我正在使用带有FOSUserBundle的Symfony2，我想使用Ajax进行用户登录。我使用了一个扩展 DefaultAuthenticationFailureHandler 类的服务：
<?php
namespace Marquis'WebsiteBundle'Handler;
use Psr'Log'LoggerInterface;
use Symfony'Component'Translation'Translator;
use Symfony'Component'HttpFoundation'JsonResponse;
use Symfony'Component'HttpFoundation'Response;
use Symfony'Component'HttpFoundation'RedirectResponse;
use Symfony'Component'HttpFoundation'Request;
use Symfony'Component'HttpKernel'HttpKernelInterface;
use Symfony'Component'Security'Core'Exception'AuthenticationException;
use Symfony'Component'Security'Http'Authentication'DefaultAuthenticationFailureHandler;
use Symfony'Component'Security'Http'HttpUtils;
class AuthenticationFailureHandler extends DefaultAuthenticationFailureHandler {
protected $translator;
public function __construct(HttpKernelInterface $httpKernel, HttpUtils $httpUtils, array $options, LoggerInterface $logger = null, Translator $translator = null) {
parent::__construct($httpKernel, $httpUtils, $options, $logger);
$this->translator = $translator;
}
public function onAuthenticationFailure(Request $request, AuthenticationException $exception) {
if($request->isXmlHttpRequest()) {
/* @var $formResponse RedirectResponse */
$formResponse = parent::onAuthenticationFailure($request, $exception);
$response = new JsonResponse(array('success' => false,
'message' => $this->translator->trans($exception->getMessage(), array(), 'FOSUserBundle'),
'form' => $formResponse->getTargetUrl()));
} else {
$response = parent::onAuthenticationFailure($request, $exception);
}
return $response;
}
}
它运行良好，但我想将渲染的视图转换为"表单"JsonResponse 值。
是否可以从重定向响应对象生成视图？
如果我
理解正确，您想呈现一个视图并在登录或注册页面上显示该视图吗？
如果是这样，你可以直接返回你的视图，从javascript代码中解析为html，并附加到你想要的任何位置。
return $this->twig->render("SampleBundle:sample.html.twig", $data); //$data is not required
您可以像这样将加载的 HTML 附加到您的容器中;
$.ajax({
dataType:"html",
success: function(response){
response.append('#container');
}
});
