Fetch Instagram profile on search based

Question

I want to fetch profile data by username-based search using ajax. I am getting cors error

Access to XMLHttpRequest at 'https://www.instagram.com/username?__a=1' from origin 'http://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

I searched a lot add headers allow "Access-Control-Allow-Origin":"*" but not works.

what is wrong and how can i fix it?

Answer 1

The access control header has to be put on the server, not on the client. If you don't control the server, there's nothing you can do about this.
