当您进入网站时，设置了cookie，一切正常，但当您重新加载页面时，设置的cookie将被删除
登录响应（back）：

export const sendAccessTokenAndRefreshToken = (response:ServerResponse, accesstoken:string, refreshtoken:string) => {

    response.writeHead(200, {
        'Content-Type': 'text/json; application/json',
        "Access-Control-Allow-Credentials": "true",
        "Access-Control-Allow-Methods": "GET,PUT,POST,DELETE,PATCH,OPTIONS",
        "Access-Control-Allow-Origin": "http://localhost:3000",
        "Access-Control-Allow-Headers": "Access-Control-Allow-Headers, Origin, X-Requested-With, Content-Type, Accept, Authorization",
        'Set-Cookie':  [`refreshtoken=${refreshtoken}; Secure; HttpOnly; SameSite=None; Path=/; Max-Age=99999999;`]
       
    });

    response.end(JSON.stringify({accesstoken}));

}

响应选项（cors）：

response.writeHead(200, {
    'Content-Type': 'text/json; application/json',
    "Access-Control-Allow-Credentials": "true",
    "Access-Control-Allow-Origin": "http://localhost:3000",
    "Access-Control-Expose-Headers": "Authorization",
    "Access-Control-Allow-Headers": "Access-Control-Allow-Headers, Origin, X-Requested-With, Content-Type, Accept, Authorization",
});

response.end(JSON.stringify({message: 'Cors Work!'}));

登录完成后：

站点重新加载后：

在这张图片中，你可以看到当发送一个post请求时，cookie会显示，但是在重新启动后它会消失。

front login.js：

const body = {

    login: login_input.value,
    password: password_input.value

}

fetch('http://127.0.0.1:3000/login', {
    method: 'POST',
    mode: 'cors',
    headers: {
        'Content-Type': 'application/json'
    },
    credentials: 'include',
    body: JSON.stringify(body)
})
.then((response) => response.json())
.then((json) => {
    localStorage.setItem('token', json.accesstoken);

如何解决这一问题？我尝试使用cors浏览器扩展，但即使这样也没有帮助
如何解决这个问题，而不诉诸于无关的框架？
