How do I retrieve a URL in Java?

WordPress Plugin Development: How do I retrieve the destination url of a redirected page with wp_remote_head()?

• The following function returns the url of a redirected page. function get_destination_url_curl( $url ) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url ); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $a = curl_exec($ch); curl_close($ch); if (preg_match('#Location: (.*)#', $a, $r)) return trim($r[1]); } I'm wondering if the WordPress http://codex.wordpress.org/HTTP_API can handle it. I tried the following code but the returned value of array[headers][location] is always empty. $args = array( 'redirection' => 0, ); $array_response = wp_remote_head( $url, $args ); echo '<pre>' . print_r( $array_response, true ) . '</pre>'

• Answer:

  wp_remote_head() should return a 'location' index in the resulting array... $result = wp_remote_head( $your_url, $your_args ); echo $result['headers']['location'];
