为什么req.session设置在一条路由中,在另一条路由呼叫中不可用?

标签: node.js express express-session

我使用Express“express”:“~4.13.1”和“express-session”:“^ 1.11.3”。 我已经设置了我的服务器:

app.js:

var express = require('express');
var session = require('express-session');
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var routes = require('./routes/index');
var users = require('./routes/users');
app = express();

// view engine setup
var engines = require('consolidate');
app.set('views', path.join(__dirname, 'views'));
app.engine('html', engines.mustache);
app.set('view engine', 'html');

 // uncomment after placing your favicon in /public
 //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
 app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
      extended: false
 }));
 app.use(cookieParser());
 app.use(express.static(path.join(__dirname, 'public')));

//Using express-session in app with secret key
 app.use(session({
secret: 'mapdcs',
resave: true,
saveUninitialized: true,    
cookie: {
    path: '/',
    httpOnly: true,
    secure: false,
    maxAge: null
}
}));


app.use('/', routes);

app.use('/api/users', users);

index.js:

  // First call
  router.post('/adduser', function(req, res, next) {
    req.session.username = red.body.username;
    req.session.save();
    console.log('>>Session data From Add users');
    console.log(req.session); //I got the username session here
  }
  // Second call
  router.post('/check_auth', function(req, res, next) {
     console.log('>> Session data From check_auth');
     console.log(req.session); //Am not getting session here.
  }

自从过去两天以来我一直试图解决这个问题。请任何人帮忙。提前谢谢。

您似乎错过了右括号')'路由器通话后,我不认为这是主要问题。它与请求没有正确发送响应/终止有关。

如果你将console.log(req.session)更改为发送响应的内容,例如res.json(req.session),则第二个调用有效 - 请参阅下面的示例:

 router.post('/adduser', function(req, res, next) {
   req.session.username = red.body.username;
   req.session.save();
   console.log('>>Session data From Add users');
   // changed console.log to res.json 
   res.json(req.session)
 }); // Added the final closing bracket to router.post

// Second call
  router.post('/check_auth', function(req, res, next) {
     console.log('>> Session data From check_auth');
     // Changed the second console.log to res.json
     res.json(req.session);
  }) // Added another closing bracket

希望这有帮助!

编辑:您也可以使用res.end(),res.send()或res.render() - 生成响应的任何内容 - 请参阅Express response docs

我更改了axios调用,并将withCredential设置为true以解决该问题。
