Node.js表示登录cookie和URL

Question

I am quite new to Node.js and I have two problems I cannot seem to be able to solve nor find any solutions on the internet.

1. If I want to create a login function (I have everything setup already except the cookies part) I have to somehow get the servers response, set a cookie and send it (express).

Now I'm wondering how should I get into this to use the variable in the login function?

The login function accepts callback, request, response as parameters. I wanted to return a callback whether the cookie is set after setting it. But the problem occurs when I want to set the cookie. I have to use response.send() which results in an infinite loop.

2. Is it possible to visit for example localhost/mywebsite and still get the server to work instead of localhost:8080 ? (8080 is port I'm listening to, as an example)

Answer 1

This is a wonderful guide on setting up authentication in Express using a tried-and-true authentication library called Passport . And here is a second guide using an enterprise-grade (there's a free version) library from Auth0 and it has a lot more features regarding identity.

Update
So once the user logs in, you could send a cookie like this: res.cookie(cookieObject).send(responseObject) - more on this here . It would then be the browser/client-side framework's responsibility to return the cookie with every request. You could use the cookieparser package from NPM to help parse cookies from the req object. Let us know if this helps.
