WCF FaultCode MustUnderstand = 1 .net 4.0

Question

如何更改我的wcf服务才能接受mustunderstand = 1？在这种情况下，我必须更改服务才能接受来自客户端的请求。客户端在标头中发送mustunderstand = 1。

该服务配置为使用basichttpBinding

 <security mode="TransportWithMessageCredential">
            <message clientCredentialType="UserName"/>
            <transport clientCredentialType="None"></transport>
          </security>

使用soap UI我将以下用户名标记插入标题

 <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
         <wsse:UsernameToken wsu:Id="UsernameToken-2684C13EA73A35131015516775308851">
            <wsse:Username>username</wsse:Username>
            <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</wsse:Password>

         </wsse:UsernameToken>
      </wsse:Security>

当我在wcf服务请求中插入此令牌时，我可以在soap UI上重现该问题。这是错误

<FaultMsgRec>
  <ErrCode>100</ErrCode>
  <ErrCat>Error</ErrCat>
  <ErrDesc>An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.--&gt; 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. </ErrDesc>
</FaultMsgRec>

由于我可以控制wcf服务，因此可以在服务行为中添加ValidateMustUnderstand = false。就像链接https://docs.microsoft.com/en-us/dotnet/api/system.servicemodel.description.mustunderstandbehavior.validatemustunderstand?view=netframework-4.7.2中解释的那样

一旦我将其添加到服务行为，错误就会消失。但我不想关闭标题上的验证，特别是如果它的用户名，密码。我应该怎么做才能允许mustunderstand = 1？我错过了默认情况下服务无法自动处理mustunderstand = 1的内容。我知道有一些代码要写在客户端上，以便在头文件中发送0。

我在我的wcf服务中使用消息合同而不是数据合同。我明白，对于某些属性我可以去添加像这个链接https://docs.microsoft.com/en-us/dotnet/api/system.servicemodel.messageheaderattribute.mustunderstand?view=netframework-4.7.2这样的属性。但我不是要添加任何属性。我只是将它添加到soapenv中的第一个linke：mustunderstand = 1

请帮忙！。

谢谢

不确定这是否可以解决您的问题。但您可以尝试在web.config中添加标头。

  <endpoint address="http://ws-wuxipc-5077:4000/calculator" binding="basicHttpBinding"
  contract="ServiceInterface.ICalculatorService" name="cal">
  <headers>
    <Security xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" >
      <wsse:UsernameToken xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
        xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
        <wsse:Username>
        </wsse:Username>
        <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">monMonDePasse</wsse:Password>
        <wsse:Nonce>sdsdsdlojhfdsdM5Nw==</wsse:Nonce>
        <wsu:Created>2019-01-21T6:17:34Z</wsu:Created>
      </wsse:UsernameToken>
    </Security>
  </headers>
</endpoint>

或者您可以使用代码添加标头。

 using (ChannelFactory<ICalculatorService> ChannelFactory = new ChannelFactory<ICalculatorService>("cal"))
    {
                        ICalculatorService employeeService = ChannelFactory.CreateChannel();
        using (OperationContextScope scope = new OperationContextScope((IContextChannel)employeeService))
        {

            System.Xml.XmlDocument document = new XmlDocument();


            XmlElement element = document.CreateElement("wsse", "UsernameToken", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");


            XmlElement newChild = null;

            newChild = document.CreateElement("wsse", "Username", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
            newChild.InnerText = "finance";
            element.AppendChild(newChild);

            newChild = document.CreateElement("wsse", "password", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
            newChild.SetAttribute("Type", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest");
            newChild.InnerText = "387";
            element.AppendChild(newChild);

            MessageHeader messageHeader = MessageHeader.CreateHeader("security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", element, false); // here is mustunderstood is set to false


            OperationContext.Current.OutgoingMessageHeaders.Add(messageHeader);

        }

                       Console.Read();
    }
