React CORS issue?

Question

React

Hi everyone, I'm making a get request to api - gallery.dev.webant.ru/api/photos?new=true, but it throws out CORS, I googled it but didn't understand what I need to DO EXACTLY to remove CORS, well, it throws an error (no access to back end)

Answer 1

Is your backend? It is impossible to return origins separated by commas. Either a static address, or give what is in the Origin request header.
If not yours, then make some kind of proxy, either chrome + disable web security or firefox + cors everywhere.

Answer 2

Or, if you're on a LAN, then open Chrome (for example) in unsafe mode.
For windows:
chrome.exe --disable-web-security --user-data-dir="c:/www"
--user-data-dir — folder where Chrome's temporary files will be stored.
If not windows, then everything is here:

And if not Chrome, then I did not take it.
