一：在配置文件的log組件中配置DbTarget

'log' => [

'traceLevel' => YII_DEBUG ? 3 : 0,

'targets' => [

[

'class' => 'yii\log\FileTarget',

'levels' => ['error', 'warning'],

],

'test' => [

'class' => 'yii\log\DbTarget',//DaTarget類

'logTable' => '{{%test_log}}',//日志表

'levels' => ['error', 'info', 'warning'],//日志等級

],

],

],

二：生成日志表

在項目目錄下執行如下命令生成日志表

php yii migrate --migrationPath=@yii/log/migrations/

三：使用日志

在需要使用日志的地方使用

Yii::info()

四：自定義DbTarget日志

1：首先創建一個自定義的日志表

(1)在項目目錄下執行

php yii migrate/create create_test_log

(2)：在創建的migrate文件下編寫創建數據庫的遷移腳本

use yii\db\Migration;

/**

* Class m200720_091126_create_test_log

*/

class m200720_091126_create_test_log extends Migration

{

/**

* {@inheritdoc}

*/

public function safeUp()

{

$this->createTable('{{%test_log}}', [

'id' => $this->bigPrimaryKey(),

'level' => $this->integer()->notNull()->comment('日志等級'),

'category' => $this->string(100)->notNull()->comment('分類名稱'),

'prefix' => $this->text(),

'route' => $this->string(100)->notNull()->comment('路由'),

'method' => $this->string(20)->notNull()->comment('請求方式'),

'app' => $this->string(20)->comment('請求應用'),

'module' => $this->string(20)->comment('請求模塊'),

'request' => $this->text()->comment('請求參數'),

'status' => $this->string(10)->notNull()->comment('狀態碼'),

'message' => $this->text()->comment('日志內容'),

'request_at' => $this->double()->notNull()->comment('請求時間'),

'ip' => $this->string(63)->comment('請求IP'),

], 'CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE=InnoDB COMMENT=\'請求日志表\'');

//增加索引

$this->createIndex('idx_log_level', '{{%test_log}}', 'level');

$this->createIndex('idx_log_category', '{{%test_log}}', 'category');

$this->createIndex('idx_log_route', '{{%test_log}}', 'route');

$this->createIndex('idx_log_method', '{{%test_log}}', 'method');

$this->createIndex('idx_log_status', '{{%test_log}}', 'status');

}

/**

* @inheritdoc

*/

public function safeDown()

{

$this->dropTable('{{%test_log}}');

}

}

(3)：執行如下命令生成DbTarget日志表

php yii migrate

2：編寫一個DbTarget類來繼承yiilogDbTarget類

namespace app\components;

use Yii;

use yii\helpers\VarDumper;

use yii\log\LogRuntimeException;

use yii\web\HttpException;

use yii\web\Request;

/**

* DbTarget stores log messages in a database table.

*

* @see yii\log\DbTarget

*

* @author wangjian

* @since 1.0

*/

class DbTarget extends \yii\log\DbTarget

{

/**

* @inheritdoc

*/

public $categories = [

'application',

'yii\web\HttpException:*',

];

/**

* @inheritdoc

*/

public $except = [

// 'yii\web\HttpException:404',

];

/**

* @inheritdoc

*/

public $logVars = ['_GET', '_POST'];

/**

* @var string 用戶組件ID

*/

public $userComponentId = 'user';

/**

* @inheritdoc

*/

public function collect($messages, $final)

{

$this->messages = array_merge($this->messages, static::filterMessages($messages, $this->getLevels(), $this->categories, $this->except));

$count = count($this->messages);

if ($count > 0 && ($final || $this->exportInterval > 0 && $count >= $this->exportInterval)) {

$oldExportInterval = $this->exportInterval;

$this->exportInterval = 0;

$this->export();

$this->exportInterval = $oldExportInterval;

$this->messages = [];

}

}

/**

* @inheritdoc

*/

public function getMessagePrefix($message)

{

if ($this->prefix !== null) {

return call_user_func($this->prefix, $message);

}

if (Yii::$app === null) {

return '';

}

$ip = $this->getIp();

$ip = empty($ip) ? '-' : $ip;

return "[$ip]";

}

/**

* @inheritdoc

*/

public function export()

{

if ($this->db->getTransaction()) {

$this->db = clone $this->db;

}

$tableName = $this->db->quoteTableName($this->logTable);

$sql = "INSERT INTO $tableName ([[level]], [[category]], [[prefix]], [[route]], [[method]], [[app]], [[module]], [[request]], [[status]], [[message]], [[request_at]], [[ip]])

VALUES (:level, :category, :prefix, :route, :method, :app, :module, :request, :status, :message, :request_at, :ip)";

$command = $this->db->createCommand($sql);

$request = Yii::$app->getRequest();

list($route, $params) = $request->resolve();

$method = $request->getMethod();

$module = Yii::$app->controller->module->id;

$route = str_replace("{$module}/", '', $route);

foreach ($this->messages as $message) {

list($text, $level, $category, $timestamp) = $message;

$statusCode = 200;

if (!is_string($text)) {

if ($text instanceof \Throwable || $text instanceof \Exception) {

$statusCode = $text instanceof HttpException ? $text->statusCode : 500;

$text = $text->getMessage();

} else {

$text = VarDumper::export($text);

}

}

if ($command->bindValues([

':level' => $level,

':category' => $category,

':prefix' => $this->getMessagePrefix($message),

':route' => $route,

':method' => $method,

':app' => Yii::$app->id,

':module' => $module,

':request' => $this->getContextMessage(),

':status' => $statusCode,

':message' => $text,

':request_at' => $timestamp,

':ip' => $this->getIp(),

])->execute() > 0) {

continue;

}

throw new LogRuntimeException('Unable to export log through database!');

}

}

/**

* 獲取當前IP

*/

protected function getIp()

{

$request = Yii::$app->getRequest();

return $request instanceof Request ? $request->getUserIP() : '';

}

}

3：在配置文件中將yiilogDbTarget類改成我們自定義的類

'log' => [

'traceLevel' => YII_DEBUG ? 3 : 0,

'targets' => [

[

'class' => 'yii\log\FileTarget',

'levels' => ['error', 'warning'],

],

'test' => [

'class' => 'app\components\DbTarget',

'logTable' => '{{%test_log}}',

'levels' => ['error', 'info', 'warning'],

],

],

],

4：使用DbTarget日志

同樣的使用Yii::info來記錄日志
