如何从骆驼的交换对象中检索 SOAP 标头？

Question

• We exposed an Apache camel-cxf webservice. Using camel processor we are trying to get the soap header that we passed in the soap request from the soapUi client.

• The exchange object contains the body of soap message(not soap header). In the exchange.getIn.getHeader() we are only getting the HTTP Headers we passed, not the SOAP Header.

• How to retrieve the SOAP header from exchange obeject in Camel ?

• Following are the soap header passed:

 <soapenv:Header> <ns1:info xmlns:ns1="http://www.w3schools.com/transaction/"> <ns1:TransactionID>01</ns1:TransactionID> <ns1:AppUserID>52</ns1:AppUserID> <ns1:AppPass>ab</ns1:AppPass> </ns1:info> </soapenv:Header>

• We tried using,

  • exchange.getIn().getHeaders();

  • exchange.getIn().getHeader(“TransactionID”);

    However it was not able to extract the SOAP header which was sent.

• How to add custom soap headers in Payload mode ?

Answer 1

If cxf endpoint configured to working in DataFormat.PAYLOAD so:

 .process(exchange -> {
                CxfPayload body = exchange.getIn().getBody(CxfPayload.class);
                for (Object header : body.getHeaders()) {
                    SoapHeader soapHeader = (SoapHeader) header;
                    org.w3c.dom.Element element = (Element) soapHeader.getObject();
                    //parse elements
                }
            });

If in raw mode, just read input stream and parsing data as xml using xpath

UPD:

Example route:

CxfEndpoint endpoint = new CxfEndpoint();
    endpoint.setDataFormat(DataFormat.PAYLOAD);
    endpoint.setWsdlURL("etc/Proxy.wsdl");
    endpoint.setAddress("http://localhost:8089/wsservice/");
    getContext().getRegistry().bind("cxfend", endpoint);
    from("cxf:bean:cxfend")
            .process(exchange -> {
                CxfPayload body = exchange.getIn().getBody(CxfPayload.class);
                for (Object header : body.getHeaders()) {
                    SoapHeader soapHeader = (SoapHeader) header;
                    org.w3c.dom.Element element = (Element) soapHeader.getObject();
                    Element transactionID = (Element) element.getElementsByTagName("ns1:TransactionID").item(0);
                    log.info("Header TransactionID with value:{}", transactionID.getTextContent());
                }
            });

Output:

- Header TransactionID with value:01

Answer 2

That was my solution:

    List<SoapHeader> soapHeaders = (List)exchange.getIn().getHeader("org.apache.cxf.headers.Header.list");
    Element header = ((Element)soapHeaders.get(0).getObject());
    String eventType = (String)header.getElementsByTagName("TransactionID").item(0).getTextContent();
    exchange.getIn().setHeader("TYPE_EVENT",eventType);
