使用 PHP 进行 SOAP API 调用

Question

我已经为此工作了一个星期，但在执行这段代码时遇到了困难。我想通过 SOAP 检索数据并在 PHP 中使用它。我的问题是，我无法发送

RequesterCredentials

。

我将显示 XML 代码，以便大家可以看到我尝试发送的信息，然后是我正在使用的 PHP 代码。

XML 示例代码

POST /AuctionService.asmx HTTP/1.1
Host: apiv2.gunbroker.com
Content-Type: text/xml; charset=utf-8
Content-Length: 200
SOAPAction: "GunBrokerAPI_V2/GetItem"

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Header>
       <RequesterCredentials xmlns="GunBrokerAPI_V2">
         <DevKey>devkey</DevKey>
         <AppKey>appkey</AppKey>
       </RequesterCredentials>
     </soap:Header>
     <soap:Body>
    <GetItem xmlns="GunBrokerAPI_V2">
      <GetItemRequest>
        <ItemID>312007942</ItemID>
        <ItemDetail>Std</ItemDetail>
      </GetItemRequest>
    </GetItem>
  </soap:Body>
</soap:Envelope>

我用来拨打电话的 PHP 代码

$client = new SoapClient("http://apiv2.gunbroker.com/AuctionService.asmx?WSDL");

$appkey = 'XXXXXX-XXXXXX-XXXXXX';
$devkey = 'XXXXXX-XXXXXX-XXXXXX';

$header = new SoapHeader('GunBrokerAPI_V2', 'RequesterCredentials', array('DevKey' => $devkey, 'AppKey' => $appkey), 0);
$client->__setSoapHeaders(array($header));

$result = $client->GetItem('312343077');

echo '<pre>', print_r($result, true), '</pre>';

我得到的结果

stdClass Object
(
    [GetItemResult] => stdClass Object
    (
        [Timestamp] => 2012-11-07T18:17:31.9032903-05:00
        [Ack] => Failure
        [Errors] => stdClass Object
            (
                [ShortMessage] => GunBrokerAPI_V2 Error Message : [GetItem]
                // You must fill in the 'RequesterCredentialsValue'
                // SOAP header for this Web Service method.
                [ErrorCode] => 1
            )
// The rest if just an array of empty fields that
// I could retrieve if I wasn’t having problems.

我不确定问题是我发送 SoapHeaders 的方式还是我误解了语法。我该如何解决它？

Answer 1

使用对象代替标题的关联数组：

$obj = new stdClass();

$obj->AppKey = $appkey;
$obj->DevKey = $devkey;

$header = new SoapHeader('GunBrokerAPI_V2', 'RequesterCredentials', $obj, 0);

您可能面临的下一个问题将是在

GetItem

电话中。您还需要一个对象，包装在关联数组中：

$item = new stdClass;
$item->ItemID = '312343077';
$item->ItemDetail = 'Std';

$result = $client->GetItem(array('GetItemRequest' => $item));
