你是我最后的希望！我正在尝试将DHL的API评级应用到一个网站上。他们把示例代码发给我，我用演示证书把它放到演示环境中，效果很好。后来他们更改了端点url并将永久凭据发送给我。之后我就不能上班了。我得到以下错误：
SOAP故障！

其中*********我的实际凭证。如果我将url 作为端点
https://wsbexpress.dhl.com/gbl/expressRateBook?wsdl
我得到了SOAP模式作为响应。你能帮我找出问题所在吗？我没有得到正确的回应？
尝试以下选项：
$opts = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
$options = array (
'encoding' => 'UTF-8',
'verifypeer' => false,
'verifyhost' => false,
'soap_version' => SOAP_1_2,
'trace' => 1,
'exceptions' => 1,
'connection_timeout' => 180,
'stream_context' => stream_context_create($opts),
'cache_wsdl' => WSDL_CACHE_NONE,
//'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 1
);
