Implement efficient data filtering using RPC services developed by ThinkPHP6 and Swoole

Title: RPC service implementation of efficient data filtering based on ThinkPHP6 and Swoole

Introduction:
In the current big data era, data processing and filtering are very important. For important tasks, especially when filtering large amounts of data, traditional single-threaded filtering is often inefficient. This article will introduce how to use ThinkPHP6 and Swoole to develop an efficient RPC service to achieve rapid filtering and processing of data, and provide specific code examples.

1. Preparation

1. Install Swoole extension
   Swoole is a PHP extension developed based on C language, which can realize the asynchronous, high concurrency and other features of PHP. Swoole can be installed through the following command:

   pecl install swoole

2. Install the ThinkPHP6 framework
   Use Composer to install the ThinkPHP6 framework:

   composer create-project topthink/think

3. Create project
   In the ThinkPHP6 framework Create a new project in .

2. Build RPC service

1. Create RPC service class
   Create the Rpc directory in the app/rpc directory of the project, and then create the RPC directory in the Rpc directory Create the FilterService.php file and copy the following code to FilterService.php:

   <?php
   namespace apppcRpc;
   
   use HyperfRpcServerAnnotationRpcService;
   
   /**
    * @RpcService(name="FilterService", protocol="jsonrpc")
    */
   class FilterService
   {
    public function filterData($data, $filter)
    {
        // 数据过滤逻辑
        // ...
        return $filteredData;
    }
   }

2. Configuring the RPC service
   Create a hyperf.php in the autoload directory under the config directory of the project Configuration file, copy the following content to hyperf.php:

   <?php
   
   declare(strict_types=1);
   
   return [
    'annotations' => [
        'scan' => [
            'paths' => [
                __DIR__ . '/../app'
            ],
        ],
    ],
   ];

3. Start the RPC service
   Execute the following command in the root directory of the project to start the RPC service:

   php bin/hyperf.php start

3. Client calls RPC service

1. Create Http controller
   Create the FilterController.php file in the app/controller directory of the project and add the following Copy the code to FilterController.php:

   <?php
   namespace appcontroller;
   
   use HyperfRpcClientAnnotationRpcClient;
   use HyperfDiAnnotationInject;
   use HyperfHttpServerAnnotationAutoController;
   
   /**
    * @AutoController()
    */
   class FilterController
   {
    /**
     * @RpcClient(name="FilterService")
     */
    protected $filterService;
   
    public function index()
    {
        // 调用RPC服务
        $data = [1, 2, 3, 4, 5];
        $filter = function($item){
            return $item > 3;
        };
        $filteredData = $this->filterService->filterData($data, $filter);
   
        return $filteredData;
    }
   }

2. Routing configuration
   Create a routes.php file in the routes directory under the config directory of the project, and copy the following content to routes. In php:

   <?php
   
   declare(strict_types=1);
   
   use thinkacadeRoute;
   
   Route::get('filter', 'appcontrollerFilterController@index');

3. Test
   Visit http://yourdomain/filter in the browser to see the filtered data.

Summary:
This article introduces how to use ThinkPHP6 and Swoole to develop an efficient RPC service to achieve rapid filtering and processing of data. By configuring the RPC service and calling the RPC client, fast filtering of data in the project is achieved and the filtering results are returned. Hope this article is helpful to you.
