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:
#text:7
9-7:
#text:2
20/4:
#text:5
