PHP Webservice简单实例

这是对上一篇《PHP Webservice知识点笔记》的一个简单实例补充。

• 测试网站目录：http://test.com/testWebservice/

1. server端代码serverHasWsdl.php（WSDL模式）

   <?phpdefine('WSDL_URL','test.wsdl');             //定义WSDL文件路径ini_set('soap.wsdl_cache_enabled', '0');    //关闭WSDL缓存 //WSDL文件不存在时自动创建if(!file_exists(WSDL_URL)){    require_once 'SoapDiscovery.class.php';    $disco = new SoapDiscovery('MyTest', 'test.com'); //SoapDiscovery是网上一个生成wsdl的类    $str = $disco->getWSDL();    file_put_contents(WSDL_URL, $str);}$server = new SoapServer(WSDL_URL); $server->setClass('MyTest');$server->handle();  //测试类class MyTest {        public function addition ($a=0, $b=0){        return $a + $b;    }    }?>

   
   
2. client端代码clientHasWsdl.php（WSDL模式）

   <?php$client = new SoapClient("http://test.com/testWebservice/test.wsdl");try {    $result = $client->addition(100,200);    //$result = $client->__soapCall('addition',array(600,200));    var_dump($result);}catch (SoapFault $f) {    echo "Error Message: {$f->getMessage()}";}?>

   
   
3. server端代码serverNonWsdl.php（non-WSDL模式）

   <?php$server = new SoapServer(null, array('uri'=>'testWebservice','soap_version'=>SOAP_1_2));$server->setClass('MyTest');$server->handle();//测试类class MyTest {        public function addition ($a=0, $b=0){        return $a + $b;    }    }?>

4. client端代码clientNonWsdl.php（non-WSDL模式）

   <?php$client = new SoapClient(null, array('location'=>'http://test.com/testWebservice/serverNonWsdl.php','uri'=>'testWebservice'));try {    $result = $client->addition(200,300);    //$result = $client->__soapCall('addition',array(300,300));    var_dump($result);}catch (SoapFault $f) {    echo "Error Message: {$f->getMessage()}";}?>

5. 通过CURL访问clientCurl.php

   <?php$requestxml = '<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:test.com">   <soapenv:Header/>   <soapenv:Body>      <urn:addition soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">         <a xsi:type="xsd:string">300</a>         <b xsi:type="xsd:string">500</b>      </urn:addition>   </soapenv:Body></soapenv:Envelope>';$ch = curl_init();curl_setopt($ch, CURLOPT_URL, 'http://test.com/testWebservice/serverHasWsdl.php');//curl_setopt($ch, CURLOPT_URL, 'http://test.com/testWebservice/serverNonWsdl.php');curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $requestxml);curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/soap+xml; charset=utf-8", "Content-length: ".strlen($requestxml))); $response = curl_exec($ch);curl_close($ch);echo $response;?>
