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:

<?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();

?>

给出客户端client编码:

<?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));

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

        //生成wsdl文件,将上面的return注释
        $fso = fopen($this->class_name . ".wsdl", "w");
        fwrite($fso, sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>'));
    }

    /**
     * SoapDiscovery::getDiscovery() Returns discovery of WSDL.
     * 
     * @return string
     * */
    public function getDiscovery() {
        return "<?xml version=\"1.0\" ?>\n<disco:discovery xmlns:disco=\"http://schemas.xmlsoap.org/disco/\" xmlns:scl=\"http://schemas.xmlsoap.org/disco/scl/\">\n<scl:contractRef ref=\"http://" . $_SERVER['SERVER_NAME'] . ':' . $_SERVER['SERVER_PORT'] . $_SERVER['PHP_SELF'] . "?wsdl\" />\n</disco:discovery>";
    }

}

?>

我们可以使用这个文件来生成需要的wsdl文件:

<?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();

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:

<?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();
?>

python的client端:

import SOAPpy
server = SOAPpy.SOAPProxy("www.test.com/soap/server.php")
print server.Add(1,2)
