Question

我一直收到以下错误：

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

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

以下是代码的相关部分

// 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 }) }));

Answer 1

如果你问我，你应该提供更多信息。另外我认为你首先应该删除外部依赖（如MySQL等）。

代码（基于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.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');
