View Full Version : Soap xml curl Request return empty response or 1

10-30-2012, 11:10 AM
Hi guys,
i'm facing a problem with a web server curl soap call.
The response to my call is always blank if i set CURLOPT_RETURNTRANSFER true or 1 and otherwise if i set CURLOPT_RETURNTRANSFER to false or 0 the response is always 1

If i make any error either in header or in soap request the response is always correct.

I assume my problem is not with the request itself.

I've been creating soap request either via Dom and with a class i wrote for ebay soap api calls. With the same result.
I can paste any part of code.


public function sendRequest($glsCall, $requestBody, $gls_lenght)
//build gls headers using variables passed via constructor as well as the gls call to use
$headers = $this->buildGlsHeaders($glsCall, $gls_lenght);

//initialise a CURL session
$connection = curl_init();

//set the server we are using
curl_setopt($connection, CURLOPT_URL, 'http://weblabeling.gls-italy.com/IlsWebService.asmx');

//Time out
curl_setopt($connection, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($connection, CURLOPT_TIMEOUT, 10);

//set it to return the transfer as a string from curl_exec
curl_setopt($connection, CURLOPT_RETURNTRANSFER, true);

//stop CURL from verifying the peer's certificate
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, false);

//set method as POST
curl_setopt($connection, CURLOPT_POST, true);

//set the XML body of the request
curl_setopt($connection, CURLOPT_POSTFIELDS, $requestBody);

//set the headers using the array of headers
curl_setopt($connection, CURLOPT_HTTPHEADER, $headers);

//Testing the connection
if(curl_exec($connection) === false)
$err = 'Curl error: ' . curl_error($connection);
return $err;
//Send the Request
$response = curl_exec($connection);

//close the connection

//return the response
return $response;


public function buildGlsHeaders($glsCall,$gls_lenght)
$headers = array (
//header soap 1.1
"POST /IlsWebService.asmx HTTP/1.1",
"Host: weblabeling.gls-italy.com",
"Content-Type: text/xml; charset=utf-8",
"Content-Length: " . $gls_lenght,
"SOAPAction: \"http://weblabeling.gls-italy.com/AddParcel\"",

return $headers;
Thanks in advance,

Is this $requestBody a valid soap:envelope? If it is, try just setting the soapAction to run instead.
Any reason why you don't just use the SOAPClient class?

Thanks for your answer.
i've been checked xml/soap file on some online checker, it should be fine, the most told so, some other told not (indicating error in ">" of soap:envelope)

I tried to use soap class as well but the respose from webserver was always bad xml error, so i used my class wich is already tested and working, i'm using for ebay api calls.

I don't understand why if i take something off from the schema, like a child, i get as response a correct answer with error because of xml format error.

If the xml looks correct i got no answer and bad request as well (HTTP/1.1 400 Bad Request header)

That's the question though, is the XML valid and correct? It has to match the schema provided by using the request (see here for the schema doc: http://www.soapuser.com/basics3.html). It doesn't matter if your XML is valid, it has to be correct as well and matching that soap envelop schema in order for the server to understand it.

SOAPClient on the other hand is a matter of giving it a link to the remote wsdl. Then you literally call it if it were a function:

$sc = new SOAPClient('http://asite.com/soap.wsdl');
$result = $sc->AddParcel($not, $sure, $if, $takes, $params);
catch (SOAPException $ex)
print $ex->getMessage();

Way easier to use a soap client.

