This document is obsolete.

For the current specification, see: https://github.com/validator/validator/wiki/Service-»-Input-»-file-upload


To use Validator.nu as a Web service by form-based file upload:

  • the request uses the POST method with an multipart/form-data entity body
  • the document to check is included as the value of a file upload field called file
  • the file field must be the last field in the submission

Since the Content-Type supplied by browsers for the uploaded file is unreliable, the client-supplied Content-Type is overridden with a synthetic Content-Type if the filename is supplied and it has a well-known extension. The well-known extensions are html, htm, xhtml, xht, atom, rng, xsl, xml and dbk.

The parameter field values must decode as UTF-8.
