|
## 安装
|
||
|
|
~~~

composer require topthink/think-container
|
||
|
|
~~~
|
||
|
|
|
||
|
|

|
||
|
|
* 支持PSR-11规范
|
||
|
|
* 支持依赖注入
|
||
|
|
* 支持Facade门面
|
||
|
|
* 支持容器对象绑定
|
||
|
|
* 支持闭包绑定
|
||
|
|
* 支持接口绑定
|
||
|
|
|
||
|
|
## Container
|
||
|
|
~~~
|
||
|
|
// 获取容器实例
|
||
|
|
$container = \think\Container::getInstance();
|
||
|
|
// 绑定一个类、闭包、实例、接口实现到容器
|
||
|
|
$container->bind('cache', '\app\common\Cache');
|
||
|
|
// 判断是否存在对象实例
|
||
|
|
$container->has('cache');
|
||
|
|
// 从容器中获取对象的唯一实例
|
||
|
|
$container->get('cache');
|
||
|
|
// 从容器中获取对象，没有则自动实例化
|
||
|
|
$container->make('cache');
|
||
|
|
// 删除容器中的对象实例
|
||
|
|
$container->delete('cache');
|
||
|
|
// 执行某个方法或者闭包 支持依赖注入
|
||
|
|
$container->invoke($callable, $vars);
|
||
|
|
// 执行某个类的实例化 支持依赖注入
|
||
|
|
$container->invokeClass($class, $vars);
|
||
|
|
// 静态方法获取容器对象实例 不存在则自动实例化
|
||
|
|
\think\Container::pull('cache');
|
||
|
|
~~~
|
||
|
|
|
||
|
|
对象化操作
|
||
|
|
~~~
|
||
|
|
// 获取容器实例
|
||
|
|
$container = \think\Container::getInstance();
|
||
|
|
// 绑定一个类、闭包、实例、接口实现到容器
|
||
|
|
$container->cache = '\app\common\Cache';
|
||
|
|
// 判断是否存在对象实例
|
||
|
|
isset($container->cache);
|
||
|
|
// 从容器中获取对象的唯一实例
|
||
|
|
$container->cache;
|
||
|
|
// 删除容器中的对象实例
|
||
|
|
unset($container->cache);
|
||
|

## Facade
|
||
|
|
|
||
|
|
|
||
|
|
定义一个`app\facade\App`类之后，即可以静态方式调用`\think\App`类的动态方法
|
||
|
|
~~~
|
||
|
|
<?php
|
||
|
|
namespace think;
|
||
|
|
class App
|
||
|
|
{
|
||
|
|
public function name(){
|
||
|
|
return 'app';
|
||
|
|
}
|
||
|
|
}
|
||
|
|
~~~
|
||
|
|
|
||
|
|
~~~
|
||
|
|
<?php
|
||
|
|
namespace app\facade;
|
||
|
|
|
||
|
|
use think\Facade;
|
||
|
|
|
||
|
|
class App extends Facade
|
||
|
|
{
|
||
|
|
/**
|
||
|
|
* 获取当前Facade对应类名
|
||
|
|
* @access protected
|
||
|
|
* @return string
|
||
|
|
*/
|
||
|
|
protected static function getFacadeClass()
|
||
|
|
{
|
||
|
|
return '\think\App';
|
||
|
|
}
|
||
|
|
}
|
||
|
|
~~~
|
||
|
|
|
||
|
|
然后就可以静态方式调用动态方法了
|
||
|
|
~~~
|
||
|
|
use app\facade\App;
|
||
|
|
|
||
|
|
echo App::name(); // app
|
||
|
|
~~~
