WCF客户端传递用户名令牌并将mustUnderstand设置为true

Question

我的任务是创建一个将由外部客户端使用的WCF服务.客户端使用WSSE安全性,具体来说,它们通过SOAP头传递用户名令牌.

WCF服务托管在启用了SSL的IIS服务器上.

在这一点上,我有一个半工作原型.我现在要处理的问题是SOAP标头的mustUnderstand属性设置为1,这会导致进程失败.

我想要一些关于如何处理用户名令牌的建议(或者更好的是,代码示例微笑),以便在mustUnderstand属性为true时返回正确的响应.

以下是失败的SOAP请求示例:

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
       <soapenv:Header>
          <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
             <wsse:UsernameToken>
                <wsse:Username>TestUser</wsse:Username>
                <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">TestPWD</wsse:Password>
                <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">NzU3MjFhN2YtYTlmYS00ZWZjLTkxNjktY2ExZjlkZDEwNzE5</wsse:Nonce>
                <wsu:Created xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">2011-10-26T03:04:39Z</wsu:Created>
             </wsse:UsernameToken>
          </wsse:Security>
       </soapenv:Header>
       <soapenv:Body>
          <tem:Getstuff>
             <tem:Arg1>Arg1</tem:Arg1>
             <tem:Arg2>Arg2</tem:Arg2>
          </tem:Getstuff>
       </soapenv:Body>
    </soapenv:Envelope>

如果soapenv:mustUnderstand ="1"更改为soapenv:mustUnderstand ="0",则该过程有效.

PS:这是客户发送的修订样本请求:

    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

         <Arg2>Arg2</Arg2>
        </Getstuff>
      </s:Body>
    </s:Envelope>

我收到以下对上述请求的回复:

    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
       <s:Body>
          <s:Fault>
             <faultcode>s:MustUnderstand</faultcode>
             <faultstring xml:lang="en-US">The header 'Security' from the namespace 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd' was not understood by the recipient of this message, causing the message to not be processed.  This error typically indicates that the sender of this message has enabled a communication protocol that the receiver cannot process.  Please ensure that the configuration of the client's binding is consistent with the service's binding.</faultstring>
          </s:Fault>
       </s:Body>
    </s:Envelope>

这是绑定:

<bindings>
  <basicHttpBinding>
    <binding name="TransportBind" maxBufferSize="2147483647" maxBufferPoolSize="2147483647"
      maxReceivedMessageSize="2147483647">

        <transport clientCredentialType="None" />
      </security>

Answer 1

+1 @JohnSaunders 因为他很可能在这里咆哮正确的树。

你的客户端是.NET/WCF吗？如果没有，它可能没有实现 WS-Security，或者至少没有以 WCF 希望的方式实现。

如果客户端是.NET，则这只是客户端的绑定不匹配。

MustUnderstand 标志表示必须确认和处理 WS-Security 标头。非 WS-Security 客户端，无论是因为它不支持 WS-Security 还是未配置为，都会忽略该标头，无论如何尝试使用该消息，并且服务器将进行平踢。

您的另一个选择是关闭服务器上的否认。它将停止发送 WS-Security 标头。当然，这样你就不会遭到拒绝。
