yii2笔记： log输出到file及database

2019独角兽企业重金招聘Python工程师标准>>>

编辑config/web.php

首先log要开启

1 2 3

'bootstrap' => [     'log' ],

　　

 

[file]

1 2 3 4 5 6 7 8 9

'components' => [     'log' => [         'targets' => [             [                 'class' => 'yii\log\FileTarget',                 'exportInterval' => 1,             ],         ],     ],

　　

默认输出到runtime/logs/app.log

注意webserver或控制台用户要有写入该文件的权限

 

[database]

1 2 3 4 5 6 7 8

'log' => [     'targets' => [         [             'class' => 'yii\log\DbTarget',             'levels' => ['error', 'warning', 'trace'],         ]     ] ],

 

默认输出db组件对应的数据库下{{%log}}表

 

yii2根目录下运行下面命令生成对应的table schema

1	./yii migrate --migrationPath=@yii/log/migrations/

注意config/console.php下也要有和web.php同样的配置，否则命令执行不成功。

 

还可以根据不同的环境配置不同的日志模式

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

'components' => [     'log' => [         'traceLevel' => YII_ENV == 'dev' ? 3 : 0,         'targets' => [             [                 'class' => 'yii\log\DbTarget',                 'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error'],             ],             [                 'class' => 'yii\log\FileTarget',                 'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error', 'warning'],             ],         ],     ], ],
