Learn PHP to connect to JD Industrial Platform API interface from scratch, and master user level query skills!

1. Background introduction
With the rapid development of the e-commerce industry, JD Industrial Platform has become an important channel for many companies to conduct B2B transactions. In order to better connect with the JD Industrial Platform, we need to learn how to use PHP to write code to access the API interface of the JD Industrial Platform. This article will take user level query as an example to introduce how to learn from scratch and master this technique.

2. Preparation work
Before we start, we need to prepare the following work:

1. Apply for a JD developer account, create an application, and obtain AppKey and AppSecret;
2. Make sure that the PHP environment has been installed locally and related extensions have been configured.

3. Write code
Next, we start writing code. First, create a PHP file named jd-api.php. In the file, we need to introduce the PHP SDK of Jingdong API, the code is as follows:

<?php
require_once 'src/JdSdk.php';

Next, we need to create a function getUserLevel to implement the user level query function. The code is as follows:

function getUserLevel($userToken) {
  // 创建JdSdk实例
  $appKey = 'your_app_key';  // 替换为你的AppKey
  $appSecret = 'your_app_secret';  // 替换为你的AppSecret
  
  $jdSdk = new JdSdk($appKey, $appSecret);
  
  // 设置用户令牌
  $jdSdk->setUserToken($userToken);
  
  // 构造请求参数
  $apiMethod = 'jd.user.level.get';  // 用户等级查询API
  $apiParams = array();
  
  // 调用京东API接口
  $result = $jdSdk->api($apiMethod, $apiParams);
  
  // 处理返回结果
  if ($result['code'] == 0) {
    // 查询成功，返回用户等级信息
    return $result['result'];
  } else {
    // 查询失败，返回错误信息
    throw new Exception('用户等级查询失败：' . $result['msg']);
  }
}

In the above code, the getUserLevel function accepts a parameter $userToken, which represents the user token. In the function, we first create a JdSdk instance and set the AppKey and AppSecret, and then use the setUserToken method to set the user token. Next, we constructed the request parameter $apiMethod as jd.user.level.get, which represents the user level query API. Then, call the $jdSdk->api($apiMethod, $apiParams) method to send the request and get the return result. Finally, determine whether the query is successful based on the code of the returned result. If successful, user level information will be returned. If failed, an exception will be thrown.

Next, we can call the getUserLevel function in the file to query the user level. The code is as follows:

$userToken = 'your_user_token';  // 替换为你的用户令牌

try {
  $userLevel = getUserLevel($userToken);
  echo '用户等级：' . $userLevel['userLevelName'];
} catch (Exception $e) {
  echo '查询失败：' . $e->getMessage();
}

In the above code, we replace the user token with your actual user token, and then call the getUserLevel function to query the user level. If the query is successful, the user level name is output; if the query fails, failure information is output.

4. Summary
Through the study of this article, we have learned how to learn PHP from scratch to connect to the JD Industrial Platform API interface, and mastered the user level query skills. In actual projects, we can expand more functions as needed and connect more closely with the JD Industrial Platform. I hope this article can help you achieve greater success in the e-commerce field!
