An example of an AI chatbot conversation about handling CORS with the Fetch API in JavaScript.
How do I handle CORS issues with the Fetch API in JavaScript?
To handle CORS issues, you can configure your server to include the appropriate CORS headers. This allows your client-side application to make requests to your server.
What headers do I need to set on the server?
You typically need to set the 'Access-Control-Allow-Origin' header to specify which domains are allowed to access your resources.
Can I allow multiple origins?
Yes, you can allow multiple origins by dynamically setting the 'Access-Control-Allow-Origin' header based on the request's origin.
What if I don't control the server?
If you don't control the server, you can use a proxy server to make requests on your behalf, which can help bypass CORS restrictions.
