这篇文章主要介绍了Yii使用DbTarget实现日志功能的示例代码,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧。
一:在配置文件的log组件中配置DbTarget
- 'log' => [
- 'traceLevel' => YII_DEBUG ? 3 : 0,
- 'targets' => [
- [
- 'class' => 'yii\log\FileTarget',
- 'levels' => ['error', 'warning'],
- ],
- 'test' => [
- 'class' => 'yii\log\DbTarget',//DaTarget类
- 'logTable' => '{{%test_log}}',//日志表
- 'levels' => ['error', 'info', 'warning'],//日志等级
- ],
- ],
- ],
二:生成日志表
在项目目录下执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:自定义DbTarget日志
1:首先创建一个自定义的日志表
(1)在项目目录下执行
php yii migrate/create create_test_log
(2):在创建的migrate文件下编写创建数据库的迁移脚本
- <?php
- 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('日志等级'),
- 'category' => $this->string(100)->notNull()->comment('分类名称'),
- 'prefix' => $this->text(),
- 'route' => $this->string(100)->notNull()->comment('路由'),
- 'method' => $this->string(20)->notNull()->comment('请求方式'),
- 'app' => $this->string(20)->comment('请求应用'),
- 'module' => $this->string(20)->comment('请求模块'),
- 'request' => $this->text()->comment('请求参数'),
- 'status' => $this->string(10)->notNull()->comment('状态码'),
- 'message' => $this->text()->comment('日志内容'),
- 'request_at' => $this->double()->notNull()->comment('请求时间'),
- 'ip' => $this->string(63)->comment('请求IP'),
- ], 'CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE=InnoDB COMMENT=\'请求日志表\'');
- //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):执行如下命令生成DbTarget日志表
php yii migrate
2:编写一个DbTarget类来继承yiilogDbTarget类
- <?php
- 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 用户组件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();
- $ip = emptyempty($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!');
- }
- }
- /**
- * 获取当前IP
- */
- protected function getIp()
- {
- $request = Yii::$app->getRequest();
- return $request instanceof Request ? $request->getUserIP() : '';
- }
- }
3:在配置文件中将yiilogDbTarget类改成我们自定义的类
- '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
同样的使用Yii::info来记录日志
