来自 cUrl 请求的格式响应

Question

我正在开发亚马逊 MWS，并尝试使用 GetMatchingProductForId 从 SKU 获取产品详细信息。我得到的回应是：

SimpleXMLElement Object
(
    [GetMatchingProductForIdResult] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [Id] => VYPL039_$P
                    [IdType] => SellerSKU
                    [status] => Success
                )

            [Products] => SimpleXMLElement Object
                (
                    [Product] => SimpleXMLElement Object
                        (
                            [Identifiers] => SimpleXMLElement Object
                                (
                                    [MarketplaceASIN] => SimpleXMLElement Object
                                        (
                                            [MarketplaceId] => A21TJRUUN4KGV
                                            [ASIN] => B00NA3ZMKM
                                        )

                                )

                            [AttributeSets] => SimpleXMLElement Object
                                (
                                )

                            [Relationships] => SimpleXMLElement Object
                                (
                                )

                            [SalesRankings] => SimpleXMLElement Object
                                (
                                )

                        )

                )

        )

    [ResponseMetadata] => SimpleXMLElement Object
        (
            [RequestId] => 9e893248-adaf-43a1-bcae-70f62b6888c7
        )

)

cURL 请求：

$url = "https://mws.amazonservices.in/Products/2011-10-01" . '?' . $url_string . "&Signature=" . $signature;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, 15);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        $response = curl_exec($ch); 

        //echo $url;exit;

$responseDoc = new DOMDocument();
        $responseDoc->loadXML($response);

        $response = simplexml_import_dom($responseDoc);

echo '<pre>';
        print_r($response);
        echo '</pre>';
        exit;

但是为什么响应少了，但是当我在浏览器中运行 url 时，它给了我完整的响应，如下所示：-

<GetMatchingProductForIdResponse xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">

编辑：-

我现在已将响应格式更改为 SimpleXMLElement::asXML ：

$url = "https://mws.amazonservices.in/Products/2011-10-01" . '?' . $url_string . "&Signature=" . $signature;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, 15);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        $response = curl_exec($ch);

$parsed_xml = simplexml_load_string($response); 
$response = $parsed_xml->asXML();

但是$response 什么也没返回。

Answer 1

我不知道这是否适合你，但它对我来说很好：

$response = str_replace("ns2:","",$response);
$responseDoc = new DOMDocument();
$responseDoc->loadXML($response);

$response = simplexml_import_dom($responseDoc);

echo '<pre>';
print_r($response);
echo '</pre>';
exit;

请检查上面的代码。
