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
使用PHP SOAP API,提供SOAP服务。(需要开启SOAP EXTENSION)
"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> ReturnArray = new ArrayList >(); for (int i=0;i
运行结果如下:3+4:
