java - Axis2 客户端抛出 AxisFault : Must Understand check failed for header Security

Question

我使用的是 Axis2-1.6.1，并且能够成功发送 SOAP 请求。这是请求的示例:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
  <soapenv:Header>
    <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" soapenv:mustUnderstand="true">
      <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
        <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">***pass***</wsse:Password>
        <wsse:Nonce Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">***nonce***</wsse:Nonce>
        <wsu:Created Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">***datetime***</wsu:Created>
      </wsse:UsernameToken>
    </wsse:Security>
    <wsa:Action xmlns:wsa="http://www.w3.org/2005/08/addressing">http://mysite/contract/users/v3/IUsers/EchoAuthenticated</wsa:Action>
  </soapenv:Header>
  <soapenv:Body>
    <ns6:EchoAuthenticated xmlns:ns6="http://mysite/contract/users/v3">
      <ns6:value>success</ns6:value>
    </ns6:EchoAuthenticated>
  </soapenv:Body>
</soapenv:Envelope>

收到响应后，抛出此异常:

org.apache.axis2.AxisFault: Must Understand check failed for header http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd : Security

我的印象是，在进行一些研究之后，Axis2 不喜欢响应中的某些内容。感到困惑，我复制了上面的请求并将其粘贴到 SoapUI 中并触发了它。它有效，我收到以下回复。我还使用 Fiddler 确认，这与我在 Eclipse 中发送此请求时收到的响应相同，只是 Axis2 不喜欢客户端，也许是 mustUnderstand？

这是响应:

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
  <s:Header>
    <a:Action s:mustUnderstand="1">http://mysite/contract/users/v3/IUsers/EchoAuthenticatedResponse</a:Action>
    <a:RelatesTo>urn:uuid:***guid***</a:RelatesTo>
    <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
      <u:Timestamp u:Id="_0">
        <u:Created>***datetime***</u:Created>
        <u:Expires>***datetime***</u:Expires>
      </u:Timestamp>
    </o:Security>
  </s:Header>
  <s:Body>
    <EchoAuthenticatedResponse xmlns="http://mysite/contract/users/v3">
      <EchoAuthenticatedResult>This is the Users service answering back. The value you sent was: success</EchoAuthenticatedResult>
    </EchoAuthenticatedResponse>
  </s:Body>
</s:Envelope>

我迁移到更新版本的 Axis2 的能力有限，因为它与产品捆绑在一起，但我需要找出如何解决此错误。

Answer 1

我找到了一种解决方案，即在对 false 的响应中设置 mustUnderstand 实例

为此，我做了以下工作:

---

1. 创建一个扩展 *org.apache.axis2.handlers.AbstractHandler 的处理程序类

MustUnderstandHandler.java

import java.util.Iterator;

import org.apache.axiom.soap.SOAPEnvelope;
import org.apache.axiom.soap.SOAPHeader;
import org.apache.axiom.soap.SOAPHeaderBlock;
import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;

public class MustUnderstandHandler extends org.apache.axis2.handlers.AbstractHandler  {

  @Override
  public InvocationResponse invoke(MessageContext messageContext) throws AxisFault {
    
    try{
      
      System.out.println("RemoveMustUnderstandAll: invoke " + messageContext);
      
      SOAPEnvelope env = messageContext.getEnvelope();
      SOAPHeader header = env.getHeader();
      
      if(header != null){
        
          for(Iterator<?> itr = header.getChildElements(); itr.hasNext();){
            
              SOAPHeaderBlock headerBlock = (SOAPHeaderBlock) itr.next();
              
              if(headerBlock.getMustUnderstand()){
                
                headerBlock.setMustUnderstand(false);
                System.out.println("RemoveMustUnderstandAll (" + messageContext + "): setMustUnderstand(false) to " + headerBlock.getQName());
              }
          }
      }
    }
    catch(Exception e){

      System.out.println(e.toString());
    }
    
    return InvocationResponse.CONTINUE;
  }
}

1. 连接 AxisConfiguration 以使用处理程序类

在生成的 stub (从 WSDL2Java 创建)中，我找到了它正在执行客户端的实例，并且在每一行之前我包含了以下内容:

MyStub.java

AxisConfiguration axisConfiguration = _messageContext.getConfigurationContext().getAxisConfiguration();
ArrayList arrayList = new ArrayList();
arrayList.add(new MustUnderstandHandler());
axisConfiguration.setInPhasesUptoAndIncludingPostDispatch(arrayList);

// execute the operation client
_operationClient.execute(true);
