php - 当传递给 SoapClient 时，关联数组键成为 XML 中的参数

Question

我有一个关联数组:

$params = [
  'trid' => null,
  'merchantCode' => null,
  'paymentMethod' => null,
  'returnUrl' => site_url(null),
  'notificationUrl' => site_url(null),
  'language' => 'null',
  'currency' => 'null',
  'isTestMode' => false,
  'productsXml' => null,
  'needInvoice' => true,

(空值在现实中保存实际值)
当我检查 __getLastRequest 时，我完全丢失了生成的 XML 中的 key 。
SOAP 客户端，

    $soap = new SoapClient(null, $options);
    $soap->__soapCall('Request', $params);
    $request = $soap->__getLastRequest();

请注意，我有一个到端点的非 WSDL 连接。
生成的 XML 的字段值为 <param[keyNum] xsi:type="xsd:typeOfVariable">而不是从关联数组中获得实际的键值， <trid>例如。

<SOAP-ENV:Body><ns1:Request><param0 xsi:type="xsd:string">null</param0><param1 xsi:type="xsd:string">null</param1></Request>

Answer 1

与 PHP 手册的内容相反 says ，好像arguments永远不会被解释为关联数组。
如果我们尝试这个简单的测试:

<?php
$options = ['location'=>'http://localhost/unknown', 'uri'=>'test', 'trace'=>true];
$soap = new SoapClient(null, $options);
try
{
    $soap->__soapCall('Request', ['foo'=>1, 'bar'=>2]);
}
catch(SoapFault $e)
{
    header('Content-type: text/xml');
    echo $soap->__getLastRequest();
}
?>

我们得到:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="test" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
        <ns1:Request>
            <param0 xsi:type="xsd:int">1</param0>
            <param1 xsi:type="xsd:int">2</param1>
        </ns1:Request>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我们看到参数名称被忽略了。
现在，如果我们尝试其他答案的建议(将数组包装在另一个数组中):

<?php
$options = ['location'=>'http://localhost/unknown', 'uri'=>'test', 'trace'=>true];
$soap = new SoapClient(null, $options);
try
{
    $soap->__soapCall('Request', [['foo'=>1, 'bar'=>2]]);
}
catch(SoapFault $e)
{
    header('Content-type: text/xml');
    echo $soap->__getLastRequest();
}
?>

我们得到:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="test" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
        <ns1:Request>
            <param0 xsi:type="ns2:Map">
                <item>
                    <key xsi:type="xsd:string">foo</key>
                    <value xsi:type="xsd:int">1</value>
                </item>
                <item>
                    <key xsi:type="xsd:string">bar</key>
                    <value xsi:type="xsd:int">2</value>
                </item>
            </param0>
        </ns1:Request>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我们看到有一个参数的类型是 Map .那不是我们想要的。
解决方法是使用 SoapParam 类(class):

<?php
$options = ['location'=>'http://localhost/unknown', 'uri'=>'test', 'trace'=>true];
$soap = new SoapClient(null, $options);
try
{
    $soap->__soapCall('Request', [new SoapParam(1, 'foo'), new SoapParam(2, 'bar')]);
}
catch(SoapFault $e)
{
    header('Content-type: text/xml');
    echo $soap->__getLastRequest();
}
?>

现在我们得到了我们想要的:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="test" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
        <ns1:Request>
            <foo xsi:type="xsd:int">1</foo>
            <bar xsi:type="xsd:int">2</bar>
        </ns1:Request>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

请注意，您可以轻松地将关联数组转换为 SOAP 参数，如下所示:

function getSoapParams($params)
{
    $a = [];
    foreach($params as $name=>$value)
        $a[] = new SoapParam($value, $name);
    return $a;
}
