Setting XML content type in raw response

[gizmo-rt]

Currently working on a integration which has a callback url providing input in query params and expecting a raw xml response.

Current situation

Scenario 1: Response returned is xml but content type is json

Scenario 1: If i set the header as xml then xml response comes in data field .

Expected

Content type as xml in header and response contains only xml

Hi @Umang01-hash — I’d love to help with this issue and contribute to implementing the XML content type handling.
Could you please share your thoughts or approach so I can align my work accordingly?

Hey @nitin-999-code! Thanks for picking this up!

The Issue: Currently, GoFr doesn't support raw XML responses. Any response gets JSON-encoded, even if you manually set Content-Type: application/xml.

See here:

gofr/pkg/gofr/http/responder.go

Line 83 in a581441

_ = json.NewEncoder(r.w).Encode(resp)

Approach: Add need to add a new XML response type similar to how File and Template work in the codebase — they write raw content and return early, bypassing JSON encoding.

Please let me know if you have any further questions regarding the above approach.

Thanks @Umang01-hash
Got it — I’ll review how File and Template handle raw responses and implement a similar XML response type that bypasses JSON encoding.
I’ll start working on this and share a draft PR once the initial implementation is ready.
