WCF-Soap头在安全元素中引用命名空间两次

Question

这是一个有点乏味的问题...我已经建立了一个WCF来使用WS-Security，在我的日志中看起来像这样：

<h:Security xmlns:h="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" 
              xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
  <UsernameToken>
    <Username>
      <!-- Removed-->
    </Username>
    <Password>
      <!-- Removed-->
    </Password>
  </UsernameToken>
</h:Security>

问题是，为什么同一个名称空间会被引用两次（“http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd我知道，只要元素引用的是正确的名称空间，同一名称空间是否被引用两次其实并不重要，但我确实想知道它为什么会这样做。

我的代码：

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.MessageContractAttribute(IsWrapped = false)]
public partial class InventoryCountRequest
{

  [System.ServiceModel.MessageHeaderAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
  public Security Security;

  //Other MessageHeader and MessageBody attributes
}

[System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "3.0.4506.2152")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
public partial class Security
{
  private UsernameToken usernameTokenField;

    [System.Xml.Serialization.XmlElementAttribute(Order = 0)]
    public UsernameToken UsernameToken
    {
       get{return this.usernameTokenField;}
       set{this.usernameTokenField = value;}
    }
}

public partial class UsernameToken
{
  private string usernameField;
  private Password passwordField;

  [System.Xml.Serialization.XmlElementAttribute(Order = 0)]
  public string Username
  {
    get{return this.usernameField;}
    set{this.usernameField = value;}
  }

  [System.Xml.Serialization.XmlElementAttribute(Order = 1)]
  public Password Password
  {
    get{return this.passwordField;}
    set{this.passwordField = value;}
  }
}

[System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "3.0.4506.2152")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
public partial class Password
{
  private string typeField;
  private string valueField;

  [System.Xml.Serialization.XmlAttributeAttribute()]
  public string Type
  {
    get{return this.typeField;}
    set{this.typeField = value;}
  }

  [System.Xml.Serialization.XmlTextAttribute()]
  public string Value
  {
    get{return this.valueField;}
    set{this.valueField = value;}
  }
}

也许这不是网络上消息的样子。可能是WCF日志查看器添加了它（你可以看到它删除了密码后做了一些操作）。使用Fiddler看看真正的消息是什么样子。

然后您手动（通过数据合同）添加安全头。一般来说，WCF可以通过绑定的配置来配置。所以也许WCF识别一个安全头，并总是给它附加一些命名空间。

我不会担心的。
