提示这个，怎么处理
$hash = hash_hmac($a,$b,$c);
$github_signa = $_SERVER['HTTP_X_HUB_SIGNATURE'];
list($hash_type, $hash_value) = explode('=', $github_signa, 2);
$payload = file_get_contents("php://input");$secret = '123456';
$hash = hash_hmac($hash_type,$payload,$secret);
if($hash && $hash === $hash_value)
{
echo '认证成功，开始更新';
// echo shell_exec("./github_pull.sh");
echo shell_exec("ifconfig");
echo date("Y-m-d H:i:s");
} 最佳答案
