PHP企业级应用之WebService

经典里的PHP气氛还是太差了，都是些简单的应用，我来段企业级应用吧，主要是讲PHP5对webservice的一些实现(以下的程序可以被JAVA，NET，C等正常调用)
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:

<?php
header ( "Content-Type: text/html; charset=utf-8" );
/*
* 指定WebService路径并初始化一个WebService客户端
*/
$ws = "http://soap/soapCspMessage.php?wsdl";
$client = new SoapClient ( $ws, array ('trace' => 1, 'uri' => 'http://www.zxsv.com/SoapDiscovery/' ) );
/*
* 获取SoapClient对象引用的服务所提供的所有方法
*/
echo ("SOAP服务器提供的开放函数:");
echo ('<pre>');
var_dump ( $client->__getFunctions () );
echo ('</pre>');
echo ("SOAP服务器提供的Type:");
echo ('<pre>');
var_dump ( $client->__getTypes () );
echo ('</pre>');
echo ("执行GetGUIDNode的结果:");
//$users = $client->GetUsers();
//var_dump($HelloWorld );
$parameters = array('uname'=>'zxsv',"upassword"=>'123');
$out = $client->HelloWorld($parameters);
$datadb = $out->HelloWorldResponse;
var_dump($out);
?>

服务端

代码:

<?php
class Member
{
public $UserId;
public $Name;
public function __construct($parmas){
$this->UserId = $parmas[0];
$this->Name = $parmas[1];
}
}
$servidorSoap = new SoapServer('testphp.xml',array('uri' => 'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version' => SOAP_1_2 ));
$servidorSoap->setClass(Testphp);
$servidorSoap->handle();
class Testphp {
public function HelloWorld($uid){
return array('HelloWorldResult'=>"mystring".$uid->{'uname'}.' and '.$uid->{'upassword'});
}
public function GetMember($uid){
$s=array();
for($i=0;$i<$uid->{'uid'};$i++){
$s[] =&new Member(array($i, $uid->{'uname'}.'我测试'.$i));
}
return array('GetMemberResult'=>$s);
}
}
?>

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
<s:element name="HelloWorld">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="upassword" type="s:string" />
</s:sequence>
</s:complexType>
</s:element>
<s:element name="HelloWorldResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="HelloWorldResult" type="s:string" />
</s:sequence>
</s:complexType>
</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
<s:element name="GetMember">
<s:complexType>
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="uid" type="s:int" />
<s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
</s:sequence>
</s:complexType>
</s:element>
<s:element name="GetMemberResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="GetMemberResult" type="tns:ArrayOfMember" />
</s:sequence>
</s:complexType>
</s:element>
<s:complexType name="ArrayOfMember">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="Member" nillable="true" type="tns:Member" />
</s:sequence>
</s:complexType>
<s:complexType name="Member">
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="UserId" type="s:int" />
<s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" />
</s:sequence>
</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。
