Question

我是Express会议的新手，并希望我可以使用快速会话传递变量。

基本上我使用护照来允许GitHub登录，我可以使用req.user获取用户的信息。当用户通过GitHub登录时，我想将用户重定向到登录页面，该页面会要求用户在创建帐户之前验证信息，或者如果帐户已经存在，则会显示欢迎页面。

let app = express();
app.use(session({secret: "blahblahblah"}));

console.log('github authenticated');
let sess = req.session;
//I want to pass the req.user(returned from GitHub) to a variable sess.user
sess.user = req.user; 
console.log(sess.user); //shows correct info    
res.redirect('/user/login');

module.exports = app;

然而，当我尝试从我的路线访问req.session时，它返回'undefined'：

let session = require('express-session');
let app = express();

app.use(session({secret: "blahblahblah"}));
app.use(router);

router.get('/login', function(req, res, next) {
    let sess = req.session;
    console.log(sess.user); //undefined
    //would check the database
    //if user doesn't already exists pre-populate fields
    //render appropriate page
  });

您应该在请求对象本身传递数据

let sess = req.session;
sess.user = req.user;
req.mysess=sess.user //pass like this


router.get('/login', function(req, res, next) {
let sess = req.mysess;
console.log(sess);
  });

在Express中的会话中传递变量信息
