CORS Policy Blocked

[KerolosYoussef]

'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Hello, I got this error message and i think you didn't enable the CORS in your server.

You cannot call the service directly
You can use SSR

By port 4200 I guess you are using Angular :D you can set up a proxy in Angular so that you won't get CORS errors and still contact the API.
