yii2 动态配置日志(log)

Posted 2020-11-04 Chrdai

如果我们在项目中不允许修改配置文件中的 log 组件，那么动态配置 log 就变得很重要了，下面我分享一下动态配置 log 的方法:

public function init()
{
    parent::init();
    Yii::$app->log->targets[0]->levels = [‘info‘, ‘error‘, ‘warning‘]; // only display info ,error and warning
    Yii::$app->log->targets[0]->categories = [‘categoryName‘]; // log category
    Yii::$app->log->targets[0]->logFile = Yii::getAlias(‘@app‘).DIRECTORY_SEPARATOR.‘runtime‘.DIRECTORY_SEPARATOR.‘logs‘.DIRECTORY_SEPARATOR.‘logFileName.log‘; // filePath
    Yii::$app->log->targets[0]->logVars = [‘*‘];  // don‘t display GET,POST,SERVER,COOKIE,SESSION, if config this,display otherwise.
    Yii::$app->log->targets[0]->maxFileSize = 1024 * 2; // maxFileSize=2M
    Yii::$app->log->targets[0]->maxLogFiles = 20;  // maxLogFiles = 20
    
    ...
}
