一，相关文档:
https://learnku.com/docs/laravel/10.x/container/14842二，php代码:
假设我们有两种商品：虚拟商品如账号，实体商品如手办需要销售
1,App\extend\mall\GoodsInterface.php
| 1 2 3 4 5 6 7 |
<?php
namespace App\extend\mall;
//接口
interface GoodsInterface
{
public function sale();
}
|
2,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/>';
}
}
|
3,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/>';
}
}
|
4,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();
}
}
|
5，routes/web.php中添加:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
Route::get('container/test', function(){
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);
});
|
6,相关说明:
上面的代码：通过saleOne方法的参数把对象注入进来，
app()：用来生成容器。
bind(): 直接绑定一个容器对象。
instance()：绑定一个实例化对象。
singleton(): 绑定一个单例对象。
绑定完成之后，make() 方法来获得容器中的对象实例
三，查看效果:
四，查看laravel框架的版本:
liuhongdi@lhdpc:/data/laravel/dignews$ php artisan --version
