php soap示例

今天简单讲一个使用广发的webservice，在php中对这个服务支持的很完备，但是个人更喜欢使用python来实现soap等webservice，pyton对于数据处理例如xml，和数据传输交换等有很多优势，那么下面就简单给一下使用wsdl文件的小例子。
先给出服务端server的编码：[shell]
<?php

/**
* Description of package
*
* @author gavin
*/
class package {
//deliver package
public function shipping($a,$b){
return json_encode(func_get_args());
}
//update expressNo
public function expressNoUpdate(){

}
}

//使用SoapDiscovery.class生成wsdl的时候下面生成soap客户端的都要注释掉，也就是全部注释掉
$server = new SoapServer('package.wsdl', array('soap_version' => SOAP_1_2));
//不使用wsdl文件的时候
//$server = new SoapServer(null, array('uri' => 'abcd'));
$server->setClass("package");
$server->handle();

?>[/shell]
给出客户端client编码：[shell]
<?php
//ini_set('soap.wsdl_cache_enabled', "0");
$soap = new SoapClient('http://www.test.com/apiErp/package.wsdl');
//var_dump($soap);
var_dump($soap->shipping(1,2));[/shell]
其中wsdl文件的生成如果你是用zend studio的话，可以直接使用它生成，但那是如果不是这里有个办法就是使用一个类，这是一个外国哥们儿写的：
SoapDiscovery.class.php[shell]

?>[/shell]
我们可以使用这个文件来生成需要的wsdl文件：[shell]
<?php

include('package.php');
include("SoapDiscovery.class.php");

$disco = new SoapDiscovery('package', 'soap'); //第一个参数是类名（生成的wsdl文件就是以它来命名的），即Service类，第二个参数是服务的名字（这个可以随便写）。
$disco->getWSDL();[/shell]
在生成的时候，注意server端的编码中生成soap客户端的部分需要注释掉。

下面给一个python远程调用php函数并返回结果的示例,php作为服务端:[shell]
<?php
class service {

public function HelloWorld() {
return "Hello";
}

public function Add($a, $b) {
return $a + $b;
}

}

//使用SoapDiscovery.class生成wsdl的时候下面生成soap客户端的都要注释掉
$server = new SoapServer('service.wsdl', array('soap_version' => SOAP_1_2));
//$server = new SoapServer(null, array('uri' => 'abcd'));
$server->setClass("service");
$server->handle();
?>[/shell]
python的client端:[python]
import SOAPpy
server = SOAPpy.SOAPProxy("www.test.com/soap/server.php")
print server.Add(1,2)[/python]
