PHP implements logistics query function

With the continuous development of the e-commerce industry, more and more people choose to shop online. In this process, the logistics inquiry function has become a necessary service, because it allows consumers to know the transportation status of their goods and the estimated arrival time at any time. In this article, we will introduce how to use PHP to implement the logistics query function.

1. What is the logistics query function

The logistics query function refers to querying the logistics information of the user's goods, such as express delivery order number and route, through the official website of the logistics company or the third-party logistics query platform. , recipient, sender, receipt status, etc. For consumers, the logistics query function allows them to understand the logistics status of goods at any time and improve their shopping experience.

2. Steps to implement logistics query function

1. Obtain logistics information

First, we need to obtain the express order number entered by the user. This can be done through a simple form accomplish. Then, we need to call the logistics company's API interface to obtain the logistics information of the express delivery.

Taking SF Express as an example, we can call their API interface to obtain real-time logistics information of express delivery. The specific steps are as follows:

(1) Apply to open the API interface on the SF Express official website, and obtain the appkey and appsecret of the interface.

(2) Use the curl method to access the API interface and obtain the json format data of logistics information.

(3) Parse json data and display logistics information on the web page.

2. Display logistics information

Once we obtain the logistics information, we can display this information to the user. The specific display method can be defined by ourselves, for example, it can be displayed in a table or displayed in a chart. The key is to allow users to intuitively understand the logistics status and estimated arrival time of the goods.

3. Optimize query speed

For large e-commerce platforms, thousands of users may query logistics information at the same time, which requires us to optimize query speed to avoid slow response. Condition.

To achieve this goal, we can use caching technology. The specific method is to save the logistics information queried by the user in the cache server. The next time the user queries the same express delivery number again, the logistics information can be obtained directly from the cache server without going through the logistics company's API interface. Inquire.

3. Code example to implement the logistics query function

The following is a code example for a simple logistics query function:

<?php
$app_key = '1234567890'; //请将此处app_key修改为您申请的实际值
$app_secret = 'abcdefghijk'; //请将此处app_secret修改为您申请的实际值
$tracking_number = $_POST['tracking_number']; //获取用户输入的快递单号

//使用curl方法访问顺丰快递API接口
$url = "http://api.sf-express.com/sf-service-shipment-wsdl/SunYouService?wsdl";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'app_key' => $app_key,
    'app_secret' => $app_secret,
    'tracking_number' => $tracking_number,
));
$result = curl_exec($ch);
curl_close($ch);

//解析json格式数据
$data = json_decode($result, TRUE);

//展示物流信息
echo "<table>";
echo "<tr><td>快递单号：</td><td>".$data['tracking_number']."</td></tr>";
echo "<tr><td>当前状态：</td><td>".$data['status']."</td></tr>";
echo "<tr><td>预计到达时间：</td><td>".$data['estimate_delivery_time']."</td></tr>";
echo "</table>";
?>

The above code example is a simple logistics query function The implementation idea and specific implementation process need to be adjusted according to the specific parameters and return values ​​of the API interface.

4. Summary

By using PHP to implement the logistics query function, we can provide users with a better shopping experience, thereby improving the operational efficiency and user satisfaction of the e-commerce platform. It is worth noting that in the process of using the API interface, we need to comply with relevant laws and regulations, and the query results are not allowed to be used for illegal purposes. At the same time, in order to protect user privacy, we also need to strengthen data security protection.
