Remove WS-Addressing/WS-Security sections from WSE 3.0 Client request
提问by Mike Marshall
I've got a simple C# web service proxy class that I created with WSDL.exe. I am invoking a method on the remote web service, and it is including a bunch of WS-Addressing and WS-Security headers that I do not want (and that the server is choking on). Here is an example of the raw soap request:
我有一个使用 WSDL.exe 创建的简单 C# Web 服务代理类。我正在调用远程 Web 服务上的一个方法，它包含一堆我不想要的 WS-Addressing 和 WS-Security 标头（并且服务器正在窒息）。这是原始肥皂请求的示例：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing"
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">
<soap:Header>
<wsa:Action></wsa:Action>
<wsa:MessageID>urn:uuid:22f12267-b162-4703-a451-2d1c5c5a619b</wsa:MessageID>
<wsa:To>http://example.com/wstest</wsa:To>
<wsse:Security>
<wsu:Timestamp wsu:Id="Timestamp-5c9f0ef0-ab45-421d-a633-4c4fad26d945">
<wsu:Created>2009-04-15T16:27:25Z</wsu:Created>
<wsu:Expires>2009-04-15T16:32:25Z</wsu:Expires>
</wsu:Timestamp>
</wsse:Security>
</soap:Header>
<soap:Body>
<Func1 xmlns="http://example.com">
<arg_1 xmlns="">blah</arg_1>
<arg_2 xmlns="">blah2</arg_2></arg_2>
</Func1>
</soap:Body>
</soap:Envelope>
But I don't care about the WS-Addressing/WS-Security stuff. I've done nothing to include it. The .NET WSE 3.0 package seems to be adding them by default. Is there any way to get rid of these? I can see no properties on my proxy object that allow me to remove these sections. I've tried:
但我不关心 WS-Addressing/WS-Security 的东西。我没有做任何事情来包含它。.NET WSE 3.0 包似乎默认添加它们。有没有办法摆脱这些？我在代理对象上看不到任何允许我删除这些部分的属性。我试过了：
proxyObject.Addressing.Clear();
proxyObject.Security.Clear();
Those cause a null reference exception when I invoke my web service method.
当我调用我的 Web 服务方法时，这些会导致空引用异常。
I want the SOAP request to look like this:
我希望 SOAP 请求如下所示：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Header>
</soap:Header>
<soap:Body>
<Func1 xmlns="http://example.com">
<arg_1 xmlns="">blah</arg_1>
<arg_2 xmlns="">blah2</arg_2></arg_2>
</Func1>
</soap:Body>
</soap:Envelope>
Thanks in advance

Well, I ended up using a technique I have used in the past. I created classes that implement SoapFilterand PolicyAssertionwhich allow me to modify the raw XML of the SOAP request before it is sent. Below is an example:
好吧，我最终使用了我过去使用过的技术。我创建了实现SoapFilter和PolicyAssertion 的类，它们允许我在发送之前修改 SOAP 请求的原始 XML。下面是一个例子：
public class MyPolicy : SoapFilter
{
public override SoapFilterResult ProcessMessage(SoapEnvelope envelope)
{
// Remove all WS-Addressing and WS-Security header info
envelope.Header.RemoveAll();
return SoapFilterResult.Continue;
}
}
public class MyAssertion : PolicyAssertion
{
public override SoapFilter CreateClientInputFilter(FilterCreationContext context)
{
return null;
}
public override SoapFilter CreateClientOutputFilter(FilterCreationContext context)
{
return new MyPolicy();
}
public override SoapFilter CreateServiceInputFilter(FilterCreationContext context)
{
return null;
}
public override SoapFilter CreateServiceOutputFilter(FilterCreationContext context)
{
return null;
}
}
Then in your web service proxy's contructor you apply the policy:
然后在您的 Web 服务代理的构造函数中应用该策略：
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Web.Services", "2.0.50727.1433")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="MyBinding", Namespace="http://example.com")]
public partial class MyWebClient : WebServicesClientProtocol {
// ... member variables here
/// <remarks/>
public MyWebClient()
{
this.Url = "http://example.com";
if ((this.IsLocalFileSystemWebService(this.Url) == true)) {
this.UseDefaultCredentials = true;
this.useDefaultCredentialsSetExplicitly = false;
}
else {
this.useDefaultCredentialsSetExplicitly = true;
}
// Apply policy here
Policy policy = new Policy();
policy.Assertions.Add(new MyAssertion());
this.SetPolicy(policy);
}
}

I wonder if your problem might not also have ben resolved by simply not using WSE?
我想知道您的问题是否也不能通过不使用 WSE 来解决？

Based on the answer in this page, I added the code below to remove specific header (by tagname) recursively from XML.
根据此页面中的答案，我添加了以下代码以从 XML 递归删除特定标头（按标记名）。
Public Overrides Function ProcessMessage(ByVal envelope As SoapEnvelope) As SoapFilterResult
' Remove all WS-Addressing and WS-Security header info
RemoveTag(envelope.DocumentElement, "wsa:Action")
RemoveTag(envelope.DocumentElement, "wsa:MessageID")
RemoveTag(envelope.DocumentElement, "wsa:To")
Return SoapFilterResult.[Continue]
End Function
Private Sub RemoveTag(ByVal XE As System.Xml.XmlElement, ByVal TagName As String)
For Each N As XmlNode In XE
If N.ChildNodes.Count > 0 Then
RemoveTag(N, TagName)
End If
If N.Name = TagName Then
XE.RemoveChild(N)
End If
Next
End Sub

I found the easiest way to remove these addressing and security headers was to change the web service configuration to use BasicHttpBindinginstead of WSHttp binding.
我发现删除这些寻址和安全标题最简单的方法是改变Web服务配置中使用BasicHttpBinding的替代WSHttp binding。
回答by ClearLogic
to remove the addressing header i used the below code in one of my app.
要删除寻址标头，我在我的应用程序之一中使用了以下代码。
public override void SecureMessage(SoapEnvelope envelope, Security security)
{
//remove addressing Header from envelope
AddressingHeaders objAH = new AddressingHeaders(envelope);
objAH.RemoveXml(envelope);
//Add Wahtever security token you want to add.
security.Tokens.Add(bla-bla-bla);
}
I used SecureMessagefunction because i wanted to add security tokens,but same code can be used in ProcessMessagefunction.
我使用SecureMessage函数是因为我想添加安全令牌，但在ProcessMessage函数中可以使用相同的代码。
