我需要调用一些需要WS-Security的第三个Web服务.我创建了一个具有以下配置的WCF端点：
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="TestBinding">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="Certificate" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="TestBehavior">
<callbackDebug includeExceptionDetailInFaults="true" />
<clientCredentials>
<clientCertificate findValue="Acme" storeLocation="CurrentUser" storeName="My" x509FindType="FindBySubjectName" />
<serviceCertificate>
<authentication certificateValidationMode="PeerOrChainTrust" />
</serviceCertificate>
</clientCredentials>
</behavior>
</endpointBehaviors>
</behaviors>
<client>
<endpoint address="https://acme.com/webservices" binding="wsHttpBinding" bindingConfiguration="TestBinding" behaviorConfiguration="TestBehavior" contract="AcmeContract" name="AcmeEndpoint"></endpoint>
</client>
</system.serviceModel>
问题是第三方服务器抛出以下异常：
Received protocol
‘_http://schemas.xmlsoap.org/wsdl/soap12/’,
required protocol
‘_http://schemas.xmlsoap.org/wsdl/soap/’.
我明白,使用wsHttpBinding将导致WCF发送SOAP 1.2请求,而使用basicHttpBinding会导致SOAP 1.1请求.由于WS-Security部分是必需的,据了解,我必须使用wsHttpBinding.我的问题是如何强制SOAP 1.1请求？我有什么选择？
解决方法
为了使用WS-Addressing(wsHttpBinding),但是使用SOAP 1.1(默认为SOAP 1.2),您需要定义一个自定义的WCF绑定(例如在config中),并使用它：
<bindings>
<customBinding>
<binding name="WsHttpSoap11" >
<textMessageEncoding messageVersion="Soap11WSAddressing10" />
<httpTransport/>
</binding>
</customBinding>
</bindings>
然后在您的端点定义中,使用：
<endpoint name="WsSoap11"
address="....."
binding="customBinding"
bindingConfiguration="wsHttpSoap11"
contract="....." />
当然,您可以使用附加属性扩展上面定义的绑定,例如< ReliableMessaging的>或其他.
有关WCF绑定的更为非常详细,非常有用的信息以及如何在配置中“编写”自己的自定义绑定,请阅读Aaron Skonnard发表的这篇优秀的MSDN文章Service Station: WCF Bindings In Depth.
