Cookie 未在前端 React js 中设置，但在 Postman 中有效

Question

I am making a full stack ecommerece website but when i login the backend send an object containing token , success message and user details but the thing to access the other function i have made an isVerified function which gets the token from cookie and checks it , i have tested all the function in Postman and they were working but in frontend they are not working as they keep saying req.cookie.token undefined
 I want that token to be stored in cookie in frontend and be accesible

使用的技术是React Js，Express js 浏览器是Chrome 我已经尝试了一切请有人帮助我 我尝试使用 secure 删除 ，将 http 从 true 设置为 false 使用 cors 设置应用程序并使用凭证 true ，

   // Code 
   Login function in Frontend
    
   
       const handleSubmit = async (e) => {
               e.preventDefault();
               const user = { email, password };
               const response = await login(user);
               if (response.error) {
                   console.error('Login error:', response.error);
       
               } else {
       
                   Cookies.set('token', response.token, { expires: 7, sameSite: 'lax' });
                   setUser(response.user);
                   console.log('Login successful:', response);
                   navigate('/');
               }
       
           };
   Auth middleware in backend 
   const isVerified = async (req, res, next) => {
     const token = req.cookies.token;
     console.log(token);
   
     if (!token) {
       return next(new ErrorHandler("Login first to access this resource", 401));
     }
     const decoded = jwt.verify(token, process.env.JWT_SECRET);
     req.user = await User.findById(decoded.id);
     next();
   };
   // Util send token function
   // Creating a token and sending it in a cookies
   const sendToken = (user, statusCode, res) => {
     const token = user.getJwtToken();
   
     const options = {
       expires: new Date(
         Date.now() + process.env.COOKIE_EXPIRES_TIME * 24 * 60 * 60 * 1000
       ),
       httpOnly: false,
     };
   
     res.status(statusCode).cookie("token", token, options).json({
       success: true,
       token,
       user,
     });
   };
   module.exports = sendToken;

只是猜测，但可能是因为您的请求中没有包含凭据。 Mdn

fetch("https://example.com", {
  credentials: "include",
});

您还可以使用 DevTools -> 应用程序选项卡 -> Cookies 检查客户端是否设置了 cookie。

此外，可能需要调整服务器上的 cookie 配置。
