  • PHP教程:WebService最常用的两种方法

     国内用PHP写WebService的真的很少,网上资料也没多少,公司的项目开发过程中,经历了不少这方面的东西,写出来以供大家参考(谢谢老农提供的WSDL和程序文件)

      客户端

      代码:

    01.  
      
    02.header ( "Content-Type: text/html; charset=utf-8" );
      
    03./*
      
    04.* 指定WebService路径并初始化一个WebService客户端
      
    05.*/
      
    06.$ws ="http://soap/soapCspMessage.php?wsdl";
      
    07.$client =new SoapClient ( $ws, array ('trace' => 1, 'uri' => 'http://www.zxsv.com/SoapDiscovery/' ) );
      08./*
      
    09.* 获取SoapClient对象引用的服务所提供的所有方法
      
    10.*/
      
    11.echo ("SOAP服务器提供的开放函数:");
      
    12.echo ('
    '
    );
      13.var_dump ( $client->__getFunctions () );
      
    14.echo ('
    '
    );
      15.echo ("SOAP服务器提供的Type:");
      
    16.echo ('
    '
    );
      17.var_dump ( $client->__getTypes () );
      
    18.echo ('
    '
    );
      19.echo ("执行GetGUIDNode的结果:");
      
    20.//$users = $client->GetUsers();
      
    21.//var_dump($HelloWorld );
      
    22.$parameters =array('uname'=>'zxsv',"upassword"=>'123');
      23.$out = $client->HelloWorld($parameters);
      
    24.$datadb = $out->HelloWorldResponse;
      
    25.var_dump($out);
      
    26.?>

      服务端

      代码:

    01.  
      
    02.class Member
      
    03.{
      
    04.public $UserId;
      
    05.public $Name;
      
    06.public function __construct($parmas){
      
    07.$this->UserId = $parmas[0];
      
    08.$this->Name = $parmas[1];
      
    09.}
      
    10.}
      
    11.$servidorSoap =new SoapServer('testphp.XML',array('uri' => 'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version' => SOAP_1_2 ));
      12.$servidorSoap->setClass(Testphp);
      
    13.$servidorSoap->handle();
      
    14.class Testphp {
      
    15.public function HelloWorld($uid){
      
    16.return array('HelloWorldResult'=>"mystring".$uid->{'uname'}.' and '.$uid->{'upassword'});
      17.}
      
    18.public function GetMember($uid){
      
    19.$s=array();
      
    20.for($i=0;$i<$uid->{'uid'};$i++){
      21.$s[] =&new Member(array($i, $uid->{'uname'}.'我测试'.$i));
      22.}
      
    23.return array('GetMemberResult'=>$s);
      24.}
      
    25.}
      
    26.?>

      到这里应该都看的懂吧

      这里有返回的两个字段,一个是返回字符串,这个很好理解

    01.<s:element name="HelloWorld">
    02.<s:complexType>
    03.<s:sequence>
    04.<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string"/>
    05.<s:element minOccurs="0" maxOccurs="1" name="upassword" type="s:string"/>
    06.</s:sequence>
    07.</s:complexType>
    08.</s:element>
    09.<s:element name="HelloWorldResponse">
    10.<s:complexType>
    11.<s:sequence>
    12.<s:element minOccurs="0" maxOccurs="1" name="HelloWorldResult" type="s:string"/>
    13.</s:sequence>
    14.</s:complexType>
    15.</s:element>

      这一段就字符串的

      那返回数组的就比较麻烦了,我和老农搞了一两周才发现是WSDL文件写错了,看下面的一段

    01.<s:element name="GetMember">
    02.<s:complexType>
    03.<s:sequence>
    04.<s:element minOccurs="1" maxOccurs="1" name="uid" type="s:int"/>
    05.<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string"/>
    06.</s:sequence>
    07.</s:complexType>
    08.</s:element>
    09.<s:element name="GetMemberResponse">
    10.<s:complexType>
    11.<s:sequence>
    12.<s:element minOccurs="0" maxOccurs="1" name="GetMemberResult" type="tns:ArrayOfMember"/>
    13.</s:sequence>
    14.</s:complexType>
    15.</s:element>
    16.<s:complexType name="ArrayOfMember">
    17.<s:sequence>
    18.<s:element minOccurs="0" maxOccurs="unbounded" name="Member" nillable="true" type="tns:Member"/>
    19.</s:sequence>
    20.</s:complexType>
    21.<s:complexType name="Member">
    22.<s:sequence>
    23.<s:element minOccurs="1" maxOccurs="1" name="UserId" type="s:int"/>
    24.<s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string"/>
    25.</s:sequence>
    26.</s:complexType>

      第一段GetMember是输入,最重要的是GetMemberResponse这段,看type=”tns:ArrayOfMember”这里,返回一 个数组,WSDL中定义了ArrayOf这个,后面的就简单了,ArrayOfMember的类型是type=”tns:Member” ,从name=”Member”得到要返回的数组,完工。

      Ping Service,博客程序提供一种通知机制,以便在第一时间将博客的更新信息发布到提供Ping Service服务的网站,写聚合的时候研究了一下

      先看标准吧

      这是一个标准的Ping Service,用XMLRPC来传数据的,注释写的这么详细,代码说明就不需要了吧,PHP5开启XMLRPC方法

      client.php

      代码:

    02.$host ='zxsv';
      03.$port =80;
      
    04.$rpc_server ='/test/xmlrpc_server.php';
      05.$title ='zxsv';
      06.$server ='http://zxsv/test/';
      07.$rss ='http://zxsv/test/rss.php';
      08.//WeblogUpdates.Ping方法
      
    09.$Ping = xmlrpc_encode_request('weblogUpdates.Ping', array($title, $server ));
      10.//weblogUpdates.extendedPing方法
      
    11.$extendedPing = xmlrpc_encode_request('weblogUpdates.extendedPing', array($title, $server, $rss ));
      12.//调用rpc_client_call函数把所有请求发送给XML-RPC服务器端后获取信息
      
    13.$response = rpc_client_call($host, $port, $rpc_server, $Ping);
      
    14.$split='';
      15.$xml = explode($split, $response);
      
    16.$xml = $split . array_pop($xml);
