Express会话无法获取下一个请求的已存储会话值

Question

I'm trying to learn how express session is used. I wrote the following code. When I visit the /session route from Postman, every time it shows following in console:

not set

vikaskumar

What I expect is vikaskumar only, after first request. I guess it is saving this string in session but not storing in memory store. But as per docs, the memory store is default, so it should save it automatically?

Here's the code:

app.use(session({
    secret: 'keyboard cat',
    resave: false,
    saveUninitialized: true
}));

app.use(function (req, res, next) {
    var views = req.session.username;

    if (!views) {
        console.log("not set");
        req.session.username = 'vikaskumar';
    }

    next();
});

app.get("/session", function(req, res){
    console.log(req.session.username);
    res.write(req.session.username);
    res.end();
});

如评论中所述，您需要使用Postman Interceptor的cookie才能与Postman一起使用。
