从WSE 3.0客户端请求删除的WS-Addressing / WS-Security的部分 [英] Remove WS-Addressing/WS-Security sections from WSE 3.0 Client request

问题描述

我已经得到了我WSDL.EXE创建了一个简单的C＃Web服务代理类。我对远程Web服务调用的方法，它包括一组WS-Addressing和我不希望（和服务器窒息）的WS-Security头。这里是原始皂请求的示例：

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:

<?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>

但我不关心的WS-Addressing / WS-Security的东西。我还没有做什么，包括它。在.NET WSE 3.0包似乎被默认添加。有什么办法来摆脱这些？我可以看到我的代理对象没有属性，让我删除这些部分。我试过：

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:

proxyObject.Addressing.Clear();
proxyObject.Security.Clear();

那些导致空引用异常，当我调用我的Web服务方法。

Those cause a null reference exception when I invoke my web service method.

我要的SOAP请求如下：

I want the SOAP request to look like this:

<?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>

在此先感谢

推荐答案

好吧，我结束了使用我已经在过去使用的技术。我创建了一个实现类 SoapFilter 和 PolicyAssertion ，允许在发送前我修改的SOAP请求的原始XML。下面是一个例子：

Well, I ended up using a technique I have used in the past. I created classes that implement SoapFilter and PolicyAssertion which allow me to modify the raw XML of the SOAP request before it is sent. Below is an example:

    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;
        }
    }

然后在你的web服务代理的构造器，你应用策略：

Then in your web service proxy's contructor you apply the policy:

/// <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); 
        }
  }
