FromHeader Asp.NET Core binding to default value

asp.net, asp.net-core-webapi, binding, c#, http-headers

Solution

form headers accept `string` not `int` so your code should be

[Route("test")]
public class TestController
{
        [Route("mult")]
        [HttpGet]
        public int Multiply([FromHeader]string x, [FromHeader]string y)
        {

            return Int32.Parse(x) * Int32.Parse(y);
        }
}

you have to get values of `x` and `y` in `string` and convert it to `int`

Problem

I'm testing Asp.Net core WebApi with the following basic controller: ``` [Route("test")] public class TestController { [Route("mult")] [HttpGet] public int Multiply(int x, int y) { return x * y; } } ``` Then, in Fiddler, I send the following request: And, for some reason, the response is 0. Both `x` and `y` are binded to the default integer value when entering the method. I also tried: ``` [Route("test")] public class TestController { [Route("mult")] [HttpGet] public int Multiply([FromHeader]int x, [FromHeader]int y) { return x * y; } } ``` But the result is the same. What am I doing wrong?
