% not accepted as part of the string parameter in Web API

I want to send a string parameter to my Web API Endpoint. The string is: TCmBqAKPGVMlTQ2Exw/viQ==, so as we see it contains a /. I am encoding this string and now the value is TCmBqAKPGVMlTQ2Exw%2FviQ%3D%3D, but I still can not reach the API Endpoint.

This is the error I am getting:

headers: HttpHeaders {normalizedNames: Map(0), lazyUpdate: null, lazyInit: ƒ}
message: "Http failure response for http://localhost:31676/api/TokenTest/check-token-validation/96/TCmBqAKPGVMlTQ2Exw%2FviQ%3D%3D:

404 Not Found" name: "HttpErrorResponse" ok: false status: 404 statusText: "Not Found" url: "http://localhost:31676/api/TokenTest/check-token-validation/96/TCmBqAKPGVMlTQ2Exw%2FviQ%3D%3D" proto: HttpResponseBase

If you are using Attribute routing , you can try below code sample :

[Route("api/[controller]")]
[ApiController]
public class TokenTestController : ControllerBase
{
    [HttpGet]
    [Route("check-token-validation/{id}")]
    public ActionResult<IEnumerable<string>> CheckTokenValidation(int id, string para)
    {
        return new string[] { "value1", "value2" };
    }
}

If the request is https://localhost:xxxx/api/TokenTest/check-token-validation/96?para=TCmBqAKPGVMlTQ2Exw/viQ== you will get the correct result :

But url encode is always suggested .

You can use function encodeURIComponent(yourstring) to encode special character in URL.

And change Url to http://localhost:31676/api/TokenTest/check-token-validation/96?parameterName=TCmBqAKPGVMlTQ2Exw%2FviQ%3D%3D
