PHP:使用cURL PUT发送XML数据

我想更新我的库存在西尔斯市场与API。

" 库存管理:这个API调用使用PUT方法来管理物品的库存级别。为了避免错误，库存更新应该只对已成功处理的项目进行。注意:库存不会自动减少，所以在收到和处理订单时更新库存是很重要的。"

PUT URL: https://seller.marketplace.sears.com/SellerPortal/api/inventory/fbm-lmp/v6?email={emailaddress}&password={password}

XSD: https://seller.marketplace.sears.com/SellerPortal/s/schema/rest/inventory/import/v6/store-inventory.xsd?view=markup

示例XML: https://seller.marketplace.sears.com/SellerPortal/s/schema/samples/rest/inventory/import/v6/store-inventory.xml?view=markup

API文档:
http://searsmarketplace.force.com/articles/FAQ/XML-How-do-I-update-inventory?retURL=%2Fapex%2FknowledgeProduct%3Fc%3DContent%26k%3D&弹出= false

我创建了以下脚本，但不能正常工作:

$xml = '<?xml version="1.0" encoding="UTF-8"?>
    <store-inventory
        xmlns="http://seller.marketplace.sears.com/catalog/v2"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://seller.marketplace.sears.com/SellerPortal/s/schema/rest/inventory/import/v2/store-inventory.xsd">
        <item item-id="10">
            <locations>
                <location location-id="21">
                    <quantity>20</quantity>
                    <pick-up-now-eligible>false</pick-up-now-eligible>
                </location>
            </locations>
        </item>
    </store-inventory>';
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_URL, "https://seller.marketplace.sears.com/SellerPortal/api/inventory/fbm-lmp/v6?email={email}&password={pass}"); 
curl_setopt($ch, CURLOPT_PORT, 443);
curl_setopt($ch, CURLOPT_PUT, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS,array($xml));
$http_result = curl_exec($ch);
if($http_result){
    echo $http_result;
}else{
    echo curl_error($ch);
}
curl_close($ch); 

curl_error:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
