使用AJAX解决，

错误是我从 js 文件中获取API，无法到达我的"Cookies"并返回

The Error was my fetch API from js file, couldn't reach my "Cookies" and return

options.AccessDeniedPath ="/account/accessdenied"; 在

services.ConfigureApplicationCookie .

当我调试 notification.js 响应对象是

response = Response {type: "cors", url: "{mysite}.com/account/login?ReturnUrl=%2Fapi%2Fnotifications", redirected: true, status: 200, ok: true, …}

如果将您的 Cookie 设置为 HttpOnly = true ，那么您将使它们无法从 client 辅助脚本访问.

If you set your Cookies to HttpOnly=true then you are making them unreachable from client side scripts.

因此，我在 .script 标签中的 .cshtml 下直接进行了Ajax调用，而我的Ajax调用是:

So, I've made an Ajax call directly under my .cshtml in a script tag and my Ajax call was:

function notifyUser() {
        var ul = document.getElementById("notification-list");
        ul.innerHTML = "";
        var notificationDropdownBtn = document.getElementById("notification-dropdown");
        var initialNotificationLimit = 2;

        notificationDropdownBtn.onclick = () => {
            notifyUser();
        }

        $.ajax({
            type: "GET",    

            //In here I directly use my controller and action.        
            url: "@Url.Action("Notifications", "Portal")",
            contentType: "application/json",
            dataType: "json",
            success: function (notifications) {

            var unreadNotifications = notifications.filter(notification => !notification.isRead);

            if (unreadNotifications.length > 0) {
                ...
            } else {
                ...
            },
            error: function (req, status, error) {
                console.error(error);
            }
        });
    }
