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=newSoapClient ( $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 $Name;
06.publicfunction__construct($parmas){
07.$this->UserId=$parmas[0];
08.$this->Name=$parmas[1];
09.}
10.}
11.$servidorSoap=newSoapServer('testphp.XML',array('uri' => 'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version' => SOAP_1_2 ));
12.$servidorSoap->setClass(Testphp);
13.$servidorSoap->handle();
14.class Testphp {
15.publicfunctionHelloWorld($uid){
16.returnarray('HelloWorldResult'=>"mystring".$uid->{'uname'}.' and '.$uid->{'upassword'});
17.}
18.publicfunctionGetMember($uid){
19.$s=array();
20.for($i=0;$i<$uid->{'uid'};$i++){
21.$s[]=&newMember(array($i, $uid->{'uname'}.'我测试'.$i));
22.}
23.returnarray('GetMemberResult'=>$s);
24.}
25.}
26.?>

到这里应该都看的懂吧

下面是WSDL文件

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：

01.
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);
17.$response=xmlrpc_decode($xml);
18.//输出从RPC服务器端获取的信息
19.print_r($response);
20./**
21.*函数：提供给客户端进行连接XML-RPC服务器端的函数
22.*参数：
23.*$host 需要连接的主机
24.*$port 连接主机的端口
25.*$rpc_server XML-RPC服务器端文件
26.*$request 封装的XML请求信息
27.*返回：连接成功成功返回由服务器端返回的XML信息，失败返回false
28.*/
29.function rpc_client_call($host, $port, $rpc_server, $request) {
30.
$fp=fsockopen($host, $port);
31.
$query="POST $rpc_server HTTP/1.0\nUser_Agent: XML-RPC Client\nHost:".$host."\nContent-Type: text/xml\nContent-Length:".strlen($request)."\n\n".$request."\n";
32.
if(!fputs($fp, $query, strlen($query))) {
33.
$errstr="Write error";
34.
returnfalse;
35.
}
36.
$contents='';
37.
while(!feof($fp)){
38.
$contents .=fgets($fp);
39.
}
40.
fclose($fp);
41.
return $contents;
42.}
43.?>

server.php

代码:

01.
02./**
03.*函数：提供给RPC客户端调用的函数
04.*参数：
05.*$method 客户端需要调用的函数
06.*$params 客户端需要调用的函数的参数数组
07.*返回：返回指定调用结果
08.*/
09.function rpc_server_extendedping($method, $params) {
10.
$title=$params[0];
11.
$server=$params[1];
12.
$rss=$params[2];
13.
//中间的判断,成功返回$XML_RPC_String
14.
$XML_RPC_String=array('flerror'=>false,'message'=>'Thanks for the ping.');
15.
return $XML_RPC_String;
16.}
17.function rpc_server_ping($method, $params) {
18.
$title=$params[0];
19.
$server=$params[1];
20.
//中间的判断,成功返回$XML_RPC_String
21.
$XML_RPC_String=array('flerror'=>false,'message'=>'Thanks for the ping.');
22.
return $XML_RPC_String;
23.}
24.//产生一个XML-RPC的服务器端
25.$xmlrpc_server=xmlrpc_server_create();
26.//注册一个服务器端调用的方法rpc_server，实际指向的是rpc_server_extendedping函数
27.xmlrpc_server_reGISter_method($xmlrpc_server,"weblogUpdates.extendedPing","rpc_server_extendedping");
28.xmlrpc_server_register_method($xmlrpc_server,"weblogUpdates.Ping","rpc_server_ping");
29.//接受客户端POST过来的XML数据
30.$request=$HTTP_RAW_POST_DATA;
31.//print_r($request);
32.//执行调用客户端的XML请求后获取执行结果
33.$xmlrpc_response=xmlrpc_server_call_method($xmlrpc_server, $request,null);
34.//把函数处理后的结果XML进行输出
35.header('Content-Type: text/xml');
36.echo $xmlrpc_response;
37.//销毁XML-RPC服务器端资源
38.xmlrpc_server_destroy($xmlrpc_server);
39.?>

类写的，有BUG

WebService的最常用的两种方法算是写齐了。
