You currently can’t subscribe to an authenticated feed (for example in Basecamp) in Google Reader.
If you want to do it nonetheless you can use this script of mine which will talk to the server that needs authentication, passing through all the headers (so that also cookies and “not modified” requests will come through): download authenticated-feed-passthru.php
<?php
// change this url
$url = "https://username:password@proj.basecamphq.com/projects/123/feed/recent_items_rss";
$ch = curl_init($url);
if (isset($_SERVER['REQUEST_METHOD']) && strtolower($_SERVER['REQUEST_METHOD']) == 'post') {
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
}
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$headers = array();
foreach ($_SERVER as $name => $value) {
if (substr($name, 0, 5) != 'HTTP_') continue;
if ($name == "HTTP_HOST") continue;
$headers[] = str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5))))) . ": " . $value;
}
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
list($header, $contents) = preg_split('/([\r\n][\r\n])\\1/', curl_exec($ch), 2);
curl_close($ch);
foreach (preg_split('/[\r\n]+/', $header) as $header) {
header($header);
}
echo $contents;
If you don’t mind giving away your credentials you can also use Free My Feed.
