在多个节点实例中共享 IO 对象 [英] sharing IO object in multiple node instances

问题描述

我想在两个节点实例之间共享由 socket.io 创建的房间，已经使用 redis-store 但无法在不同的节点实例上获取 io.sockets.in(ROOM_ID).emit(MESSAGE,DATA);

I want to share rooms created by socket.io between two node instances, already using redis-store but unable to get io.sockets.in(ROOM_ID).emit(MESSAGE,DATA) on different node instance;

我正在尝试 -实例 A -

I am trying - instance A -

io.set('store',...)

io.on('connection',function(socket){
   socket.join(''room-ABCD);
});

广播一些东西，我可以使用

to broadcst something, I am able to use

io.sockets.in('room-ABCD').emit('event',{data:{}});

但我需要从实例 B 执行类似的广播.

but similar broadcast I need to perform from instance B.

在实例 B io.set('store') 与上面类似，但我不能使用 io.sockets.in('room-ABCD').emit('event',{data:{}})

on instance B io.set('store') is similar to above, but I am not able to use io.sockets.in('room-ABCD').emit('event',{data:{}})

我的理解是-redisStore会把socket+room的信息放到redis里，这样其他进程就可以访问了.[如有错误请指正].现在，我不知道如何在节点的其他进程中识别和获取此信息.

My understanding is - redisStore will put socket+room information in redis so that it is accessible to other process.[please correct if I am wrong]. now, I am not getting how to identify and fetch this information in other process of node.

谢谢.

推荐答案

回答与问题相关的查询 - 一个,两个和这个.

Answering to the queries related to the questions - one,two and this one.

我需要集中注意力的确切点是 - 加入房间.

Exact point where I need to concentrte was - Joinig the room.

我正在使用 client_socket.join("room_name")，但它会将客户端套接字推送到房间.

I was using client_socket.join("room_name"), but it pushes the client socket to the room.

现在，试试io.sockets.socket(client_socket.id).join("room_name").

这会将房间成员推送到 redis，现在它们可以在另一个节点实例中访问.

This pushes the room members to the redis and now they are accessible in another node instance.

进程 B io.sockets.in("room_name").emit("event_name",{data:"1"}) 有效.
