Yii日志记录Logging

1、Yii::getLogger()->log($message, $level, $category = ‘application‘)
2、Yii::trace($message, $category = ‘application‘);
3、Yii::error($message, $category = ‘application‘);
4、Yii::warning($message, $category = ‘application‘);
5、Yii::info($message, $category = ‘application‘);

 components->log

默认配置：
‘log‘=> [
            ‘traceLevel‘ => YII_DEBUG ? 3 : 0,
            ‘targets‘ => [
                [
                    ‘class‘ => ‘yii\log\FileTarget‘,
                    ‘levels‘ => [‘error‘, ‘warning‘],
                ],
            ],
        ],

‘log‘ => [
            ‘traceLevel‘=> YII_DEBUG ? 3 : 0,
            ‘targets‘ => [
                [
                    ‘class‘ => ‘yii\log\FileTarget‘,
                    ‘levels‘ => [‘error‘, ‘warning‘,‘info‘,‘trace‘],
                ],
                [
                    ‘class‘=> ‘yii\log\FileTarget‘,
                    ‘levels‘ => [‘info‘],
                    ‘categories‘ => [‘rhythmk‘],
                    ‘logFile‘ => ‘@app/runtime/logs/Mylog/requests.log‘,
                    ‘maxFileSize‘ => 1024 * 2,
                    ‘maxLogFiles‘ => 20,
                ],
            ],
        ],

Yii::getLogger()->log("开始写自定义日志",Logger::LEVEL_ERROR);

Yii::trace("trace,开发调试时候记录");

Yii::error("error,错误日志");

Yii::warning("warning,警告信息");

Yii::info("info,记录操作提示");

  Yii::info("info .... ","rhythmk");//输出自定义目录日志,@app/runtime/logs/Mylog/requests.log
