使用SoapClient

我想从<Version>元素中获取嵌套在WSDL的<service>块内的文本。有问题的WSDL是Ebay的交易 api。有问题的片段看起来像这样:

<wsdl:service name="eBayAPIInterfaceService">
    <wsdl:documentation>
        <Version>941</Version>
    </wsdl:documentation>
    <wsdl:port binding="ns:eBayAPISoapBinding" name="eBayAPI">
        <wsdlsoap:address location="https://api.ebay.com/wsapi"/>
    </wsdl:port>
</wsdl:service>

我目前正在这样做:

$xml = new DOMDocument();
$xml->load($this->wsdl);
$version = $xml->getElementsByTagName('Version')->item(0)->nodeValue;

这有效,但我想知道是否有一种方法可以使用PHP的SOAP扩展本地获取它?

我在考虑以下内容会起作用,但事实并非如此:

$client = new SoapClient($this->wsdl);
$version = $client->eBayAPIInterfaceService->Version;

使用常规SoapClient无法执行您想要的操作。最好的办法是扩展SoapClient类并抽象出这个要求以获得版本。

请注意file_get_contents未缓存,因此它将始终加载WSDL文件。另一方面,SoapClient缓存WSDL,因此您必须自己处理它。

或许看看NuSOAP。您将能够修改代码以满足您的目的,而无需加载WSDL两次(当然您也可以修改SoapClient,但那是另一个冠军;)

namespace Application;

use DOMDocument;

class SoapClient extends \SoapClient {
    private $version = null;

    function __construct($wsdl, $options = array()) {
        $data = file_get_contents($wsdl);

        $xml = new DOMDocument();
        $xml->loadXML($data);
        $this->version = $xml->getElementsByTagName('Version')->item(0)->nodeValue;

        // or just use $wsdl :P
        // this is just to reuse the already loaded WSDL
        $data = "data://text/plain;base64,".base64_encode($data);
        parent::__construct($data, $options);
    }

    public function getVersion() {
        return is_null($this->version) ? "Uknown" : $this->version;
    }
}

$client = new SoapClient("http://developer.ebay.com/webservices/latest/ebaysvc.wsdl");
var_dump($client->getVersion());

您是否尝试过simplexml_load_file?当我需要用php解析XML文件时,为我工作。

<?php

$file = "/path/to/yourfile.wsdl";

$xml = simplexml_load_file($file) or die ("Error while loading: ".$file."\n");

echo $xml->service->documentation->Version;

//if there are more Service-Elements access them via index
echo $xml->service[index]->documentation->Version;

//...where index in the number of the service appearing
//if you count them from top to buttom. So if "eBayAPIInterfaceService"
//is the third service-Element
echo $xml->service[2]->documentation->Version;
