When i use <TargetFramework>net462</TargetFramework>
for my Okta SAML implementation this throw a Invalid URL when it this new Saml2AuthnRequest(config);
当我将
<TargetFramework>net462</TargetFramework>
用于我的 Okta SAML 实现时,当它使用这个new Saml2AuthnRequest(config);
but on my first try using this code on netcoreapp3.1` this worked perfectly fine.但在我第一次尝试在 netcoreapp3.1 上使用此代码时,它工作得非常好。 Please let me know if i miss something thank you.
如果我错过了什么,请告诉我谢谢。
[HttpGet, AllowAnonymous]
public IActionResult Index(string returnUrl = null)
{
try
{
var config = GetSAMLConfig();
var binding = new Saml2RedirectBinding();
binding.SetRelayStateQuery(new Dictionary<string, string> { { relayStateReturnUrl, returnUrl ?? Url.Content("~/") } });
var request = new Saml2AuthnRequest(config);
return binding.Bind(request).ToActionResult();
}
catch (Exception e)
{
Console.WriteLine(e);
throw;
}
}
private Saml2Configuration GetSAMLConfig()
{
var config = new Saml2Configuration();
config.AllowedAudienceUris.Add("Okta_SAML_Example");
config.CertificateValidationMode = X509CertificateValidationMode.ChainTrust;
config.RevocationMode = X509RevocationMode.NoCheck;
var entityDescriptor = new EntityDescriptor();
entityDescriptor.ReadIdPSsoDescriptorFromUrl(new Uri("https://---------.okta.com/app/exk2b0b7dibno7rOB5d6/sso/saml/metadata"));
if (entityDescriptor.IdPSsoDescriptor != null)

config.SingleSignOnDestination = entityDescriptor.IdPSsoDescriptor.SingleSignOnServices.First().Location;
config.SignatureValidationCertificates.AddRange(entityDescriptor.IdPSsoDescriptor.SigningCertificates);
}
else
{
throw new Exception("IdPSsoDescriptor not loaded from metadata.");
}
return config;
}
Actual exception实际异常

The code looks correct.代码看起来正确。
Maybe it is a TLS version issue.可能是 TLS 版本问题。
An alternative solution is to download the metadata in your code and add the metadata string to the ITfoxtec Identity SAML 2.0 library:另一种解决方案是在您的代码中下载元数据并将元数据字符串添加到ITfoxtec Identity SAML 2.0库:
var idPMetadataXml = "... downloaded metadata ...";
var entityDescriptor = new EntityDescriptor();
entityDescriptorReadIdPSsoDescriptor(idPMetadataXml);
...
Updated:更新:
The error seams to be in relation to Audience Restriction:错误接缝与观众限制有关:
config.AllowedAudienceUris.Add("Okta_SAML_Example");
The audience have to be a URI in a .NET Framework application.受众必须是 .NET 框架应用程序中的 URI。 Plain text strings are only supported in .NET Core and .NET 5.0.
纯文本字符串仅在 .NET Core 和 .NET 5.0 中受支持。
.NET Framework sample: https://github.com/ITfoxtec/ITfoxtec.Identity.Saml2/tree/master/test/TestWebApp .NET 框架示例: https://github.com/ITfoxtec/ITfoxtec.Identity.Saml2/tree/master/test/TestWebApp
I had the same issue and it was caused by "GetAudienceRestriction() method".我有同样的问题,它是由“GetAudienceRestriction() 方法”引起的。 Changing issuer name from "application-name" to "https://application-name" helped.
将发行者名称从“application-name”更改为“https://application-name”有帮助。 Don't forget to change your name on your Identity Provider side (Okta, Ping Identity etc.) consistently.
不要忘记在身份提供者端(Okta、Ping Identity 等)始终更改您的名称。 Now exception is not thrown anymore.
现在不再抛出异常。
