PHP Amazon API development: How to deal with product classification and tags

Introduction:
Amazon is one of the largest e-commerce platforms in the world. Its API (Application Programming Interface) allows developers to program through ways to interact with its platform. Handling product classification and tags is a very important step when developing an application based on Amazon API. This article will introduce how to use PHP language to process Amazon product classification and tags, and attach relevant code examples.

1. Obtain product classification

1. First, we need to use the Product Advertising API provided by Amazon to obtain product classification information. Before using the API, you need to register a developer account on the Amazon Developer Platform and create an API key.
2. In PHP, we can use the curl library to send HTTP requests to interact with the Amazon API. The following is a simple code example that shows how to use the Amazon API to obtain product classification information:

<?php
$access_key = "YOUR_ACCESS_KEY";
$secret_key = "YOUR_SECRET_KEY";
$associate_tag = "YOUR_ASSOCIATE_TAG";

$base_url = "http://webservices.amazon.com/onca/xml";

$params = array(
    "Service" => "AWSECommerceService",
    "Operation" => "BrowseNodeLookup",
    "BrowseNodeId" => "0", // 根菜单分类
    "ResponseGroup" => "BrowseNodes",
    "AssociateTag" => $associate_tag,
    "AWSAccessKeyId" => $access_key,
);

$canonical_query_string = http_build_query($params);

$signature = base64_encode(hash_hmac("sha256", "GET
webservices.amazon.com
/onca/xml
" . $canonical_query_string, $secret_key, true));

$request_url = $base_url . "?" . $canonical_query_string . "&Signature=" . urlencode($signature);

// 发送HTTP请求并获取响应
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析响应XML并提取商品分类信息
$xml = simplexml_load_string($response);
$browse_nodes = $xml->xpath('//BrowseNode');

foreach ($browse_nodes as $browse_node) {
    $node_id = (string)$browse_node->BrowseNodeId;
    $name = (string)$browse_node->Name;
    // 打印分类信息
    echo "分类ID: " . $node_id . ", 分类名称: " . $name . "
";
}
?>

In the above code, we obtain product classification information by sending a BrowseNodeLookup request to the API. YOUR_ACCESS_KEY, YOUR_SECRET_KEY, and YOUR_ASSOCIATE_TAG need to be replaced with your own Amazon API key and associated tag.

2. Obtain product tags

1. Similarly, we can also use Amazon API to obtain product tag information. The following is a sample code that shows how to use PHP to obtain product tags:

<?php
$access_key = "YOUR_ACCESS_KEY";
$secret_key = "YOUR_SECRET_KEY";
$associate_tag = "YOUR_ASSOCIATE_TAG";

$base_url = "http://webservices.amazon.com/onca/xml";

$params = array(
    "Service" => "AWSECommerceService",
    "Operation" => "ItemLookup",
    "ItemId" => "B00EOE0WKQ", // 商品ASIN码
    "ResponseGroup" => "ItemAttributes",
    "AssociateTag" => $associate_tag,
    "AWSAccessKeyId" => $access_key,
);

$canonical_query_string = http_build_query($params);

$signature = base64_encode(hash_hmac("sha256", "GET
webservices.amazon.com
/onca/xml
" . $canonical_query_string, $secret_key, true));

$request_url = $base_url . "?" . $canonical_query_string . "&Signature=" . urlencode($signature);

// 发送HTTP请求并获取响应
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析响应XML并提取商品标签信息
$xml = simplexml_load_string($response);
$tags = $xml->xpath('//ItemAttributes/Feature');

foreach ($tags as $tag) {
    // 打印商品标签
    echo "标签: " . (string)$tag . "
";
}
?>

In the above code, we obtain the product tag by sending an ItemLookup request to the API and passing in the ASIN code of the product. YOUR_ACCESS_KEY, YOUR_SECRET_KEY, and YOUR_ASSOCIATE_TAG need to be replaced with your own Amazon API key and associated tag.

Conclusion:
Handling product classification and labeling is an important task when developing applications based on Amazon API. By using PHP language, we can easily interact with Amazon API and get the required classification and tag information. The above provides code examples for processing product classification and labeling. I hope it can help you practice in Amazon API development.
