我需要转换为PHP的C#方法。我尝试了几件事,但我仍然得到了不同的结果。不幸的是我无法改变C#应用程序的任何内容。它必须是现实的。也许你们中的一个可以帮忙吗?
C#:
static public void Main ()
{
string StringToSign = "test";
string Key = "123456";
//Calculate Signature
string Signature = CalculateSignature(StringToSign, Key);
Console.WriteLine ("StringToSign: " + StringToSign);
Console.WriteLine ("Key: " + Key);
Console.WriteLine ("Signature Caculated: " + Signature + "\r\n");
}
static private string CalculateSignature(String StringToSign, String Key)
{
Encoding enc = Encoding.GetEncoding(65001);
byte[] KeyHex = StringHexValuesToByteArray(Key);
byte[] StringToSign_byte = enc.GetBytes(StringToSign);
//Check Signature
HMACSHA256 hmac = new HMACSHA256(KeyHex);
byte[] hashValue = hmac.ComputeHash(StringToSign_byte);
return BitConverter.ToString(hashValue).Replace("-", "");
}
static public byte[] StringHexValuesToByteArray(string str)
{
if (str.Length % 2 != 0)
return null;
string s = string.Empty;
byte[] ret = new byte[str.Length / 2];
for (int run = 0; run < str.Length / 2; run++)
{
s = str.Substring(run * 2, 2);
ret[run] = Convert.ToByte(s, 16);
}
return ret;
}
PHP:
public function send() {
$stringToSign = 'test';
$key = '123456';
//Calculate Signature
$signature = $this->calculateSignature($stringToSign, $key);
print_r("StringToSign: " . $stringToSign . PHP_EOL);
print_r("Key: " . $key . PHP_EOL);
print_r("Signature Caculated: " . $signature . PHP_EOL);
}
private function calculateSignature($stringToSign, $key) {
// check signature
$hash = strtoupper(hash_hmac('sha256', $stringToSign, $key, false));
return $hash;
}
为了更好地理解,以下是上面代码块的输出:
C#
StringToSign:test
密钥:123456
Signature Caculated: DA3617974490FB780F04F06287BF93B0F24A7F15970471146428B943FFDC7850
PHP
StringToSign:test
GroupKey:123456
签名计算:9D2BB116E1DF997FFE8A5139FC1D187F976C19579A138414A112BC2E39020EBA
答案 0 :(得分:1)
如果您想修改PHP以使其等同于C#
更改
$hash = strtoupper(hash_hmac('sha256', $stringToSign, $key, false));
到
$hash = strtoupper(hash_hmac('sha256', $stringToSign, hex2bin($key), false));
请务必检查代码是否适用于{_ 1}}等非ASCII字符。
如果您想修改C#代码以使其等同于PHP
你使一切变得复杂:

没有任何十六进制。而不是使用static private string CalculateSignature(String stringToSign, String key)
{
byte[] key_byte = Encoding.UTF8.GetBytes(key);
byte[] stringToSign_byte = Encoding.UTF8.GetBytes(stringToSign);
//Check Signature
HMACSHA256 hmac = new HMACSHA256(key_byte);
byte[] hashValue = hmac.ComputeHash(stringToSign_byte);
return BitConverter.ToString(hashValue).Replace("-", "");
}
通常最好使用Encoding.GetEncoding(65001)
,因为每个人都更清楚。
请注意,编码可能存在问题。尝试计算Encoding.UTF8
之类的hmac,看看PHP正在使用哪种编码。
