Question

ASP.NET /Mono MVC4购物车应用程序用户产品代码作为awstats分析的URL名称，如：

http://myshop.com/Store/Details/PRODUCT1

使用默认路由和控制器

    public class StoreController : MyApp.ControllerBase
    {

        public ActionResult Details(string id)
        {
  ....

PRODUCT1是产品代码。如果产品代码包含目录名中的/和其他不允许的字符，则Web服务器会抛出错误。

产品代码应该是人类可读的，因为分析显示了网址。如何将产品代码编码为目录名称并在控制器中解码？编码后，产品代码应保持唯一。

ASP.NET中是否有一些内置函数或一些实现此功能的源代码？

使用jquery，jquery ui，razor视图引擎。

更新

我通过创建Razor助手

在评论中尝试了推荐

@helper Details(string toode)
{
    @Url.Action("Details", new { id = HttpUtility.UrlEncode(toode) });
}

然后使用

<a href="@Details(someproduct)">

这会导致错误：

从客户端（％）检测到潜在危险的Request.Path值。   GET / Store / Details / S％c3％9c％c3％9cTAJA HTTP / 1.0
     url路径中不允许
％chareter。   所以UrlEncode无法使用。如何编码/解码？

您可以使用加密和解密算法（加密）来实现这样的目标......

 public class CryptoEngine
    {

        private static CryptoEngine _instance;
        private CryptoEngine() { }
        public static CryptoEngine Instance
        {
            get
            {
                if (_instance == null)
                    _instance = new CryptoEngine();

                return _instance;
            }
        }

        static readonly string PasswordHash = "@dM!nCo$";
        static readonly string SaltKey = "AdMinCos";
        static readonly string VIKey = "Polar!s@dM!nCoN$";

        public string Encrypt(string plainText)
        {
            byte[] plainTextBytes = Encoding.UTF8.GetBytes(plainText);

            byte[] keyBytes = new Rfc2898DeriveBytes(PasswordHash, Encoding.ASCII.GetBytes(SaltKey)).GetBytes(256 / 8);
            var symmetricKey = new RijndaelManaged() { Mode = CipherMode.CBC, Padding = PaddingMode.Zeros };
            var encryptor = symmetricKey.CreateEncryptor(keyBytes, Encoding.ASCII.GetBytes(VIKey));

            byte[] cipherTextBytes;

            using (var memoryStream = new MemoryStream())
            {
                using (var cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write))
                {
                    cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
                    cryptoStream.FlushFinalBlock();
                    cipherTextBytes = memoryStream.ToArray();
                    cryptoStream.Close();
                }
                memoryStream.Close();
            }
            return Convert.ToBase64String(cipherTextBytes);
        }

        public string Decrypt(string encryptedText)
        {
            encryptedText = encryptedText.Trim();
            if (encryptedText.Contains(" "))
            {
                encryptedText = encryptedText.Replace(" ", "+");
            }

            byte[] cipherTextBytes = Convert.FromBase64String(encryptedText);
            byte[] keyBytes = new Rfc2898DeriveBytes(PasswordHash, Encoding.ASCII.GetBytes(SaltKey)).GetBytes(256 / 8);
            var symmetricKey = new RijndaelManaged() { Mode = CipherMode.CBC, Padding = PaddingMode.None };

            var decryptor = symmetricKey.CreateDecryptor(keyBytes, Encoding.ASCII.GetBytes(VIKey));
            var memoryStream = new MemoryStream(cipherTextBytes);
            var cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
            byte[] plainTextBytes = new byte[cipherTextBytes.Length];

            int decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length);
            memoryStream.Close();
            cryptoStream.Close();
            return Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount).TrimEnd("\0".ToCharArray());
        }
    }

并像这样使用它......

"/Store/Details?id="+CryptoEngine.Instance.Encrypt(toode))

在你的行动中，你可以像这样解密它......

public ActionResult Details(string id)
{
   string _id = CryptoEngine.Instance.Decrypt(id);
   .......

您可以设置PasswordHash，SaltKey和VIKey 我想这就是你想要的。
