研究方向

The issue is about missing CORS headers when making requests from a browser to an Android server. Research how AndServer handles HTTP responses (likely in the server configuration or handler classes). Look for existing CORS support or filters. If none, implement a mechanism to add 'Access Control Allow Origin' header to responses. Check the maintainer's comments for guidance on preferred implementation.
