修改 bootstrap/app.php 文件

$app->configureMonologUsing(function($monolog) use ($app) { $monolog->pushHandler( (new Monolog\Handler\RotatingFileHandler( '/var/logs/app/laravel', $app->make('config')->get('app.log_max_files', 5) ))->setFormatter(new Monolog\Formatter\LineFormatter(null, null, true, true)) );});

添加以后写入日志文件为：

-rw-r--r-- 1 web web 93 Dec 18 15:52 laravel-2017-12-17-rw-r--r-- 1 web web 279 Dec 18 16:10 laravel-2017-12-18

参考：Laravel 的错误和日志记录

或者

创建app\Providers\LogServiceProvider.php 文件

修改 config\app.php providers 增加

App\Providers\LogServiceProvider::class

然后 App\Providers\LogServiceProvider.php 内容如下

<?phpnamespace App\Providers;use Illuminate\Log\LogServiceProvider as SysServiceProvider;use Illuminate\Log\Writer;class LogServiceProvider extends SysServiceProvider{ protected function configureSingleHandler(Writer $log) { $log->useFiles( '/var/logs/app/laravel.log', $this->logLevel() ); } protected function configureDailyHandler(Writer $log) { $log->useDailyFiles( '/var/logs/app/laravel.log', $this->maxFiles(), $this->logLevel() ); }}

增加请求ID request id

namespace App\Providers;use Illuminate\Support\ServiceProvider;use Carbon\Carbon;class LogServiceProvider extends ServiceProvider{ protected $log_file; /** * Bootstrap any application services. * @return void */ public function boot() { // } /** * Register any application services. * @return void */ public function register() { $this->load_request_id(); $this->log_configure(); } /** * 生成 request_id * @return void */ protected function load_request_id() { define( 'REQUEST_ID' , config('app.log_prefix').Carbon::now()->timestamp ); } /** * 注册 monolog pushHandler * @return void */ protected function log_configure() { $log_file = $this->getLogFile(); $log_max_files = $this->getLogMaxFiles(); /** * @doc https://d.laravel-china.org/docs/5.4/errors#自定义-Monolog-设置 */ $this->app->configureMonologUsing(function($monolog) use ($log_file , $log_max_files) { $monolog->pushHandler( (new \Monolog\Handler\RotatingFileHandler( $log_file , $log_max_files ))->setFormatter(new \Monolog\Formatter\LineFormatter( "[%datetime%] [".REQUEST_ID."] %channel%.%level_name%: %message% %context% %extra%\n", null, true, true)) ); }); } protected function getLogMaxFiles() { return config('app.log_max_files' , 5); } /** * @return mixed */ protected function getLogFile() { if( is_null( $this->log_file) ) { $this->log_file = rtrim(config('app.log_path') , DIRECTORY_SEPARATOR )."/laravel.log"; } return $this->log_file; }}

优化以后

namespace App\Providers;use Illuminate\Support\ServiceProvider;use Monolog\Formatter\LineFormatter;use Monolog\Handler\RotatingFileHandler;use Carbon\Carbon;use Monolog\Logger;;use ReflectionClass;class LogServiceProvider extends ServiceProvider{ protected $log_file; /** * Bootstrap any application services. * * @return void */ public function boot() { // } /** * Register any application services. * * @return void */ public function register() { $this->loadRequestId(); /** * 根据日期来分割日志 */ $this->useDailyFiles(); } protected function loadRequestId() { define( 'REQUEST_ID' , config('app.log_prefix').Carbon::now()->timestamp ); } /** * 根据日期来分割日志 */ protected function useDailyFiles() { $handler = $this->getDailyHandler()->setFormatter( $this->getDefaultFormatter() ); $errorHandler = $this->getDailyHandler(Logger::ERROR)->setFormatter( $this->getDefaultFormatter() ); $this->app->configureMonologUsing( function( $monolog) use ( $handler , $errorHandler ) { $monolog->pushHandler( $handler ); $monolog->pushHandler( $errorHandler ); }); } /** * 设置 日志 行格式 * @return LineFormatter */ protected function getDefaultFormatter() { $format = "[%datetime%] [".REQUEST_ID."] %channel%.%level_name%: %message% %context% %extra%\n"; return new LineFormatter( $format , null, true, true); } /** * 根据日志区分 * @return \Monolog\Handler\RotatingFileHandler */ protected function getDailyHandler( $level = Logger::DEBUG) { return new RotatingFileHandler( $this->logPath().$this->logName( $level ) , $this->maxFiles() , $level ); } /** * 日志文件最多个数 * @return int */ protected function maxFiles() { if ($this->app->bound('config')) { return $this->app->make('config')->get('app.log_max_files', 30); } return 0; } /** * 日志文件名称 * @return mixed */ protected function logPath() { $logPath = $this->app->storagePath()."/logs/"; if( $this->app->bound('config')) { $logPath = $this->app->make('config')->get('app.log_path', $logPath ); } return $logPath; } /** * log 完整文件名 * @param int $level * @return string */ protected function logName( $level = Logger::DEBUG ) { return $this->getAppName().'-'.$this->getLevelName( $level ).".log"; } /** * 获取项目app * @return mixed */ protected function getAppName() { return $this->app->make('config')->get('app.name'); } /** * 获取log错误级别名称 * @param $level * @return mixed */ protected function getLevelName( $level ) { $r = new ReflectionClass( Logger::class ); $constants = array_flip( $r->getConstants() ); return $constants[$level]; }}

以上这篇自定义Laravel (monolog)日志位置,并增加请求ID的实现就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
