PHP realizes the API interface docking of Jingdong Industrial Platform and easily realizes the logistics tracking function!

1. Background introduction
Jingdong Industrial Platform is a platform under Jingdong Group that focuses on B2B e-commerce and provides one-stop purchasing solutions. During the transaction process, logistics tracking is a very important part, allowing buyers to understand the transportation status of the goods in real time. This article will introduce how to use PHP language to connect to the API interface of JD Industrial Platform to realize the logistics tracking function.

2. API preparation
Before starting, we need to prepare the following information:

1. The API documentation of Jingdong Industrial Platform can be obtained by applying for API development permission;
2. Developer account, key and API access address.

3. Code Example
In PHP, we can use the cURL library to make API requests. The following is a basic sample code:

<?php
// 京东工业平台API请求地址
$url = "https://api.jd.com/routerjson";
// 开发者账号和密钥
$appKey = "your_app_key";
$appSecret = "your_app_secret";
// 构造API请求参数
$param = array(
    "method" => "jd.logistics.trace.search",
    "app_key" => $appKey,
    "timestamp" => date("Y-m-d H:i:s"),
    "format" => "json",
    "v" => "2.0",
    "sign_method" => "md5",
    "param_json" => json_encode(array(
        "waybillCode" => "your_waybill_code"
    ))
);
// 生成API签名
$signStr = "";
ksort($param);
foreach ($param as $key => $value) {
    $signStr .= $key . $value;
}
$signStr .= $appSecret;
$param["sign"] = strtoupper(md5($signStr));
// 发起API请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($param));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
// 处理API响应结果
$result = json_decode($result, true);
if ($result["code"] == "0") {
    // 请求成功
    $traces = $result["result"]["traces"];
    foreach ($traces as $trace) {
        echo $trace["time"] . " " . $trace["remark"] . "<br/>";
    }
} else {
    // 请求失败
    echo "Error: " . $result["msg"];
}
?>

The above code implements a logistics tracking query request to the JD Industrial Platform and outputs the results to the page. Please replace the developer account, key and tracking number in the code according to the actual situation.

4. Summary
Through PHP to realize the API interface docking of Jingdong Industrial Platform, we can easily implement the logistics tracking function and provide users with a better shopping experience. Of course, the above code is just a simple example. In actual development, more complex API request and result processing logic may be required, which should be developed according to the API documentation of JD Industrial Platform. I hope this article can help developers in need.
