My Map is:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with params
new { controller = "Home", action = "Index", id = "" } // Param defaults
);
If I use the URL http://localhost:5000/Home/About/100%2f200
there is no matching route.
I change the URL to http://localhost:5000/Home/About/100
then the route is matched again.
Is there any easy way to work with parameters that contain slashes? Other escaped values (space %20
) seem to work.
EDIT:
To encode Base64 works for me. It makes the URL ugly, but that's OK for now.
public class UrlEncoder
{
public string URLDecode(string decode)
{
if (decode == null) return null;
if (decode.StartsWith("="))
{
return FromBase64(decode.TrimStart('='));
}
else
{
return HttpUtility.UrlDecode( decode) ;
}
}
public string UrlEncode(string encode)
{
if (encode == null) return null;
string encoded = HttpUtility.PathEncode(encode);
if (encoded.Replace("%20", "") == encode.Replace(" ", ""))
{
return encoded;
}
else
{
return "=" + ToBase64(encode);
}
}
public string ToBase64(string encode)
{
Byte[] btByteArray = null;
UTF8Encoding encoding = new UTF8Encoding();
btByteArray = encoding.GetBytes(encode);
string sResult = System.Convert.ToBase64String(btByteArray, 0, btByteArray.Length);
sResult = sResult.Replace("+", "-").Replace("/", "_");
return sResult;
}
public string FromBase64(string decode)
{
decode = decode.Replace("-", "+").Replace("_", "/");
UTF8Encoding encoding = new UTF8Encoding();
return encoding.GetString(Convert.FromBase64String(decode));
}
}
EDIT1:
At the end it turned out that the best way was to save a nicely formated string for each item I need to select. Thats much better because now I only encode values and never decode them. All special characters become "-". A lot of my db-tables now have this additional column "URL". The data is pretty stable, thats why I can go this way. I can even check, if the data in "URL" is unique.
EDIT2:
Also watch out for space character. It looks ok on VS integrated webserver but is different on iis7 Properly url encode space character
