webRTC（六）：webrtc信令服务器实现

//给房间所有人回

// io.in(room).emit(‘joined’,room,socket.id);

//除自己所有站点回

// socket.broadcast.emit(‘joined’,room,socket.id)

});

//用户离开

socket.on(‘leave’,(room)=>{

var myRoom = io.sockets.adapter.rooms[room];

var users =(myRoom)?Object.keys(myRoom.sockets).length:0;

//users-1

logger.debug(‘the number of user in room is:’+(users-1));

socket.to(room).emit(‘bye’,room,socket.id);

socket.emit(‘leaved’,room,socket.id);

//给本人回信息

//socket.emit(‘leaved’,room,socket.id);

//给房间除自己以外所有人回

//socket.to(room).emit(‘leaved’,room,socket.id)

//给房间所有人回

//io.in(room).emit(‘leaved’,room,socket.id);

//除自己所有站点回

//socket.broadcast.emit(‘leaved’,room,socket.id)

});
