How to use PHP to connect to Alibaba Cloud Query API to implement the order information query function

With the development of e-commerce, more and more enterprises choose to use Alibaba Cloud as their cloud computing service provider. For enterprises, order information is a very important part, so being able to query Alibaba Cloud order information through code will greatly facilitate enterprise management.

This article will introduce how to use PHP to connect to Alibaba Cloud's query API to implement the order information query function. Specifically, we will query order information through interface calls and demonstrate how to obtain the returned results in a code example.

Step 1: Preparation
Before we start, we need to do some preparations.
The first step is to register an Alibaba Cloud account and activate the corresponding services. Make sure you have opened access to Alibaba Cloud API Gateway and corresponding services.
The second step is to obtain Alibaba Cloud's Access Key ID and Access Key Secret. This information will be used for identity verification when connecting to the Alibaba Cloud API.
The third step is to install the PHP curl extension. The curl extension is a functional extension in PHP for sending HTTP requests.

Step 2: Write query code
First, we need to define some parameters required to call Alibaba Cloud API.

$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$orderId = 'your_order_id';

Next, we need to construct the header information and parameters of the request.

$headers = array(
    'Content-Type: application/json',
    'X-Ca-Version: 1',
    'X-Ca-Key: ' . $accessKeyId,
    'X-Ca-Signature: ' . $signature,
);

$query = array(
    'orderId' => $orderId,
);

$url = 'https://your_api_host/queryOrder';

Among them, $signature is the signature information calculated according to the interface calling rules.

Then, we use curl extension to send HTTP request and get the return result.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($query));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
curl_close($ch);

Finally, we can parse the returned results and display relevant information.

$response = json_decode($result);
if ($response->code === '200') {
    $orderInfo = $response->data;
    echo '订单状态：' . $orderInfo->status . '<br>';
    echo '订单金额：' . $orderInfo->amount . '<br>';
    echo '订单创建时间：' . $orderInfo->createTime . '<br>';
} else {
    echo '查询失败：' . $response->message;
}

Step 3: Use the query code
Now, we have completed writing the query code. Next, we'll use the code we just wrote to query order information.

$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$orderId = 'your_order_id';

$headers = array(
    'Content-Type: application/json',
    'X-Ca-Version: 1',
    'X-Ca-Key: ' . $accessKeyId,
    'X-Ca-Signature: ' . $signature,
);

$query = array(
    'orderId' => $orderId,
);

$url = 'https://your_api_host/queryOrder';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($query));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
curl_close($ch);

$response = json_decode($result);

if ($response->code === '200') {
    $orderInfo = $response->data;
    echo '订单状态：' . $orderInfo->status . '
';
    echo '订单金额：' . $orderInfo->amount . '
';
    echo '订单创建时间：' . $orderInfo->createTime . '
';
} else {
    echo '查询失败：' . $response->message;
}

It should be noted that you need to replace the corresponding parameters in the above code with your own Alibaba Cloud Access Key and order ID.

Summary
This article introduces how to use PHP to connect to the Alibaba Cloud Query API to implement the order information query function. First, we completed some preparatory work, including registering an Alibaba Cloud account, obtaining Access Key information, and installing the curl extension. Then, we wrote the query code and demonstrated how to use the query code to query order information through code examples. I hope this article will be helpful to you in using PHP to connect to Alibaba Cloud Query API.
