How to use the Hyperf framework to build a microservice architecture

Introduction:
With the popularity of microservice architecture, more and more developers are beginning to look for suitable A framework for building microservices. Hyperf is an ultra-high-performance framework based on Swoole and PHP, suitable for large and complex microservice applications. This article will introduce in detail how to use the Hyperf framework to build a microservice architecture and provide specific code examples.

1. Environment preparation
   Before starting, make sure that the server has PHP and Swoole extensions installed and meets the requirements of the Hyperf framework. You can check it with the following command:

php -v

php --ri swoole

2. Install the Hyperf framework
   Use Composer to install the Hyperf framework, execute the following command:

composer create-project hyperf/hyperf-skeleton

Waiting for installation Once completed, go to the root directory of the Hyperf project.

3. Create microservices
   The Hyperf framework uses service providers (Service Providers) to manage application components and extensions. To create a new microservice, you can generate a service provider template by running the following command:

php bin/hyperf.php gen:provider <ProviderName>

Replace <ProviderName> with the service provider's according to actual needs Name, such as OrderProvider.

The generated service provider class file will be saved in the app/Provider directory. Open the file and you can see a typical service provider template:

<?php

declare(strict_types=1);

namespace AppProvider;

use HyperfContractStdoutLoggerInterface;
use thinkApp;
use thinkContainer;
use thinkexceptionHandle;
use thinkRequest;
use thinkResponse;
use HyperfContractConfigInterface;
use HyperfContractContainerInterface;
use HyperfContractRequestInterface;
use HyperfContractResponseInterface;
use HyperfContractServerInterface;
use HyperfDiContainer as HyperfContainer;
use HyperfHttpServerRequest as Psr7Request;
use HyperfHttpServerResponse as Psr7Response;
use HyperfHttpServerServer;
use PsrContainerContainerInterface as PsrContainerInterface;

class OrderProvider implements HyperfContractServiceProviderInterface
{
    public function register(ContainerInterface $container)
    {
        // 注册服务逻辑
    }

    public function getConfig(ContainerInterface $container): array
    {
        return [];
    }
}

In the register method, you can write the registration logic of the service, such as binding the service to the container and configuring routing wait.

4. Configuring microservice routing
   In the created service provider, you can configure routing by calling the method of the Router class. The following is an example just to illustrate usage:

<?php

declare(strict_types=1);

namespace AppProvider;

use HyperfContractStdoutLoggerInterface;
use HyperfDiContainer;
use HyperfUtilsApplicationContext;
use HyperfContractContainerInterface;
use HyperfHttpServerRouterRouter;
use HyperfHttpServerRouterDispatcherFactory;

class OrderProvider implements HyperfContractServiceProviderInterface
{
    public function register(ContainerInterface $container)
    {
        // 注册服务逻辑

        $router = $container->get(Router::class);

        $router->addRoute(['GET', 'POST'], '/order', function ($request) {
            // 处理订单请求的逻辑
        });

        $router->addRoute(['GET', 'POST'], '/order/{id:d+}', function ($request, $id) {
            // 处理订单详情请求的逻辑
        });
    }

    public function getConfig(ContainerInterface $container): array
    {
        return [];
    }
}

In the above example, we add routing rules through the addRoute method of the Router class . Among them, ['GET', 'POST'] indicates that GET and POST requests are supported, /order and /order/{id:d} respectively indicate orders. Routing path for list and order details. It can be configured according to actual needs.

5. Run Hyperf application
   To run Hyperf application, you can execute the following command:

php bin/hyperf.php start

After the application starts, you can access it through a browser or other HTTP tools The routing path of the microservice. For example, visit http://localhost:9501/order to view the order list.

Summary:
This article briefly introduces how to use the Hyperf framework to build a microservice architecture, and provides specific code examples. By following the above steps, developers can quickly build microservice applications based on Hyperf and implement complex business logic. Hope this article can be helpful to you.
