如何在Asp.Net Core2.2中将[FromHeader]属性与自定义模型绑定一起使用

public class RequestHeadersModel
{
    public string CustomHeader { get; set; }
    public int CustomIntHeader { get; set; }
}

[ApiController]
[Route("api/[controller]")]
public class SampleController : ControllerBase
{
    [HttpGet]
    public IActionResult Get([FromHeader] RequestHeadersModel headers)
    {
        if (ModelState.IsValid)
        {
            return Ok(new { message = "Headers bound successfully", headers });
        }
        else
        {
            return BadRequest(ModelState);
        }
    }
}

public class RequestHeadersModelBinder : IModelBinder
{
    public Task BindModelAsync(ModelBindingContext bindingContext)
    {
        if (bindingContext == null)
            throw new ArgumentNullException(nameof(bindingContext));

        var model = new RequestHeadersModel
        {
            CustomHeader = bindingContext.HttpContext.Request.Headers["Custom-Header"].ToString(),
            CustomIntHeader = int.Parse(bindingContext.HttpContext.Request.Headers["Custom-Int-Header"])
        };

        bindingContext.Model = model;
        return Task.CompletedTask;
    }
}

[ModelBinder(BinderType = typeof(RequestHeadersModelBinder))]
public class RequestHeadersModel
{
    // ...
}
