问题：attempt 方法是自动对password 做哈希运算，如果是不需要做哈希运算验证，怎么处理？谢谢~

public function login(Request $request)
{
    $this->validateLogin($request);
    $credentials = $request->only([$this->username(), 'password']);

    $provider = Auth::getProvider();
    $user = $provider->retrieveByCredentials($credentials);
    if (is_null($user)) {
        return failed('用户不存在', 404);
    }

    // 主要的验证逻辑在这里，这里替换成你想要的逻辑
    if ($provider->validateCredentials($user, $credentials) == false) {
        return failed('认证失败，用户名或密码不正确', 401);
    }

    try {
        if (!$token = $this->guard()->login($user)) {
            return failed('认证失败', 401);
        }
    } catch (JWTException $exception) {
        return internalError('未知错误导致登录失败');
    }

    return success([
        'id' => $user->getAuthIdentifier(),
        'name' => $user->name,
        'email' => $user->email,
        'role_id' => $user->role_id,
        'token_type' => 'Bearer',
        'access_token' => $token,
        'expires_in' => config('jwt.ttl') * 60,
    ]);
