不完全确定是什么导致了这个问题，特别是因为我已经遵循了官方文档。我还在这里阅读了无数的 Google Group 讨论和问题，但无济于事。
所以我一直在 Fabien Potencier 的Silex Skeleton之上构建我的应用程序，但是我的单元测试在使用 FormServiceProvider 的页面上失败了。

There was 1 error:
1) Acme\AppEngineTest::testAppControllerForm

在 controllers.php 中，我安装了一个包含表单的控制器
use Acme\Controller\FacebookAppControllerProvider;
$app->mount('/app/', new FacebookAppControllerProvider());
看起来像这样
<?php
namespace Acme\Controller;
use Silex\Application;
use Silex\ControllerProviderInterface;
use Silex\Provider\FacebookServiceProvider;
use SlotMachine\Page as PageContainer;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Yaml\Yaml;
class FacebookAppControllerProvider implements ControllerProviderInterface
{
public function connect(Application $app)
{
if (! $app['twig']->hasExtension('silex_asset_path')) {
throw new \OutOfBoundsException(
'The `silex_asset_path` Twig extension provided by this library has not been registered.'
);
}
// creates a new controller based on the default route
$controllers = $app['controllers_factory'];
$app->register(new FacebookServiceProvider(), [
'facebook.config' => [
'appId' => '1',
'secret' => '2',
'sharedSession' => true,
'trustForwarded' => true,
'fileUpload' => false
],
'facebook.permissions' => [ 'email' ],
]);
$app['facebook_app.widget_data'] = [
'foo' => [
'name' => 'Foo'
],
'bar' => [
'name' => 'Bar'
]
];
$controllers->match('/', function (Application $app) {
return $app->render("facebook_app/index.html.twig", $app['facebook_app.widget_data']);
})->method('POST|GET');
$controllers->match('/app/{widget}/{tp}', function (Request $request, Application $app, $widget, $tp) {
$slots = new PageContainer(Yaml::parse(BASEPATH.'/src/Acme/Resources/config/'.$widget.'.slots.yml'));
// some default data for when the form is displayed the first time
$formData = [
'forename' => 'First-Name',
'surname' => 'Last-Name',
'telephone' => 'Telephone',
];
$form = $app->form($formData)
->add('forename', 'text', [ 'label' => 'Name' ])
->add('surname', 'text', [ 'label' => false ])
->add('telephone')
->getForm()
; //end
if ('POST' == $request->getMethod()) {
$form->bind($request);
if ($form->isValid()) {
$data = $form->getData();
// do something with the data
// redirect somewhere
return $app->redirect('/');
}
}
$pageData = [
'slot' => $slots->all(),
'template_number' => $tp,
'widget' => [
'slug' => $widget,
'name' => $app['facebook_app.widget_data'][$widget]['name']
],
'form' => $form->createView(),
];
foreach ($pageData['slot'] as $slot => &$card) {
$card = PageContainer::interpolate($card, [
'widget_name' => $pageData['widget']['name']
]);
}
$app['page_data'] = $pageData;
return $app->render(sprintf('templates/%s/template_%d.html.twig', $widget, $tp), $app['page_data']);
})
->method('POST|GET')
->assert('tp', '\d+')
->value('tp', 1)
; // end /app/{publication}/{tp} Controller
return $controllers;
}
}
在 app.php 中，FormServiceProvider 在实例化一个新的 Silex 应用程序之后以及在添加 Twig 扩展之前立即注册。
$app['twig'] = $app->share($app->extend('twig', function($twig, $app) {
// add custom globals, filters, tags, ...
$twig->addExtension(new Acme\Twig\SilexAssetPathExtension($app));
return $twig;
}));
