Class methods#

.new(file_path : String | Path, status : HTTP::Status | Int32 = HTTP::Status::OK, headers : HTTP::Headers = HTTP::Headers.new, public : Bool = true, content_disposition : ART::BinaryFileResponse::ContentDisposition? = nil, auto_etag : Bool = false, auto_last_modified : Bool = true) #

Instantiates self wrapping the file at the provided file_path, optionally with the provided status, and headers.

By default the response is ART::Response#set_public and includes a last-modified header, but these can be controlled via the public and auto_last_modified arguments respectively.

The content_disposition argument can be used to set the content-disposition header on self if it should be downloadable.

The auto_etag argument can be used to automatically set ETag header based on a SHA256 hash of the file.
