屏蔽ewt的防刷课脚本

似乎已失效 date 2021/8/19
众所周知，当你试图多开ewt的网课时，视频会自动暂停
通过查看源码可知，判断你刷课的标准是检查客户端的Cookie

// 读token Cookie 不解析的
function GetToken(name) {
    var strArg = name + "=";
    var nArgLen = strArg.length;
    var nCookieLen = document.cookie.length;
    var nEnd;
    var i = 0;
    var j;
    while (i < nCookieLen) {
        j = i + nArgLen;
        if (document.cookie.substring(i, j) == strArg) {
            nEnd = document.cookie.indexOf(";", j);
            if (nEnd == -1) nEnd = document.cookie.length;
            if (document.cookie.substring(j, nEnd) == "") return null;
            return unescape(document.cookie.substring(j, nEnd));
        }
        i = document.cookie.indexOf(" ", i) + 1;
        if (i == 0) break;
    }
    return null;
}
