安装日志系统

日志习题属于框架的一部分,因此在框架目录下执行:

1
composer require monolog/monolog

Logger

在框架 module 下新建 Logger 文件夹用来保存日志相关功能代码,

在 Logger 创建 Log 类:

<?php

namespace FireRabbitEngine\Module\Logger;


use Monolog\Handler\StreamHandler;
use Monolog\Logger;
use Monolog\Formatter\JsonFormatter;

class Log
{
/**
* 日志配置
* @var array
*/
protected static $config;

/**
* 日志对象实例
* @var Logger
*/
protected static $instance = null;

public static function setConfig($config)
{
self::$config = $config;
}

public static function getLogger()
{
if (self::$instance == null) {
self::$instance = new Logger(self::$config['channel']);

if (!file_exists(self::$config['path'])) {
$file = fopen(self::$config['path'], 'w');
fwrite($file, '');
fclose($file);
}

$streamHandler = new StreamHandler(self::$config['path'], self::$config['level']);
// $streamHandler->setFormatter(new JsonFormatter());

self::$instance->pushHandler($streamHandler);
}

return self::$instance;
}
}

setConfig 加载配置参数,getLogger 判断是否存在日志文件,如果没有则创建,同时返回插件包的 Logger。

配置参数

打开 app/config/app.php,添加日志配置:

<?php
$config = [

'view' => [
'view_path' => __DIR__ . '/../view',
'view_cache_path' => __DIR__ . '/../storage/cache/view_cache',
],

'logger' => [
'path' => __DIR__ . '/../storage/logs/log.log',
'level' => \Monolog\Logger::INFO,
'channel' => 'channel-name',
],

'database' => [
'mysql' => [
'driver' => 'mysql',
'host' => 'mysql',
'port' => '3306',
'database' => 'blog',
'username' => 'root',
'password' => '123123',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
],
],
];

return $config;

这里的 view 也被我修改了下,这样看起来更整齐。

加载配置

编辑 http_server.php 加载日志配置:

<?php

date_default_timezone_set("Asia/Shanghai");

require './vendor/autoload.php';
require './firerabbit-engine/vendor/autoload.php';
require_once './app/route/web.php';
require_once './app/config/app.php';

\FireRabbitEngine\Module\Http\Middleware\Kernel::setConfig(require './app/config/middleware.php');
\FireRabbitEngine\Module\View\Blade::setConfig($config['view']['view_path'], $config['view']['view_cache_path']);
\FireRabbitEngine\Module\Database\Manager::setConfig($config['database']['mysql']);

// 新增行
\FireRabbitEngine\Module\Logger\Log::setConfig($config['logger']);

$http = new Swoole\Http\Server('0.0.0.0', 9527);

$http->on('request', function ($request, $response) use ($router) {

var_dump('请求URI:' . $request->server['request_uri']);

$router->handle($request, $response);
});

$http->start();

调用日志

在 IndexController 测试日志是否能正常写入,添加测试代码:

1

<?php
/**
* Created by PhpStorm
* Author:FireRabbit
* Date:2/9/21
* Time:1:17 PM
**/

namespace App\Http\Controller\Home;

use App\Http\Model\User;
use FireRabbitEngine\Module\Controller\Controller;
use FireRabbitEngine\Module\Logger\Log;
use FireRabbitEngine\Module\View\Blade;

class IndexController extends Controller
{
public function index()
{
$user = User::find(1);
$html = Blade::view('index', ['name' => $user->name]);

Log::getLogger()->error('日志');

$this->showMessage($html);
}
}

然后访问首页,可以看到配置日志路径的文件夹下多了一个 log.log:

1
[2021-02-14T14:26:29.828157+08:00] channel-name.ERROR: 日志 [] []

这样日志系统也完成了。
