Amazon API 从产品中获取所有图像

Question

我有一个简单的问题，因为找不到任何答案。实际上，我可以使用 Amazon 的 API 从 ASIN 代码中获取有关产品的信息，但在这张图片的情况下，我可以得到一张不同格式的图片，大拇指、中拇指等，对吧？

在我的情况下，我想知道是否可以从产品中获取所有图像，不仅显示 1 张不同格式的图片，如果我可以使用抓取来获取所有图像，但在这种情况下，我想使用 API，因为它是更干净，并且使用抓取来自 CURL 的许多查询没有问题

其实我用这个：

$gallery=htmlentities((string) $item->ImageSets->ImageSet->LargeImage->URL);

项目结构：

$item = $xml->Items->Item;
$title = htmlentities((string) $item->ItemAttributes->Title);
$url = htmlentities((string) $item->DetailPageURL);
$image = htmlentities((string) $item->MediumImage->URL);
$price = htmlentities((string) $item->OfferSummary->LowestNewPrice->Amount);
$amount=htmlentities((string) $item->OfferSummary->LowestNewPrice->Amount);
$item->OfferSummary->LowestUsedPrice->Amount);
$code = htmlentities((string) $item->OfferSummary->LowestNewPrice->CurrencyCode);
$qty = htmlentities((string) $item->OfferSummary->TotalNew);
$gallery=htmlentities((string) $item->ImageSets->ImageSet->LargeImage->URL);

函数API代码：

function getAmazonPrice($region, $asin) 
{
global $precioamz;
global $amountamz;
global $imageamz;
global $galeriaamz;

$xml = aws_signed_request($region, array(
"Operation" => "ItemLookup",
"ItemId" => $asin,
"IncludeReviewsSummary" => False,
"ResponseGroup" => "Medium,OfferSummary",
));

$item = $xml->Items->Item;
$title = htmlentities((string) $item->ItemAttributes->Title);
$url = htmlentities((string) $item->DetailPageURL);
$image = htmlentities((string) $item->MediumImage->URL);
$price = htmlentities((string) $item->OfferSummary->LowestNewPrice->Amount);
$amount=htmlentities((string) $item->OfferSummary->LowestNewPrice->Amount);
 $item->OfferSummary->LowestUsedPrice->Amount);
$code = htmlentities((string) $item->OfferSummary->LowestNewPrice->CurrencyCode);
$qty = htmlentities((string) $item->OfferSummary->TotalNew);
$gallery=htmlentities((string) $item->ImageSets->ImageSet->LargeImage->URL);

/// $gallery=Images,ItemAttributes,Variations,VariationImages


if ($qty !== "0") 
{
$response = array(
"code" => $code,
"price" => number_format((float) ($price / 100), 2, '.', ''),
"image" => $image,
"url" => $url,
"title" => $title,
"amount" => $amount,
"galeria" => $gallery
);
}

$precioamz=$response['price'];
$amountamz=$response['amount'];
$imageamz=$response['image'];
$galeriaamz=$response['galeria'];

//return $response;
}

function getPage($url) 
{
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$html = curl_exec($curl);
curl_close($curl);
return $html;
}

但只能获得 1 张图片，我想获得该产品的所有图片，谢谢您的帮助，问候

Answer 1

获取您必须使用的所有图像，或添加

Images,ItemAttributes,Variations,VariationImages 当您调用 aws_signed_request() 时作为请求键 ResponseGroup 的值

我当然希望得到与您现在得到的不同的响应，因此您的响应解析代码可能需要修改。

检查响应并相应地编辑您的代码。

Answer 2

如果我没有误解您的要求，我假设您的 Amazon API XML 响应类似于我从 Amazon API 文档页面 https://docs.aws.amazon.com/AWSECommerceService/latest/DG/EX_RetrievingImages.html 获取的内容。所以你可以尝试这种方式来获取所有的图片网址。
