如何使用 Windows 凭据在 silveright 应用程序中从 ADFS 获取 SAML 令牌

Question

我正在尝试通过 silverlight 应用程序实现主动联合。 我想从我的 silverlight 应用程序中向 ADFS 请求 SAML 令牌。 我无法在 silverlight 应用程序中使用 WSTrustChannel，因为它不允许添加 System.IdentityModel 或 Microsoft.IdentityModel。 请帮忙。

//This code will get you the SAML Token for SAP Odata Services in C# for Desktop or Web
protected HttpClient Client
{
    get
    {
        if (client == null)
        {
            handler = new HttpClientHandler();

            handler.Credentials = new NetworkCredential(username, password);
            handler.AllowAutoRedirect = false;
            handler.CookieContainer = cookies;
            handler.UseCookies = true;
            client = new HttpClient(handler);
            client.MaxResponseContentBufferSize = 9999999;
            client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
            client.DefaultRequestHeaders.Add("Connection", "Keep-Alive");
            client.DefaultRequestHeaders.ExpectContinue = false;
        }
        return client;
    }
}
public String GetSAML()
{    
    if (client != null)
    {
        client = null;
    }
    String text = "";
    String SAMLTokenBase64String="";
    String urlRelayParty = "Your_Relay_party_identifier";
    string url = String.Format("{0}?loginToRp={1}", "https://***yourdomainforstsoradfs*****.com/adfs/ls/IdpInitiatedSignOn.aspx", HttpUtility.UrlEncode(urlRelayParty));
    do
    {
        result = Client.GetAsync(url).GetAwaiter().GetResult();
        text = result.Content.ReadAsStringAsync().GetAwaiter().GetResult();
        IEnumerable<string> values;
        if (result.Headers.TryGetValues("location", out values))
        {
            foreach (string s in values)
            {
                if (s.StartsWith("/"))
                {
                    url = url.Substring(0, url.IndexOf("/adfs/ls")) + s;
                }
                else
                    url = s;

    Regex reg = new Regex("SAMLResponse\\W+value\\=\\\"([^\\\"]+)\\\"");
    MatchCollection matches = reg.Matches(text);
    foreach (Match m in matches)

        SAMLTokenBase64String = m.Groups[1].Value;

        return SAMLTokenBase64String;
    }
    

    SB("STS Login Failed for " + urlRelayParty);
    return "";
