Laravel 开启sql调试

​

1.在config/database.php添加以下内容

'enableQueryLog' => env('ENABLE_QUERY_LOG',false),

2.打开app\Providers\AppServiceProvider.PHP，在boot方法中添加如下内容

use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\DB;

public function boot()
    {
        if (config('database.enableQueryLog')) {
            DB::listen(
                function ($sql) {
                    foreach ($sql->bindings as $i => $binding) {
                        if ($binding instanceof \DateTime) {
                            $sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
                        } else {
                            if (is_string($binding)) {
                                $sql->bindings[$i] = "'$binding'";
                            }
                        }
                    }

                    // Insert bindings into query
                    $query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);

                    $query = vsprintf($query, $sql->bindings);
                    Log::info('查询语句耗时 - ' . $sql->time . ' 毫秒 ', [
                        '链接名称' => $sql->connectionName,
                        'Sql语句' => $query
                    ]);
                }
            );
        }
    }
