关于 php:drupal 8 使用控制器渲染模板树枝的错误

drupal 8 error to render template twig with controller

我正在尝试使用我的控制器渲染模板但不起作用
它告诉我这个错误：

LogicException: The controller must return a response (

Hello Bob! given). in Symfony//Component//HttpKernel//HttpKernel->handleRaw() (line 163 of core/vendor/symfony/http-kernel/Symfony/Component/HttpKernel/HttpKernel.php).

我的功能：

1
2
3
4
5

public function helloAction($name) {
$twigFilePath = drupal_get_path(‘module’, ‘acme’) . ‘/templates/hello.html.twig’;
$template = $this->twig->loadTemplate($twigFilePath);
return $template->render(array(‘name’ => $name));
}

在 Drupal 8 中，您可以从控制器返回 Response 对象或渲染数组。所以你有两个选择：

1) 将渲染的模板放入一个 Response 对象中：

1
2
3
4
5
6

public function helloAction($name) {
$twigFilePath = drupal_get_path(‘module’, ‘acme’) . ‘/templates/hello.html.twig’;
$template = $this->twig->loadTemplate($twigFilePath);
$markup = $template->render(array(‘name’ => $name));
return new Response($markup);
}

2) 将渲染后的模板放入渲染数组中：

1
2
3
4
5
6
7
8

public function helloAction($name) {
$twigFilePath = drupal_get_path(‘module’, ‘acme’) . ‘/templates/hello.html.twig’;
$template = $this->twig->loadTemplate($twigFilePath);
$markup = $template->render(array(‘name’ => $name));
return array(
‘#markup’ => $markup,
);
}

class ClientController extends ControllerBase implements ContainerInjectionInterface ,ContainerAwareInterface {

protected $twig ;

public function __construct(//Twig_Environment $twig)
{
$this->twig = $twig ;
}

public function index()
{

$twigFilePath = drupal_get_path(‘module’, ‘client’) . ‘/templates/index.html.twig’;
$template = $this->twig->loadTemplate($twigFilePath);
$user = [‘user’ => ‘name’] ; // as example
$markup = [
‘#markup’ => $template->render( [‘users’ => $users ,‘kit_form’ => $output] ),
‘#attached’ => [‘library’ => [‘client/index.custom’]] ,
];
return $markup;

}

// this is called first then call constructor
public static function create(ContainerInterface $container)
{
return new static(
$container->get(‘twig’) ,
);
}
}

这个通过控制器的依赖注入渲染树枝的完整示例

你也可以使用没有自定义模板的第二个选项，这样做：

1
2
3
4
5
6

public function helloAction($name) {
$markup ="<p> Without custom Template</p>";
return array(
‘#markup’ => $markup,
);
}
