io.sockets.in()有什么区别?

推荐答案

socket.broadcast.to广播到给定房间中的所有套接字，除了广播到io.sockets.in广播时在其上调用的套接字到给定房间中的所有插座上.

socket.broadcast.to broadcasts to all sockets in the given room, except to the socket on which it was called while io.sockets.in broadcasts to all sockets in the given room.
