Мобильная версияМой API дает правильный ответ с помощью почтальона.
Я проверил буквально все, что я получаю, это пустой массив сеансов, кстати, моя аутентификация работает нормально. Я проверил маршрут, порт, они все правильные.
Фронтенд → GET http://localhost:8080/api/sessions
Бэкенд → ответы 404 не найден, я не почему
http://localhost:8080/api/sessions это маршрут
и это ответ

Если кому-то интересно узнать мой серверный API
app.use("/api/sessions", sessionRoutes);
это sessionRoute
router.get("/", protect, getMySession);
это контроллер
export const getMySession = async (req, res) => {
try {
const sessions = await Session.find({ user: req.user._id }) //
corrected: find all, not findById.sort({ createdAt: -1 })
.populate("questions");
if (!sessions || sessions.length === 0) {
return res.status(404).json({ message: "No sessions found" });
}
return res.status(200).json({ sessions });
} catch (error) {
console.error("Error fetching sessions:", error);
return res
.status(500)
.json({ message: "Error fetching sessions", error: error.message });
}
};
это промежуточное ПО для аутентификации
import jwt from "jsonwebtoken";
import User from "../model/User.js";
export const protect = async (req, res, next) => {
// 1. Read the token from the cookie
const token = req.cookies.jwt;
if (!token) {
// Unauthorized (401) if no token is present
return res.status(401).json({ message: "Not authorized, no token provided." });
}
try {
// 2. Verify the token (jwt.verify throws on failure: expired, invalid signature, etc.)
const decoded = jwt.verify(token, process.env.JWT_SECRET);
// 3. Find the user attached to the token
const user = await User.findById(decoded.userId).select("-password");
if (!user) {
// Unauthorized (401) if token is valid but user no longer exists
return res.status(401).json({ message: "Not authorized, user no longer exists." });
}
// 4. Attach user object to the request
req.user = user;
// 5. Continue to the next middleware/controller
next();
} catch (error) {
// Handles errors thrown by jwt.verify (e.g., token expired, invalid signature)
// Log the actual error on the backend for debugging
console.error("JWT verification failed:", error.message);
return res.status(401).json({ message: "Not authorized, token failed verification." });
}