if i use std class to construct xml

$XMLInfoParcel = new stdClass();
$XMLInfoParcel->Info->SedeGls = $SedeGls;
$XMLInfoParcel->Info->CodiceClienteGls = $CodiceClienteGls;
$XMLInfoParcel->Info->PasswordClienteGls = $PasswordClienteGls;
$XMLInfoParcel->Info->Parcel = new stdClass();
$XMLInfoParcel->Info->Parcel->CodiceContrattoGls = $cod_cont;
$XMLInfoParcel->Info->Parcel->RagioneSociale = $rag_soc;
$XMLInfoParcel->Info->Parcel->Indirizzo = $delivery_indirizzo;
$XMLInfoParcel->Info->Parcel->Localita = $delivery_city;
$XMLInfoParcel->Info->Parcel->Zipcode = $data['delivery_postcode'];
$XMLInfoParcel->Info->Parcel->Provincia = $data['zone_code'];
$XMLInfoParcel->Info->Parcel->Bda = '';
$XMLInfoParcel->Info->Parcel->DataDocumentoTrasporto = '';
$XMLInfoParcel->Info->Parcel->Colli = '1';
$XMLInfoParcel->Info->Parcel->Incoterm = '';
$XMLInfoParcel->Info->Parcel->PesoReale = '1,00';
$XMLInfoParcel->Info->Parcel->ImportoContrassegno = $imp_cont;
$XMLInfoParcel->Info->Parcel->NoteSpedizione = $data['customers_telephone'];
$XMLInfoParcel->Info->Parcel->TipoPorto = 'F';
$XMLInfoParcel->Info->Parcel->Assicurazione = $***_ins;
$XMLInfoParcel->Info->Parcel->PesoVolume = '';
$XMLInfoParcel->Info->Parcel->TipoCollo = $tipo_collo;
$XMLInfoParcel->Info->Parcel->FrancoAnticipata = '';
$XMLInfoParcel->Info->Parcel->RiferimentoCliente = '';
$XMLInfoParcel->Info->Parcel->NoteAggiuntive = '';
$XMLInfoParcel->Info->Parcel->CodiceClienteDestinatario = '';
$XMLInfoParcel->Info->Parcel->Email = '';
$XMLInfoParcel->Info->Parcel->Cellulare1 = $telefono_1;
$XMLInfoParcel->Info->Parcel->Cellulare2 = '';
$XMLInfoParcel->Info->Parcel->ServiziAccessori = '';
$XMLInfoParcel->Info->Parcel->ModalitaIncasso = $mod_inc;

it generates an xml but i'm having problems with the first node

<ns1:AddParcel env:encodingStyle="http://www.w3.org/2003/05/soap-encoding"><param0 xsi:type="enc:Struct"><Info

This param0 have to be changed with XMLInfoParcel for correct structure.

So when i send out the request with soapClient it gives me xml format error

You have me confused here; stdclass won't generate an XML structure. That has to be something that you are doing with it.
What gives you an XML error, the soapclient or the response from the server? You may need to look at their wsdl to verify the structure expected for the parameters as well.

double post, sorry

10-30-2012, 06:26 PM
forget about stdclass i used because i read on an example in php documentation.

anyway now i don't understand what is the correct schema. I have some documentation from webservice where i have xml schema and envelope schema, let me post picture:

what my script generates:


this is the soap part required


this is the string part


It continues and ends with Info closing

Is that last one what the server expects to receive?
When you try using this as a soapclient, what is the code you are using? If its to be formatted as that XML, what does it look like prior to providing it to the soapclient? Also, you can pull the __getLastRequest() off of the soapclient itself to see what is sent to the soapserver. I believe you need to add the trace to the soapclient to do that, so the second param of the soapclient constructor would simply be given array('trace' => 1') or appended if an array is already available.

this is getting tricky. Using curl instead of soapClient i made two call for two different services.

Service A: ListSped works correctly


Service B: AddParcel doesn't work


xml is built in the same way from array in each case and so is curl. I still don't get why in service B doesn't work

Looks to me that its fine and its the data that's no good. You'll have to go through the service's documentation to verify exactly what the structure must be for the parameters you are providing.

Allright, thanks for your help,i will check tomorrow. I will keep you posted!

i checked all data against problems.
All lenghts are correct and < of max allowed.
All field is alfanumeric / numeric as requested.

I'm googling this 400 bad request also if xml is correct to see if anyone experienced something like that.

If you would have any idea about that please just tell me
