MediaWiki:Apihelp-upload-extended-description

Several methods are available:

  • Upload file contents directly, using the $1file parameter.
  • Upload the file in pieces, using the $1filesize, $1chunk, and $1offset parameters.
  • Have the MediaWiki server fetch a file from a URL, using the $1url parameter.
  • Complete an earlier upload that failed due to warnings, using the $1filekey parameter.

Note that the HTTP POST must be done as a file upload (i.e. using multipart/form-data) when sending the $1file.
