自定义Laravel (monolog)日志位置,并增加请求ID的实现

修改 bootstrap/app.php 文件

$app->configureMonologUsing(function($monolog) use ($app) { $monolog->pushHandler(  (new MonologHandlerRotatingFileHandler(   '/var/logs/app/laravel',   $app->make('config')->get('app.log_max_files', 5)  ))->setFormatter(new MonologFormatterLineFormatter(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appProvidersLogServiceProvider.php 文件

修改 configapp.php providers 增加

AppProvidersLogServiceProvider::class

然后 AppProvidersLogServiceProvider.php 内容如下

<?phpnamespace AppProviders;use IlluminateLogLogServiceProvider as SysServiceProvider;use IlluminateLogWriter;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 AppProviders;use IlluminateSupportServiceProvider;use CarbonCarbon;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 MonologHandlerRotatingFileHandler(     $log_file ,     $log_max_files    ))->setFormatter(new MonologFormatterLineFormatter( "[%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 AppProviders;use IlluminateSupportServiceProvider;use MonologFormatterLineFormatter;use MonologHandlerRotatingFileHandler;use CarbonCarbon;use MonologLogger;;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 MonologHandlerRotatingFileHandler  */ 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]; }}
