req.session undefined和req.session.user_id不工作

Question

我使用Express和節點進行會話管理與https。 我想使用express創建一個會話，以便在重定向到公用文件夾中的靜態文件之前進行身份驗證和會話。 以前我遇到了問題麻煩使用express.session和https但是它通過在express.session中包含路徑作為/ public來解決但現在我的req.session顯示為未定義但在瀏覽器中有connect.sid cookie存在

app.js是：

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();
    });

問題是console.log(req.session); 給req.session.user_id = 'xyz';這樣req.session.user_id = 'xyz'; 也沒有工作和錯誤'TypeError: Cannot set property 'user_id' of undefined at /opt/expressjs/app.js:59:24 at callbacks'來自'TypeError: Cannot set property 'user_id' of undefined at /opt/expressjs/app.js:59:24 at callbacks' 。 我經歷了很多問題但卻無法弄明白。

我的網站是靜態的，所有* .html都位於公共目錄中

會話中間件檢查傳入請求是否與cookie路徑匹配; 如果沒有，它不會繼續（並且甚至不會創建req.session ）。 在您的情況下，您的cookie路徑設置為/public/ ，這與請求路徑/login不匹配。

我想你想配置會話中間件cookie以使用/作為路徑：

app.use(express.session({
  cookie: {
    path    : '/',
    httpOnly: false,
    maxAge  : 24*60*60*1000
  },
  secret: '1234567890QWERT'
}));
