工作Soap客户端示例 [英] Working Soap client example

问题描述

我正在尝试在JAVA中找到一个带有工作服务的简单（ha）SOAP示例，我似乎找不到任何工作。

I'm trying to find a simple (ha) SOAP example in JAVA with a working service, any I seem to be finding are not working.

我有从这个一个 /chapters/ch03s05.htmlrel =noreferrer>示例但它只是不起作用，它要求我放一个正斜杠，但它在那里并没有发生任何事情。

I have tried this one from this example but it's just not working, it's asking me to put a forward slash in but it's in there and nothing happening.

所以有人知道任何SOAP示例链接，我可以下载/请求和搞乱吗？

So does anyone know any SOAP example links, I can download/request and mess with?

感谢您的帮助。

推荐答案

要在Java中实现简单的SOAP客户端，您可以使用SAAJ框架（它随JSE 1.6及更高版本一起提供）：

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java（SAAJ）主要用于直接处理在幕后发生的SOAP请求/响应消息任何Web服务API。它允许开发人员直接发送和接收soap消息，而不是使用JAX-WS。

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

请参阅下面的一个工作示例（运行它！ ）使用SAAJ进行SOAP Web服务调用。它称为此网络服务。

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

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

        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myNamespace="http://www.webserviceX.NET">
                <SOAP-ENV:Header/>
                <SOAP-ENV:Body>
                    <myNamespace:GetInfoByCity>
                        <myNamespace:USCity>New York</myNamespace:USCity>
                    </myNamespace:GetInfoByCity>
                </SOAP-ENV:Body>
            </SOAP-ENV:Envelope>
            */

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }

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

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);

        soapMessage.saveChanges();

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

        return soapMessage;
    }

}
