How do you handle request and response formats in Symfony APIs?

Answer: In Symfony APIs, request and response formats are handled using the following components:

1. Request Handling: Use the `Request` object to access parameters, headers, and content. You can define the expected data format (e.g., JSON, XML) through content negotiation using the `Accept` header and explicit checks in controller methods.

2. Response Creation: Use the `JsonResponse` or `Response` classes to return data. You can specify the content type and serialize the response data accordingly.

3. Serialization: Utilize the Serializer component to convert objects into arrays or JSON, adapting to the requested format.

4. Routing: Define routes with requirements for the format (e.g., `{_format}`) to further manage how requests are processed based on the requested format.

Overall, Symfony provides robust tools to easily manage request and response formats in APIs.
