getting error in SOAP client 1

[tlhawkins]

Hey,

I'm a bit of a SOAP retard when it comes to PHP having been spoiled by .NET so please bear with me.

Here is how I'm creating my request:

$SC = new SoapClient('[URL unfurl="true"]http://staging.tgpolicywebsvcs.travelguard.com/tgpolicyservice.asmx?WSDL',[/URL] array("soap_version" => SOAP_1_2));
$returnValue = $SC->__soapCall('getQuoteXML', array('parameters' => $getQuote));

Here is the error I'm getting:
Fatal error: Uncaught SoapFault exception: [soap:Receiver] System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.ArgumentNullException: Value cannot be null. Parameter name: s at System.IO.StringReader..ctor(String s) at System.Xml.XmlDocument.LoadXml(String xml) at Noel.Web.Services.TGPolicyService.GetPolicy(String xml) at Noel.Web.Services.TGPolicyService.GetQuote(String xml) at Noel.Web.Services.TGPolicyService.GetQuoteXML(String data) --- End of inner exception stack trace ---

Any idea what this parameter 's' is that is Null?
I've tried everything I can think of without getting any real difference in the error.

Thanks for any help

this is pretty straightforward. to capture the error you need to use try ... catch blocks in your code.

I suspect that the error in question is indicative that you have not correctly used their API. some further information is available at

http://staging.tgpolicywebsvcs.travelguard.com/tgpolicyservice.asmx?op=GetQuoteXML

 

[tlhawkins]

ok... I've looked at all the data in the WSDL and operation pages. My problem is, I don't know how to reproduce what it's asking for in PHP.

I can call getTypes and getFunctions, those work fine, but when I call getQuote I get errors. So, I know I'm not using the API correctly. I'm not sending the data it wants in the correct format or method. What I'm hoping someone can help with is how I should be sending the call based on the operation pages. It looks like it's just expecting a data field which I tried. I also tried sending it in as "parameters" because a lot of sites said that was how it was done.

Is there any way to tell, from the WSDL or Operation pages what it's expecting me to send?

nope. if you don't have the information already, you need to ask the site owners for their API specification.

 

[tlhawkins]

ah for crying out loud... they gave me an XML snippet of what to send... if I try to send that it fails. If I try to convert the values from that into an array and send them as an array it fails. I've setup this exact API with .Net and it's simple. I really like PHP... sometimes, this isn't one of those times.

post a sample of the .Net code and what they tell you to send in xml. php is just a tool. it will do what you tell it to do and is usually very intuitive.

 

[tlhawkins]

yeah, php is a tool, I feel like I've got my hammer backwards and I'm beating it against my head

Here is how it works in .NET:

Dim webService As New com.travelguard.websvcs.tg_us.TravelGuardUSWebServices 
returnData = webService.GetQuote(sendString)
' sendString holds the xml posted below.

And... the XML

<?xml version="1.0" encoding="utf-16"?>

There has to be an easy way to just send the XML to the SOAP server without all this messyness?

Thanks a ton for all the help

i think you're misusing the methods a bit.

try this instead

$wsdl = '[URL unfurl="true"]http://staging.tgpolicywebsvcs.travelguard.com/tgpolicyservice.asmx?WSDL';[/URL]
$soap = new soapClient($wsdl);
$return = $soap->GetQuote(array('xml'=>$x, 'encoding'=>'utf-16'));

but i suspect the fastest route to success would be to get the api specification from the SOAP host.

 

[tlhawkins]

Oh, really close. That's it, I'm on my way now.
Thanks a TON

>$returnValue = $SC->__soapCall('getQuoteXML', array('parameters' => $getQuote));
Either
[tt]$returnValue=$client->__soapCall('getQuoteXML',array('parameters'=>array([red]'data'[/red]=>$getQuote)));[/tt]
or
[tt]$returnValue = $SC->getQuoteXML(array([red]'data'[/red]=>$getQuote));[/tt]

 

[tsuji]

The reference on the first line is $SC per op's notation, my typos.
[tt]
$returnValue=$[red]SC[/red]->__soapCall('getQuoteXML',array('parameters'=>array('[red]data[/red]'=>$getQuote)));[/tt]
