How to use the Hyperf framework for cache management

Cache is one of the important means to improve application performance, and modern frameworks provide us with more convenient cache management tools. This article will introduce how to use the Hyperf framework for cache management and provide specific code examples.

Hyperf framework is a high-performance framework based on Swoole expansion and development. It has a rich set of built-in components and tools, including powerful cache management functions. The Hyperf framework supports a variety of cache drivers, such as Redis, Memcached, etc., and provides a simple API and flexible configuration options to facilitate developers to manage cache according to actual needs.

First, we need to install the Hyperf framework and related dependencies in the project. For specific installation steps, please refer to Hyperf official documentation. After the installation is complete, we can start using Hyperf for cache management.

1. Configuring the cache driver

In the Hyperf framework, we can specify the cache driver to use through the configuration file. Create the cache.php file in the config/autoload directory and configure it as follows:

<?php

return [
    'default' => [
        'driver' => HyperfUtilsCoroutine::inCoroutine() ? 'redis' : 'array',
        'pack' => HyperfContractNormalizerInterface::class,
        'options' => [
            'prefix' => 'your_prefix:', // 缓存前缀
            'ttl' => 3600, // 缓存时间
            'serialize' => true, // 是否序列化缓存值
            'data_compress' => false, // 是否压缩缓存值
        ],
        'cache_pool' => 'default',
        'is_default_pool' => true,
    ],

    'redis' => [
        'driver' => HyperfCacheDriverRedisDriver::class,
        'pack' => HyperfContractNormalizerInterface::class,
        'options' => [
            'prefix' => 'your_prefix:',
            'pool' => 'default',
            'ttl' => 3600,
            'serialize' => true,
            'data_compress' => false,
        ],
    ],
];

In the above configuration file, we specified the default cache drive as Redis, which can also be modified to other drives as needed. At the same time, we can also set the cache prefix, expiration time, whether to serialize the cache value and other options.

2. Using the cache service

Next, use the cache service for cache management in our code. The Hyperf framework provides the Cache component for cache management operations. We can obtain an instance of the cache service through the following code:

<?php

use HyperfDiAnnotationInject;
use HyperfCacheAnnotationCacheable;
use HyperfCacheAnnotationCacheEvict;
use PsrSimpleCacheCacheInterface;

class CacheService
{
    /**
     * @Inject
     * @var CacheInterface
     */
    private $cache;
    
    /**
     * @Cacheable(prefix="user:", ttl=3600)
     */
    public function getUserInfo(int $userId)
    {
        // 查询用户信息的逻辑
    }
    
    /**
     * @CacheEvict(prefix="user:")
     */
    public function clearUserInfoCache(int $userId)
    {
        // 清除用户信息缓存的逻辑
    }
}

In the above code, we first annotate a method for caching through the @Cacheable annotation, which includes the cache prefix and expiration time. When calling this method, if the corresponding data exists in the cache, the cached data will be returned directly; otherwise, the internal logic of the method will be executed and the result will be cached.

The @CacheEvict annotation is used to annotate a method for clearing the cache. When this method is called, all cached data under the corresponding cache prefix will be cleared.

Through the above sample code, we can flexibly use the cache management function of the Hyperf framework to improve the performance and response speed of the application.

Summary

Through the cache management function of the Hyperf framework, we can easily perform cache operations and select the appropriate cache driver according to actual needs. In project development, making full use of the cache function can effectively improve application performance and user experience. I hope this article is helpful to you, thank you for reading!
