ContentDisposition

Online documentation | Hex.pm

ContentDisposition helps properly formatting Content-Disposition headers.

Inspired by Ruby's content_disposition gem, this package formats a given disposition and optional filename to an acceptable value for the Content-Disposition header. It takes care of encoding, escaping and adds an ASCII fallback.

Examples

# Without filename
iex> ContentDisposition.format(disposition: :inline)
"inline"

# With a filename, and disposition as a string
iex> ContentDisposition.format(disposition: "inline", filename: "kitten.jpg")
"inline; filename=\"kitten.jpg\"; filename*=UTF-8''kitten.jpg"

# With a UTF-8 filename as attachment
iex> ContentDisposition.format(disposition: :attachment, filename: "kïttéñ.jpg")
"attachment; filename=\"k%3Ftt%3F%3F.jpg\"; filename*=UTF-8''k%C3%AFtt%C3%A9%C3%B1.jpg"
