res.redirect 在使用 React 时不起作用

Question

I am using react as frontend and made api using express I have the following code I have stored jwt token in the cookies while logging in for the first then when trying to login in again I check if there is already a token in the cookies if there is token in the cookie (currently I am not verifying it I just want it to work) redirect the user to profile page but it doesn't work. Although an XMLHttpRequest can be seen in the network tab ( click for screenshot ) but it doesn't work. PS - I am using Axios in the frontend to make a get request.

loginRouter.get("/", async (req, res) => {
  try {
    const cookieFound = req.cookies["login-token"];
    if (cookieFound) {
      res.redirect("profile");
    } else {
      res.redirect("login");
    }
    
  } catch (error) {
    console.log(error);
    res.status(500).json("Ooops something went wrong!");
  }
});

code to make a get request in the frontend

useEffect(() => {
    Axios.get("/login");
  }, []);

EDIT:-

Backend

 loginRouter.get("/", async (req, res) => {
  try {
    const cookieFound = req.cookies["login-token"];
    if (cookieFound) {
      res.send("/profile");
    }
    // res.status(200).json(cookieFound);
  } catch (error) {
    console.log(error);
    res.status(500).json("Ooops something went wrong!");
  }
});

Client

    useEffect(() => {
    const alreadyLoggedIn = async () => {
      const url = await Axios.get("/login");

      window.location = url.data;
    };
    alreadyLoggedIn();
  }, []);

To what you have entered I think you should change window.location = url.data to window.location = window.location.hostname + url.data; In your current setup the total url will be set to /profile while you want yourwebsite.com/profile
