PHP Hyperf microservice development example: Build highly customizable applications

PHP Hyperf is a high-performance framework based on Swoole. It provides a development environment with a microservice architecture, allowing developers to build highly customizable applications. This article will use an example to introduce how to use PHP Hyperf for microservice development.

Before we begin, let’s first understand what microservices are. Microservices is a software architecture style that splits a large application into multiple small services. Each service runs in an independent process and communicates through lightweight communication protocols. The benefits of this architecture are greater scalability, flexibility, and maintainability.

In this example, we will build a simple user management system. The system includes user registration, login, information modification and other functions. We will use Hyperf's microservices framework to build user services and authentication services separately.

First, we need to install Hyperf. It can be installed through Composer. The command is as follows:

composer require hyperf/hyperf

After the installation is completed, we can use Hyperf’s command line tool to create a new project:

php bin/hyperf.php init

Next, we create user services separately and certification services.

First, we create the user service. Create a User directory in the root directory of the project, and create a controller file named UserController.php in that directory. In this file, we define a register method to handle the logic of user registration. The code is as follows:

namespace AppUser;

use HyperfDiAnnotationInject;

class UserController
{
    /**
     * @Inject
     * @var UserService
     */
    private $userService;

    public function register(Request $request)
    {
        $username = $request->input('username');
        $password = $request->input('password');

        $this->userService->register($username, $password);

        return ['code' => 0, 'message' => '注册成功'];
    }
}

Next, we create a class named UserService to handle the specific business logic. In the UserService class, we define a register method to implement the logic of user registration. The code is as follows:

namespace AppUser;

class UserService
{
    public function register($username, $password)
    {
        // TODO: 实现用户注册的逻辑
    }
}

At this point, the user service code is completed.

Next, we create the authentication service. Likewise, create an Auth directory in the root directory of your project, and create a controller file named AuthController.php in that directory. In this file, we define a login method to handle the logic of user login. The code is as follows:

namespace AppAuth;

use HyperfDiAnnotationInject;

class AuthController
{
    /**
     * @Inject
     * @var AuthService
     */
    private $authService;

    public function login(Request $request)
    {
        $username = $request->input('username');
        $password = $request->input('password');

        $token = $this->authService->login($username, $password);

        return ['code' => 0, 'message' => '登录成功', 'token' => $token];
    }
}

Next, we create a class named AuthService to handle the specific business logic. In the AuthService class, we define a login method to implement the user login logic. The code is as follows:

namespace AppAuth;

class AuthService
{
    public function login($username, $password)
    {
        // TODO: 实现用户登录的逻辑
    }
}

At this point, the code for the authentication service is completed.

Next, we need to configure routing. In the root directory of the project, find the config/routes.php file and add the following code to the file:

<?php

use HyperfHttpServerRouterRouter;

Router::addRoute(['GET', 'POST', 'HEAD'], '/user/register', 'AppUserUserController@register');
Router::addRoute(['GET', 'POST', 'HEAD'], '/auth/login', 'AppAuthAuthController@login');

At this point, we have completed the development of microservices. Next, we can start Hyperf's development server to test our application.

In the root directory of the project, run the following command to start the development server:

php bin/hyperf.php start

After successful startup, we can access our interface through a browser or other tools. For example, we can use a tool like Postman to send HTTP requests.

Through the above steps, we successfully built a highly customizable application using PHP Hyperf and realized the development of microservices. By splitting the application into multiple smaller services, we can develop and maintain it more flexibly, and achieve higher scalability.

Summary: This article introduces how to use PHP Hyperf for microservice development through an example. We implemented user services and authentication services by splitting the application into multiple small services, and used Hyperf's routing function to configure interface routing. In this way, we can build a highly customizable application that achieves greater scalability and flexibility. I hope this article can be helpful to everyone.
