您有一个错误的缩进来查看问题。。试试这个：
if($request->getMethod()=='POST')
{
$username=$request->get('username');
$password=$request->get('password');
$em=$this->getDoctrine()->getEntityManager();
$repository=$em->getRepository('AppBundle:users');
$user=$repository->findOneBy(array('userName'=>$username, 'password'=>$password));
if($user)
{
return $this->render('default/login.html.twig', array('name' =>$user->getFirstName()));
} else {
return $this->render('default/login.html.twig');
}
} else{
return $this->render('default/login.html.twig');
}
问题是您在POST请求中，但没有用户，所以它不会进入任何返回中。
在这种情况下，我添加了一个要返回的新条件else。
我不知道这个逻辑对你来说是否正确，但问题是
