如何添加<soap:Envelope>和<soap:body>在 xml 請求中

Question

how to add <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-    instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"     xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> in xml soap request.

下面給出了我的示例請求。我創建了 jaxb 注釋類並將對象編組為 xml 格式，但是在向服務器發送請求之前，我需要在請求中添加上面的肥皂包和正文。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<StatusRequest>
<AccountID>231</AccountID>
<PassPhrase>sddddd</PassPhrase>
<StatusList>
<PICNumber>111111</PICNumber>
</StatusList>
<Test>Y</Test>
</StatusRequest>

請提供示例程序。

Answer 1

使用 javax.xml.soap。

您需要從要放入信封的對象中獲取一個 Document（在示例中使用 JAXB 對其進行編組）並將其放入正文中。

這樣：

MessageFactory mfactory = MessageFactory.newInstance();
SOAPMessage soapMessage = mfactory.createMessage();
SOAPBody soapBody = petition.getSOAPBody();
soapBody.addDocument(marshaller.marshallDoc(obj));
soapMessage.saveChanges();

當你這樣做時：

soapMessage.writeTo(System.out);

您將在輸出中看到 SOAP 部分。

Answer 2

SOAPPart soapPart = message.getSOAPPart();
// Obtain SOAP Part

SOAPEnvelope envelope = soapPart.getEnvelope();
// Obtain Envelope from SOAP Part

SOAPHeader header = envelope.getHeader();
// Obtain Header from Envelope

SOAPBody body = envelope.getBody();
// Obtain Body from Envelope

QName headerName = new QName("namespaceURI", "localPart");
// SOAPHeaderElement must have an associated QName object.

SOAPHeaderElement headerElement = header.addHeaderElement(headerName);
// Create new SOAPHeaderElement object initialized with the specified Qname
// and add it to this SOAPHeader object.

headerElement.addAttribute(new QName("localPart"), "valueToAdd");
// Add attribute to header  

 QName bodyName = new QName("namespaceURI", "localPart");
// SOAPBodyElement must have an associated QName object.

SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
// Add Body Element

假設req是一個由javax.xml.bind.annotation標記的類，那么：

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
marshaller.marshal(req, doc);

MessageFactory mfactory = MessageFactory.newInstance();
SOAPMessage soapMessage = mfactory.createMessage();
SOAPBody soapBody = soapMessage.getSOAPBody();
soapBody.addDocument(doc);

var baos = new ByteArrayOutputStream();
soapMessage.writeTo(baos);
var str = new String(baos.toByteArray(), Charset.forName("UTF8"));
log.info("SOAPMessage: {}", str);
