Node.js：如何使用 SOAP XML Web 服务

使用Node.js进行SOAP XML Web服务是一个强大的工具，它可以帮助我们与其他系统进行通信和数据交换。本文将介绍如何使用Node.js来构建SOAP XML Web服务，并提供一些案例代码来帮助读者更好地理解。

npm install soap

javascript
const soap = require('soap');
const http = require('http');
const service = {
  MyService: {
    MyPort: {
      MyFunction: function(args) {
        // 处理接收到的请求
        return {
          result: 'Hello ' + args.name
        };
      }
    }
  }
};
const xml = require('fs').readFileSync('myservice.wsdl', 'utf8');
const server = http.createServer(function(request,response) {
  response.end('404: Not Found: ' + request.url);
});
server.listen(8000);
soap.listen(server, '/wsdl', service, xml);

java
import javax.xml.soap.*;
public class SOAPClient {
  public static void main(String[] args) {
    try {
      String endpoint = "http://localhost:8000/wsdl";
      String namespace = "http://example.com/soap";
      String methodName = "MyFunction";
      String soapAction = namespace + "/" + methodName;
      SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
      SOAPConnection soapConnection = soapConnectionFactory.createConnection();
      MessageFactory messageFactory = MessageFactory.newInstance();
      SOAPMessage soapMessage = messageFactory.createMessage();
      SOAPPart soapPart = soapMessage.getSOAPPart();
      SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
      soapEnvelope.addNamespaceDeclaration("", namespace);
      SOAPBody soapBody = soapEnvelope.getBody();
      SOAPElement soapElement = soapBody.addChildElement(methodName);
      SOAPElement soapArgument = soapElement.addChildElement("name");
      soapArgument.addTextNode("John");
      soapMessage.saveChanges();
      SOAPMessage soapResponse = soapConnection.call(soapMessage, endpoint);
      SOAPBody soapResponseBody = soapResponse.getSOAPBody();
      String result = soapResponseBody.getElementsByTagName("result").item(0).getTextContent();
      System.out.println("Result: " + result);
      soapConnection.close();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
