Sends the given binary data to the browser. This method is similar to
render plain: data
, but also allows you to specify whether the
browser should display the response as a file attachment (i.e. in a
download dialog) or as inline data. You may also set the content type, the
apparent file name, and other things.
Options:
-
:filename
- suggests a filename for the browser to use. -
:type
- specifies an HTTP content type. Defaults to 'application/octet-stream'. You can specify either a string or a symbol for a registered type register withMime::Type.register
, for example :json If omitted, type will be guessed from the file extension specified in:filename
. If no content type is registered for the extension, default type 'application/octet-stream' will be used. -
:disposition
- specifies whether the file will be shown inline or downloaded. Valid values are 'inline' and 'attachment' (default). -
:status
- specifies the status code to send with the response. Defaults to 200.
