file_get_contents在端口8282上不起作用

我得到了以下基本脚本，他们提出了一个基本的POST请求（我只想让它工作，然后我会添加更多的东西）：

#   Variables
$URL = 'http://******:8282/api/incoming_shipment/';
$postdata = http_build_query(
    array(
        'contract_id'       => 'Showcare-R124276',
        'shipment_from'     => 'Montréal',
        'shipment_to'       => 'Chicago',
        'shipping_time'     => '2012-08-16 14:51:01',
        'tracking_cie'      => 'Poste Canada',
        'tracking_type'     => 'Standard',
        'tracking_number'   => 'EP645 9834 123 9773'
    )
);
$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);
$context = stream_context_create($opts);
$result = file_get_contents($URL, FALSE, $context);
print_r($result);

结果给我：

Warning: file_get_contents(http://******:8282/api/incoming_shipment/) [function.file-get-contents]: failed to open stream: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in D:'Inetpub'hightechhandling'api'api_push_contract.php on line 31
Fatal error: Maximum execution time of 30 seconds exceeded in D:'Inetpub'hightechhandling'api'api_push_contract.php on line 31

但当我用浏览器浏览网页时，它能完美地工作。我试过cURL和fsocketopen，但也没用。请帮忙吗？谢谢

EDIT我添加了set_time_limit (500);，现在第二个错误当然已经消失了。。。但第一个仍然存在。
