我正在通过redis将storm连接到javascript。redis部分工作得很好，但是当我尝试发布元组（真正的字符串）时，我的代码（来自internet的一个例子只是稍微修改了一下）没有收到任何东西，redis也能很好地接收元组。这是我的密码：

/*
    Node.js server script
    Required node packages: express, redis, socket.io

* /

const PORT = 3000;
const HOST = 'localhost';

var express = require('express'),
    http = require('http'), 
    server = http.createServer(app);
    log('info', 'connected to express');
var app = express();

const redis = require('redis');
const client = redis.createClient();
log('info', 'connected to redis server');

const io = require('socket.io');

if (!module.parent) {
    server.listen(PORT, HOST);
    const socket  = io.listen(server);

    socket.on('connection', function(client) {
        const subscribe = redis.createClient()
        subscribe.subscribe('realtime');

        subscribe.on("message", function(channel, message) {
            client.send(message);
            log('msg', "received from channel #" + channel + " : " + message);
        });

        client.on('message', function(msg) {
            log('debug', msg);
        });

        client.on('disconnect', function() {
            log('warn', 'disconnecting from redis');
            subscribe.quit();
        });
    });
}

function log(type, msg) {

    var color   = '\u001b[0m',
        reset = '\u001b[0m';

    switch(type) {
        case "info":
            color = '\u001b[36m';
            break;
        case "warn":
            color = '\u001b[33m';
            break;
        case "error":
            color = '\u001b[31m';
            break;
        case "msg":
            color = '\u001b[34m';
            break;
        default:
            color = '\u001b[0m'
    }

    console.log(color + '   ' + type + '  - ' + reset + msg);
}

当我发送int时，它会将消息发送到终端，但不是用元组。我只是一个javascript迷，我不明白为什么它不能像int一样读取元组。
提前谢谢
