An dieser Stelle nur ein kleines Beispiel, wie man mit PHP von sourceforge.net API ähnlich die Download URL zu einer Datei-Version eines Spiegel-Servers ermittelt mit Hilfe meiner sourceforge.net SF.net Klasse, die die Snoopy-Klasse erweitert, welche einen Web-Browser simuliert.
Hier die Klasse:
< ?php
/**
- @see http://snoopy.sourceforge.net/
/
require_once (dirname(FILE) . DIRECTORY_SEPARATOR . ‘Snoopy.class.php’);
/** - small and easy API like sourceforge.net file access class
- @author Holger Schadeck holger@schadeck.eu
- @access public
/
class SFnet extends Snoopy {
var $sProjectsBaseUrl = ‘http://sourceforge.net/projects/‘;
var $sProjectBaseUrl = ‘http://sourceforge.net/project/‘;
var $sDownloadBaseUrl = ‘http://downloads.sourceforge.net/‘;
var $host = ‘sourceforge.net’;
var $agent = ‘Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4’;
var $aProjectsFilesData = array ();
/**- gets links and data
- @access private
- @param string $sUrl URL
- @return mixed array of links data or boolean false
*/
function _getLinks($sUrl) {
$expandlinks = $this->expandlinks;
$this->expandlinks = false;
if ($this->fetch($sUrl)) {
$aLinks = $this->_striplinks($this->results);
$aLinks = array_combine($aLinks, $this->_expandlinks($aLinks, $sUrl));
$aReturnLinks = array ();
foreach ($aLinks as $sLocal => $sRemote) {
if (preg_match(‘/<a .
$sRemote = html_entity_decode(utf8_decode($sRemote));
$sLocal = html_entity_decode(utf8_decode($sLocal));
$aReturnLinks[$sRemote] = array (
‘text’ => trim(html_entity_decode(utf8_decode($aFound[1]
))), ‘url_download’ => $sRemote, ‘data’ => parse_url($sRemote), ‘args’ => array ());
parse_str($aReturnLinks[$sRemote][‘data’][‘query’], $aReturnLinks[$sRemote][‘args’]);
}
}
$mReturn = $aReturnLinks;
} else {
$mReturn = (false);
}
$this->expandlinks = $expandlinks;
return $mReturn;
}

}
?>Hier das Beispiel:
< ?php
/**

/**

/**
*/
$sProject = ‘mingw’;
/**
*/
foreach ($SFprojects->getFilesOfProject($sProject) as $sFile => $aFileData) {
/**

- the use of SFnet::getDownloadUrlForProjectFile and SFnet::getTimeForProjectFile methods normally make no sense,
- if its project name is the same as the project name of the project files loop,
- because you can get the data from the file data array, here $aFileData[‘download_url’] and $aFileData[‘args'[‘modtime’]];
- @see SFnet::getFilesOfProject
*/
echo $sFile . ‘ => ‘ . $SFprojects->getDownloadUrlForProjectFile($sProject, $sFile) . ‘ (Modifiziert: ‘ . $SFprojects->getTimeForProjectFile($sProject, $sFile) . ‘)
‘;
}
?>
Wie man vielleich sieht, kann man sogar den Timestamp des Änderungsdatums ermitteln.

Funzt nicht bei mir 🙁

Schade sowas such ich nämlich.
