PHP SOAP实现WebService

第一种：WSDL模式
Client.php客户端请求文件
http://localhost/soap/Wsdl/wsdl.php?wsdl 修改为自己目录的对应路径 ?wsdl 必须带着否则会报错

<?php $client = new SoapClient("http://localhost/soap/Wsdl/wsdl.php?wsdl",array('soap_version'=> SOAP_1_2)); try{ $result = $client->test(); echo $result; }catch (SoapFault $f){ echo "Error Message: {$f->getMessage()}"; } ?>

SoapDiscovery.class.php 核心类

<?php
 /** * @package SoapDiscovery 核心 * @author 囚鸟先生 * @copyright Copyright (c) 2013 * @access public **/
class SoapDiscovery {
    private $class_name = '';
    private $service_name = '';

    /** * SoapDiscovery::__construct() SoapDiscovery class Constructor. * * @param string $class_name * @param string $service_name **/
    public function __construct($class_name = '', $service_name = '') {
        $this->class_name = $class_name;
        $this->service_name = $service_name;
    }

    /** * 获取WSDL * * @return string **/
    public function getWSDL() {
        if (empty($this->service_name)) {
            throw new Exception('No service name.');
        }
        $headerWSDL = "<?xml version=\"1.0\" ?>\n";

        }

        $class = new ReflectionClass($this->class_name);

        if (!$class->isInstantiable()) {
            throw new Exception('Class is not instantiable.');
        }

        $methods = $class->getMethods();

        $portTypeWSDL = '<portType name="'.$this->service_name.'Port">';

        $messageWSDL = '';
        foreach ($methods as $method) {
            if ($method->isPublic() && !$method->isConstructor()) {
                $portTypeWSDL.= '<operation name="'.$method->getName()."\">\n".'<input message="tns:'.$method->getName()."Request\" />\n<output message=\"tns:".$method->getName()."Response\" />\n</operation>\n";

                $messageWSDL.= '<message name="'.$method->getName()."Request\">\n";
                $parameters = $method->getParameters();

            }

        //返回一个格式化字符串
        return sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>');
    }

    /** * 返回 WSDL * * @return string **/
    public function returnWSDL() {
        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>";
    }
}

?>

wsdl.php 处理文件

<?php

require_once './yourCode.php';
ini_set('soap.wsdl_cache_enabled','0');    //关闭WSDL缓存

    //打开WSDL
if (isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD']=='POST') {
    $url='http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['PHP_SELF'].'?wsdl';
    $servidorSoap = new SoapServer($url);
    $servidorSoap->setClass('YourCode');
    $servidorSoap->handle();
}else{
    require_once './SoapDiscovery.class.php';
    // 创建WSDL
    $disco = new SoapDiscovery('YourCode','Solsoft_YourCode');
        header("Content-type: text/xml");
    if (isset($_SERVER['QUERY_STRING']) && strcasecmp($_SERVER['QUERY_STRING'],'wsdl')==0) {
        echo $disco->getWSDL();
    }else {
        echo $disco->returnWSDL();
    }
}

?>

yourCode.php 自定义的代码，必须为一个类，类名在wsdl.php 中使用，注意对应修改。

<?php
/** * @package YourCode * @author 囚鸟先生 * @access public **/
class YourCode {

    /** * YourCode::test(); Returns server timestamp. * * @return string **/
    public function test() {
            return time();
    } 
}

说明：

client.php 客户端请求文件
http://localhost/soap/Wsdl/wsdl.php?wsdl 修改为自己目录的对应路径 ?wsdl 必须带着否则会报错

在项目中和其他公司java程序员做接口，他们那边只会Web Services来做接口，之后整理该扩展，分享一下。

client.php

<?php
    try {
        $client = new SOAPClient(null, array(
            'location' => 'http://localhost/NoWsdlSoap/server.php', // 设置server路径
            'uri' => 'http://localhost/NoWsdlSoap/server.php',

        echo $client->__soapCall('test', array()); // 间接调用server方法
    } catch (SOAPFault $e) {
        print $e->getMessage();
    }

server.php

<?php

    // 服务器验证

    require("soapHandle.class.php"); // 处理请求的class

    try{
        $server = new SOAPServer(null, array('uri'=>'http://localhost/NoWsdlSoap/server.php'));
