[QQ]G_TK算法

Note:根據js分析得到QQ空間的g_tk算法

Note:獲取到cookie,判斷cookie中是否有p_skey,沒有使用skey;點擊傳送到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:根據cookie獲取到g_tk;
