这篇文章主要介绍“Laravel怎么使用Observer实现日志管理模块”，在日常操作中，相信很多人在Laravel怎么使用Observer实现日志管理模块问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”Laravel怎么使用Observer实现日志管理模块”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
写在前面：
这里实现日志管理写了两篇，第一篇是简单的模型增删改监听并记录日志。第二篇主要介绍的是通过导入文件进行批量数据处理无法很好的被监听处理到，这一部分的数据处理逻辑如何被记录下来。详细请看Laravel日志管理记录导入文件后的数据变化。
1、创建observer文件，我这里是要记录仓库库存模块的操作日志，所以执行下面的语句，会在app/Observers下面创建WarehouseInventoryObserver文件。
php artisan make:observer WarehouseInventoryObserver --model=WarehouseInventory由于模型都是放在app/Models下面，所以要指定路径。
php artisan make:observer WarehouseInventoryObserver --model=Models/WarehouseInventory在App\Providers\AppServiceProvider下面开启observer
public function boot() { WarehouseInventory::observe(WarehouseInventoryObserver::class); }2、监听该模块下的增删改操作，这里使用Repository当然也可以直接使用model。created、updated、deleted分别监听WarehouseInventory模型的新增、更新和删除的操作。
<?phpnamespace App\Observers;use App\Models\Warehouse;use App\Models\WarehouseInventory;use App\Repositories\ActionLogRepository;use Illuminate\Support\Arr;use Illuminate\Support\Facades\Auth;class WarehouseInventoryObserver{ protected $user_id; protected $warehouse; protected $actionLogRepository; public function __construct( Warehouse $warehouse, ActionLogRepository $actionLogRepository ) { $this->user_id = Auth::user() ? Auth::user()->id : null; $this->warehouse = $warehouse->pluck('name', 'id'); $this->actionLogRepository = $actionLogRepository; } //创建 public function created(WarehouseInventory $warehouseInventory) { if (!empty($this->user_id)) { $attributes = $warehouseInventory->getAttributes(); $attributes = Arr::only($attributes, ['warehouse_id', 'seller_sku', 'quantity', 'box']); $warehouse = $this->warehouse->get($attributes['warehouse_id']); //拼接数据 $data = [ 'module' => 'warehouse_inventory', 'user_id' => $this->user_id, 'type' => 'create', 'content' => [ 'warehouse' => $warehouse, 'seller_sku' => $attributes['seller_sku'], 'original_quantity' => 0, 'current_quantity' => $attributes['quantity'], 'box' => $attributes['box'] ] ]; $this->actionLogRepository->makeModel()->create($data); } } //更新 public function updated(WarehouseInventory $warehouseInventory) { if (!empty($this->user_id)) { $original = $warehouseInventory->getOriginal(); $dirty = $warehouseInventory->getDirty(); $dirty = Arr::except($dirty, ['remark', 'updated_at']); if (count($dirty)) { if (Arr::has($dirty, 'warehouse_id')) { $warehouse = $this->warehouse->get($dirty['warehouse_id']); } else { $warehouse = $this->warehouse->get($original['warehouse_id']); } //拼接数据 $data = [ 'module' => 'warehouse_inventory', 'user_id' => $this->user_id, 'type' => 'update', 'content' => [ 'warehouse' => $warehouse, 'seller_sku' => $original['seller_sku'], 'original_quantity' => $original['quantity'], 'current_quantity' => $dirty['quantity'], 'box' => (Arr::has($dirty, 'box')) ? $dirty['box'] : $original['box'] ] ]; $this->actionLogRepository->makeModel()->create($data); } } } //删除 public function deleted(WarehouseInventory $warehouseInventory) { if (!empty($this->user_id)) { $original = $warehouseInventory->getOriginal(); $warehouse = $this->warehouse->get($original['warehouse_id']); //拼接数据 $data = [ 'module' => 'warehouse_inventory', 'user_id' => $this->user_id, 'type' => 'delete', 'content' => [ 'warehouse' => $warehouse, 'seller_sku' => $original['seller_sku'], 'original_quantity' => $original['quantity'], 'current_quantity' => 0, 'box' => $original['box'] ] ]; $this->actionLogRepository->makeModel()->create($data); } }}到此，关于“Laravel怎么使用Observer实现日志管理模块”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注编程网网站，小编会继续努力为大家带来更多实用的文章！
