JAVA调用PHP SOAP服务方法

JAVA调用PHP SOAP服务

WebService即是一种跨平台的远程调用方法。一方提供服务，另一方使用服务。传输协议是HTTP，而传输的数据则是XML格式的数据。

它有两种方式，WSDL和SOAP。目前仅提及SOAP。

1.PHP提供SOAP服务

定义一个类，它里面有加、减和除三种操作

 

<?php class Operator{
    public function add($x,$y){
        return $x+$y;
    }
    public function substract($x,$y){
        return $x-$y;
    }
    public function divide($x,$y){
        return $x/$y;
    }
}
?>

使用PHP SOAP API，提供SOAP服务。（需要开启SOAP EXTENSION）

 

<?php require("Operator.php");
$server = new SoapServer(null,array('uri' => "http://localhost:8089"));
$server->setClass("Operator");
$server->handle();
?>

假设提供服务的php为index.php

2.JAVA使用PHP提供的SOAP服务

 

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.Node;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
public class Main {
    public void testSOAP(String opename,int x,int y){
        String url = "http://localhost:8089/index.php";
        SOAPConnectionFactory soapConnectionFactory = null;
        SOAPConnection soapConnection = null;
        MessageFactory messageFactory = null;
        SOAPMessage soapMessage = null;
        SOAPPart soapPart = null;
        SOAPEnvelope soapEnvelope = null;
        SOAPBody body = null;
        try{
            //建立连接
            soapConnectionFactory = SOAPConnectionFactory.newInstance();
            soapConnection = soapConnectionFactory.createConnection();
            messageFactory = MessageFactory.newInstance();
            soapMessage = messageFactory.createMessage();
            soapPart = soapMessage.getSOAPPart();
            soapEnvelope = soapPart.getEnvelope();

            //设置调用的webservice方法，及传参
            body = soapEnvelope.getBody();
            SOAPElement element = body.addChildElement(soapEnvelope.createName(opename));
            element.addChildElement("in0").addTextNode(String.valueOf(x));
            element.addChildElement("in1").addTextNode(String.valueOf(y));
            soapMessage.saveChanges();

            //获取返回值
            SOAPMessage reply = soapConnection.call(soapMessage,url);
            soapPart = reply.getSOAPPart();
            soapEnvelope = soapPart.getEnvelope();
            body = soapEnvelope.getBody();
            Node returnvalue = (Node) body.getChildElements().next();

            if (returnvalue != null) {
                  if (returnvalue.getChildNodes().item(0).getNodeName().equals("return")) {
                      List<hashmap>> ReturnArray = new ArrayList<hashmap>>();
                      for (int i=0;i<returnvalue.getchildnodes string key="returnvalue.getChildNodes().item(0).getChildNodes().item(i).getNodeName();" value="returnvalue.getChildNodes().item(0).getChildNodes().item(i).getNodeValue();" system.out.println else returned ex ex.printstacktrace try soapconnection.close catch e todo auto-generated block e.printstacktrace public static void main args main.testsoap>
