Data synchronization using RPC services developed by ThinkPHP6 and Swoole

Use ThinkPHP6 and the RPC service developed by Swoole to achieve data synchronization

With the development of the Internet, both large enterprises and individual developers are faced with the problem of data synchronization. need. Data synchronization refers to keeping data consistent between multiple systems to ensure data accuracy and completeness. In traditional data synchronization methods, database replication, ETL tools, etc. are often used to achieve it. However, these methods are often inefficient and have various problems when faced with scenarios such as large data volumes and high concurrency.

In recent years, RPC (Remote Procedure Call) remote procedure call technology has gradually become popular. RPC is a method of network or inter-process communication that enables calls and communications between different systems. Using RPC technology, we can easily achieve data synchronization between different systems.

In this article, we will introduce how to use ThinkPHP6 and Swoole framework to develop an RPC-based data synchronization service. ThinkPHP6 is a fast and flexible PHP development framework, and Swoole is a high-performance network communication engine based on PHP extensions.

The first step is to install ThinkPHP6 and Swoole framework. These two frameworks can be simply installed through the Composer command:

composer require topthink/think swoole

After the installation is completed, we can create a new ThinkPHP6 project:

think new rpc-sync

Next, we need to introduce Swoole into the project support. In the composer.json file in the project root directory, add the following content:

"swoole/ide-helper": "*"

Then execute the composer update command to install Swoole's IDE Helper.

Next, we need to create an RPC server. In the app/rpc directory of the project, create a Server directory and create the RpcServer.php file in this directory. The sample code is as follows:

<?php

namespace apppcServer;

use SwooleServer;
use SwooleProcess;
use thinkswooleRpcServer;
use thinkswoolepcPack;

class RpcServer
{
    protected $server;

    public function __construct()
    {
        $this->server = new Server('0.0.0.0', 9501, SWOOLE_PROCESS, SWOOLE_SOCK_TCP);

        $this->server->set(['worker_num' => 4]);

        $this->server->on('start', [$this, 'onStart']);
        $this->server->on('receive', [$this, 'onReceive']);

        // 注册RPC服务
        RpcServer::getInstance()
            ->setPackFormat([Pack::class, 'pack'], [Pack::class, 'unpack'])
            ->registerServer($this->server);

        // 注册自定义RPC方法
        RpcServer::getInstance()->registerService('syncData', [new SyncDataService(), 'syncData']);
    }

    public function onStart(Server $server)
    {
        Process::daemon();
    }

    public function onReceive(Server $server, $fd, $from_id, $data)
    {
        RpcServer::getInstance()->onReceive($server, $fd, $from_id, $data);
    }

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

In the above code, we created an RpcServer class and constructed it A Swoole Server object is instantiated in the function, and corresponding callback functions are registered in each event of the object.

Among them, the registerServer method is used to register Swoole Server into the RPC service. The registerService method is used to register a custom RPC service method. Here we register a method named syncData, which is specifically implemented in SyncDataService.php.

Next, we need to create an RPC client. In the app/rpc directory of the project, create a Client directory and create the RpcClient.php file in this directory. The sample code is as follows:

<?php

namespace apppcClient;

use thinkswoolepcClient;

class RpcClient
{
    protected $client;

    public function __construct()
    {
        $this->client = Client::getInstance();
    }

    public function getClient()
    {
        return $this->client;
    }

    public function syncData($data)
    {
        return $this->client->call('syncData', $data);
    }
}

In the above code, we created an RpcClient class and placed it in An RPC client object is instantiated in the constructor. In the syncData method, we call the remote syncData method.

Finally, we can instantiate the RpcServer and RpcClient classes in the project's entry file index.php, and use the RpcClient class to make data synchronization calls. The example is as follows:

<?php

use apppcServerRpcServer;
use apppcClientRpcClient;

require __DIR__ . '/../vendor/autoload.php';

$server = new RpcServer();
$server->start();

$client = new RpcClient();
$result = $client->syncData($data);

Through the above steps , we have implemented an RPC service based on ThinkPHP6 and Swoole, which can easily achieve data synchronization requirements.

Summary:
This article introduces how to use ThinkPHP6 and Swoole framework to develop an RPC-based data synchronization service. Through RPC technology, we can achieve data synchronization between different systems. In the specific implementation, we use the server and client components provided by Swoole to encapsulate the function of RPC calls, and use the framework support provided by ThinkPHP6 to simplify the development process.

In actual projects, we can expand and customize the functions of RPC services according to specific business needs. At the same time, you can also use the high-performance features of the Swoole framework to optimize the performance and concurrency of the system. I hope this article will be helpful to your data synchronization development work.
