We do not implement this method, because authentication is done by ilias3/webdav.php.

Returns
bool true on successful authentication / public function check_auth($type, $user, $pass) { $this->writelog('check_auth type='.$type.' user='.$user.' pass='.$pass);

if (! $user) { return false; } return true; } Encodes an URL. This function differs from the PHP urlencode() function in the following way:

  • Unicode characters are composed into Unicode Normal Form NFC This ensures that WebDAV clients running on Windows and Mac OS X treat resource names that contain diacritic marks in the same way.
  • Slash characters '/' are preserved This ensures that path components are properly recognized by WebDAV clients.
  • Space characters are encoded as '%20' instead of '+'. This ensures proper handling of spaces by WebDAV clients.

ilDAVServer::getFileURI (   $refId,

)

Returns an URI for getting a file object using WebDAV.

Browsers can use this URI to download a file from ILIAS.

Note: This could be the same URI that is returned by getObjectURI. But we use a different URI, because we want to use the regular ILIAS authentication method, if no session exists, and we want to be able to download a file from the repository, even if the name of the file object is not unique.

Parameters
refIdof the file object.
ressourceNametitle of the file object (if known), to reduce SQL queries
parentRefIdrefId of parent object (if known), to reduce SQL queries
Returns
Returns the URI or null if the URI can not be constructed.
