我可以使用PHP的SoapClient来解析SOAP响应，而无需发出HTTP请求吗？

Question

I'm currently dealing with an archaic payment processor that makes connecting to their service as hard as possible (including a custom client SSL cert, with a password, plus basic HTTP Auth after that). Long story short, I can't use SoapClient to make the request, but I have been able to do it with cURL.

I now have the response in a string, can I use SoapClient to parse it? I'd rather not have to parse it manually as a regular XML, since I'd have to duplicate a lot of functionality, like throwing a sensible exception when finding a <SOAP:Fault> , for example.

Answer 1

No, you can't.

(just answering this for posterity. Based on the lack of evidence to the contrary, you apparently can't use SoapClient to parse a SOAP response you already have)

Answer 2

您可以使用SoapClient context选项定义上下文，以告诉SoapClient使用SSL证书等。可以使用带有很多选项的 stream_context_create创建上下文

Answer 3

Let's for a second imagine you had called SoapClient::__doRequest() and it returned your XML SOAP response into a variable called $response .

<?php

   //LOAD RESPONSE INTO SIMPLEXML
   $xml = simplexml_load_string($response);

   //REGISTER NAMESPACES
   $xml->registerXPathNamespace('soap-env', 'http://schemas.xmlsoap.org/soap/envelope/');
   $xml->registerXPathNamespace('somenamespace', 'http://www.somenamespace/schema/');
   //...REGISTER OTHER NAMESPACES HERE...

   //LOOP THROUGH AND GRAB DATA FROM A NAMESPACE
   foreach($xml->xpath('//somenamespace:MessageHeader') as $header)
   {
      echo($header->xpath('//somenamespace:MyData')); 
   }

   //...ETC...

?>

That is just some example/pseudo code (not tested and won't work as-is). My point is that you manually acquired the SOAP response so now all you have to do is parse it. SimpleXML is one solution you could use to do that.
