sourceforge.net: API ähnlich aktuelle Datei-Download-URLs ermitteln

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 .

  ?href=[‘"]’ . preg_quote($sLocal, ‘/’) . ‘[‘"].?>(.?)< /a>/i’, $this->results, $aFound)) {
  $sRemote = html_entity_decode(utf8_decode($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;
  }
  /**

  function getFilesOfProject($sProject) {
  $sProjectUrl = $this->sProjectsBaseUrl . $sProject . ‘/’;
  $sDownloadUrl = $this->sDownloadBaseUrl . $sProject;
  if (!array_key_exists($sProject, $this->aProjectsFilesData) && $aLinks = $this->_getLinks($sProjectUrl)) {
  $aReturnLinks = array ();
  foreach (preg_grep(‘/^’ . preg_quote($this->sProjectBaseUrl . ‘showfiles.php’, ‘/’) . ‘.group_id=([0-9]+?).?#downloads$/’, array_keys($aLinks)) as $iKey => $sUrl) {
  if ($aLinks = $this->_getLinks($sUrl)) {
  $this->aProjectsFilesData[$sProject] = array ();
  foreach (preg_grep(‘/^’ . preg_quote($sDownloadUrl, ‘/’) . ‘/’, array_keys($aLinks)) as $iKey => $sFileUrl) {

  function getDownloadUrlForProjectFile($sProject, $sFile) {

  function getTimeForProjectFile($sProject, $sFile) {

  }
  }
  ?>

  Hier das Beispiel:
  
< ?php
/**

*/
/**

*/
require_once (‘lib/sourceforge.net.php’);
$SFprojects = new SFnet();
/**

declare the target project
*/
$sProject = ‘mingw’;
/**

loop over project file
*/
foreach ($SFprojects->getFilesOfProject($sProject) as $sFile => $aFileData) {
/**

• show each file with download URL and modification timestamp
• 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.
