java - Twinfield - 服务器无法识别 HTTP header SOAPAction 的值

Question

我正在尝试连接 Twinfield logon api通过Java。我试过的代码是

import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.MimeHeaders;
import java.io.ByteArrayInputStream;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;

public class SoapTest {

    public static void main(String[] args) {
        try {
            SOAPConnectionFactory sfc = SOAPConnectionFactory.newInstance();
            SOAPConnection connection = sfc.createConnection();

            MessageFactory mf = MessageFactory.newInstance();
            SOAPMessage sm = mf.createMessage();

            SOAPHeader sh = sm.getSOAPHeader();
            SOAPBody sb = sm.getSOAPBody();
            //sh.detachNode();
            QName logonName = new QName("http://www.twinfield.com", "Logon");
            SOAPBodyElement logonElement = sb.addBodyElement(logonName);

            QName userTag = new QName("user");
            SOAPElement user = logonElement.addChildElement(userTag);
            user.addTextNode("myuser");

            QName passwordTag = new QName("password");
            SOAPElement password = logonElement.addChildElement(passwordTag);
            password.addTextNode("mypassword");

            QName organisationTag = new QName("organisation");
            SOAPElement organisation = logonElement.addChildElement(organisationTag);
            organisation.addTextNode("myorg");

            System.out.println("\n Soap Request:\n");
            sm.writeTo(System.out);
            System.out.println();

            URL endpoint = new URL("https://login.twinfield.com/webservices/session.asmx");
            SOAPMessage response = connection.call(sm, endpoint);

            connection.close();

            //System.out.println(response.getContentDescription());
            //System.out.println("--------------------------");

            // Reading response
            printSOAPResponse(response);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    private static void printSOAPResponse(SOAPMessage soapResponse) throws Exception {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source sourceContent = soapResponse.getSOAPPart().getContent();
        System.out.print("\nResponse SOAP Message = ");
        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
    }   
}

似乎一切都是正确的，但我经常收到回复 <faultstring>Server did not recognize the value of HTTP Header SOAPAction: .</faultstring> .上述程序的完整输出如下:

java SoapTest

 Soap Request:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
    <SOAP-ENV:Body>
        <Logon xmlns="http://www.twinfield.com">
            <user>NLG001136</user>
            <password>qura976yj</password>
            <organisation>TWF-SAAS</organisation>
        </Logon>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Response SOAP Message = 
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Client</faultcode>
            <faultstring>Server did not recognize the value of HTTP Header SOAPAction: .</faultstring>
            <detail/>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

相同的请求/凭据在 Soapclient.com 上运行良好.有人可以指出我的程序哪里出错了吗？

因为故障代码是客户端，所以是您发送的 soap 消息导致了问题。尝试使用 SOAP UI 传递相同的内容，我尝试将 WSDL 导入到我的 SOAP UI 中，但出现附加错误...

加载错误 [ https://login.twinfield.com/webservices/session.asmx?wsdl] : org.apache.xmlbeans.XmlException: org.apache.xmlbeans.XmlException: 错误: 不关闭标签

由于显示的 Web 服务是文档/文字包装的，只需尝试使用 wsimport 创建 hte 客户端代码，您将拥有所有需要的文件，并且可以轻松发送相同的请求。

如果您只对 SAAJ 方式感兴趣，那么我会尝试传递通过 SOAP UI 创建的消息。

希望这对您有所帮助。
