阅读rss json项目

嗨，我有这个前端

前端ajaxget

    $.ajax({
        type: "POST",
        "url": "/getfeed",
        success: function (response) {
            console.log(response);

            $.each(response.items, function (k, item) {
                var imgsrc = item.enclosure.link;
                console.log(imgsrc);
                return k <2;
            });

        }
    });

我想循环每个项目以获取其链接、url、标题、发布日期、作者 尝试

它显示

未捕获类型错误：无法读取未定义的属性“title”

有没有合适的方法读出来
