在 Java 中使用 SOAP Web 服务（具有安全性）

Question

我想 POST 将以下 XML 添加到 Web 服务 :-

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://<some_site>/retail/schema/inventory/orderlookupservice/v1">
      <soapenv:Header>
            <Security xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
                  <UsernameToken>
                        <Username>xyzUser</Username>
                        <Password>xyzPass</Password>
                  </UsernameToken>
            </Security>
      </soapenv:Header>
      <soapenv:Body>
            <v1:OrderSearchRequest>
                  <v1:RETAS400OrderNumber>1</v1:RETAS400OrderNumber>
            </v1:OrderSearchRequest>
      </soapenv:Body>
</soapenv:Envelope>

我期待以下回复 XML :-

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
      <soapenv:Header/>
      <soapenv:Body>
            <v1:OrderSearchResponse xmlns:v1="http://<some_site>/retail/schema/inventory/orderlookupservice/v1">
                  <v1:error>
                        <v1:errorCode>ERRODR01</v1:errorCode>
                        <v1:errorMessage>Order Number is Invalid</v1:errorMessage>
                  </v1:error>
            </v1:OrderSearchResponse>
      </soapenv:Body>
</soapenv:Envelope>

但是，我收到以下响应 XML，表明存在一些错误：-

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
   <env:Header>
   </env:Header>
   <env:Body>
      <env:Fault>
         <faultcode>env:Server
         </faultcode>
         <faultstring>
         </faultstring>
         <detail xmlns:fault="http://www.vordel.com/soapfaults" fault:type="faultDetails">
         </detail>
      </env:Fault>
   </env:Body>
</env:Envelope>

我正在使用 Java 8. 我尝试在两个不同的程序中使用 Apache HTTPClient（版本 4.4.1）和 SAAJ 进行 POST 操作，但无法修复这个。有人可以帮忙吗？

SAAJ代码如下:-

public class RequestInitiation {

    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 = "<service_endpoint>";
            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 serverURI = "http://<some_site>/retail/schema/inventory/orderlookupservice/v1";

        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("v1", serverURI);

        SOAPHeader header = envelope.getHeader();

        SOAPElement security =
                header.addChildElement("Security", "", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
        security.addAttribute(new QName("xmlns:wsu"), "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");

        SOAPElement usernameToken =
                security.addChildElement("UsernameToken", "");

        SOAPElement username =
                usernameToken.addChildElement("Username", "");
        username.addTextNode("xyzUser");

        SOAPElement password =
                usernameToken.addChildElement("Password", "");
        password.addTextNode("xyzPass");

        SOAPBody soapBody = envelope.getBody();

        SOAPElement soapBodyElem = soapBody.addChildElement("OrderSearchRequest", "v1");
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("RETAS400OrderNumber", "v1");
        soapBodyElem1.addTextNode("1");

        soapMessage.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-8");

        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();
        System.out.print("\nResponse SOAP Message = ");
        StreamResult result = new StreamResult(System.out);
        transformer.transform(sourceContent, result);
    }
}

HTTPClient代码如下:-

public class PostSOAPRequest {

    public static String post() throws Exception {

        HttpClient client = HttpClientBuilder.create().build();
        HttpPost post = new HttpPost("<service_endpoint>");
        String xml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:v1=\"http://<some_site>/retail/schema/inventory/orderlookupservice/v1\"><soapenv:Header><Security xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\" xmlns=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\"><UsernameToken><Username>xyzUser</Username><Password>xyzPass</Password></UsernameToken></Security></soapenv:Header><soapenv:Body><v1:OrderSearchRequest><v1:RETAS400OrderNumber>1</v1:RETAS400OrderNumber></v1:OrderSearchRequest></soapenv:Body></soapenv:Envelope>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
        return result;
    }

    public static void main(String[] args) {
        try {
            System.out.println(post()); 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

注意：站点名称、端点、用户名和密码在此消息中被替换为虚拟值。

Answer 1

看不到服务器端，我不知道如何提供帮助。

SOAP-ENV:Server There was a problem with the server, so the message could not proceed.

不幸的是，您需要查看服务器日志以确定发生了什么。

Answer 2

我遇到了完全相同的问题，但是在另一个平台集成上。通过检查正在使用的 WSDL XML Web 服务的 SOAP 操作解决了这个问题，在我的代码中复制并粘贴正确的 SOAP 操作并且它起作用了。

此致。

Answer 3

发生了 2 个级别的操作：1. 应用凭据 2. 发送消息。此两步机制在 SAAJ 中可用。
