How to return a NamedFile in a HttpResponse using Actix-web

Question

I try to return a NamedFile in a HttpRespose with this function

fn response(x: NamedFile)->HttpResponse{
        HttpResponse::Ok()
        .content_type(ContentType::html())
        .insert_header(("X-Hdr", "sample"))
        .body(x)
}

The function get called in my index file and returns the HttpRequest
is this even possible???

Answer 1

i solved it by introducing a new function that converts the content of the file into a single string

fn open(x: PathBuf) -> String{
    return fs::read_to_string(x)
        .expect("Something went wrong");
}

and used instead of NamedFile a String the function looks like this:

fn response(x: String, y:Response)->HttpResponse{

    match y{
        Response::OK => {
        HttpResponse::Ok()
        .content_type(ContentType::html())
        .insert_header(("X-Hdr", "sample"))
        .body(x)
        }
        Response::NOTOK => {
            HttpResponse::NotFound()
        .content_type(ContentType::html())
        .insert_header(("X-Hdr", "sample"))
        .body(x)
        }   
    }   
}
