PHP解密函数：
function decode_cookie($str){
$length = strlen($str);
$newData = "";
$i = 0;
while($i<$length){
$newChar = (hexdec(substr($str,$i,1))<<4) + hexdec(substr($str,$i+1,1));
$newData = $newData.chr($newChar);
$i=$i+2;
}
return $newData;
}
解密后的内容：
��sr1com.bytedance.frameworks.baselib.network.http.b.hXvZ V= Jcxptodin_ttt�abf7bd1286f417061b664cd36d16b8f5a22052c79d4d4fb35cd3adeadc72077153c53e2206b47950d8695f61bd7def04c73f6edfdf3e365e0bb5a6f81d443c1cppt.snssdk.comw&\t/pwze�yux
其中有乱码因为使用了protobuff
abf7bd1286f417061b664cd36d16b8f5a22052c79d4d4fb35cd3adeadc72077153c53e2206b47950d8695f61bd7def04c73f6edfdf3e365e0bb5a6f81d443c1cppt
这部分就是我们需要的内容
