为什么我的代币(cookie)没有在浏览器中设置(在MERN堆栈应用程序中使用JWT)?

我在授权登录时发送cookie,但在查看浏览器中存储的cookie时不会显示。发送cookie的代码如下:

app.post('/login', async (req, res) => {
    const { email, password } = req.body;
    
    const user = await User.findOne({email})
    if (!user) {
        return res.status(404).json({message: 'User not found'});
    }
    if (!bcrypt.compareSync(password, user.password)) {
        return res.status(401).json({message: 'Incorrect password'});
    }
    jwt.sign({email:user.email, id:user._id}, process.env.JWT_SECRET, {}, (err, token) => {
        if (err) {
            return res.status(500).json(err);
        }
        res.cookie('token', token).json(user);
    });
    

});

http响应如下所示:

cookie在响应中,但没有被存储,有人知道为什么吗? 我的后端在端口4000,前端在5173,以防有帮助

我尝试过进入隐姓埋名模式,我的代码也有一些变化,比如添加一条路径,但没有成功。
