php编写最简单的webservice

先定义一个类文件 test.class.php

<?php

class CTest

{

       public function __construct()

       {

       }

       
       /**

        *

        * @param string $oParams

        * @return string

        */

       public function Add($oParams)

       {

              $sParams = $oParams->oParams;

              $oParams = json_decode($sParams);

              $a = $oParams->a;

              $b = $oParams->b;

              $c =$a+$b;

              return array('ccc'=>$c);

       }

}

?>

定义一个testServer.php作为WebService

<?php
//error_reporting(E_ALL & ~E_DEPRECATED & ~E_NOTICE); 
include_once('./test.class.php'); 
$server = new SoapServer('wscache/CTest.1.0.wsdl');
$server->setClass('CTest');
$server->handle();
?>

定义WebService 访问文件

<?php
//error_reporting(E_ALL & ~E_DEPRECATED & ~E_NOTICE); 
header("Content-Type: text/html;charset=utf-8");
$client = new SoapClient("http://192.168.1.11:88/testServer.php?wsdl");
$str = '{"a":2,"b":28}';
//调用方法一
//$r = $client->Add(array('oParams'=>$str)); //数组
//调用方法二
$pParams->oParams = $str;
$r = $client->__call('Add',array($pParams));//这个得是对象

$r = object_array($r);

?>

定义xml文件

<?xml version="1.0" encoding="UTF-8" ?>
