heroku - socket.io RedisStore 是否适用于 heroku？

Question

我似乎无法让 socket.io RedisStore 在 heroku 上工作。我能够连接到 RedisToGo，但是当我调用 new RedisStore() 时如果我没有向 RedisToGo 连接提供密码，我会得到错误，例如:Error: Ready check failed: ERR operation not permitted

我的配置:

var http = require('http')
  , sio = require('socket.io')
  , _ = require('lodash')
  , port = process.env.PORT || 8000
  , httpServer = http.createServer().listen(port)
  , io = sio.listen(httpServer)
  , RedisStore = sio.RedisStore
  , organization = require('./controllers/organization')
  , chat = require('./controllers/chat')
  , group = require('./controllers/group')
  , util = require('util');

var DEV = false;

if (DEV) {
  var pub = require('redis').createClient()
    , sub = require('redis').createClient()
    , client = require('redis').createClient();
}
else {
  var rtg = require("url").parse(process.env.REDISTOGO_URL);
  var pub = require("redis").createClient(rtg.port, rtg.hostname);
  pub.auth(rtg.auth.split(":")[1], function(err) { console.log('pub ERR: ' + util.inspect(err)); });


  var sub = require("redis").createClient(rtg.port, rtg.hostname);
  sub.auth(rtg.auth.split(":")[1], function(err) { console.log('sub ERR: ' + util.inspect(err)); });

  var client = require("redis").createClient(rtg.port, rtg.hostname);
  client.auth(rtg.auth.split(":")[1], function(err) { console.log('client ERR: ' + util.inspect(err)); });

}


io.configure(function() {
  //create redis connection, set options

  var opts = {host: '127.0.0.1', port: '6379'}
     /******* PROBLEM HERE ******/
    , redisStore = new RedisStore({redisPub: pub,
                                   redisSub: sub,
                                   redisClient: client});


  //io.set('store', redisStore);
  io.set('transports', ['xhr-polling']);
  //io.set('close timeout', 30);
  //io.set('hearbeat timeout', 28);
  //io.set('hearbeat interval', 15);
  io.set("polling duration", 10);
  //io.set('log level', 0);


  if (DEV) {
    require('./lib/dev_static').static(io);
  }
  else {
    require('./lib/prod_static').static(io);
  }

});

io.sockets.on('connection', function(socket) {
  etc ...

});

我没有将 redis 实例与客户端一起传递到 RedisStore。
