發現好多小夥伴除錯程式碼時對sql 列印不方便,特整理怎麼實時在日誌檔案中列印所執行的 sql 語句
1、在 Listeners
目錄新建 QueryListener.php
檔案 程式碼如下:
<?php
namespace App\Listeners;
use Illuminate\Database\Events\QueryExecuted;
class QueryListener
{
public function handle(QueryExecuted $event)
{
if (env('APP_ENV', 'production') == 'local') {
$sql = str_replace('?', "'%s'", $event->sql);
$log = vsprintf($sql, $event->bindings);
$this->put_log('sql', $log);
}
}
private function put_log($file = 'app', $content = '')
{
$data = date('Y-m-d');
$cut_line = str_repeat("-", 100);
is_dir(storage_path('logs/sql')) or mkdir (storage_path('logs/sql'), 0777, true); // 資料夾不存在則建立
$content = '[' . date('Y-m-d H:i:s') . "]" . $content;
@file_put_contents(storage_path('logs/sql/' . $file . '-' . $data . '.log'), $content . "\n" . $cut_line . "\n\n", FILE_APPEND);
}
}
2、在Providers/EventServiceProvider.php
新增如下程式碼
<?php
namespace App\Providers;
use Laravel\Lumen\Providers\EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
'Illuminate\Database\Events\QueryExecuted' => [
'App\Listeners\QueryListener'
],
];
}
3、在 bootstrap/app.php
檔案中開啟 EventServiceProvider
註冊即可
$app->register(App\Providers\EventServiceProvider::class);
4、接下來寫一個 sql 語句就能在 storage/logs/sql
看到生成的 sql
日誌了
app('db')->where('id', '>', '5')->get();
希望能對大家有所幫助
