22-Consent 确认逻辑实现

1-定义一个从前台传到后台的viewModel

namespace MvcCookieAuthSample.Models
{
    public class InputConsentViewModel
    {
        public string Button { get; set; }

        public IEnumerable<string> ScopesConsented { get; set; }

        public bool RemeberConsent { get; set; }

        public string ReturnUrl { get; set; }

    }
}

2-确定逻辑实现

        [HttpPost]
        public async Task<IActionResult> Index(InputConsentViewModel viewModel)
        {
            ConsentResponse consentResponse = null;
            if (viewModel.Button == "no")
            {
                consentResponse = ConsentResponse.Denied;
            }
            else if (viewModel.Button == "yes")
            {
                if(viewModel.ScopesConsented!=null && viewModel.ScopesConsented.Any())
                {
                    consentResponse = new ConsentResponse {
                         ScopesConsented=viewModel.ScopesConsented,
                         RememberConsent = viewModel.RemeberConsent
                    };
                  
                }
            }
            if (consentResponse != null)
            {
                var request = await _identityServerInteractionService.GetAuthorizationContextAsync(viewModel.ReturnUrl);
                await _identityServerInteractionService.GrantConsentAsync(request, consentResponse);
                return  Redirect(viewModel.ReturnUrl);
            }

            return View();
        }
