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，他们通过 SOAP 标头传递用户名令牌。
WCF 服务托管在启用了 SSL 的 IIS 服务器上。
至此，我已经有了一个半工作原型。我现在处理的问题是 SOAP 标头的 MustUnderstand 属性设置为 1，这会导致该过程失败。
我想要一些建议（或者更好的是，一个代码示例smiles）了解如何处理用户名标记，以便在 MustUnderstand 属性为 true 时返回正确的响应。
以下是失败的 SOAP 请求的示例：
<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：这是客户发送的修改后的示例请求：
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header>
<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/WService/Getstuff</Action>

</s:Header>
<s:Body>
<Getstuff xmlns="http://tempuri.org/">

<Arg2>Arg2</Arg2>
</Getstuff>
</s:Body>
</s:Envelope>
我收到对上述请求的以下答复：
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
