Yii2-log组件

添加log组件配置

'log' => [
    'traceLevel' => YII_DEBUG ? 3 : 0,
    'targets' => [
        'file' => [
            'class' => 'yii\log\FileTarget',
            'levels' => YII_DEBUG ? ['error','warning','info','trace','profile'] : ['error', 'warning'],
            'categories' => [],
            'logFile' => getenv('LOG_FILE_PATH')?:null,
            'logVars'=> [],
        ],
    ],

],

记录信息Yii::error,Yii::warning,Yii::info等。做开发api时可以在有错误时输出到页面。

$messages = Yii::getLogger()->messages;
print_r($messages);
