java - 使用JAVA解析SOAP响应并提取特定节点

Question

我正在尝试与 SOAP 服务交互。我能够获取 SOAP 响应，并通过使用 Source sourceContent =soapResponse.getSOAPPart().getContent(); 和 transformer.transform(sourceContent, result); ，我能够看到输出/响应是什么并将其显示在控制台中。

但是，我需要从响应中提取 sessionID 并在不同的 SOAP 请求中发送该 sessionID。

请建议我提取方法，构建新的 SOAP 请求

解析是我需要做的!!

下面是将请求发送到 SOAP 服务的代码:

public static void main(String args[]) {
    try {
        // Create SOAP Connection
        SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection soapConnection = soapConnectionFactory.createConnection();

        // Send SOAP Message to SOAP Server
        String url = "https://WWW.DUMMYURL.COM";
        SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);


        // Process the SOAP Response
        printSOAPResponse(soapResponse);

        soapConnection.close();
     } 

    catch (Exception e) {
        System.err.println("Error occurred while sending SOAP Request to Server");
        e.printStackTrace();
    }
 }

    private static SOAPMessage createSOAPRequest() throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();
        String serverURN = "urn:DUMMYURL.COM";
        String serverNS0 = "http://WWW.DUMMYURL.COM";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("urn", serverURN);
        envelope.addNamespaceDeclaration("ns0", serverNS0);

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();     
        SOAPElement soapBodyElem1 = soapBody.addChildElement("login","urn");
        SOAPElement soapBodyElem2 = soapBodyElem1.addChildElement("username","urn");
        @SuppressWarnings("unused")
        SOAPElement soapBodyElem3 = soapBodyElem2.addTextNode("USERNAME");
        SOAPElement soapBodyElem4 = soapBodyElem1.addChildElement("password","urn");
        @SuppressWarnings("unused")
        SOAPElement soapBodyElem5 = soapBodyElem4.addTextNode("PASSWORD");
        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", "https://WWW.DUMMYURL.COM"  + "login");
        soapMessage.saveChanges();

        //Print the request message
        System.out.print("Request SOAP Message = ");
        soapMessage.writeTo(System.out);
        System.out.println();
        return soapMessage;
}


    private static void printSOAPResponse(SOAPMessage soapResponse) throws Exception {  

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source sourceContent = soapResponse.getSOAPPart().getContent();
        String source = sourceContent.toString();
        System.out.print("\nResponse SOAP Message = ");

        // Format it
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
        System.out.println(transformer.toString());
}

有人可以建议我一个关于如何将我收到的响应保存到本地文件的片段吗？

目前，在上面的代码中，响应正在控制台中显示。

您可以使用 SOAPMessage 接口(interface)的 writeTo 方法来执行相同的操作，例如:

FileOutputStream out = new FileOutputStream("somefile");
soapResponse.writeTo(out);
