Send XML with php via message

Question

I know that there are a number of similar issues on SO, but I tried to integrate with all the solutions and, it seems, could not get it to work. I am trying to send xml directly to a web service and get a response. Technically, I am trying to connect to the framework, documentation, for which you can find in the upper right corner of the this page in the documentation. I only mention this because I know a lot that the term SOAP is very much in their xml, and that can make a difference. Anyway, I want to send xml to some kind of url and get a response.

So, if I had the following

$xml = "<?xml version='1.0' encoding='utf-8'?> <soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'> <soap:Body> <GetRatingEngineQuote xmlns='http://tempuri.org/'> <request> <CustomerId>0</CustomerId> <!-- Identifier for customer provided by Freightquote --> <QuoteType>B2B</QuoteType> <!-- B2B / eBay /Freightview --> <ServiceType>LTL</ServiceType> <!-- LTL / Truckload / Groupage / Haulage / Al --> <QuoteShipment> <IsBlind>false</IsBlind> <PickupDate>2010-09-13T00:00:00</PickupDate> <SortAndSegregate>false</SortAndSegregate> <ShipmentLocations> <Location> <LocationType>Origin</LocationType> <RequiresArrivalNotification>false</RequiresArrivalNotification> <HasDeliveryAppointment>false</HasDeliveryAppointment> <IsLimitedAccess>false</IsLimitedAccess> <HasLoadingDock>false</HasLoadingDock> <IsConstructionSite>false</IsConstructionSite> <RequiresInsideDelivery>false</RequiresInsideDelivery> <IsTradeShow>false</IsTradeShow> <IsResidential>false</IsResidential> <RequiresLiftgate>false</RequiresLiftgate> <LocationAddress> <PostalCode>30303</PostalCode> <CountryCode>US</CountryCode> </LocationAddress> <AdditionalServices /> </Location> <Location> <LocationType>Destination</LocationType> <RequiresArrivalNotification>false</RequiresArrivalNotification> <HasDeliveryAppointment>false</HasDeliveryAppointment> <IsLimitedAccess>false</IsLimitedAccess> <HasLoadingDock>false</HasLoadingDock> <IsConstructionSite>false</IsConstructionSite> <RequiresInsideDelivery>false</RequiresInsideDelivery> <IsTradeShow>false</IsTradeShow> <IsResidential>false</IsResidential> <RequiresLiftgate>false</RequiresLiftgate> <LocationAddress> <PostalCode>60606</PostalCode> <CountryCode>US</CountryCode> </LocationAddress> <AdditionalServices /> </Location> </ShipmentLocations> <ShipmentProducts> <Product> <Class>55</Class> <Weight>1200</Weight> <Length>0</Length> <Width>0</Width> <Height>0</Height> <ProductDescription>Books</ProductDescription> <PackageType>Pallets_48x48</PackageType> <IsStackable>false</IsStackable> <DeclaredValue>0</DeclaredValue> <CommodityType>GeneralMerchandise</CommodityType> <ContentType>NewCommercialGoods</ContentType> <IsHazardousMaterial>false</IsHazardousMaterial> <PieceCount>5</PieceCount> <ItemNumber>0</ItemNumber> </Product> </ShipmentProducts> <ShipmentContacts /> </QuoteShipment> </request> <user> <Name> [e-mail] </Name> <Password>password</Password> </user> </GetRatingEngineQuote> </soap:Body> </soap:Envelope>"; 

(I edited this to contain my actual xml, as it may provide some perspective

I want to send it to http://www.someexample.com and get a response. Also, do I need to encode it? I sent xml back and forth from Android many times with Android, and I never had to do this, but that could be part of my problem.

My attempt to send information currently looks like this:

 $xml_post_string = 'XML='.urlencode($xml->asXML()); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://b2b.Freightquote.com/WebService/QuoteService.asmx'); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($ch); curl_close($ch);

If you go to SOAP services, I highly recommend that you learn the basics once and then use this great tool again and again. There are many features that you can use, or you will reinvent the wheel and struggle with creating xml files, analyzing xml files, crashes, etc. Use prepared tools, and your life will be easier, and your code is better (fewer errors).

See http://www.php.net/manual/en/soapclient.soapcall.php#example-5266 how to use the SOAP web service. This is not so hard to understand.

Here is some code how you can analyze webserivce. Then create map types for classes and just send and receive php objects. You can find some tool for creating classes automatically ( http://www.urdalen.no/wsdl2php/manual.php ).

 <?php try { $client = new SoapClient('http://b2b.freightquote.com/WebService/QuoteService.asmx?WSDL'); // read function list $funcstions = $client->__getFunctions(); var_dump($funcstions); // read some request obejct $response = $client->__getTypes(); var_dump($response); } catch (SoapFault $e) { // do some service level error stuff } catch (Exception $e) { // do some application level error stuff } 

If you use the wsdl2php generation tool, everything will be very simple:

 <?php require_once('./QuoteService.php'); try { $client = new QuoteService(); // create request $tracking = new TrackingRequest(); $tracking->BOLNumber = 67635735; $request = new GetTrackingInformation(); $request->request = $tracking; // send request $response = $client->GetTrackingInformation($request); var_dump($response); } catch (SoapFault $e) { // do some service level error stuff echo 'Soap fault ' . $e->getMessage(); } catch (Exception $e) { // do some application level error stuff echo 'Error ' . $e->getMessage(); } 

You can see the generated PHP code for QuoteService.php here: http://pastie.org/8165331

This is a captured message:

Request

 POST /WebService/QuoteService.asmx HTTP/1.1 Host: b2b.freightquote.com Connection: Keep-Alive User-Agent: PHP-SOAP/5.4.17 Content-Type: text/xml; charset=utf-8 SOAPAction: "http://tempuri.org/GetTrackingInformation" Content-Length: 324 <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://tempuri.org/"> <SOAP-ENV:Body> <ns1:GetTrackingInformation> <ns1:request> <ns1:BOLNumber>67635735</ns1:BOLNumber> </ns1:request> </ns1:GetTrackingInformation> </SOAP-ENV:Body> </SOAP-ENV:Envelope>

Answer 2

Firstly, if your code is written this way, I doubt it works as a result of quotes ... You should use a double quote around your xml:

 $my_xml = "<?xml version='1.0' standalone='yes'?> <user> <Name> [e-mail] </Name> <Password>XML</Password> </user>"; 

Alternatively, you can use poster , the firefox addon (maybe it's the equivalent on chrome) to help you with your requests, especially if you use WebServices. This way, you can see if the error is server or client side.

This will help you debug.

Answer 3

I use this command line script to test the SOAP call:

 #!/usr/bin/php <?php //file client-test.php $xml_data = file_get_contents('php://stdin'); $ch = curl_init('http://example.com/server/'); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml')); curl_setopt($ch, CURLOPT_HTTPHEADER, array('SOAPAction', 'MySoapAction')); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); curl_close($ch); print_r($output); 

Usage like this (on the command line): $ client-test.php < yourSoapEnveloppe.xml

In this example, yourSoapEnveloppe.xml is the content of your $xml variable.

You can use stream_context_create and file_get_contents to send xml in the message.

 $xml = "<your_xml_string>"; $send_context = stream_context_create(array( 'http' => array( 'method' => 'POST', 'header' => 'Content-Type: application/xml', 'content' => $xml ) )); print file_get_contents($url, false, $send_context);
