Question

我正在使用 LexikJWTAuthenticationBundle 来生成json令牌，我的问题是我在验证用户是否在BD后不知道如何生成令牌。我能帮忙吗？

我的代码。

            your_ref.addListenerForSingleValueEvent(new ValueEventListener()     {
             @Override
            public void onDataChange(DataSnapshot dataSnapshot) {


            songslist= new ArrayList<String>();

            Toast.makeText(DataFromFirebase.this, "number of songs are " + dataSnapshot.getChildrenCount(), Toast.LENGTH_LONG).show();
            //String value = (String) dataSnapshot.getValue();
                sizetemp=dataSnapshot.getChildrenCount();
            // Result will be holded Here
            for (DataSnapshot dsp : dataSnapshot.getChildren()) {
                songslist.add(String.valueOf(dsp.getKey())); //add result into array list

            //NOW YOU HAVE ARRAYLIST WHICH HOLD RESULTS




        }

        @Override
        public void onCancelled(DatabaseError firebaseError) {

        }


    });

My Utilizador Class

 public function postLoginAction(Request $request)
    {
        $user = new Utilizador();
        $json = json_decode($request->getContent(), true);
        $user->setUser($json['user']);
        $user->setPass($json['pass']);
        $em = $this->getDoctrine()->getManager();
        $existuser = $em->getRepository('RestBundle:Utilizador')->findOneBy(array(
            'user' => $user->getUser(),
            'pass' => $user->getPass()
        ));
        if($existuser)
    {
        $token =  $this->get('lexik_jwt_authentication.jwt_manager')->create($user);
        return new JsonResponse(['token' => $token]);
    }

    }

Answer 1

以下是如何从有效的安全用户：

创建令牌

$token = $this->get('lexik_jwt_authentication.jwt_manager')->create($user);

您可以直接尝试，但我想这对您不起作用，因为您的用户实体看起来非常自定义要使其有效，您的用户实体必须实现Symfony\Component\Security\Core\User\UserInterface。

为此，您应该真正配置实体用户提供程序，而不是通过实体管理器手动从控制器加载用户。见How to load security users from the database

希望这能帮助你以正确的方式前进。

以下是一个完整的示例，说明了从数据库加载用户并使用此捆绑包对用户进行身份验证所需执行的操作：
