symfony angularjs登录后InsufficientAuthenticationException

我在客户端上的服务器和Angularjs上有symfony和doctrine.我想创建一个Login Endpoint.登录正在运行,我得到一个PHPSESSID Cookie.

登录后我执行后续请求.在这个要求我得到一个
InsufficientAuthenticationException：

Full authentication is required to access this resource. (500 Internal Server Error)

后续请求的标题：

我不知道我的错误在哪里,或者我如何调试这个问题.

编辑：
用PHP登录：

/**
     * @Route("/login",name="login")
     * @param Request $request
     * @return Response
     */
    public function login(Request $request)
    {
        $securityContext = $this->container->get('security.authorization_checker');
//        $tokenStorage = $this->container->get('security.token_storage');
//        $token = $tokenStorage->getToken();
//        var_dump($token);  => user has not Token!
        if ($securityContext->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
            return new Response('http://localhost/frontend/admin/');
        } else {
            return new Response('',500);
        }
    }

在JS中：

<script type="text/javascript">
    $( "#loginForm" ).submit(function( event ) {
        event.preventDefault();
        let $form = $(this);
        let username = $form.find( "input[name='username']" ).val();
        let password = $form.find( "input[name='password']" ).val();
        let data = "{";
        data += '"username": "'+username+'",';
        data += '"password": "'+password+'" ';
        data += "}";

        $.ajax({
            method: 'post',url:'http://localhost/symfony/public/login',type:"POST",data:data,contentType:"application/json; charset=utf-8"
            //dataType:"json"
        }).done(function(response) {
            $(location).attr('href',response)
        }).fail(function() {
        });
    });
</script>
