PHP中的HMACSHA1等效

Question

我试图在HMACSHA1和C#中使用C#进行加密，但结果不同。C#部分完成。我想让part生成与C#部件相同的结果。

C#

     string key = "x94IudsnSUWCDSiSxRU5qDSRs88=";
     string text = "The quick brown fox jumps over the lazy dog";

     HMACSHA1 hmac = new HMACSHA1();
     hmac.Key = Convert.FromBase64String(key);
     byte[] hashedData = hmac.ComputeHash(Encoding.UTF8.GetBytes(text));
     string hash = Convert.ToBase64String(hashedData, Base64FormattingOptions.None);
     Console.WriteLine(WebUtility.UrlEncode(hash));

PHP

    $key = "x94IudsnSUWCDSiSxRU5qDSRs88=";
    $text = "The quick brown fox jumps over the lazy dog";

    $hash = base64_encode(hash_hmac('sha1', $text, $key,true));
    echo urlencode($hash);

结果: C#：uAG0CDzyuEq7zbQ5ZfpVrb1ZUcA%3D PHP：hx2c5SS6xI%2B8hQBoUqsWQT4KwP4%3D

在将密钥传递给hash_hmac函数之前，您可能必须先将php中的密钥传递给它。
