Piwik JS Tracking Code should use DNS name instead of IP

[anonymous-matomo-user]

Hi,

if you request the JS tracking Code via the API and the 'piwikUrl' Parameter isn't set, Piwik tries to recognize the correct URL. This is done in plugins/SitesManager/API.php function getJavascriptTag:

if (empty($piwikUrl)) {
    $piwikUrl = Url::getCurrentUrlWithoutFileName();
}

In times where we're trying to slowly migrate to IPv6 this is really bad! Piwik should use the DNS name, not the IP.

Request:

http://example.org/piwik/?module=API&method=SitesManager.getJavascriptTag&idSite=1&period=&date=&filter_limit=&token_auth=abcdefghij12354687&expanded=&format=PHP

Response:

s:880:"<!-- Piwik -->
<script type="text/javascript">
  var _paq = _paq || [];
  _paq.push(['trackPageView']);
  _paq.push(['enableLinkTracking']);
  (function() {
    var u=(("https:" == document.location.protocol) ? "https" : "http") + "://2a02:8070:8360:xxxx:xxxx:85b0:xxxx:xxxx/piwik/";
    _paq.push(['setTrackerUrl', u+'piwik.php']);
    _paq.push(['setSiteId', 1]);
    var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0]; g.type='text/javascript';
    g.defer=true; g.async=true; g.src=u+'piwik.js'; s.parentNode.insertBefore(g,s);
  })();

</script>

<!-- End Piwik Code -->
";

It would be great if someone with real understanding of Piwik and PHP could fix this.

Thanks in advance!

Check the trusted_hosts setting in your config.ini.php. The fallback to the server address happens if the value of the Host: header isn't in the trusted_hosts list.
