Develop a highly available logistics tracking system based on Swoole

Developing a highly available logistics tracking system based on Swoole

With the rapid development of e-commerce, the logistics industry is also growing. In order to meet users' needs for logistics tracking, many logistics companies have launched their own tracking systems. In order to provide better services and higher availability, the logistics tracking system needs to have high concurrent processing capabilities and real-time push functions. In this context, we can consider using Swoole for development to implement a highly available logistics tracking system.

Swoole is an asynchronous, high-performance network communication engine based on PHP, which can easily achieve high concurrency processing and real-time push functions. Below we will take the logistics tracking system as an example to introduce how to develop it based on Swoole.

First, we need to prepare a prototype of the logistics tracking system. Suppose we already have a database table orders, which records order numbers and logistics information. We can create a index.php file as the entry file of the system.

<?php

// 引入Swoole的autoload文件
require_once './vendor/autoload.php';

// 创建Swoole的HTTP服务器
$http = new SwooleHttpServer("127.0.0.1", 9501);

// 设置请求处理函数
$http->on('request', function ($request, $response) {

    // 路由处理
    $path = $request->server['path_info'];
    switch ($path) {
        case '/orders':
            // 查询订单接口
            $this->getOrders($request, $response);
            break;
        case '/track':
            // 查询物流接口
            $this->getTrack($request, $response);
            break;
        default:
            $response->status(404);
            $response->end();
            break;
    }
});

// 启动服务器
$http->start();

The above code creates a Swoole HTTP server and sets the request processing function. Among them, the interface type requested by the user is determined through routing, and then the corresponding processing function is called for processing.

Next, we can implement the getOrders() and getTrack() functions to handle the corresponding interface requests.

function getOrders($request, $response)
{
    // 处理查询订单的逻辑

    // 从数据库中查询订单信息
    $orders = $this->queryOrders();

    // 返回订单信息
    $response->header("Content-Type", "application/json");
    $response->end(json_encode($orders));
}

function getTrack($request, $response)
{
    // 处理查询物流的逻辑

    // 获取请求参数
    $orderId = $request->get['orderId'];

    // 查询物流信息
    $track = $this->queryTrack($orderId);

    // 返回物流信息
    $response->header("Content-Type", "application/json");
    $response->end(json_encode($track));
}

In the above code, the getOrders() and getTrack() functions handle the logic of querying orders and querying logistics respectively. We can implement these functions according to actual needs.

Finally, we need to start the Swoole server to run the logistics tracking system.

$ php index.php

Through this simple logistics tracking system example, we can see that it becomes easier to develop a highly available logistics tracking system using Swoole. Swoole provides asynchronous, high-performance network communication capabilities, through which we can easily implement high concurrency processing and real-time push functions. Of course, a real logistics tracking system requires more functions and technical support, and we can expand and optimize it according to actual needs.
