會話的NodeJS錯誤

Question

我不斷收到以下錯誤：

/usr/local/lib/node/.npm/connect/1.6.0/package/lib/middleware/session.js:263 
     var secured = cookie.secure && (req.connection.encrypted || req.connec 
          ^*emphasized text*

    at Query._handlePacket (/usr/local/lib/node/.npm/mysql/0.9.1/package/lib/mysql/query.js:53:14) 

下面是代碼

// require express, mysql, and our very own db library 
var express = require("express"); 
mysqlD = require("mysql").Client; 
mysql = new mysqlD(); 
MemoryStore = require('connect').session.MemoryStore; 

var app = express.createServer(); 
app.use(express.bodyParser()); 
app.use(express.cookieParser()); 
app.use(express.session({ secret: "hey you", store: new MemoryStore({ reapInterval: 60000 * 10 }) }));

，如果你問我，你應該提供方式的詳細信息的相關部分。另外我認爲你應該首先需要刪除外部依賴（如MySQL等）。

代碼（基於https://raw.github.com/visionmedia/express/master/examples/session/app.js）

/** 
* Module dependencies. 
*/ 
var express  = require('express'), 
    MemoryStore = require('express').session.MemoryStore; 

var app = express.createServer(
    express.logger(), 

    // Required by session() middleware 
    express.cookieParser(), 

    // Populates: 
    // - req.session 
    // - req.sessionStore 
    // - req.sessionID (or req.session.id) 
    express.session({ secret: 'keyboard cat', store: new MemoryStore({ reapInterval: 60000 * 10 })}) 
); 

app.get('/', function(req, res){ 
    var body = ''; 
    if (req.session.views) { 
    ++req.session.views; 
    } else { 
    req.session.views = 1; 
    body += '<p>First time visiting? view this page in several browsers :)</p>'; 
    } 
    res.send(body + '<p>viewed <strong>' + req.session.views + '</strong> times.</p>'); 
}); 

app.listen(3000, '127.0.0.1'); 
console.log('Express app started on port 3000');
