Taobao Order Comment API Document Interpretation, PHP Practical Guide

Introduction:
In today's e-commerce era, online shopping has become a way of life for more and more people. In shopping websites, user evaluations are a very important reference indicator, which can help other users better understand the quality of products, services, etc. In order to facilitate developers to obtain user evaluation data and apply it to their own systems, Taobao provides an order review API. This article will interpret the documentation of the Taobao Order Comment API and provide guidelines for practical development using PHP.

1. Overview of Order Comment API
Taobao Order Comment API provides the function of obtaining evaluation data under a specific order. It can obtain the basic information of the order, such as evaluation level, evaluation content, evaluation time, etc. Using this API, developers can flexibly obtain evaluation data under specific orders for secondary development according to their own needs.

2. Interpretation of API technical documents
In the documentation of Taobao open platform, the order comment API is classified as a transaction API. Its complete document provides a detailed interface description, including interface name, request Address, request method, request parameters, response parameters, etc. Before using the API, you first need to understand the information provided by the documentation. For beginners, it is extremely important to understand the API request address, request method and request parameters.

1. Request address
   The request address of the API refers to the URL address that needs to send a request to the Taobao server. According to the description of the API document, we can know that the request address of the order comment API is: https://api.taobao.com/router/rest, which is the unified request address of the Taobao API.
2. Request method
   The API request method determines how developers operate when calling the API. According to the description in the API documentation, we can know that the request method of the order comment API is an HTTP POST request. In PHP, you can use the curl library or the file_get_contents function to send POST requests.
3. Request parameters
   The request parameters of API are data used to send specific requests to the server. According to the description of the API document, you can see that the order comment API requires the following necessary parameters: method, app_key, session, sign, etc. Among them, the method parameter represents the interface name, the app_key parameter represents the App Key of the application, the session parameter represents the access token, and the sign parameter is used to request a signature to ensure the legitimacy of the request.

3. Use PHP for practical development
After mastering the documentation of Taobao order comment API, the following will demonstrate how to use PHP for practical development through a simple example.

Suppose our goal is to obtain the evaluation data of an order and display it on our website. First, we need to log in using the Taobao Open Platform account and obtain the App Key and access token.

In the PHP code, we first need to prepare the request parameters:

$appKey = "your_app_key";
$session = "your_access_token";
$method = "taobao.traderates.get";
$order_id = "123456789"; // 待获取评论的订单ID

$params = array(
    'app_key' => $appKey,
    'session' => $session,
    'method' => $method,
    'order_id' => $order_id,
);

Then, we need to sign the request parameters to ensure the legitimacy of the request:

ksort($params);
$sign = '';
foreach ($params as $key => $value) {
    $sign .= $key . $value;
}
$sign .= 'your_app_secret';
$sign = strtoupper(md5($sign));
$params['sign'] = $sign;

Next , we use the curl library to send a POST request to obtain the evaluation data:

$url = "https://api.taobao.com/router/rest";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// 解析API返回的数据
$result = json_decode($response, true);
if ($result && isset($result['traderates_get_response'])) {
    $commentData = $result['traderates_get_response']['trade_rates'];
    foreach ($commentData as $comment) {
        $content = $comment['content'];
        $time = $comment['created'];
        echo "评价内容：".$content."，评价时间：".$time."<br>";
    }
}

Through the above code, we can successfully call the Taobao order comment API and display the evaluation data on the web page.

Conclusion:
This article interprets the documentation of the Taobao order review API, and demonstrates the use of the API through a practical example using PHP. I hope this article can help readers better understand the API documentation and master how to use the Taobao order comment API for development. In actual development, developers can flexibly use this API according to their own needs and combine it with their own business logic to provide users with better services.
