d 引用的是 cookie.js

https://y.gtimg.cn/music/portal/js/common/music/cookie.js

代码:

define("js/common/music/cookie.js", function(e, t, n) {var o = e("js/common/config.js"),i = {set: function(e, t, n, i, c) {if (c) {var r = new Date;r.setTime(r.getTime() + 36e5 * c)}return document.cookie = e + "=" + escape(t) + "; " + (c ? "expires=" + r.toGMTString() + "; " : "") + (i ? "path=" + i + "; " : "path=/; ") + (n ? "domain=" + n + ";" : "domain=" + o.DCCookieDomain + ";"), !0},get: function(e) {var t;return function(e) {if (!e) return e;for (; e != unescape(e);) e = unescape(e);for (var t = ["<", ">", "'"
