Magento 2.4 and CORS

[alexandred8025]

hello, I am using magento 2.4, the application must call a webservice with XMLHTTPRequest, with javascript, the error that appears is: Access to XMLHttpRequest at '***' from origin '***' has been blocked by CORS policy : Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

So I looked on the forums, I modified the file:
/etc/apache2/apache2.conf
In order to add:
<Directory / var / www / html>
Order Allow, Deny
Allow from all
AllowOverride all
Header set Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Methods "GET, POST, OPTIONS, DELETE"
</Directory>

unfortunately that does not solve my concern, would you have any leads I could use please?

Hello @alexandred8025 

I guess you can resolve this issue by adding this in your .htaccess :

Header add Access-Control-Allow-Origin "b.com"

This will allow the resources to load on the second domain. If you would prefer to allow the resources to load on all domains you can use :

Header add Access-Control-Allow-Origin "*" 

Hope it works !

Thanks but it doesn't work, I put it in the .htaccess in:
/var/www/html/.htaccess
The error remains the same in the console.
Do you have another lead please?

The .htaccess file is in root folder of your Magento Project, just change in :
var/www/html/MAGENTO_PROJECT/.htaccess

Let me know if it works !

[alexandred8025]

Yes, it's root folder in var/www/html

Doesn't work for me in .htaccess

Hmmmm, I don't know why, I've been on it for 3 days
