PHP-扩展SoapClient以处理SWA（带附件的SOAP）

我正在尝试处理来自JavaSOAP服务的SWA响应。在这种情况下，SWA响应是附加到XML末尾的二进制附件以及一些MIME头。我不能将WSO2用于依赖项需求限制

任何帮助都将不胜感激

为此使用一个新的方法。从那开始就很简单：

require_once('MimeMailParser.class.php');

class SwADownloadSoapClient extends SoapClient
{
    const ATTACHMENT_DIR = '/path/to/saved/attachments/';

    public function __doRequest(
        $request, $location, $action, $version, $one_way=0
    ) {
        // Issue the SOAP request as SoapClient would normall
        $sResult = parent::__doRequest(
                               $request, $location, $action, $version, $one_way);

        // Handle and parse MIME-encoded messages
        // @note We're not doing much inspection
        //       of the XML payload against the attachments ATM
        //       so not sure how greatly this lives up to the spec
        $sResult = $this->_parseMimeMessage($sResult);

        $oParser = new MimeMailParser();
        $oParser->setText($sResult);

        // Save the attachments
        $aAttachments = $oParser->getAttachments();
        foreach($aAttachments as $oAttachment) {
            $sFile = $oAttachment->filename;
            if($rFp = fopen(self::ATTACHMENT_DIR . $sFile, 'w')) {
                while($sBytes = $attachment->read())
                    fwrite($rFp, $sBytes);
                fclose($rFp);
            }
        }
    }
}

如果您想更正确地实现，您需要将MIME附件与SOAP XML进行匹配。

您应该提供更多信息，我不知道问题出在哪里。这些部分可能是编码的吗？它是有效的XML吗？你分析了吗？您是否尝试了一些错误日志记录？这是一个有趣的黑客风格的尝试，从标题中获取二进制附件。我也朝这个方向走了一段时间。你应该试着用一个函数来解析有效负载，而不是自己用正则表达式。我想知道一个下载和上传的解决方案。

require_once('MimeMailParser.class.php');

class SwADownloadSoapClient extends SoapClient
{
    const ATTACHMENT_DIR = '/path/to/saved/attachments/';

    public function __doRequest(
        $request, $location, $action, $version, $one_way=0
    ) {
        // Issue the SOAP request as SoapClient would normall
        $sResult = parent::__doRequest(
                               $request, $location, $action, $version, $one_way);

        // Handle and parse MIME-encoded messages
        // @note We're not doing much inspection
        //       of the XML payload against the attachments ATM
        //       so not sure how greatly this lives up to the spec
        $sResult = $this->_parseMimeMessage($sResult);

        $oParser = new MimeMailParser();
        $oParser->setText($sResult);

        // Save the attachments
        $aAttachments = $oParser->getAttachments();
        foreach($aAttachments as $oAttachment) {
            $sFile = $oAttachment->filename;
            if($rFp = fopen(self::ATTACHMENT_DIR . $sFile, 'w')) {
                while($sBytes = $attachment->read())
                    fwrite($rFp, $sBytes);
                fclose($rFp);
            }
        }
    }
}
