>什么是中间件
`中间件主要用于编织从 请求(Request) 到 响应(Response) 的整个流程，通过对多个中间件的组织，使数据的流动按我们预定的方式进行`
生成中间件
```
php ./bin/hyperf.php gen:middleware Middleware1
php ./bin/hyperf.php gen:middleware Middleware2
```
middleware1.php
```
container = $container;
}
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
echo 'middleware1'.PHP_EOL;
return $handler->handle($request);
}
}
```
middleware2.php
```
container = $container;
}
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
echo 'middleware2'.PHP_EOL;
return $handler->handle($request);
}
}
```
配置路由
```
[Middleware1::class,Middleware2::class]]);
```
创建控制器
```
