hyperf/logger 组件是基于 psr/logger 实现的，默认使用 monolog/monolog 作为驱动，在 hyperf-skeleton 项目内默认提供了一些日志配置，默认使用 Monolog\Handler\StreamHandler, 由于 Swoole 已经对 fopen, fwrite 等函数进行了协程化处理，所以只要不将 useLocking 参数设置为 true，就是协程安全的。

安装composer包

composer require hyperf/logger

• 配置文件：config/autoload/logger.php 可以配置日志位置,格式例如年月日,以及日志等级

<?php

return [
    'default' => [
        'handler' => [
            'class' => \Monolog\Handler\StreamHandler::class,
            'constructor' => [
                'stream' => BASE_PATH . '/runtime/logs/hyperf.log',
                'level' => \Monolog\Logger::DEBUG,
            ],
        ],
        'formatter' => [
            'class' => \Monolog\Formatter\LineFormatter::class,
            'constructor' => [
                'format' => null,
                'dateFormat' => null,
                'allowInlineLineBreaks' => true,
            ]
        ],
    ],
];

使用：在构造函数中实例对象

<?php
namespace App\Controller;

use App\Exception\ResourceException;
use Hyperf\HttpServer\Annotation\AutoController;
use Hyperf\HttpServer\Annotation\Middleware;
use Hyperf\HttpServer\Annotation\Middlewares;

class IndexController extends AbstractController
{
    /**
     * @var \Psr\Log\LoggerInterface
     */
    protected $logger;

    public function __construct(\Hyperf\Logger\LoggerFactory $loggerFactory)
    {
        $this->logger = $loggerFactory->get('log', 'default');
    }

    public function index()
    {
        $this->logger->info('hello world');
    }
}

使用：封装Log类

<?php
namespace App\Controller;

use App\Exception\ResourceException;
use Hyperf\HttpServer\Annotation\AutoController;
use Hyperf\HttpServer\Annotation\Middleware;
use Hyperf\HttpServer\Annotation\Middlewares;

class IndexController extends AbstractController
{
    /**
     * @var \Psr\Log\LoggerInterface
     */
    protected $logger;

    public function index()
    {
        $this->logger = \Hyperf\Utils\ApplicationContext::getContainer()
            ->get(\Hyperf\Logger\LoggerFactory::class)
            ->get('log', 'default');
        $this->logger->info('hello world');
    }
}
