在 Slim 2 中,我可以轻松地覆盖默认的 404 页面,
// @ref: http://help.slimframework.com/discussions/problems/4400-templatespath-doesnt-change
$app->notFound(function () use ($app) {
$view = $app->view();
$view->setTemplatesDirectory('./public/template/');
$app->render('404.html');
});
但在《超薄3》中,
// ref: http://www.slimframework.com/docs/handlers/not-found.html
//Override the default Not Found Handler
$container['notFoundHandler'] = function ($c) {
return function ($request, $response) use ($c) {
return $c['response']
->withStatus(404)
->withHeader('Content-Type', 'text/html')
->write('Page not found');
};
};
如何添加我的 404 模板('404.html')?
创建您的容器:
// Create container
$container = new \Slim\Container;
// Register component on container
$container['view'] = function ($c) {
$view = new \Slim\Views\Twig('./public/template/');
$view->addExtension(new \Slim\Views\TwigExtension(
$c['router'],
$c['request']->getUri()
));
return $view;
};
//Override the default Not Found Handler
$container['notFoundHandler'] = function ($c) {
return function ($request, $response) use ($c) {
return $c['view']->render($response->withStatus(404), '404.html', [
"myMagic" => "Let's roll"
]);
};
};
构建\Slim\App
对象使用$container
并运行:
$app = new \Slim\App($container);
$app->run();
