《PHP教程:Laravel日志用法詳解》要點(diǎn):
本文介紹了PHP教程:Laravel日志用法詳解,希望對(duì)您有用。如果有疑問(wèn),可以聯(lián)系我們。
PHP教程本文實(shí)例講述了Laravel日志用法.分享給大家供大家參考,具體如下:
PHP教程這里使用的Laravel版本仍是5.2
PHP教程日志是非常重要的.本地開發(fā)可以開啟調(diào)試模式,但是上線的項(xiàng)目查看日志是非常簡(jiǎn)潔有效的調(diào)試手段.Laravel集成了Monolog日志庫(kù)以便提供多種功能強(qiáng)大的日志處理器.
PHP教程Laravel支持日志方法single, daily, syslog 和 errorlog.例如,如果你想要日志文件按日生成而不是生成單個(gè)文件,應(yīng)該在配置文件config/app.php中設(shè)置log值如下:
PHP教程
'log' => 'daily'
PHP教程系統(tǒng)默認(rèn)配置為single
PHP教程
#config/app.php:111
'log' => env('APP_LOG', 'single'),
PHP教程下面我們看下Laravel是如何配置日志的.
PHP教程
#vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php:36
protected $bootstrappers = [
'Illuminate\Foundation\Bootstrap\DetectEnvironment',
'Illuminate\Foundation\Bootstrap\LoadConfiguration',
'Illuminate\Foundation\Bootstrap\ConfigureLogging',
'Illuminate\Foundation\Bootstrap\HandleExceptions',
'Illuminate\Foundation\Bootstrap\RegisterFacades',
'Illuminate\Foundation\Bootstrap\RegisterProviders',
'Illuminate\Foundation\Bootstrap\BootProviders',
];
<?php
namespace Illuminate\Foundation\Bootstrap;
use Illuminate\Log\Writer;
use Monolog\Logger as Monolog;
use Illuminate\Contracts\Foundation\Application;
class ConfigureLogging
{
/**
* Bootstrap the given application.
*
* @param \Illuminate\Contracts\Foundation\Application $app
* @return void
*/
public function bootstrap(Application $app)
{
$log = $this->registerLogger($app);
// If a custom Monolog configurator has been registered for the application
// we will call that, passing Monolog along. Otherwise, we will grab the
// the configurations for the log system and use it for configuration.
if ($app->hasMonologConfigurator()) {
call_user_func(
$app->getMonologConfigurator(), $log->getMonolog()
);
} else {
$this->configureHandlers($app, $log);
}
}
PHP教程如果自定義Monolog配置,走if條件,默認(rèn)走else
PHP教程
protected function configureHandlers(Application $app, Writer $log)
{
$method = 'configure'.ucfirst($app['config']['app.log']).'Handler';
$this->{$method}($app, $log);
}
/**
* Configure the Monolog handlers for the application.
*
* @param \Illuminate\Contracts\Foundation\Application $app
* @param \Illuminate\Log\Writer $log
* @return void
*/
protected function configureSingleHandler(Application $app, Writer $log)
{
$log->useFiles(
$app->storagePath().'/logs/laravel.log', #存儲(chǔ)文件
$app->make('config')->get('app.log_level', 'debug') #存儲(chǔ)級(jí)別
);
}
PHP教程這里useFiles方法是注冊(cè)signle文件日志處理程序,并設(shè)置存儲(chǔ)文件以及存儲(chǔ)的級(jí)別.
PHP教程下面是初始化日志時(shí)的4種日志處理注冊(cè)方式.
PHP教程
public function useFiles($path, $level = 'debug') #單一文件
public function useDailyFiles($path, $days = 0, $level = 'debug') #每日生成
public function useSyslog($name = 'laravel', $level = 'debug') #系統(tǒng)日志的方式
public function useErrorLog($level = 'debug', $messageType = ErrorLogHandler::OPERATING_SYSTEM) #等同于php的error_log方式
PHP教程日志初始化信息基本上就是上面這些.
PHP教程你可以使用Log門面編寫日志信息到日志中:
PHP教程八種日志級(jí)別:emergency, alert, critical, error,warning, notice, info 和 debug.
PHP教程
Log::emergency($error);
Log::alert($error);
Log::critical($error);
Log::error($error);
Log::warning($error);
Log::notice($error);
Log::info($error);
Log::debug($error);
