php - Symfony2 AuthenticationCredentialsNotFoundException @Route

Question

AuthenticationCredentialsNotFoundException in classes.php line 2876:

The token storage contains no authentication token. One possible reason may be that there is no firewall configured for this URL.

我尝试了所有可以在 Stack Overflow、GitHub 和 Google 上找到的东西。没有任何效果。

经验教训:始终检查日志文件。

tail -f app/logs/dev.log

发现这个:

...[Semantical Error] The annotation \"@Route\" in method Ambry\TumorNextAPIBundle\Controller\DefaultController::indexAction() was never imported. Did you maybe forget to add a \"use\" statement for this annotation?...

我错过了以下使用语句:

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

在以下代码中:

<?php

namespace Ambry\TumorNextAPIBundle\Controller;

use Symfony\Component\HttpFoundation\Request;

use Ambry\BioToolsBundle\Controller\ApplicationController;

class DefaultController extends ApplicationController
{
    /**
     * @Route("/", name="tumornext" )
     * @Method({"GET","POST"})
     * @Template
     */
    public function indexAction(Request $request)
    {
        return array();
    }
}

经验教训:始终检查日志文件。

tail -f app/logs/dev.log
tail -f app/logs/dev.log | grep CRIT
tail -f app/logs/dev.log | grep ERROR
tail -f app/logs/dev.log | grep INFO

在这种情况下，您缺少 use 语句:

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
