如何创建 SOAP 请求，简单的方法

Question

我是 SOAP 新手，
我正在硬编码 SOAP 请求并发送到服务器，它工作正常。现在我想动态创建 SOAP 请求，因为我是 SOAP 新手，我不知道 要准备 XML 我使用 jaxb ，我应该使用相同的方法来创建 SOAP 请求还是有更好的方法？

我的 Java 代码

public class Test {

public static void main(String[] args) {

    String xml ="<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\">\n"
            + "   <soapenv:Header/>\n"
            + "   <soapenv:Body>\n"
            + "      <tem:RequestData>\n"
            + "         <!--Optional:-->\n"
            + "         <tem:requestDocument>\n"
            + "\n"
            + "\n"
            + "<![CDATA[ <Request>\n"
            + "<Authentication CMId='68' Guid='5594FB83-F4D4-431F-B3C5-EA6D7A8BA795' Password='poihg321TR' Function='1' />\n"
            + "<Establishment Id='4297867' >\n"
            + "</Establishment>\n"
            + "</Request> ]]> \n"
            + "\n"
            + "\n"
            + "</tem:requestDocument>\n"
            + "      </tem:RequestData>\n"
            + "   </soapenv:Body>\n"
            + "</soapenv:Envelope>";




    sendRequestToChannel(xml);
}

private static String sendRequestToChannel(String request) {

    String xmlData = null;
    BufferedReader rd = null;
    BufferedWriter bw = null;

有多种框架可用于此

Answer 2

尝试使用“javax.xml.soap”包的类。

public String cretaeSOAPMessage(Document soapBodyDoc, String serverURI,
        String soapAction, String bodyNameSpace) {
    String soapMsg = null;      
    try {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();
        SOAPEnvelope envelope = soapPart.getEnvelope();


        SOAPBody soapBody = envelope.getBody(); 
        soapBody.addNamespaceDeclaration("tem", bodyNameSpace);
        soapBody.addDocument(soapBodyDoc);          


        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", serverURI + soapAction);;

        soapMessage.saveChanges();


        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try {
            soapMessage.writeTo(out);
        } catch (IOException e) {
            e.printStackTrace();
        }
        soapMsg = new String(out.toByteArray());


    } catch (SOAPException e) {
        e.printStackTrace();
    }

    return soapMsg;
}

soapBodyDoc : org.w3c.dom.Document 表示里面的数据

serverURI：你的目标名称空间

soapAction: wsdl:操作

bodyNameSpace: "http://tempuri.org/"

不能说它是否比 JAXB 更好。但是在您的其他一篇文章中，我可以看到您正在努力使用 JAXB 包含 CDATA 部分。这个逻辑可能会帮助你摆脱困境。

此时您可能会遇到一些问题

soapBody.addDocument(soapBodyDoc);

如果是这样，不要将整个正文内容添加为文档，而是在其中创建正文。 为此，请使用以下代码示例

SOAPElement soapBodyElem = soapBody.addChildElement("RequestData", "tem");
soapBodyElem.addChildElement("requestDocument","tem");

soapBodyElem.addTextNode("<![CDATA[ <Request>....");
