How to use the Hyperf framework for environment configuration management

With the development of business, the environment configuration management of applications has become more and more important. Good configuration management makes it easy to switch between environments and avoids hardcoding sensitive information. The Hyperf framework is a high-performance microservice framework based on Swoole and PHP7. It provides a powerful environment configuration management mechanism that can easily manage the configuration of different environments.

This article will introduce how to use the Hyperf framework for environment configuration management and provide specific code examples.

1. Preparation

First, we need to install the Hyperf framework. It can be installed through Composer:

composer require hyperf/hyperf

After the installation is complete, we can create a new Hyperf project.

2. Configuration file

The Hyperf framework uses the .env file as the configuration file, in which we can define the configuration of different environments. Create an .env file in the root directory with the following content:

APP_NAME=Hyperf
APP_ENV=dev
APP_DEBUG=true

DB_HOST=127.0.0.1
DB_PORT=3306
DB_USERNAME=root
DB_PASSWORD=123456
DB_DATABASE=hyperf

This defines the application name (APP_NAME), operating environment (APP_ENV), database connection information and other configurations. These configurations can be modified according to different environments.

3. Environment Configuration Class

In the Hyperf framework, we can use the Environment class to manage environment configuration. First, we need to create an Environment class, inherit from HyperfContractStdoutLoggerInterface, and implement the HyperfContractStdoutLoggerInterface interface. For example, we can create an Environment class in the app/Service directory with the following content:

<?php

namespace AppService;

use PsrContainerContainerInterface;
use HyperfContractStdoutLoggerInterface;

class Environment implements StdoutLoggerInterface
{
    protected $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function output($messages, $type = self::INFO)
    {
        // 输出日志到控制台
    }

    public function get($key, $default = null)
    {
        // 获取环境变量值
        return env($key, $default);
    }
}

In this class, we use PsrContainerContainerInterface to obtain the application container instance. The Environment class implements the output log method (output) and the method of obtaining the environment variable value (get). Among them, the method of obtaining the environment variable value uses the env() function, which can obtain the configuration in the .env file.

4. Configuration registration

Next, we need to register the Environment class into the Hyperf container. Open the config/autoload/di.php file and add the following code:

return [
    // ...

    HyperfContractStdoutLoggerInterface::class => function () {
        return new AppServiceEnvironment(HyperfUtilsApplicationContext::getContainer());
    },
];

In this way, the Environment class will be registered to the Hyperf container and we can use it elsewhere.

5. Using configuration

Now, we can use the configuration defined in the .env file in the code. Taking database connection as an example, we can use the following code in a controller or other service class to obtain the configuration:

<?php

namespace AppController;

use HyperfDiAnnotationInject;
use HyperfContractStdoutLoggerInterface;

class IndexController extends AbstractController
{
    /**
     * @Inject
     * @var StdoutLoggerInterface
     */
    protected $environment;

    public function index()
    {
        $dbHost = $this->environment->get('DB_HOST');
        $dbPort = $this->environment->get('DB_PORT');
        $dbUsername = $this->environment->get('DB_USERNAME');
        $dbPassword = $this->environment->get('DB_PASSWORD');
        $dbDatabase = $this->environment->get('DB_DATABASE');

        // 使用数据库配置进行连接
    }
}

In this way, we can use the get method of the Environment class to obtain the configuration defined in the .env file, and used in the code.

6. Switch environment

During development and deployment, we need to switch to different environments. The Hyperf framework provides configurations for different environments and defines the APP_ENV variable in the .env file. We can switch the configuration of different environments by modifying the APP_ENV variable in the .env file.

For example, we can change .APP_ENV=dev to APP_ENV=prod to switch to the production environment. Then restart the Hyperf service to load the configuration of the production environment.

Summary:

Through the environment configuration management mechanism of the Hyperf framework, we can easily manage the configuration of different environments and avoid the problem of hard-coding sensitive information. Just define different environment configurations in the .env file, and then use the Environment class to get the configuration. This environment configuration management method is very useful during the development and deployment process, and can greatly improve the flexibility and maintainability of the application.

The above is an introduction and sample code for using the Hyperf framework for environment configuration management. I hope it will be helpful to everyone.
