Node.js NodeJS会话错误

我不断发现以下错误：

        var secured = cookie.secure && (req.connection.encrypted || req.connec

如果你问我的话，你应该提供更多的信息。此外，我认为您应该首先删除外部依赖项（如MySQL等）

错误似乎来自模块代码，而不是您自己的代码。要么模块有一个bug，要么您不知何故没有正确使用它，并且模块没有优雅地报告这个bug。

/**
 * 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>');
