考虑一种WCF服务,其目的是在传输层需要客户端证书(IIS中的客户端证书设置为“必需”)。同样,消息层将有用户名验证。
现在我已经看到了这个问题:
WCF Client Certificate AND UserName Credentials forbidden
我可以在某种程度上理解那里发生了什么,并意识到WCF本身并不允许这两者。我在代码中执行了与上面引用的链接中的海报相同的步骤,并找到了相同的结果...消息级别的UserName凭据被传递(在我的情况下在SOAP标头中),但客户端证书(尽管是在VS调试中查看请求客户端时附加的,实际上并未由端点处理。
所以现在让我困惑的那部分。我决定稍微破解它。 我想知道为什么它的工作原理与我想要的一样......它超出了IIS客户端证书要求,UserName被传递给WCF服务并且一切正常。然而,WCF不允许我只使用WCF配置文件或代码(我能找到)。为什么?
// sets up a proxy client based on endpoint config
// basically just here to get the URL.
this.InitializeSubmitClient();
// these get used to create the HttpWebRequest
string url = this.submitClient.Endpoint.Address.ToString();
string action = "SubmitCDA";
// this deserializes an XML file which is the "shell" of SOAP document and inject username/password into SOAP Security node
XmlDocument soapEnvelopeXml = XMLHelper.CreateSoapDocument(this.txtSubmitCdaXmlFile.Text, this.txtAdAccount.Text, this.txtPassword.Text);
HttpWebRequest webRequest = XMLHelper.CreateWebRequest(url, action);
// saves the SOAP XML into the webRequest stream.
XMLHelper.InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest);
// attach the cert
if (this.chkSendClientCert.Checked)
{
X509Certificate myCert = X509Certificate.CreateFromCertFile(@"C:\temp\CDX-IHAT_DevClientCert.cer");
webRequest.ClientCertificates.Add(myCert);
}
else
{
webRequest.ClientCertificates.Clear();
}
// begin async call to web request.
IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);
更复杂的是,适用的WCF服务是BizTalk服务。
答案 0 :(得分:3)
以下是我最终如何做到这一点。
服务器配置:
<customBinding>
<binding name="CustomCDARequestEndpointBinding">
<textMessageEncoding messageVersion="Soap11" />
<security authenticationMode="UserNameOverTransport" />
<httpsTransport requireClientCertificate="true" />
</binding>
</customBinding>
客户端配置:
<system.ServiceModel>
<bindings>
<customBindings>
<binding name="CustomBinding_ITwoWayAsync">
<security defaultAlgorithmSuite="Default"
authenticationMode="UserNameOverTransport"
requireDerivedKeys="true"
includeTimestamp="true"
messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"
>
<localClientSettings detectReplays="false" />
<localServiceSettings detectReplays="false" />
</security>
<textMessageEncoding messageVersion="Soap11" />
<httpsTransport requireClientCertificate="true" />
</binding>
</customBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="ohBehave">
<clientCredentials useIdentityConfiguration="false">
<clientCertificate findValue="6D0DBF387484B25A16D0E3E53DBB178A366DA954" storeLocation="CurrentUser"
x509FindType="FindByThumbprint" />
</clientCredentials>
</behavior>
</endpointBehaviors>
</behaviors>
<client>
<endpoint address="https://myservice/CDASubmitService/CDASubmit.svc"
binding="customBinding" bindingConfiguration="SubmitDev" behaviorConfiguration="ohBehave"
contract="CDASubmitService.CDASubmit" name="SubmitDev" />
</client>
</system.serviceModel>
让它运作的关键是<httpsTransport requireClientCertificate="true" />
元素和<security authenticationMode="UserNameOverTransport"
元素/属性。
此配置允许我完全通过配置文件向WCF(BizTalk)服务提交消息,而不更改实际代码。它仍然允许我提交给VIA WebRequest,如上所示。
我必须赞扬这篇文章:
WCF Client Certificate AND UserName Credentials forbidden
以及这一个:
Translate non-BizTalk WCF config into BizTalk WCF-Custom endpoint
最终让我走上正轨。我总是回避WCF中的自定义绑定,因为我认为它有点矫枉过正,但它们真的没什么了不起的,只是提供比开箱即用更详细的配置的方法。
