如何使用wsdl生成的java对象发出soap请求时添加soap标头

Question

我使用JAX-WS RI生成了客户端java对象.我正在尝试向Web服务发出SOAP请求.服务需要在标头中进行身份验证,如下所示:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<xsd:authHeader>
<xsd:user>username@gmail.com</xsd:user>
<xsd:password>password1</xsd:password>
</xsd:authHeader>
</soapenv:Header>
<soapenv:Body>
<ns:searchAssetsParam>
<ns:includeSubfolders>true</ns:includeSubfolders>
<ns:resultsPage>2</ns:resultsPage>
</ns:searchAssetsParam>
</soapenv:Body>
</soapenv:Envelope>

生成的java对象具有调用服务,创建对象和构造头的方法.但是,我在拨打电话时设置标头时遇到问题.

这是我正在使用的代码:

IpsApiService service = new IpsApiService();
IpsApiPortType port = service.getIpsApiSoapPort();
SearchAssetsParam searchAssetsParam = buildSearchAssetsParam();
SearchAssetsReturn response = port.searchAssets(searchAssetsParam);

buildSearchAssetsParam()构造请求对象.我创建了头对象,如下所示:

AuthHeader header = new AuthHeader();
header.setUser("username@gmail.com");
header.setPassword("password1");

如何将此AuthHeader设置为服务请求？

谢谢,Venu

一旦我遇到同样的问题.我需要JAX-WS在每次请求时修改Web服务SOAP标头.为了解决这个问题,我创建了一个这样的处理程序:

public class MyHandler implements SOAPHandler<SOAPMessageContext> {

    private static final Logger LOGGER = LoggerFactory.getLogger(MyHandler.class);

    private String username;

    private String password;

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        try {
            SOAPMessage message = context.getMessage();
            SOAPHeader header = message.getSOAPHeader();
            SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
            if (header == null) {
                header = envelope.addHeader();
            }
            QName qNameUserCredentials = new QName("https://your.target.namespace/", "UserCredentials");
            SOAPHeaderElement userCredentials = header.addHeaderElement(qNameUserCredentials);

            QName qNameUsername = new QName("https://your.target.namespace/", "Username");
            SOAPHeaderElement username = header.addHeaderElement(qNameUsername );
            username.addTextNode(this.username);
            QName qNamePassword = new QName("https://your.target.namespace/", "Password");
            SOAPHeaderElement password = header.addHeaderElement(qNamePassword);
            password.addTextNode(this.password);

            userCredentials.addChildElement(username);
            userCredentials.addChildElement(password);

            message.saveChanges();
            //TODO: remove this writer when the testing is finished
            StringWriter writer = new StringWriter();
            message.writeTo(new StringOutputStream(writer));
            LOGGER.debug("SOAP message: \n" + writer.toString());
        } catch (SOAPException e) {
            LOGGER.error("Error occurred while adding credentials to SOAP header.", e);
        } catch (IOException e) {
            LOGGER.error("Error occurred while writing message to output stream.", e);
        }
        return true;
    }

    //TODO: remove this class after testing is finished
    private static class StringOutputStream extends OutputStream {

        private StringWriter writer;

        public StringOutputStream(StringWriter writer) {
            this.writer = writer;
        }

        @Override
        public void write(int b) throws IOException {
            writer.write(b);
        }
    }

    @Override
    public boolean handleFault(SOAPMessageContext context) {
        LOGGER.debug("handleFault has been invoked.");
        return true;
    }

    @Override
    public void close(MessageContext context) {
        LOGGER.debug("close has been invoked.");
    }

    @Override
    public Set<QName> getHeaders() {
        LOGGER.debug("getHeaders has been invoked.");
        return null;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

它将所需的参数添加到我的SOAP标头中,并在每个请求时调用它.您需要做的就是修改handleMessage方法以满足您的需求.
