学习Symfony是一段艰难的旅程，我知道关于SO的帖子会随之而来，所以这是我的问题：经典登录页面，我跟着this tutorial，之前我跟着registration form教程。
注册工作正常，用户使用正确的信息插入数据库，问题是登录，因为无论我尝试过什么，都会弹出无效凭据错误消息，我尝试了多个用户，但没有，我找不到错误，一切似乎都是正确的，我已经检查了很多次。所以，我想时间显示一些代码：
我的登录表单：
<form class="form-horizontal" role="form" method="POST" action="{{ path('login') }}">
...
...
<input type="text" name="_username" class="form-control" id="name"
placeholder="Your username" value="{{ last_username }}" required autofocus>
...
...
<input type="password" name="_password" class="form-control" id="password"
placeholder="Password" required>
<input type="hidden" name="_target_path" value="/admin" />
<input type="hidden" name="_csrf_token" value="{{ csrf_token('authenticate') }}">
我的控制器负责登录：
/**
* @Route("/login", name="login")
*
*/
public function login(Request $request, AuthenticationUtils $authenticationUtils)
{
// get the login error if there is one
$error = $authenticationUtils->getLastAuthenticationError();
// last username entered by the user
$lastUsername = $authenticationUtils->getLastUsername();
return $this->render('main/login.html.twig', array(
'last_username' => $lastUsername,
'error' => $error,
));
}
基本上是教程中的复制粘贴。我已经在我的security.yalm文件中设置了：
security:
# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
providers:
the_user_provider:
entity:
class: App\Entity\User
property: name
encoders:
App\Entity\User:
algorithm: sha512
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
main:
anonymous: ~
# activate different ways to authenticate

# https://symfony.com/doc/current/security.html#a-configuring-how-your-users-will-authenticate
form_login:
login_path: login
check_path: login
csrf_token_generator: security.csrf.token_manager
# https://symfony.com/doc/current/security/form_login_setup.html
provider: the_user_provider
# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
- { path: ^/admin, roles: ROLE_USER }
# - { path: ^/profile, roles: ROLE_USER }
另外，由于我不知道问题是什么，这里是编码用户密码的注册逻辑部分：
public function register(Request $request, UserPasswordEncoderInterface $passwordEncoder, Sluggify $sluggify) {
...
...
// 3) Encode the password (you could also do this via Doctrine listener)
$password = $passwordEncoder->encodePassword($user, $user->getPlainPassword());
$user->setPassword($password);
在我的用户实体中，我已经设置了一个plainPassword和getPlainPassword：
...
...
/**
* @ORM\Column(type="string", length=64)
*/
private $password;
/**
* @Assert\NotBlank()
* @Assert\Length(max=4096)
*/
private $plainPassword;
...
...
public function getPlainPassword()
{
return $this->plainPassword;
}
对于completition，这是 dev.log 文件中的最后一行：

有什么建议吗？我看了一整天的解决方案，我确定这是一个愚蠢的初学者错误，但仍然......没有。
答案 0 :(得分：2)
在这段代码中查看问题：
/**
* @ORM\Column(type="string", length=64)
*/
private $password;
SHA512实际上返回一个长度为128的字符串。因此，简短的答案是，您的字段仅需为128个字符。
您应该将长度设置为128或更大，或者根本不设置长度，默认情况下它将设置为255
/**
* @ORM\Column(type="string")
*/
private $password;
在更改之后，您应该手动或通过迁移来固定数据库表中的字段长度。

我遇到了同样的问题。尝试更改$ user-＆gt; getPlainPassword（）。我相信getPlainPassword是一个表单构建器函数，您已经创建了自己的表单，因此需要将变量与请求对象绑定。
在我的代码中，我这样做了。
$password = $passwordEncoder->encodePassword($user, $params['password']);
/**
* @Route("/register", name="user_registration")
*/
public function registerAction(Request $request, UserPasswordEncoderInterface $passwordEncoder)
{
$params = $request->request->all();
if ($request->isMethod("POST")) {
$user = new User();
$user->setFname($params["fname"]);
$user->setLname($params["lname"]);
$user->setEmail($params["email"]);
$user->setUsername($params["username"]);
$user->setCreatedAt(new \DateTime());
//$user->setPassword($params['password']);
$password = $passwordEncoder->encodePassword($user, $params['password']);
$user->setPassword($password);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($user);
$entityManager->flush();
return $this->redirectToRoute('login');
}
return $this->render(
'default/register.html.twig'
);
}
