我试图找出在这里使用的方法。
我试图编写一些php来查询servlet并获取重定向URL /响应。
例如 - 转到此URL / servlet请求http://www.argos.ie/webapp/wcs/stores/servlet/CheckPriceAndStockCmd?partNum=5240793&storeSelection=4101将立即重定向到以下URL / servlet响应：http://www.argos.ie/webapp/wcs/stores/servlet/CheckPriceAndStockResultView?query-result=13&pickupStoreNumber2=826&pickupStore=Arklow&storeStockStatus=0&availableQuantityInStore2=1&storeStockStatus2=1&outOfStockEmail=&pickupStore2=Wexford&failureView=CheckPriceAndStockResultView&partNum=5240793&isExtraStoreRequest=0&promisedAvailTime2=2011-09-19&pickupStoreType=3&availableQuantityInStore=0&storeSelection=4101&pickupStoreNumber=4101&stockChecked=true&pickupStoreType2=3&promisedAvailTime=&estAvailTime=&catentryid=95934&estAvailTime2=&ddkey=http:CheckPriceAndStockCmd
我想基本上得到响应和其中的一些参数（我可以做后者）。
尝试过使用各种cURL方法输出标题和/或获取最终的重定向网址，但它们要么没用，要么非常慢：
$url = "http://www.argos.ie/webapp/wcs/stores/servlet/CheckPriceAndStockCmd?partNum=" . $catNum . "&storeSelection=" . $storeNum;
$ch = curl_init();
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt ($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
$content = curl_exec ($ch);
curl_close ($ch);
有人有任何建议吗？
