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> <p><br> 运行结果如下:</p> <p>3+4:<br> #text:7<br> 9-7:<br> #text:2<br> 20/4:<br> #text:5</p> <p class="item-note"><br></p></returnvalue.getchildnodes></hashmap></hashmap>
