itfoxtec-identity-saml2 - ITfoxtec SAML 2.0 和 ASP.NET Web 表单 (ASPX) HttpRequest

Question

我正在尝试在 ASP.NET Web Forms (ASPX) 应用程序中实现 ITfoxtec SAML 2.0。

通常的 ASP.NET MVC 实现使用以下语句:

binding.ReadSamlResponse(Request.ToGenericHttpRequest(), saml2AuthnResponse);

但 MVC Request 在 Web 表单中不可用。

在 VB 中我尝试过如下代码

Dim request As New ITfoxtec.Identity.Saml2.Http.HttpRequest
request.Method = "GET"
request.Query = HttpContext.Current.Request.Form

binding.ReadSamlResponse(request, saml2AuthnResponse)

但这引发了异常:

Found invalid data while decoding.

at System.IO.Compression.InflaterZlib.ReadInflateOutput(Byte[] outputBuffer, Int32 offset, Int32 length, FlushCode flushCode, Int32& bytesRead)
at System.IO.Compression.InflaterZlib.Inflate(Byte[] bytes, Int32 offset, Int32 length)

at ITfoxtec.Identity.Saml2.Saml2Binding`1.ReadSamlResponse(HttpRequest request, Saml2Response saml2Response)
at [my code]

如何将 HttpContext.Current.Request 转换为 ITfoxtec.Identity.Saml2.Http.HttpRequest？

希望得到帮助，

谢谢安德斯。

我之所以出现这个问题，是因为我无意中将 binding 声明为 Saml2RedirectBinding 而不是 Saml2PostBinding。更正此问题后，ASP.NET MVC C# 语句:

binding.ReadSamlResponse(Request.ToGenericHttpRequest(), saml2AuthnResponse);

对于 VB 中的 ASP.NET Web 窗体，需要如下所示:

Dim request As New ITfoxtec.Identity.Saml2.Http.HttpRequest With
{
 .Method = HttpContext.Current.Request.HttpMethod,
 .Form = HttpContext.Current.Request.Form,
 .Query = New NameValueCollection,
 .QueryString = ""
}
binding.ReadSamlResponse(request, saml2AuthnResponse)

以防其他人需要此解决方案。
