推荐答案

其实这是pretty容易，你只需要在PHP这样一个小功能：

Actually it's pretty easy, you just need a small function like this in PHP:

function checkPayment($data, $signature)
{
    $base64EncodedPublicKey = "yourBase64PublicKey";
    $openSslFriendlyKey = "-----BEGIN PUBLIC KEY-----\n" . chunk_split($base64EncodedPublicKey, 64, "\n") .  "-----END PUBLIC KEY-----";
    $publicKeyId = openssl_get_publickey($openSslFriendlyKey);

    $result =  openssl_verify ($data, base64_decode($signature), $publicKeyId, OPENSSL_ALGO_SHA1);

    /*
    if ($result == 1) {
        echo "Success";
    } elseif ($result == 0) {
        echo "Verification Failed";
    }
    */

    return $result;
}
