java - 发出 SOAP API 调用时出现 400 错误请求

Question

我在调用 SOAP API 时遇到问题。我收到 400 Bad Request 消息。我不确定为什么我会得到这种糟糕的 react 。我正在关注由软件公司直接获得的 API 文档。

我的测试类:

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.MimeHeader;
import javax.xml.soap.MimeHeaders;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPConstants;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;

public class TestClass {


    public static void main(String args[]) {
        String soapEndpointUrl = "https://telehealth.foracare.com/WebService/WS_DataInterchangeService.asmx";
        String soapAction = "http://www.tdcare.com/DataInterchange";
        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static SOAPMessage createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String targetNamespace = "http://www.tdcare.com/";

        String xsi = "xsi";
        String xsiURI = "http://www.w3.org/2001/XMLSchema-instance";

        String xsd = "xsd";
        String xsdURI = "http://www.w3.org/2001/XMLSchema";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(xsi, xsiURI);
        envelope.addNamespaceDeclaration(xsd, xsdURI);



        //SOAP Header
        SOAPHeader soapHead = envelope.getHeader();
        QName qname = new QName(targetNamespace, "sValidationSoapHeader", new String());
        SOAPElement soapHeadElem = soapHead.addChildElement(qname);
        SOAPElement soapHeadElem1 =  soapHeadElem.addChildElement("Username");
        soapHeadElem1.addTextNode("****");
        SOAPElement soapHeadElem2 =  soapHeadElem.addChildElement("Password");
        soapHeadElem2.addTextNode("*****");

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        QName dataInterchangeQName = new QName(targetNamespace, "DataInterchange", new String());
        SOAPElement dataInterchange = soapBody.addChildElement(dataInterchangeQName);
        SOAPElement iCMDType = dataInterchange.addChildElement("iCMDType");
        iCMDType.addTextNode("Q0001");
        SOAPElement iData = dataInterchange.addChildElement("iData");
        SOAPElement queryData = iData.addChildElement("QueryData");
        SOAPElement account = queryData.addChildElement("Account");
        account.addTextNode("*****");
        SOAPElement password = queryData.addChildElement("Password");
        password.addTextNode("******");
        SOAPElement qSDate = queryData.addChildElement("QSDate");
        qSDate.addTextNode("2010/01/01");
        SOAPElement qEDate = queryData.addChildElement("QEDate");
        qEDate.addTextNode("2010/02/01");
        SOAPElement qMType = queryData.addChildElement("QMType");
        qMType.addTextNode("1");
        SOAPElement qCase = queryData.addChildElement("QCase");
        return soapMessage;
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
        SOAPMessage soapMessage = messageFactory.createMessage();

        soapMessage =  createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("Host", "telehealth.foracare.com");
        headers.addHeader("SOAPAction", soapAction);
        headers.setHeader("Content-Type", "text/xml; charset=utf-8");
        soapMessage.saveChanges();

        Iterator i = headers.getAllHeaders();
        while(i.hasNext()) {
            MimeHeader header = (MimeHeader)i.next();
           System.err.println(header.getName() + " : "+ header.getValue());
        }

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }



}

这是我尝试遵循的示例 XML 请求:

这是我的代码构造的消息:

感谢任何帮助!

如果有效，请尝试这个。

String endPoint = "URL";

    SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
    SOAPConnection soapConnection = soapConnectionFactory.createConnection();

    String soapString = "Complete-SOAP String including Body/Header";

    InputStream is = new ByteArrayInputStream(soapString.getBytes());

    SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);

    MimeHeaders headers = request.getMimeHeaders();
    headers.addHeader("SOAPAction", "http://www.tdcare.com/DataInterchange");
    headers.setHeader("Content-Type", "application/xml");
    request.saveChanges();

    SOAPMessage soapResponse = soapConnection.call(request, endPoint);
    System.out.println(soapResponse);
