如何使用SAAJ创建SOAP请求

Question

我知道我可能会问一个琐碎的问题，但无法正确地创建所需的SOAP请求格式。

这类SOAP请求

​

         <?xml version="1.0" encoding="UTF-8" ?>
         <SOAP:Envelope xmlns:SOAP-ENV="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>
         <GetParameter xmlns="http://examples/2001">
		 <request>
         <MonCode xmlns="http://newsite/mon">Latency</MonCode>
		 <TimeFrom xmlns="http://newsite/mon">2016-10-26T11:00</TimeFrom>
		 <TimeTo xmlns="http://newsite/mon">2016-10-26T12:00</TimeTo>
         </request>
		 </GetParameter>
         </SOAP:Body>
         </SOAP:Envelope>

​

我试图通过Java使用SAAJ创建SOAP请求。我发现了一些问题：Java Generate SOAP Envelope

和Working Soap client example

但不明白的是，如何为我的事件创建SOAP请求。

请帮助创建SOAP请求。

附注：试试这段代码

            MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage message = messageFactory.createMessage();
        SOAPPart soapPart = message.getSOAPPart();
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema");
        envelope.addNamespaceDeclaration("xsi", "http://www.w3.org/2001/XMLSchema-instance");
        envelope.addNamespaceDeclaration("soap", "http://schemas.xmlsoap.org/soap/envelop/");

        SOAPBody body = message.getSOAPBody();
        SOAPElement bodyElement = body.addChildElement("GetParameter");
        bodyElement.setAttribute("xmlns", "http://examples/2001");
        bodyElement = body.addChildElement("request");
        SOAPElement paramsElement = bodyElement.addChildElement("MonCode");
        paramsElement.setAttribute("xmlns", "http://newsite/mon");
        paramsElement.addTextNode("Latency");
        paramsElement = bodyElement.addChildElement("TimeFrom");
        paramsElement.setAttribute("xmlns", "http://newsite/mon");
        paramsElement.addTextNode("2016-10-26T11:00");
        paramsElement = bodyElement.addChildElement("TimeTo");
        paramsElement.setAttribute("xmlns", "http://newsite/mon");
        paramsElement.addTextNode("2016-10-26T12:00");

但结果是得到没有值"http://examples/2001“"http://newsite/mon”的SOAP请求。

​

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelop/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Header/>
  <SOAP-ENV:Body>
    <GetParameter xmlns=""/>
    <request>
      <MonCode xmlns="">Latency</MonCode>
      <TimeFrom xmlns="">2016-10-26T11:00</TimeFrom>
      <TimeTo xmlns="">2016-10-26T12:00</TimeTo>
    </request>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

如何解决这个问题？

Answer 1

这段代码解决了任务

​

        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        // Retrieve different parts
        SOAPPart soapPart = soapMessage.getSOAPPart();
        SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();

        soapEnvelope.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema");
        soapEnvelope.addNamespaceDeclaration("xsi", "http://www.w3.org/2001/XMLSchema-instance");

        // Two ways to extract headers
        //    SOAPHeader soapHeader = soapEnvelope.getHeader();
        //    soapHeader = soapMessage.getSOAPHeader();

        // Two ways to extract body
        SOAPBody soapBody = soapEnvelope.getBody();
        soapBody = soapMessage.getSOAPBody();

        // To add some element

        SOAPElement GetParamter=soapBody.addBodyElement(new javax.xml.namespace.QName("http://examples/2001", "GetParamter"));
        GetParamter = GetParamter.addChildElement(new javax.xml.namespace.QName("request"));
        SOAPElement MonCode=GetParamter.addChildElement(new javax.xml.namespace.QName("http://newsite/mon", "MonCode"));
        MonCode.addTextNode("Latency");

        SOAPElement TimeFrom=GetParamter.addChildElement(new javax.xml.namespace.QName("http://newsite/mon", "TimeFrom"));
        TimeFrom.addTextNode("2016-10-26T11:00");

        SOAPElement TimeTo=GetParamter.addChildElement(new javax.xml.namespace.QName("http://newsite/mon", "TimeTo"));
        TimeTo.addTextNode("2016-10-26T12:00");

我认为使用Java并不简单，使用起来也不灵活。

这个解决方案更好

​

   public static void main(String args[]) throws Exception {

        String addr = "http://ws.cdyne.com/emailverify/Emailvernotestemail.asmx";
        String request = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:example=\"http://ws.cdyne.com/\"><SOAP-ENV:Header/><SOAP-ENV:Body>\n" +
                "<example:VerifyEmail><example:email>mutantninja@gmail.com</example:email>\n" +
                "<example:LicenseKey>123</example:LicenseKey></example:VerifyEmail>\n" +

        URL url = null;
        try {
            url = new URL(addr);
        } catch (MalformedURLException e1) {

        connection.setRequestProperty("Connection", "Keep-Alive");
        connection.setRequestProperty("SoapAction", "http://ws.cdyne.com/VerifyEmail");
        connection.setDoOutput(true);
        PrintWriter pw = null;
        try {
            pw = new PrintWriter(connection.getOutputStream());

            e2.printStackTrace();
        }
        pw.write(request);
        pw.flush();

        try {
            connection.connect();
        } catch (IOException e1) {
            // TODO Auto-generated catch block

        }
        BufferedReader rd = null;
        try {
            rd = new BufferedReader(new InputStreamReader(
                    connection.getInputStream()));

        String line;

            while ((line = rd.readLine()) != null)
                respond = line;

        } catch (IOException e1) {

        System.out.println(respond);
    }
