Redis / Node.js - 2 个客户端（1 个发布/订阅）导致写入问题

尝试创建两个客户端；一种是发布/订阅，另一种是标准连接。这不可能吗？必须有一种方法可以将其抽象为工作:)基本上，如果我做一个get key运行 test.js 后，我看到的只是“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
);

您可能需要从以下位置发布消息client1 since client2专门用于监听某个频道上的消息。关于这种行为的几句话写在节点redis https://github.com/mranney/node_redis readme:

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。
