Implementing a high-performance online medical platform using Workerman

Use Workerman to implement a high-performance online medical platform

With the development of technology, the application of the Internet in the medical field is becoming more and more widespread. The online medical platform provides a convenient communication channel for patients and doctors, solving the problem of difficult and expensive medical treatment for patients. In order to ensure the high performance and stability of the platform, we can use PHP's high-performance network framework Workerman to implement it.

Workerman is a multi-process, multi-thread asynchronous network library based on PHP, which can achieve high concurrent network communication. Next we will use the Workerman framework to build an online medical platform.

1. Preparation
   First, we need to install and configure Workerman. Open the terminal and use the following command to install Workerman:

   composer require workerman/workerman

   Copy after login

Then, create a server file server.php and introduce Workerman’s automatic loading file and application logic file:

require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/app/clinic.php';

2. Write application logic
   Next, we need to write application logic. Create a clinic.php file in the app directory, which will handle the specific business logic of the medical platform.

First, we need to define a Clinic class to handle user requests:

use WorkermanConnectionTcpConnection;

class Clinic
{
    public function onConnect(TcpConnection $connection)
    {
        // 用户连接成功时触发
    }

    public function onMessage(TcpConnection $connection, $data)
    {
        // 处理用户消息
        $result = $this->processData($data);
        $connection->send($result);
    }

    public function onClose(TcpConnection $connection)
    {
        // 用户断开连接时触发
    }

    private function processData($data)
    {
        // 处理用户数据并返回结果
    }
}

In the onConnect method, we can handle the logic when the user connection is successful. In the onMessage method, we can process the message sent by the user and return the corresponding result. In the onClose method, we can handle the logic when the user disconnects.

3. Start the server
   Back to the server.php file, we need to create a Worker object and specify the address and port the server listens on:

   use WorkermanWorker;
   
   $worker = new Worker('tcp://0.0.0.0:2022');

   Copy after login

Then, we need to set some properties for the Worker object:

$worker->count = 4; // 设置worker进程数
$worker->name = 'clinic'; // 设置进程名称

Next, we can bind the logical processing class to the Worker object and specify the corresponding callback function:

$clinic = new Clinic();
$worker->onConnect = [$clinic, 'onConnect'];
$worker->onMessage = [$clinic, 'onMessage'];
$worker->onClose = [$clinic, 'onClose'];

Finally , we can start the Worker object and run the server:

Worker::runAll();

4. Client request
   In the client code, we can use PHP's socket function to connect to the server and send the request:

   $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
   socket_connect($socket, '127.0.0.1', 2022);
   
   $send_data = 'Hello, server!';
   socket_write($socket, $send_data, strlen($send_data));
   
   $recv_data = socket_read($socket, 1024);
   echo $recv_data;
   
   socket_close($socket);

   Copy after login

Run the above code to connect to the server and send a request. The server will process the request according to the business logic and return the corresponding results.

Using the Workerman framework to implement a high-performance online medical platform can greatly improve the concurrent processing capabilities and stability of the platform. Through the above sample code, we can clearly understand how to use the Workerman framework to build an online medical platform. Of course, in actual projects, we still need to consider more details and security, but the Workerman framework provides a good foundation for us to develop a high-performance medical platform.
