Question

在Socket.io 1.0和Socket.io 0.9中，将一条消息广播到一个房间内所有连接的套接字，以下哪种语法是正确的？

以下都没有向我的客户端Web控制台发送消息，该控制台有一个简单的日志声明，但至少有四个正在发送给其他客户端。

如何正确地将“joined_channel”消息发送回我的已连接客户端以及会议室中的所有其他客户端？

Client

 socket.on('joined_channel', function(data){
    console.log('joined channel', data);    
})


 Server

 // this is for 0.9
      io.sockets.in(data.room).emit('joined_channel', data.room);

 // which version is this for? Any?
      socket.broadcast.to(data.room).emit('joined_channel', data.room);

 // is this to all connected users?
      io.sockets.emit('joined_channel', data.room);

 // To all connected users globally?
      io.emit('joined_channel', data.room);

 // how is socket different than io?
      socket.emit('joined_channel', data.room);

 // this is for 0.9 but does it work at all?
      io.sockets.to(data.room).emit('joined_channel', data.room);

 // this is as above but 1.0?
      io.to(data.room).emit('joined_channel', data.room);

这是最新的socket.io。

取自http://psitsmike.com/2011/10/node-js-and-socket-io-multiroom-chat-tutorial/

//emit from server to everyone but the clients socket
socket.broadcast.emit('joined_channel', data);

//broadcast information to a certain room only (excluding the client)
socket.broadcast.to( data.room ).emit('joined_channel');

//broadcast information globally to a certain room
io.sockets.in( data.room ).emit('joined_channel');

Socket.io 0.9和1.0向所有会员广播
