laravel 框架执行流程与原理简单分析(2)

public function make($abstract, array $parameters = []){
  return $this->resolve($abstract, $parameters);
}
public function build($concrete)
// build 中
$reflector = new ReflectionClass($concrete);

class Demo{
  public function store(Request $req333, $abc){
  }
}
class Request{}
$method = new ReflectionMethod('Demo', 'store');
foreach ($method->getParameters() as $parameter) {
  // 获取参数的限制类的类型
  $param_type = $param->getClass(); //获取当前注入对象的类型提示
  $param_value = $param->getName(); //获取参数名称
  if ($param_type) {
    // 通过类的类型限制名称中提取容器中的实例
    $avgs[] = $app[$param_type->name];
  }
}
$reflect->invokeArgs($app['demo'], $avgs);
