向请求添加自定义标头时出现轴 2 和壁垒问题答案

【问题标题】：Axis 2 and rampart issue while adding cutom header to the request向请求添加自定义标头时出现轴 2 和壁垒问题
【发布时间】：2013-02-13 11:47:13
【问题描述】：

<soapenv:Envelope> 
<soapenv:Header>    
      <cor:india>test</cor:india>
     </soapenv:Header>

<soapenv:Body>
.
.
</soapenv:Body>
</soapenv:Envelope>

     OMFactory omFactory =OMAbstractFactory.getOMFactory();
    OMNamespace omNamespace = omFactory.createOMNamespace("http://example.com/...", "cor");
    OMElement header = omFactory.createOMElement("india", omNamespace);
    header.setText("test");
    stub._getServiceClient().addHeader(header);

我想将自定义标头添加到使用轴 2 和壁垒的肥皂请求中。但下面是我得到的例外

【问题讨论】：

我遇到了同样的错误。但我没有发现错误请给我示例应用程序
@sureshmanda，您是否正在通过轴 2 在soap 请求中添加额外的标头信息，例如：“test”？
是的，但我不喜欢这种。
您必须添加名称空间并将内容添加到答案部分中显示的标题中。这是它的代码。 OMNamespace ns = factory.createOMNamespace("google.com", "cor"); hdr.addHeaderBlock("印度", ns).setText("这里的值");

【解决方案1】：

如果您尝试使用此处提供的提示添加标题 Example Custom Headers 并且您使用壁垒参与的位置，那么您将面临上述问题。

解决方案是在 META-INF 中添加您自己的 module.xml，并在添加自定义标头的位置添加输出流

<module name="test" class="exampleClass">

    <OutFlow>

            <handler name="handle" class="exampleClass">
                <order phase="Security"  />
            </handler>
        </OutFlow>
</module>

================================================ ====================================

public class exampleClass AbstractHandler implements org.apache.axis2.modules.Module {

public InvocationResponse invoke(MessageContext ctx) throws AxisFault {

SOAPEnvelope env = ctx.getEnvelope();
SOAPHeader hdr = env.getHeader();

SOAPFactory factory = (SOAPFactory) env.getOMFactory();

OMNamespace ns = factory.createOMNamespace("http://google.com", "cor");

//SOAPHeader head = factory.createSOAPHeader(env);

hdr.addHeaderBlock("india", ns).setText("value here");

return InvocationResponse.CONTINUE;
}


public void applyPolicy(Policy arg0, AxisDescription arg1) throws AxisFault {
    // TODO Auto-generated method stub

}

public boolean canSupportAssertion(Assertion arg0) {
    // TODO Auto-generated method stub
    return false;
}

public void engageNotify(AxisDescription arg0) throws AxisFault {
    // TODO Auto-generated method stub

}

public void init(ConfigurationContext arg0, AxisModule arg1) throws AxisFault {
    // TODO Auto-generated method stub

}

public void shutdown(ConfigurationContext arg0) throws AxisFault {
    // TODO Auto-generated method stub

} }

================================================ ===================================

在客户端加入你的模块之前，像壁垒一样

Options options = serviceClient.getOptions();
serviceClient.engageModule("test");

options.setProperty(RampartMessageData.KEY_RAMPART_POLICY,loadPolicy("policy.xml"));
serviceClient.engageModule("rampart");
..
