如何在Symfony5中创建JWT令牌？

composer require lexik/jwt-authentication-bundle

lexik_jwt_authentication:
    secret_key: '%env(resolve:JWT_SECRET_KEY)%'
    public_key: '%env(resolve:JWT_PUBLIC_KEY)%'
    pass_phrase: '%env(JWT_PASSPHRASE)%'
    token_ttl: 3600

openssl genrsa -out config/jwt/private.pem -aes256 4096
openssl rsa -pubout -in config/jwt/private.pem -out config/jwt/public.pem

JWT_SECRET_KEY=config/jwt/private.pem
JWT_PUBLIC_KEY=config/jwt/public.pem
JWT_PASSPHRASE=your_passphrase

php bin/console make:user

use Lexik\Bundle\JWTAuthenticationBundle\Services\JWTTokenEncoderInterface;

class YourController
{
    private $jwtEncoder;

    public function __construct(JWTTokenEncoderInterface $jwtEncoder)
    {
        $this->jwtEncoder = $jwtEncoder;
    }

    public function generateToken()
    {
        $user = $this->getUser(); // 获取当前用户

        $token = $this->jwtEncoder->encode([
            'username' => $user->getUsername(),
            'roles' => $user->getRoles(),
        ]);

        // 返回生成的令牌
        return new JsonResponse(['token' => $token]);
    }
}
