我需要将 SAML 身份验证添加到我的 Web 应用程序(WebAPI 后端/角度前端),并将 Azure AD 作为我的身份提供者。

我计划使用 Sustainsys.Saml2 库,但我不确定如何正确使用该库提供的方法。

我已经将我的 Web 应用程序添加为 Azure AD 上的企业应用程序,并执行了必要的 SSO SAML 配置。

我在 web.config 中配置了sustainsys,如下所示:

<sustainsys.saml2 entityId="https://myWebApp/api/saml/login" returnUrl="https://myWebApp/">
  <identityProviders>
    <add 
      entityId="https://sts.windows.net/36tg486z-9l1f/" 
      signOnUrl="https://login.microsoftonline.com/36tg486z-9l1f/saml2"
      metadataLocation="https://login.microsoftonline.com/36tg486z-9l1f/federationmetadata/2007-06/federationmetadata.xml?appid=82fc2g56-2as2"
      allowUnsolicitedAuthnResponse="true"
      loadMetadata="true"
      binding="HttpPost"
    >
    </add>
  </identityProviders>
    <serviceCertificates>
        <add fileName="~/App_Data/Sustainsys.Saml2.Tests.pfx" />
  </serviceCertificates>
</sustainsys.saml2>

我的想法是编写两个 API:

1 - 执行登录到 Azure AD 的 API:

[HttpGet]
[Route("api/saml/signIn")]
[ResponseType(typeof(void))]
public HttpResponseMessage SignIn()
{
  var context = new HttpContextWrapper(HttpContext.Current);
  HttpRequestBase request = context.Request;

  var opt = Sustainsys.Saml2.Configuration.Options.FromConfiguration;
  var result = CommandFactory.GetCommand(CommandFactory.SignInCommandName).Run(request.ToHttpRequestData(), opt);
  var response = Request.CreateResponse(result.HttpStatusCode);

  if (!string.IsNullOrEmpty(result.SetCookieName))
  {
    var protectedData = HttpRequestData.ConvertBinaryData(MachineKey.Protect(result.GetSerializedRequestState(),HttpRequestBaseExtensions.ProtectionPurpose));

    var cookie = new CookieHeaderValue(result.SetCookieName, protectedData) { HttpOnly = true };
    var cookies = new List<CookieHeaderValue>() { cookie };
    response.Headers.AddCookies(cookies);
  }

  response.Headers.Location = result.Location;
  return response;
}

2 - 接收来自 Azure AD 的响应并读取 SAML 令牌内的声明的 API:

[HttpPost]
[Route("api/saml/acs")]
[ResponseType(typeof(result))]
public HttpResponseMessage Acs()
{
  var context = new HttpContextWrapper(HttpContext.Current);
  HttpRequestBase request = context.Request;

  var opt = Sustainsys.Saml2.Configuration.Options.FromConfiguration;
  var result = CommandFactory.GetCommand(CommandFactory.AcsCommandName).Run(request.ToHttpRequestData(), opt);

  // ... read claims ...

  // ... build [LoginResult] with claims ...
  var response = Request.CreateResponse(result.HttpStatusCode, [LoginResult]);

  response.Headers.Location = new Uri(result.Location.AbsoluteUri);

  return response;
}

这是使用 SustainSys 添加 SAML 身份验证的正确方法吗?

这是使用 SustainSys 存根 Idp 的 WebApi + Angular Spa 的工作示例。它也可以与 Azure AD 配置一起使用。
