从Jwt Token检索数据- Flutter和Symfony

我正在开发一个连接到Symfony API的Flutter应用程序。身份验证后,我需要从令牌中检索连接到应用程序的用户的数据。
问题:我可以检索用户的角色,它是User类的属性(字符串数组)。但是,我不能为其他属性这样做。我测试了令牌是否包含密钥,结果显示它不包含除“roles”之外的任何密钥。
我将分享端点symfony、我的用户类、Flutter的登录以及如何从token检索角色
端点Symfony:

class AuthController extends AbstractController
{
    private $doctrine;
    private $jwtManager;

    
    public function __construct(ManagerRegistry $doctrine, JWTTokenManagerInterface $jwtManager) 
    {
        $this->doctrine = $doctrine;
        $this->jwtManager = $jwtManager;

    }

    /**
     * @Route("/api/login_check", name="app_login_check", methods={"POST"})
     */
    public function loginCheck(Request $request, UserPasswordHasherInterface $passwordEncoder): JsonResponse
    {
        $data = json_decode($request->getContent(), true);

        $cin = $data['cin'] ?? '';
        $password = $data['password'] ?? '';

        $user = $this->doctrine->getRepository(Utilisateur::class)->findOneBy(['cin' => $cin]);

        if (!$user || !$passwordEncoder->isPasswordValid($user, $password)) {
            throw new BadCredentialsException('Invalid cin or password');
        }

        $token = $this->jwtManager->create($user);

        return new JsonResponse(['token' => $token]);
    }

}

List<String> getUserRolesFromToken(String jwtToken) {

你正在使用this bundle来生成jwt。但是,这个库只使用rolesusername(默认)来生成jwt有效负载。
如果您想添加自定义字段,请参考this article
prefs.setString是Future,所以必须使用setString使用await

await prefs.setString('token', token);
