NodeJS express-session req.session未定义

Question

我正在开发一个简单的登录系统,但似乎没有保存会话

我已经制作了一个简单的测试代码,谁能告诉我它有什么问题？我正在运行登录,之后我正在运行is_logged但是我从未登录,并且两个会话都是未定义的

var port = process.env.PORT || 8080;
var express = require('express');
var app = express();


var cookieParser = require('cookie-parser');
var session = require('express-session');



app.use(cookieParser());
app.use(session({
    secret: "fd34s@!@dfa453f3DF#$D&W", 
    resave: false, 
    saveUninitialized: true, 
    cookie: { secure: true }
}));



 app.post('/test_login', function(req, res){

    req.session.users_schema = 1;
    req.session.user_doc = 2;

    res.json({"first": req.session.users_schema, "second": req.session.user_doc});
});
 app.post('/test_is_loggin', function(req, res){

    if( !req.session.users_schema || !req.session.user_doc ) { 

        console.log("no");
        res.json({"first": 1, "second": 1});
    }
    else {

        console.log("no2");
        res.json({"first": req.session.users_schema, "second": req.session.user_doc});
    }

 });


app.listen(port);
console.log('Listening on port ' + port);

Answer 1

这是因为选择 cookie.secure = true

引用

请注意,secure:true是推荐选项.但是,它需要启用https的网站,即安全cookie需要HTTPS.

请参阅https://github.com/expressjs/session#cookie-options

您必须将其设置为false,以允许非https主机上的会话cookie,或使用https主机.

测试代码

var port = process.env.PORT || 8080;
var express = require('express');
var app = express();


var cookieParser = require('cookie-parser');
var session = require('express-session');



app.use(cookieParser());
app.use(session({
    secret: "fd34s@!@dfa453f3DF#$D&W",
    resave: false,
    saveUninitialized: true,
    cookie: { secure: !true }
}));



 app.get('/test_login', function(req, res){

    req.session.users_schema = 1;
    req.session.user_doc = 2;

    res.json({"first": req.session.users_schema, "second": req.session.user_doc});
});
app.get('/test_is_loggin', function(req, res){

  if( !req.session.users_schema || !req.session.user_doc ) {

      console.log("no");
      res.json({"first": 1, "second": 1});
  }
  else {

      console.log("OK");
      res.json({"first": req.session.users_schema, "second": req.session.user_doc});
  }

});


app.listen(port);
console.log('Listening on port ' + port);

[mh-cbon@pc15 test] $ node express-session.js 
Listening on port 8080
OK
