A simple script that helps bypass CORS restrictions
A simple script that helps bypass CORS restrictions.
By default, it doesn't apply to any websites. In order for this script to take effect on a site, you need to add the website to this script's User matches list. (You can find it at Dashboard - Installed Userscripts - CORS Helper - Settings - Includes/Excludes - User matches - Add...)
After this, refresh the page and you'll have access to GM_fetch function under the window object, which behaves like fetch but without CORS restrictions.
// ...
// @require https://cdn.jsdelivr.net/npm/@trim21/gm-fetch@0.1.15
// ...
unsafeWindow.GM_fetch = GM_fetch;
Yes, that's it. It simply exposes the GM_fetch function under window.
Please only enable this script on websites you trust, otherwise you're on your own.
Trim21/gm-fetch, for providing wrappers for GM.xmlHttpRequest that are compatible with fetch.
