Help with Header-Based API Versioning

[MBoui]

Hi,

I'm implementing header-based API versioning using the x-api-version header.
My goals are:

• Routing: Redirect requests to the appropriate handler (handler-1 for version-1, handler-2 for version-2) based on the header value.
• Clean URL: Maintain the same endpoint /my-endpoint for all versions.
• Defaulting: Route requests without the header (or invalid versions) to the latest handler (handler-2).

I'd appreciate assistance in determining the best way to achieve this.

Thanks guys!

like this?

 Router::with_path("my-endpoin").push(
        Router::with_filter_fn(|req, _|{
            req.header::<String>("x-api-version").as_deref() == Some("version1")
        }).get(version1)
    ).push(
        // This is for header has version 2 and without header.
        Router::new().get(version2)
    )
