活动客户端-使用idp令牌从资源合作伙伴adfs获取令牌

我正在尝试用以下场景编写控制台应用程序:客户端首先从身份提供者请求令牌，然后使用该令牌从资源STS请求新的令牌使用以下链接:http://leastprivilege.com/2010/10/28/wif-adfs-2-and-wcfpart-6-chaining-multiple-token-services/

我设法从Idp获得令牌，但没有设法从资源STS获得令牌。

这是我的代码:

    string RPRealm = "https://service.contoso.com/";
    string RSTSRealm = "http://fsweb.contoso.com/adfs/services/trust";
    string IdPstsEndpoint = "https://IdpAdfs.domain.com/adfs/services/trust/13/kerberosmixed";
    string RSTSEndpoint = "https://fsweb.contoso.com/adfs/services/trust/13/IssuedTokenMixedSymmetricBasic256";
    private static SecurityToken GetIdPToken(string rstsRealm, string IdPstsEndpoint)
    {
        using (var factory = new WSTrustChannelFactory(
                new KerberosWSTrustBinding(SecurityMode.TransportWithMessageCredential),
                new EndpointAddress(new Uri(IdPstsEndpoint))))
        {
            WSTrustChannel channel = null;
            factory.TrustVersion = TrustVersion.WSTrust13;
            try
            {
                var rst = new RequestSecurityToken
                {
                    RequestType = WSTrust13Constants.RequestTypes.Issue,
                    AppliesTo = new EndpointAddress(rstsRealm),
                    KeyType = WSTrust13Constants.KeyTypes.Bearer,
                };
                channel = (WSTrustChannel)factory.CreateChannel();
                RequestSecurityTokenResponse rstr;
                SecurityToken token = channel.Issue(rst, out rstr);
                return token;
            }
            finally
            {
                if (channel != null)
                {
                    channel.Abort();
                }
                factory.Abort();
            }
        }
    }

private static SecurityToken GetRSTSToken(SecurityToken IdPToken, string RSTSEndpoint, string RPRealm)
{
   var binding = new WS2007FederationHttpBinding();
   binding.Security.Message.IssuedKeyType = SecurityKeyType.BearerKey;
   binding.Security.Message.EstablishSecurityContext = false;
   binding.Security.Mode = WSFederationHttpSecurityMode.TransportWithMessageCredential;
    using (var factory = new WSTrustChannelFactory(
           binding,
            new EndpointAddress(new Uri(RSTSEndpoint))))
    {
        var rst = new RequestSecurityToken
        {
            RequestType = WSTrust13Constants.RequestTypes.Issue,
            AppliesTo = new EndpointAddress(RPRealm),
            KeyType = WSTrust13Constants.KeyTypes.Bearer,
        };
        factory.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
        factory.TrustVersion = TrustVersion.WSTrust13;
        factory.Credentials.SupportInteractive = false;
        factory.ConfigureChannelFactory();

        var channel = factory.CreateChannelWithIssuedToken(IdPToken);
        RequestSecurityTokenResponse rstr;
        SecurityToken token = channel.Issue(rst, out rstr);
        return token;
    }
}

我得到这个错误:响应消息的内容类型text/html与绑定的内容类型不匹配(application/soap+xml;charset = utf - 8)我的代码有什么问题?提前感谢
