我怎么能用yii2获取日志消息

Question

i have a little problem. I'm developing a php application using Yii2 framework and i want to save a log messagges into db table. I'm coding my own component witch extends DbTarget, in this component i rewrite export() function to save data into my table. It's works fine, but i can't get the log message. For example, when i call Yii:log('message log'), all my data are saved in my db except 'message log' because i don't know how to get this value in my component.

Any solutions? thanks

P.s. I'm newbee with yii2 and i have read the official documentation, but i didn't find any solution.

It seems you should specify level of the message

Yii:log('message log', Logger::LEVEL_TRACE);

or use shortcut methods

Yii::info('message log');
Yii::trace('message log');
Yii::error('message log');

Check your config for another targets. May be your message goes to level or category of another target. Notice that default category is 'application'.

To be shure you can make this configuration

'components' => [
    'log' => [
        'targets' => [
            [
                'class' => 'YourDbTarget',
                'levels' => ['info'],
                'categories' => ['application'],
            ],
        ],
    ],
],

And try to log info message

Yii::info('message log'); // target = info, category = application
