Question

我有一个用于保存高分表的sql数据库。当我发送数据时，我有这个PHP代码：

    <?php 
        $db = mysql_connect('mysql', 'myuser', 'mypass') or die('Could not connect: ' . mysql_error()); 
        mysql_select_db('my_db') or die('Could not select database');

        // Strings must be escaped to prevent SQL injection attack. 
        $name = mysql_real_escape_string($_GET['name'], $db); 
        $score = mysql_real_escape_string($_GET['score'], $db); 
        $hash = $_GET['hash']; 

        $secretKey="mySecretKey"; 

        $real_hash = md5($name . $score . $secretKey); 
        if($real_hash == $hash) { 
            // Send variables for the MySQL database class. 
            $query = "insert into scores values (NULL, '$name', '$score');"; 
            $result = mysql_query($query) or die('Query failed: ' . mysql_error()); 
        } 
?>

现在，我在c＃中有两段代码...一台发送数据，调用函数和函数本身...

发送数据：

IEnumerator PostScores(string name, int score)
{
    string hash = Md5Functions.Md5Sum(name + score + secretKey);

    string post_url = addScoreURL + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;

    WWW hs_post = new WWW(post_url);
    yield return hs_post; 

    if (hs_post.error != null)
    {
        print("There was an error posting the high score: " + hs_post.error);
    }
}

当一切正常时，这就是我的功能：

using UnityEngine;
  using System.Collections;    

  Public Static Md5Functions {
        public  static string Md5Sum(string strToEncrypt)
{
    System.Text.UTF8Encoding ue = new System.Text.UTF8Encoding();
    byte[] bytes = ue.GetBytes(strToEncrypt);

    // encrypt bytes
    System.Security.Cryptography.MD5CryptoServiceProvider md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
    byte[] hashBytes = md5.ComputeHash(bytes);

    // Convert the encrypted bytes back to a string (base 16)
    string hashString = "";

    for (int i = 0; i < hashBytes.Length; i++)
    {
        hashString += System.Convert.ToString(hashBytes[i], 16).PadLeft(2, '0');
    }

    return hashString.PadLeft(32, '0');
}

现在，由于我必须将整个解决方案导入Visual Studio而且它不允许MD5CryptoServiceProvider，我已经搜索过并且我更改了这个Md5Function：

using UnityEngine;
using System.Collections;

#if UNITY_METRO
using Windows.Security.Cryptography;
using Windows.Security.Cryptography.Core;
using Windows.Storage.Streams;
#else
using System.Text;
using System.Security.Cryptography;
#endif

public static class Md5Functions
{
    static string md5val;

    static void Start()
    {
        md5val = Md5Sum("Hello World!");
        Debug.Log(md5val);
    }

    static void OnGUI()
    {
        GUILayout.Label(md5val);
    }

    public static string Md5Sum(string strToEncrypt)
    {
#if UNITY_METRO

        // Convert the message string to binary data.
        IBuffer buffUtf8Msg = CryptographicBuffer.ConvertStringToBinary(strToEncrypt, BinaryStringEncoding.Utf8);


        // Create a HashAlgorithmProvider object.
        HashAlgorithmProvider objAlgProv = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Md5);

        // Demonstrate how to retrieve the name of the hashing algorithm.
        string strAlgNameUsed = objAlgProv.AlgorithmName;

        // Hash the message.
        IBuffer buffHash = objAlgProv.HashData(buffUtf8Msg);

        // Verify that the hash length equals the length specified for the algorithm.
        if (buffHash.Length != objAlgProv.HashLength)
            return null;

        // Convert the hash to a string (for display).
        string strHashBase64 = CryptographicBuffer.EncodeToBase64String(buffHash);

        // Return the encoded string
        return strHashBase64.PadLeft(32, '0');
#else
        UTF8Encoding ue = new UTF8Encoding();
        byte[] bytes = ue.GetBytes(strToEncrypt);

        // encrypt bytes
        MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
        byte[] hashBytes = md5.ComputeHash(bytes);

        // Convert the encrypted bytes back to a string (base 16)
        string hashString = "";

        for (int i = 0; i < hashBytes.Length; i++)
        {
            hashString += System.Convert.ToString(hashBytes[i], 16).PadLeft(2, '0');
        }

        return hashString.PadLeft(32, '0');
#endif
    }
}

当然，现在，它不起作用，因为php代码是为第一个Md5Function制作的......

愿你们中的任何人帮我解决这个问题，所以我可以让它再次运行，请使用最后一个Md5Function吗？

将数据从c＃发送到php（高分表）
