一，相关文档:
https://learnku.com/docs/laravel/10.x/providers/14843二，php代码：
1,业务代码:
App\extend\mall\GoodsInterface.php
| 1 2 3 4 5 6 7 |
<?php
namespace App\extend\mall;
//接口
interface GoodsInterface
{
public function sale();
}
|
App\extend\mall\RealGoods.php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 |
<?php
namespace App\extend\mall;
//实体商品
class RealGoods implements GoodsInterface
{
private $name = '';
public function __construct($name) {
$this->name = $name;
}
public function sale() {
echo '实体商品:'.$this->name. '下订单,减库存,通知发货<br/>';
}
}
|
App\extend\mall\VirtualGoods.php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?php
namespace App\extend\mall;
//虚拟商品
class VirtualGoods implements GoodsInterface
{
private $name = '';
public function __construct($name) {
$this->name = $name;
}
public function sale() {
echo '虚拟商品:'.$this->name. '下订单,无需减库存,生成虚拟商品并通知用户<br/>';
}
}
|
App\extend\mall\GoodsSale.php
| 1 2 3 4 5 6 7 8 9 |
<?php
namespace App\extend\mall;
//销售功能
class GoodsSale
{
public function saleOne(GoodsInterface $goods) {
$goods->sale();
}
}
|
2，创建服务提供者
liuhongdi@lhdpc:/data/laravel/dignews$ php artisan make:provider GoodsServiceProvider
INFO Provider [app/Providers/GoodsServiceProvider.php] created successfully.
liuhongdi@lhdpc:/data/laravel/dignews$ php artisan make:provider GoodsSaleServiceProvider
INFO Provider [app/Providers/GoodsSaleServiceProvider.php] created successfully.3，服务提供者的代码:
app/Providers/GoodsServiceProvider.php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class GoodsServiceProvider extends ServiceProvider
{
/**
* Register services.
*/
public function register(): void
{
//
$this->app->bind('RealGoods', function(){
return new \App\extend\mall\RealGoods('手办');
});
$this->app->bind('VirtualGoods', function(){
return new \App\extend\mall\VirtualGoods('账号');
});
}
/**
* Bootstrap services.
*/
public function boot(): void
{
//
}
}
|
app/Providers/GoodsSaleServiceProvider.php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class GoodsSaleServiceProvider extends ServiceProvider
{
/**
* Register services.
*/
public function register(): void
{
//
$this->app->singleton('GoodsSale', function(){
return new \App\extend\mall\GoodsSale();
});
}
/**
* Bootstrap services.
*/
public function boot(): void
{
//
}
}
|
4，把服务提供者注册到config/app.php中:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
'providers' => ServiceProvider::defaultProviders()->merge([
/*
* Package Service Providers...
*/
/*
* Application Service Providers...
*/
App\Providers\AppServiceProvider::class,
App\Providers\AuthServiceProvider::class,
// App\Providers\BroadcastServiceProvider::class,
App\Providers\EventServiceProvider::class,
App\Providers\RouteServiceProvider::class,
//以下为我们自定义的provider
App\Providers\GoodsServiceProvider::class,
App\Providers\GoodsSaleServiceProvider::class,
])->toArray(),
|
5，在routes/web.php中添加代码:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
Route::get('container/test', function(){
/*
原来绑定service的代码放到了provider中,
所以注释掉了
app()->bind('RealGoods', function(){
return new \App\extend\mall\RealGoods('手办');
});
app()->instance('VirtualGoods', new \App\extend\mall\VirtualGoods('账号'));
app()->singleton('GoodsSale', function(){
return new \App\extend\mall\GoodsSale();
});
*/
$goodsSale = app()->make('GoodsSale');
$rgoods = app()->make('RealGoods');
$goodsSale->saleOne($rgoods);
$vgoods = app()->make('VirtualGoods');
$goodsSale->saleOne($vgoods);
});
|
三，测试效果:
四，查看laravel框架的版本:
liuhongdi@lhdpc:/data/laravel/dignews$ php artisan --version
Laravel Framework 10.27.0
