PHP教程:WebService最常用的两种方法
國內(nèi)用PHP寫WebService的真的很少,網(wǎng)上資料也沒多少,公司的項(xiàng)目開發(fā)過程中,經(jīng)歷了不少這方面的東西,寫出來以供大家參考(謝謝老農(nóng)提供的WSDL和程序文件)
客戶端
代碼:
01.??
02.header ( "Content-Type: text/html; charset=utf-8" );
03./*
04.* 指定WebService路徑并初始化一個(gè)WebService客戶端
05.*/
06.$ws ="http://soap/soapCspMessage.php?wsdl";
07.$client =new SoapClient ( $ws, array ('trace' => 1, 'uri' => 'http://www.zxsv.com/SoapDiscovery/' ) );
08./*
09.* 獲取SoapClient對(duì)象引用的服務(wù)所提供的所有方法
10.*/
11.echo ("SOAP服務(wù)器提供的開放函數(shù):");
12.echo ('
');
13.var_dump ( $client->__getFunctions () );
14.echo ('
');
15.echo ("SOAP服務(wù)器提供的Type:");
16.echo ('
');
17.var_dump ( $client->__getTypes () );
18.echo ('
');
19.echo ("執(zhí)行GetGUIDNode的結(jié)果:");
20.//$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.?>
服務(wù)端
代碼:
?
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, $uid->{'uname'}.'我測(cè)試'.$i));
22.}
23.return array('GetMemberResult'=>$s);
24.}
25.}
26.?>
到這里應(yīng)該都看的懂吧
下面是WSDL文件
代碼:

這一段就字符串的
那返回?cái)?shù)組的就比較麻煩了,我和老農(nóng)搞了一兩周才發(fā)現(xiàn)是WSDL文件寫錯(cuò)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"/>

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是輸入,最重要的是GetMemberResponse這段,看type=”tns:ArrayOfMember”這里,返回一 個(gè)數(shù)組,WSDL中定義了ArrayOf這個(gè),后面的就簡(jiǎn)單了,ArrayOfMember的類型是type=”tns:Member” ,從name=”Member”得到要返回的數(shù)組,完工。

Ping Service,博客程序提供一種通知機(jī)制,以便在第一時(shí)間將博客的更新信息發(fā)布到提供Ping Service服務(wù)的網(wǎng)站,寫聚合的時(shí)候研究了一下
先看標(biāo)準(zhǔn)吧
這是一個(gè)標(biāo)準(zhǔn)的Ping Service,用XMLRPC來傳數(shù)據(jù)的,注釋寫的這么詳細(xì),代碼說明就不需要了吧,PHP5開啟XMLRPC方法
