[QQ]G_TK算法

Note:根据js分析得到QQ空间的g_tk算法

Note:获取到cookie,判断cookie中是否有p_skey,没有使用skey;点击传送到JS

function getToken(c) {
    var obj = JSON.parse("{\"" + c.replace(/=/g,"\":\"").replace(/; /g,"\",\"") + "\"}");
    var v = obj.p_skey || obj.skey;
    var t = 5381;
    for (var r = 0, o = v.length; r < o; ++r) {
        t += (t << 5) + v.charAt(r).charCodeAt();
    }
    return t & 2147483647;
}

Note:根据cookie获取到g_tk;
