原生 PHP SoapClient 类不支持多部分消息(并且在所有 WS-* 事务中受到严格限制),我也认为 PHP 编写的库 NuSOAP 和 Zend_Soap 都不能处理这种类型SOAP 消息。
我能想到两种解决方案:
扩展 SoapClient 类并覆盖 SoapClient::__doRequest() 方法以获取实际响应字符串,然后您可以随心所欲地对其进行解析。
class MySoapClient extends SoapClient
{
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
$response = parent::__doRequest($request, $location, $action, $version, $one_way);
// parse $response, extract the multipart messages and so on
}
}
虽然这可能有点棘手 - 但值得一试。
为 PHP 使用更复杂的 SOAP 客户端库。我想到的第一个也是唯一一个是WSO2 WSF/PHP,它具有 SOAP MTOM、WS-Addressing、WS-Security、WS-SecurityPolicy、WS-Secure Conversation 和 WS-ReliableMessaging,但代价是必须安装原生 PHP 扩展.

尽管这个答案已经在这里给出了很多,但我已经整理了一个通用的解决方案,记住,XML 可以在没有包装器的情况下出现。
class SoapClientExtended extends SoapClient
{
/**
* Sends SOAP request using a predefined XML
*
* Overwrites the default method SoapClient::__doRequest() to make it work
* with multipart responses.
*
* @param string $request The XML content to send
* @param string $location The URL to request.
* @param string $action The SOAP action. [optional] default=''
* @param int $version The SOAP version. [optional] default=1
* @param int $one_way [optional] ( If one_way is set to 1, this method
* returns nothing. Use this where a response is
* not expected. )
*
* @return string The XML SOAP response.
*/
public function __doRequest(
$request, $location, $action, $version, $one_way = 0
) {
$result = parent::__doRequest($request, $location, $action, $version, $one_way);
$headers = $this->__getLastResponseHeaders();
// Do we have a multipart request?
if (preg_match('#^Content-Type:.*multipart\/.*#mi', $headers) !== 0) {
// Make all line breaks even.
$result = str_replace("\r\n", "\n", $result);
// Split between headers and content.
list(, $content) = preg_split("#\n\n#", $result);
// Split again for multipart boundary.
list($result, ) = preg_split("#\n--#", $content);
}
return $result;
}
}
这仅在您使用选项 trace => true 初始化 SoapClientExtended 时有效。

使用 S. Gehrig 的第二个想法在这里效果很好。
在大多数情况中,您只需将一条消息打包到 MIME MultiPart 消息中。在这些情况下,会引发“SoapFault 异常:[Client] 看起来我们没有 XML 文档”异常。这里下面的类应该做的很好:
class MySoapClient extends SoapClient
{
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
$response = parent::__doRequest($request, $location, $action, $version, $one_way);
// strip away everything but the xml.
$response = preg_replace('#^.*(<\?xml.*>)[^>]*$#s', '$1', $response);
return $response;
}
}

遵循 PHP 文档中 rafinskipg 的建议:
支持 MTOM 将此代码添加到您的项目中:
<?php
class MySoapClient extends SoapClient
{
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
$response = parent::__doRequest($request, $location, $action, $version, $one_way);
// parse $response, extract the multipart messages and so on
//this part removes stuff
$start=strpos($response,'<?xml');
$end=strrpos($response,'>');
$response_string=substr($response,$start,$end-$start+1);
return($response_string);
}
}
?>
那么你就可以这样做了
<?php
new MySoapClient($wsdl_url);
?>

只是为之前建议的步骤添加更多亮点。您必须收到以下格式的回复
--uuid:eca72cdf-4e96-4ba9-xxxxxxxxxx+id=108
Content-ID: <http://tempuri.org/0>
Content-Transfer-Encoding: 8bit
Content-Type: application/xop+xml;charset=utf-8;type="text/xml"
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body> content goes here </s:Body></s:Envelope>
--uuid:c19585dd-6a5a-4c08-xxxxxxxxx+id=108--
只需使用以下代码(我对正则表达式不太擅长,所以使用字符串函数)
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
$response = parent::__doRequest($request, $location, $action, $version, $one_way);
// strip away everything but the xml.
$response = stristr(stristr($response, "<s:"), "</s:Envelope>", true) . "</s:Envelope>";
return $response;
}

更简单的恕我直言
class SoapClientUnwrappedXml extends SoapClient
{
const SOAP_ENVELOPE_REGEXP = '/^<soap:Envelope[^>]*>(.*)<\/soap:Envelope>/m';
/**
* Sends SOAP request using a predefined XML.
*
* Overwrites the default method SoapClient::__doRequest() to make it work
* with multipart responses or prefixed/suffixed by uuids.
*
* @return string The XML Valid SOAP response.
*/
public function __doRequest($request, $location, $action, $version, $one_way = 0): string
{
$result = parent::__doRequest($request, $location, $action, $version, $one_way);
$headers = $this->__getLastResponseHeaders();
if (preg_match('#^Content-Type:.*multipart\/.*#mi', $headers) !== 0) {
preg_match_all(self::SOAP_ENVELOPE_REGEXP, $result, $resultSanitized, PREG_SET_ORDER, 0);
$result = $resultSanitized[0][0] ?? $result;
}
return $result;
}
}

该代码也适用于我的选项“trace => true”。
