Using Swoole to implement a high-performance online medical platform

Use Swoole to implement a high-performance online medical platform

With the continuous development of information technology, the Internet has been widely used in various industries, and the medical industry is no exception . The traditional offline medical model faces many problems, such as difficulty in seeing a doctor, long queues, and time limits for outpatient clinics. Through the Internet and mobile devices, medical services can be made more convenient and efficient, and the pain points of offline medical care can be solved. This article will introduce how to use Swoole to implement a high-performance online medical platform.

1. Introduction to Swoole

Swoole is a C extension of PHP that provides enhancements to the PHP language and support for the underlying network library, and can be used to build high-performance, asynchronous network applications. It supports coroutines, asynchronous tasks, TCP/UDP, WebSocket, etc., can handle massive concurrent connections, and provides high-performance network programming capabilities.

2. Medical platform service architecture design

The following is a simple schematic diagram of the medical platform service architecture design:

                [医生端]      [患者端]      
                --------      --------      
                 |              |          
        +-----------------------------+    
        |        医疗平台服务         |    
        +-----------------------------+    
                 |   |   |                
          +------------|------------+     
          |            |            |     
       +-------+    +-------+     +-------+
       | MySQL |    | Redis |     |其他服务|
       +-------+    +-------+     +-------+

The medical platform service mainly includes two parts: the doctor side and the patient side. , they conduct data interaction and business processing through medical platform services. The server needs to interact with the database (MySQL) and cache (Redis), and may also need other interfaces or microservices for auxiliary function support.

3. Doctor terminal implementation

The doctor terminal is a tool used by doctors to provide medical services and communicate with patients. The following is a simplified doctor-side sample code:

<?php

class DoctorServer
{
    private $server;

    public function __construct()
    {
        $this->server = new SwooleHttpServer('0.0.0.0', 9501);
        $this->server->on('request', [$this, 'handleRequest']);
    }

    public function handleRequest($request, $response)
    {
        // 处理医生端请求的逻辑
        // 包括登录验证、消息推送、发起咨询等功能
        
        $response->header('Content-Type', 'text/plain');
        $response->end('Hello, Doctor!');
    }

    public function start()
    {
        $this->server->start();
    }
}

$doctorServer = new DoctorServer();
$doctorServer->start();

The above code creates an HTTP server, listens to port 9501, and defines a handleRequest method to handle requests from the doctor. In practical applications, doctor-side functions can be developed according to specific needs.

4. Patient terminal implementation

The patient terminal is a tool used by patients to receive consultation from doctors and query medical information. The following is a simplified patient-side sample code:

<?php

class PatientClient
{
    private $client;

    public function __construct()
    {
        $this->client = new SwooleHttpClient('127.0.0.1', 9502);
    }

    public function request($data)
    {
        $this->client->post('/consult', $data, function($response) {
            // 处理患者咨询的响应数据
            var_dump($response);
            
            $this->client->close();
        });
    }

    public function connect()
    {
        $this->client->on('connect', function() {
            echo "Connected to server
";
        });

        $this->client->on('error', function($msg) {
            echo "Error: $msg
";
        });

        $this->client->on('close', function() {
            echo "Connection closed
";
        });

        $this->client->upgrade('/', function($response) {
            // 处理客户端升级的响应数据
        });
    }
}

$patientClient = new PatientClient();
$patientClient->connect();
$patientClient->request(['message' => 'Hello, Doctor!']);

The above code creates an HTTP client, connects to the 9502 port of the medical platform service, and defines a request method to send a consultation ask. In practical applications, patient-side functions can be developed according to specific needs.

5. Summary

This article introduces the basic ideas and sample code for using Swoole to implement a high-performance online medical platform. Swoole provides high-performance, asynchronous network programming capabilities, which can be applied in various Internet applications to achieve better user experience and efficiency improvement. In practical applications, it is also necessary to design and develop medical platform services based on specific business requirements and system architecture. I hope this article will be helpful to readers in implementing a high-performance online medical platform.
