PHP - SWA (Ek ile SOAP) işlemek için SoapClient genişletiliyor

Question

Bir Java SOAP hizmetinden SWA yanıtlarını işlemeye çalışıyorum. Bu SWA yanıtında, XML'in sonuna bazı MIME başlıklarıyla eklenen bir ikili ek (ler) bulunur. Bağımlılık gereksinimi sınırlamaları için WSO2'yi kullanamıyorum.

Herhangi bir yardım çok takdir edilecektir!

kullanın bunun için bir MIME parser ile bir şeyler yapmak yanıtını bölmek + üst sınıf SoapClient + gibi StdObj en dönmek için. Oradan oldukça basit:

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); 
      } 
     } 
    } 
} 

daha düzgün the spec uygulamak istiyorsanız, SABUN XML karşı MIME ekleri maç gerekecektir.
