itfoxtec-identity-saml2 SAML请求目的端口被剥离

Question

在发出SAML请求时，端口号(443)将从目标中剥离。我知道这是URI对象的默认行为。但是，SAML身份提供程序要求目的地包含端口号以进行验证。

怎样才能让SAML builder包含这个端口呢? 443是从https://sit-api.eat.xxxxxx.xxxx.xx:443/samlsso中去掉的(如下所示)

            Saml2Configuration samlconfig = GetSAMLConfig();

            var samlRequest = new Saml2AuthnRequest(samlconfig);
            samlRequest.AssertionConsumerServiceUrl = new Uri(_appConfiguration["Saml2:AssertionConsumerServiceUrl"]); 

            samlRequest.Destination = new Uri(_appConfiguration["Saml2:SingleSignOnDestination"]); // https://sit-api.eat.xxxxxx.xxxx.xx:443/samlsso

            samlRequest.NameIdPolicy = new NameIdPolicy()
            {
                AllowCreate = false,
                Format = "urn:oasis:names:tc:SAML:2.0:nameid-format:persistent",
                SPNameQualifier = _appConfiguration["Saml2:SPNameQualifier"]
            };

            samlRequest.Conditions = new Condition();
            samlRequest.Conditions.Items = new List<ITfoxtec.Identity.Saml2.Schemas.Conditions.ICondition>();
            samlRequest.Conditions.Items.Add(new ITfoxtec.Identity.Saml2.Schemas.Conditions.AudienceRestriction() { Audiences = new List<Audience>() { new Audience() { Uri = _appConfiguration["Saml2:AllowedAudienceUris"] } } });

            var bnd = binding.Bind(samlRequest);

如果您使用的是Saml2RedirectBinding，则可以在调用ToActionResult方法后更改目标URL。从而覆盖默认行为。

如下所示：

var action = binding.ToActionResult() as RedirectResult;
action.Url = action.Url.Replace("https://sit-api.eat.xxxxxx.xxxx.xx/samlsso", "https://sit-api.eat.xxxxxx.xxxx.xx:443/samlsso");
return action;
