VisualizaçõesExpress/axios don't set cookies and headers for response
I have very complicated problem. My project has 2 API's. 1 API is for front-end of my application and 1 is for back-end. How it works, is just I send request from front-end API to back-end API.
Front-end API has URL http://localhost:8080/api/ and back-end API has URL http://localhost:3000.
The problem is front-end API can't get cookies from back-end API.
Here is example, function of front-end API just send request to back-end:
router.get('/test-front-api', async (req, res) => {
const data = await api.get('/test-back-api')
return res.json(data.data)
})
Back-and just sends cookie and some random text:
router.get("/test-back-api", (req, res) => {
res.cookie("test", "cookie")
res.send("Hi from back-end")
})
A here is where I have problem:
router.get('/test-front-api', async (req, res) => {
const data = await api.get('/test-back-api')
console.log(data.headers) // If you do console.log here you will this cookie test
return res.json(data.data)
})
But this cookie is not set in browser.
Let me show one more example. In browser I can just type http://localhost:8080/api/test-front-api and here is result, no cookie:
But, if I type not front-end API endpoint, but back-end, everything works perfect:
I was trying literally everything I found about cors options, axios {withCredentials: true} etc. Nothing works.
I have found one solution, but I don't like it:
router.get('/test-front-api', async (req, res) => {
const data = await api.get('/test-back-api')
// Something like this
res.cookie("test", JSON.stringify(data.headers['set-cookie']))
return res.json(data.data)
})
So, my question is why cookie is no set by front-end endpoint?

I have found not reason of the problem, but solution that seems to be ok. As I said, there are 2 API's - front-end and back-end.
From back-end API I get this cookie, but actually, it makes no sense to send it in header. Why? Because the front-end API will send it back on front.
So, using example above, you can do this, first, just send this cookies in body:
router.get("/test-back-api", (req, res) => {
res.json({cookie: "cookie"})
res.send("Hi from back-end")
})
And then, in front-end API, handle it:
router.get('/test-front-api', async (req, res) => {
const data = await api.get('/test-back-api')
res.cookie("test", data.cookie)
return res.json(data.data)
})
But I still have no idea, why I can send the same headers twice, through back-end API, then front-end API and finally on front.
