How to prevent default url decoding in ASP.net core

In my controller I have an HTTP get method that accepts a string

[HttpGet("{token}"]
public async Task<IActionResult> GetFoo(string token) 
{
     //Some actine
     return Ok(object);
 }

If I send the below-encoded token test%2Atest, ASP .NET will decode this token to test*test by default. But if I send test%2Ftest, it does not decode the %2F to /.

I can understand why ASP.NET doesn't do that as it breaks the routes.

Is there a way to disable this default behavior so I can de the decoding in my controller?

Solution

  • I could not find a way to disable default URL decoding in ASP.net core.

    As Tiny Wang suggested above, I changed the application to send the token in the header and that fixed the problem.
