我有树桌

ID    A

1     10

ID    B
-----------
1     20
2     30

ID    C
-----------
2     40
3     50

任何人都可以告诉如何制作视图或查询这样的打印件？

ID     A      B      C      R (A + B - C)
-----------------------------------
1     10     20      0     30
2      0     30     40    -10
3      0      0     50    -50

提前致谢.

我正在尝试在我的远程php服务器上的app billing v3中验证android.

但是,我的代码似乎有些不对劲.

我认为这个openssl_verify函数是个问题.

结果总是失败!

我找不到用openssl_verify验证的第一个参数.实际上,我混淆了第一个参数放置的合理格式:(

你能帮我解决一下吗？

    $result = openssl_verify($data["purchaseToken"], base64_decode($signature), $key); // original // failed

低于完整的测试代码.

    <?php
    $responseCode = 0;
    $encoded='{
            "orderId":"12999763169054705758.1111111111111",

                    "purchaseState":0,
                    "purchaseToken":"tcmggamllmgqiabymvcgtfsj.AO-J1OwoOzoFd-G-....."

$data = json_decode($encoded,true);

$signature = "tKdvc42ujbYfLl+3sGdl7RAUPlNv.....";

$publicKey = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA2kMri6mE5+.....";

$key = "-----BEGIN PUBLIC KEY-----\n" . chunk_split($publicKey, 64, "\n") . "-----END PUBLIC KEY-----";
$key = openssl_get_publickey($key);
if (false === $key) {
        exit("error openssl_get_publickey");
}
var_dump($key);

$result = openssl_verify($data["purchaseToken"], base64_decode($signature), $key); // original // failed
//$result = openssl_verify($data, base64_decode($signature), $key); // failed …
