访问这个文件 url.php?goods=14535976817 通过商品id获取对应淘宝客链接,空白,好像没获取数据




require_once('lib/taobao/TopSdk.php');

$pid = pid;

$c = new TopClient;

$c->appkey = "appkey";

$c->secretKey = "secretKey";

if(isset($_GET['goods']) && is_numeric($_GET['goods']))

{

    $req = new TaobaokeItemsConvertRequest;

    $req->setFields("click_url,num_iid");

    $req->setPid($pid);

    $req->setNumIids($_GET['goods']);

    $resp = $c->execute($req);

    if(isset($resp->taobaoke_items->taobaoke_item->click_url))

    {

        $url = $resp->taobaoke_items->taobaoke_item->click_url;

    }

}

if(!empty($url))
