如何处理从Nuxt SSR进行的护照js重定向？

我在快速会话中使用Nuxt SSR，并且我从服务器端重定向了护照JS

/**
 * POST /signup
 * Create a new local account.
 */
exports.postSignup = (req, res, next) => {
  const validationErrors = [];
  if (!validator.isEmail(req.body.email)) validationErrors.push({ msg: 'Please enter a valid email address.' });
  if (!validator.isLength(req.body.password, { min: 8 })) validationErrors.push({ msg: 'Password must be at least 8 characters long' });
  if (req.body.password !== req.body.confirmPassword) validationErrors.push({ msg: 'Passwords do not match' });

  if (validationErrors.length) {
    req.flash('errors', validationErrors);
    return res.redirect('/signup');
  }
  req.body.email = validator.normalizeEmail(req.body.email, { gmail_remove_dots: false });

  const user = new User({
    email: req.body.email,
    password: req.body.password
  });

  User.findOne({ email: req.body.email }, (err, existingUser) => {
    if (err) { return next(err); }
    if (existingUser) {
      req.flash('errors', { msg: 'Account with that email address already exists.' });
      return res.redirect('/signup');
    }
    user.save((err) => {
      if (err) { return next(err); }
      req.logIn(user, (err) => {
        if (err) {
          return next(err);
        }
        res.redirect('/');
      });
    });
  });
};

如果我调用重定向方法？它将重新加载页面并清除Vuex状态，对吗？我该如何从护照重定向，以使Vuex状态保持不变且客户端页面不刷新
