4. 简单的webservices 例子

1. php 实现 soap

php有两个扩展可以实现web service,一个是NuSoap,一个是php 官方的soap扩展,由于soap是官方的,所以我们这里以soap来实现web service.由于默认是没有打开soap扩展的,所以自己先看一下soap扩展有没有打开。 在soap编写web service的过程中主要用到了SoapClient,SoapServer,SoapFault三个类。

SoapClient类:
这个类用来使用Web services。SoapClient类可以作为给定Web services的客户端。
它有两种操作形式:

  • WSDL 模式
  • Non-WSDL 模式

在WSDL模式中,构造器可以使用WSDL文件名作为参数,并从WSDL中提取服务所使用的信息。

non-WSDL模式中使用参数来传递要使用的信息。


SoapServer类:

这个类可以用来提供Web services。与SoapClient类似,SoapServer也有两种操作模式:WSDL模式和non-WSDL模式。这两种模式的意义跟 SoapClient的两种模式一样。在WSDL模式中,服务实现了WSDL提供的接口;在non-WSDL模式中,参数被用来管理服务的行为。在SoapServer类的众多方法中,有三个方法比较重要。它们是SoapServer::setClass(),SoapServer::addFunction()和SoapServer::handle()。 

PersonInfo.php

<?phpclass PersonInfo{    public function getName($a)    {        return 'My name is wjh ::' . $a;    }}

client.php

<?phptry {    // 1. wsdl 方式    //wsdl方式调用web service    //wsdl方式中由于wsdl文件写定了,如果发生添加删除函数等操作改动,不会反应到wsdl,相对non-wsdl方式,来说不够灵活    //$soap = new SoapClient("http://localhost/Test/MyService/PersonInfo.wsdl");    //2. no-wsdl 方式    //non-wsdl方式调用web service    //在non-wsdl方式中option location系必须提供的,而服务端的location是选择性的,可以不提供    $soap = new SoapClient(null,array('location'=>'http://studio.local/test/server.php','uri'=>'server.php'));    //直接调用,和间接调用(__soapCall)    $result1 = $soap->__soapCall('getName',array('a'=>'hahahah'));    $result2 = $soap->getName('wwwwwwwww');    echo $result1 . '<br/>';    echo $result2;} catch (SoapFault $e) {    echo $e->getMessage();}

server.php

<?phprequire_once ('PersonInfo.php');//1. wsdl 方式//$soap = new SoapServer('PersonInfo.wsdl');//2. no-wsdl 方式//non-wsdl方式中服务端的location是选择性的,可以不提供,客户端 必须提供,即一下两种方式都可以$soap = new SoapServer(null,array("uri"=>"server.php"));//$soap = new SoapServer(null,array('location'=>'http://studio.local/test/server.php','uri'=>'server.php'));$soap->setClass('PersonInfo');$soap->handle();

服务器端代码:

mainservice.php<?php//其中uri相当于java中的命名空间,可以是任何不和别人重合的字符串,第一个参数是wsdl,如果不使用wsdl则使用null,第三个参数表示soap的版本号,目前就两个版本号$wbServer= new SoapServer(null, array('uri'=>'textphpwebservice','soap_version'=>SOAP_1_2));$wbServer->addFunction('sayhello');$wbServer->addFunction('mymin');$wbServer->handle();function sayhello($name){    return "hello ".$name."you are great!";}function mymin($a,$b){    return $a>$b?$b:$a;}exit();?>

客户端代码:

client.php<?phptry{    //第一个参数是wsdl文件,不使用的话用null,location表示webservice服务文件的地址,uri要用要调用的webserivce中的uri一致    $client=new SoapClient(null,array('location'=>'http://studio.local/mainservice.php','uri'=>'textphpwebservice'));    echo $client->sayhello("lijh")."";    echo $client->mymin(100,50)."ccccc";}catch(SoapFault $fault){    echo "fail";}exit();

有 wsdl 情况:

client.php<?phpini_set("soap.wsdl_cache_enabled", "0");header('content-type:text/html;charset=utf-8');$client=new SoapClient("soap.wsdl");$username="lvye";$password="777777";$email="lvye@qq.com";$result=$client->Register("$username","$password","$email");if($result) {   echo 'register ok';} else {    echo 'register no';}
server.php<?phpini_set("soap.wsdl_cache_enabled", "0");include "Action.php";$Server=new SoapServer('soap.wsdl',array('soap_version' => SOAP_1_2));   //创建SoapServer对象$Server->setClass("Action");$Server->handle();
Action.php<?phpclass Action{    private $username;    private $password;    private $email;    public function Register($username,$password,$email) {        $this->username=$username;        $this->password=$password;        $this->email=$email;        if ($this->username == 'aaa' and $this->email == 'bbb' and $this->password =='ccc') {            echo 'ok';            return true;        } else {            echo 'no';            return false;        }    }}

soap.wsdl
