理解多部分消息的PHP SOAP客户端？

原生 PHP SoapClient 类不支持多部分消息（并且在所有 WS-* 事务中都受到严格限制），我也认为 PHP 编写的库 NuSOAP 和Zend_Soap都无法处理此类 SOAP 消息。

我可以想到两种解决方案：

• 扩展类并覆盖该方法以获取实际的响应字符串，然后您可以随心所欲地解析该字符串。SoapClientSoapClient::__doRequest()

  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
      }
  }
  

  这可能有点棘手 - 但值得一试。

• 使用更复杂的 SOAP 客户端库进行 PHP。我脑海中浮现的第一个也是唯一一个是WSO2 WSF/PHP，它具有SOAP MTOM，WS-Addressing，WS-Security Security，WS-SecurityPolicy，WS-Secure Conversation和WS-ReliableMessaging，代价是必须安装本机PHP扩展。

尽管这里已经给出了很多答案，但我已经整理了一个通用的解决方案，请记住，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;
    }
}

这仅在使用选项 初始化 时有效。SoapClientExtendedtrace => true
