Socket.IO - 如何获取连接的套接字/客户端列表? [英] Socket.IO - how do I get a list of connected sockets/clients?

问题描述

我正在尝试获取当前连接的所有套接字/客户端的列表.

I'm trying to get a list of all the sockets/clients that are currently connected.

io.sockets 不返回数组.

我知道我可以使用数组保留我自己的列表，但不要认为这是最佳解决方案，原因有两个:

I know I could keep my own list using an array, but don't think this is an optimal solution for 2 reasons:

1. 冗余.Socket.IO 已保留此列表的副本.

1. Redundancy. Socket.IO already keeps a copy of this list.

Socket.IO 提供了为客户端设置任意字段值的方法(即:socket.set('nickname', 'superman'))所以我需要跟上如果我要维护我自己的列表，这些变化就会发生.

Socket.IO provides method to set arbitrary field values for clients (i.e: socket.set('nickname', 'superman')) so I'd need to keep up with these changes if I were to maintain my own list.

帮助?

推荐答案

在 Socket.IO 0.7 中，您在命名空间上有一个 clients 方法，它返回所有连接的套接字的数组.

In Socket.IO 0.7 you have a clients method on the namespaces, this returns a array of all connected sockets.

无命名空间的 API:

API for no namespace:

var clients = io.sockets.clients();
var clients = io.sockets.clients('room'); // all users from room `room`

对于命名空间

var clients = io.of('/chat').clients();
var clients = io.of('/chat').clients('room'); // all users from room `room`
