问题描述

我使用Express和节点通过https进行会话管理。我想使用express创建会话，以便在重定向到公用文件夹中的静态文件之前进行身份验证和会话。以前我遇到了问题使用express.session时遇到问题https://b $ b但是它是通过在express.session中包含路径作为/ public解决，但现在我的req.session显示为未定义，但在浏览器中有connect.sid cookie存在

app.js是：

   c  c   req.session.user_id ='xyz'; 也不起作用，错误 'TypeError：不能设置属性'user_id'未定义在/opt/expressjs/app.js:59:24在callbacks'来了。 
我已经经历了很多问题，但不能弄清楚。 
 
 
 我的网站是静态的，所有的* .html都位于公共目录中解决方案 会话中间件检查传入请求是否匹配cookie路径;如果没有，它不会打扰继续（和 req.session 甚至不会被创建）。在您的情况下，您的Cookie路径设置为 / public / ，与请求路径 / login  。
 
 
 我想你想配置会话中间件cookie使用 / 作为路径：
  app.use（express.session（{
 cookie：{
 path：'/'，
 httpOnly：false，
 maxAge：24 * 60 * 60 * 1000 
}，
 secret：'1234567890QWERT'
}）） 
  
 
I am using Express and node for the session management with https. I want to create a session using express so that authentication and the session is made before the redirection to the static files in the public folder. Previously i was having a problem Trouble using express.session with httpsBut it was solved by including path in the express.session as /public but now my req.session is showing as undefined but in the browser there is connect.sid cookie present
The app.js is :
var express = require('express')TypeError: Cannot set property 'user_id' of undefined at /opt/expressjs/app.js:59:24 at callbacks;
var http = require('http');
var https = require('https');
var fs = require('fs');
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/svgtest1');
var options = {
  key: fs.readFileSync('privatekey.pem'),
  cert: fs.readFileSync('certificate.pem')
};

var app = express();

app.use(express.static(__dirname + '/public'));
app.use(express.urlencoded());
app.use(express.json());
app.use(express.cookieParser());
app.use(express.session({cookie: {  path: '/public/',httpOnly: false , maxAge: 24*60*60*1000}, secret: '1234567890QWERT'}));

//middle ware to check auth
function checkAuth(req, res, next) {
  if (!req.session.user_id) {
    res.send('You are not authorized to view this page');
  } else {
    next();
  }
}


app.get('/', function(req, res) {
  console.log('First page called');
  res.redirect('loginform.html');
  console.log('redirected');
  res.end();
});

app.post('/login', function(req, res) {
  console.log('login called');
  var usrfield = req.body.usrfield;
  var passfield = req.body.passfield;

    console.log(req.session);


// Play with the username and password

        if (usrfield == 'kk' && passfield == '123') {
             req.session.user_id = 'xyz';
        res.redirect('svg-edit.html');
      } else {
        res.send('Bad user/pass');
      }


        console.log(usrfield);
        console.log(passfield);
        res.end();
    });

The problem is that console.log(req.session); gives undefined so the req.session.user_id = 'xyz'; also not works and error 'TypeError: Cannot set property 'user_id' of undefined at /opt/expressjs/app.js:59:24 at callbacks' comes.I have gone through many questions but was not able to figure out. 
My website is static and all the *.html locates in the public directory 
 解决方案 
The session middleware checks if an incoming request matches the cookie path; if not, it doesn't bother continuing (and req.session won't even be created). In your situation, your cookie path is set to /public/, which doesn't match the request path /login.
I think you'd want to configure the session middleware cookie to use / as a path:
app.use(express.session({
  cookie: {
    path    : '/',
    httpOnly: false,
    maxAge  : 24*60*60*1000
  },
  secret: '1234567890QWERT'
}));
