直接使用 SoapClient 我得到一个异常：'看起来我们没有 XML 文档'，但是通过捕获异常并访问$client->__lastReponse()我得到了完整的消息 - 在这里描述：http: //www.w3.org/TR/ SOAP 附件#SOAPMultipart

例子：

什么是解析这个的正确方法，假设二进制数据是我的示例请求，作为文本，我试图通过 SOAP 服务下载。

我想在没有任何额外扩展的情况下解决这个问题，例如WSO2，它似乎具有二进制附件 ( MTOM ) 处理能力，但需要扩展

这绝对不是执行此操作的“正确方法”，但它适用于我的用例：

$client = new SoapClient($wsdl);
try {
  $client->MySoapFunction($argument);
} catch (SoapFault $e)
    {
        if ($e->getMessage() == 'looks like we got no XML document') {
            $response = $client->__getLastResponse();

            $data = $this->_stripSoapHeaders($response);
            return $this->_parseMimeData($data);
        }

protected function _stripSoapHeaders($response)
{
    // Find first occurance of xml tag
    preg_match('/(?<xml><.*?\?xml version=.*>)/', $response, $match);
    $xml = $match['xml'];

    // Strip SOAP http headers, and SOAP XML
    $offset = strpos($response, $xml) + strlen($xml . PHP_EOL);
    return substr($response, $offset);
}
protected function _parseMimeData($data)
{
    // Find MIME boundary string
    preg_match('/--(?<MIME_boundary>.+?)\s/', $data, $match);
    $mimeBoundary = $match['MIME_boundary']; // Always unique compared to content

    // Copy headers to client
    if (preg_match('/(Content-Type: .+?)'.PHP_EOL.'/', $data, $match)) {
        header($match[1]);
    }
    $contentType = $match[1];
    if (preg_match('/(Content-Transfer-Encoding: .+?)'.PHP_EOL.'/', $data, $match)) {
        header($match[1]);
    }

    // Remove string headers and MIME boundaries from data
    preg_match('/(.*Content-Id.+'.PHP_EOL.')/', $data, $match);
    $start = strpos($data, $match[1]) + strlen($match[1]);
    $end = strpos($data, "--$mimeBoundary--");
    $data = substr($data, $start, $end-$start);

    return trim($data, "\r\n");
}

使用上面的代码，我通过 SOAP API 成功下载了 gzip 压缩的二进制文件。
