Redis/Node.js - 2个客户端(1个pub/sub)导致写入问题

Question

试图创建两个客户端; 一个是pub/sub,另一个是标准连接.这不可能吗？必须有一种方法来抽象这个工作:)基本上,如果我get key在运行test.js后做了,我所看到的只是'valueBefore'.输出:

node test.js

代码:

var redis = require('redis');

var client1 = redis.createClient();
var client2 = redis.createClient();

client2.on('message', function (channel, message) {
    console.log('Received a message on channel: ' + channel);       

    client1.set('key', message, redis.print);

});

client2.subscribe('channel');

client1.set('key', 'valueBefore', redis.print);

setTimeout(
    function() {
        client2.publish('channel', 'valueAfter');
    },3000
);

您可能需要发布消息,client1因为client2它专门用于侦听某些频道上的消息.有关此行为的几句话都写在node_redis自述文件中:

如果您需要在发布/订阅模式下向Redis发送常规命令,只需打开另一个连接即可.
