使用中间件更改cakephp 3的请求

Question

我正在尝试实现一个中间件，该中间件将从 API 读取数据并稍后在控制器上使用它。怎么能做到这一点？我制作了一个简单的中间件

public function __invoke(ServerRequestInterface $request, ResponseInterface $response, $next)
{
    $dataFromApi = curl_action....
    $request->dataFromApi = $dataFromApi;
    return next($request, $response);
}

稍后我想在控制器上使用

访问这些数据

public function display(...$path)
{
    $this->set('dataFromApi', $this->request->dataFromAPI);
}

Answer 1

查看 \Psr\Http\Message\ServerRequestInterface API，您可以使用 ServerRequestInterface::withAttribute():

将自定义数据存储在属性中

// ...
// request objects are immutable
$request = $request->withAttribute('dataFromApi', $dataFromApi);
// ...
return next($request, $response);

并通过 ServerRequestInterface::getAttribute():

相应地读入你的控制器

$this->set('dataFromApi', $this->request->getAttribute('dataFromApi'));

另见

PHP-FIG > PSR-7 > Psr\Http\Message\ServerRequestInterface
