Question: Is it possible to access the origin from setHeaders()?

[elcferreira]

Hallo,

I'm having a problem to setup multiples domain to be Access-Control-Allow-Origin. I don't like to use * because of security issues, so I was trying to apply this solution bellow:

https://stackoverflow.com/questions/24897801/enable-access-control-allow-origin-for-multiple-domains-in-node-js

Is it possible to access the origin on the parameters returned on setHeaders?

setHeaders(res, path, stat) {}

Thank you for all help. ❤️

Solution:

I'm using nuxt, and I tried to do it on

render > setHeaders,

But i switch the logic to serverMiddleware and it works.

Hi @elcferreira sorry you never got a response to your question. I actually swear I remember replying to this question (I guess the same question but somewhere else lol). Anyway, you can access the request object from the response object using res.req. The origin request header would thus be res.req.headers.origin. I know you already have a solution, but just wanted to answer your original one for your reference and anyone else who crosses this issue.

Hey @dougwilson I tried it inside the nuxt.js (v2.15.8) context, but I got undefined.

Hi @elcferreira hm.. I'm not sure exactly what nuxt.js is, as I haven't used it before. This particular module is an Express.js middleware. In Express.js, there is the res.req: https://expressjs.com/en/4x/api.html#res.req
