关于yii2 的db log 日志 错误处理errorHandler

log 

通过配置Web.config来完成 

1 数据库增加 ‘前缀_log’表

2 配置Web.config 

'bootstrap' => ['log'],
'components' =>[
'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0, //级别
            'targets' => [ 
                'file' => [  //使用文件存储日志
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ],
                'legcc' =>[  //自定义模式 [例如发邮件、微信等]
                    'class' => 'app\components\LegccLogTarget',
                    'levels' => ['error', 'warning'],
                    'categories' => [
                        'yii\db\*',

                    ],
                    'except' => [
                        'yii\web\HttpException:404',
                    ],
                    'logVars' => [],

 邮件采用  yii\swiftmailer\Mailer

参考官网

http://www.yiiframework.com/doc-2.0/yii-log-target.html
http://www.cnblogs.com/yhdsir/p/5896820.html

备注 :yii migrate --migrationPath=@yii/log/migrations/ 需要进行数据库表的迁移

errorHandler:
参考
yii\base\Exception;
http://blog.csdn.net/dasgk/article/details/52180696

如果在web/index.php中defined('YII_DEBUG') or define('YII_DEBUG', true);
可以采用 可以在web.php中对excepiton的属性exceptionView重新定义 eg:
'components' => [
'errorHandler' => [
'errorAction' => 'site/error',
'exceptionView'=>'@app/views/site/error_exceptionView.php'
],
]
如果 设置为false ,直接调转到site/error的页面,在该页面可以通过excepiton的get方法获取相关内容。
