使用带有安全性的nodejs模块快速会话不起作用

Question

I use express-session module with redis connection and nginx proxy. If I use it with secure: false the sid cookie is set. But if I set it to secure it does not. I am set a other cookie directly with express and secure: true and it works.

Express-Session config in Express:

//proxy configuration
app.set('trust proxy', 1); // trust first proxy (ngnix proxy)

//session

app.use(session({
    secret: 'to-secret-to-show',
    resave: false,
    saveUninitialized: true,
    rolling: true,
    cookie: {
        httpOnly: true,
        sameSite: 'strict',
        secure: secure
    },
    store: new RedisSessionStore({
        client: redis,
        ttl: 86400, //time to life, one day
    }),
}));

If secure is set to true or false depents on the envirement. I try to set it directly to true, but does not make a chnage.

nginx proxy settings:

proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        #proxy_set_header X-Forwarded-Host $http_host;

        proxy_pass http://nodejs;
        proxy_redirect off;

When I look at Dokumentation files it should be correct. Do I forgot something? I can not make to heavy test, because I have only my live system with secure connections.

Try adding an X-Forwarded-Proto header:

proxy_set_header X-Forwarded-Proto $scheme;

This is how express-session determines if the connection to nginx was secure.
