我可以在 express js 的控制器内使用路由吗？

Question

所以我的一个控制器中有这样的东西：

module.exports.authToken = (req, res, next) => {
    const token = req.cookies.jwt;
    //console.log(token);
    if (!token) {
        return res.sendStatus(403);
    }
    try {
        const data = jwt.verify(token, "secret token");
        console.log(data);
        req.userId = data.id;
        return next();
      } catch {
        return res.sendStatus(403);
      }
  };

它被路由调用：

router.get("/protected", authController.authToken, (req, res) => {
    return res.json({ user: { id: req.userId, role: req.userRole } });
  });

我想在我的其他控制器之一中获得该路由的 JSON 响应。我尝试了一些方法，但都没有成功。

我要做的是将响应抽象为一个函数以供重用：

// the function will just return the data without writing it to the response
function protectedRoute(req) {
    return {user: {id: req.userId, role: req.userRole}};
}

router.get("/protected", authController.authToken, (req, res) => {
    // in the actual handler you can return the response
    return res.json(protectedRoute(req));
});

// make sure the middleware is still being run
router.get("/other_route", authController.authToken, (req, res) => {
    // use the same function to get the response from /protected
    const protectedResponse = protectedRoute(req);
    // do stuff with it
});
