I'm fairly new to Web Services in PHP, but I've not run into this before. I'm working with another company, who needs to receive a one-way web service request to their SAP system, when they hit our own web service. I've previously never had any problems formatting a string to an XML, and sending it in a request successfully. However, no matter what I've tried, this company is saying that they aren't receiving my requests. I'm not sure if there's something more complicated that I need to do, or some compatability issue that I'm not catching here.
Details:
My Web Service:
Request/Response type
RPC
Theirs:
One-Way
Document/Literal
The Request:
$Client = new SoapClient($wsdl, array("exceptions"=>0, "trace"=>1, "username"=>'user', "password"=>'pass'));
$soapXML = new SoapVar($stringXml, XSD_ANYXML); // $XML being the string that contains the XML
$Client->Request($soapXML); //Operation is void, no need to return to a var
If there's anything that I'm missing here with the request, please any help at all would be greatly appreciated. Been pulling my hair out over this for the past two weeks.

I’m trying to invoke a WCF service (.NET) from PHP. It’s a little more complicated than just using a SoapClient since the service uses a WS2007FederationHttpBinding to authenticate.
Here’s the code I’m using at the moment. I haven’t even added credentials as I’m not sure how, but regardless, I’m not even at the point where I’m getting access denied errors.
$wsdl = "https://slc.centershift.com/sandbox40/StoreService.svc?wsdl";
$client = new SoapClient($wsdl,array(
//'soap_version'=>SOAP_1_2 // default 1.1, but this gives 'Uncaught SoapFault exception: [HTTP] Error Fetching http headers'
));
$params = array();
$params['SiteID'] = 123;
$params['GetPromoData'] = false;
$ret = $client->GetSiteUnitData(array('GetSiteUnitData_Request'=>$params));
print_r($ret);
Which WSDL should I be pointing to?
https://slc.centershift.com/Sandbox40/StoreService.svc?wsdl
Seems to be very short, but includes a reference to (note the wsdl0) https://slc.centershift.com/Sandbox40/StoreService.svc?wsdl=wsdl0
https://slc.centershift.com/Sandbox40/StoreService.svc?singleWsdl
Seems to have everything in it.
Do I need to specify SOAP 1.2? When I do, I get a connection timeout ([HTTP] Error Fetching http headers). When I don’t, the default of SOAP 1.1 is used and I get a [HTTP] Cannot process the message because the content type 'text/xml; charset=utf-8' was not the expected type 'application/soap+xml; charset=utf-8'. Is this because I’m not authenticated yet, or because I’m using the wrong SOAP version?
How to authenticate in PHP? Here’s the corresponding .NET/C# code. Do I need to somehow put these as SOAP headers? Or am I thinking about it all wrong, and I need to do some kind of authentication before I even call the method (from what I read, I’m supposed to get a token back and then use it for all future method calls – I think I see an example of this in an answer here on Stack Overflow.
If I call $client->__getFunctions(), using either WSDL and either SOAP version, I’m getting a valid list of all functions, so I assume either of these is fine and my real issue is the authentication.
Other programmers I’ve talked to had spent time trying to get this to work, but gave up and instead implemented a proxy in .NET. They pass their parameters from PHP to their own unsecured .NET service, which in turn calls this secure service. It works, but seems crazily inefficient to me, and counter-productive, as the purpose of WCF is to support all types of clients (even non-HTTP ones!).
I’ve read How to: Create a WSFederationHttpBinding on MSDN, but it didn’t help.
You can use this URL for WSDL https://slc.centershift.com/Sandbox40/StoreService.svc?singleWsdl. This WSDL has all definitions.
You have to use 1.2 because this webservice works with SOAP 1.2 version. I tried it with 1.1 and 1.2 and both of them gived error. 1.1 is version error, 1.2 is timeout error. I think there is an error at this test server. I used it with svcutil to generate code but it gived error too. Normaly it should get information and generate the code example to call service.
Normally you can add authenticate parameters with SoapHeader or directly add to options in SoapClient consruct (if service authentication is basic authentication). I write below code according to your screenshot. But it gives timeout after long wait.
$wsdl = "https://slc.centershift.com/sandbox40/StoreService.svc?wsdl";
$client = new SoapClient($wsdl,array('trace' => 1,'soap_version' => SOAP_1_2));
$security = array(
'UserName' => array(
'UserName'=>'TestUser',
'Password'=>'TestPassword',
'SupportInteractive'=>false
)
);
$header = new SoapHeader('ChannelFactory','Credentials',$security, false);
$client->__setSoapHeaders($header);
$params = array();
$params['SiteID'] = 100000000;
$params['Channel'] = 999;
try {
$ret = $client->GetSiteUnitData($params);
print_r($ret);
}catch(Exception $e){
echo $e->getMessage();
}
__getFunctions works, because it prints functions defined in WSDL. There is no problem with getting WSDL information at first call. But real problem is communication. PHP gets WSDL, generates required SOAP request then sends to server, but server is not responding correctly. SOAP server always gives a response even if parameters or request body are not correct.
You should communicate with service provider, I think they can give clear answer to your questions.
Having worked with consuming .NET WS from PHP before I believe you would need to create objects from classes in PHP that matches the names that .NET is expecting. The WSDL should tell you the types it is expecting. I hope this assist with your path forward!
If the SOAP call works from a C# application, you could use Wireshark (with the filter ip.dst == 204.246.130.80) to view the actual request being made and then construct a similar request from php.
Check this answer to see how you can do a custom SOAP call.
There's also the option of doing raw curl requests, since it might be easier to build your xml body, but then you would have to parse the response yourself with simplexml.
I have an interesting situation when calling the Shopify API. I use the standard procedure for calling the url and get the data, like this:
define('SHOPIFY_SHOP', 'myteststore.myshopify.com');
define('SHOPIFY_APP_API_KEY', 'xxxx');
define('SHOPIFY_APP_PASSWORD', 'yyy');
$shop_url = 'https://'.SHOPIFY_APP_API_KEY.':'.SHOPIFY_APP_PASSWORD.'#'.SHOPIFY_SHOP;
$response = Requests::get($shop_url.'/admin/products.json');
And I correctly get the response, parse the data and all works great. Now, when I put it to the actual server (Ubuntu 12.04), I noticed a weird message from the Spotify API:
[API] Invalid API key or access token (unrecognized login or wrong password)
I tried creating a new app, but still its the same. So the same file and the same set works on my machine, but not on the server. (only difference in the file is the path to requests library, require_once './Requests/library/Requests.php'; for Linux and require_once '..\Requests\library\Requests.php'; for Windows) As stated, I use the requests library and I assume there has to be some trick where the library (or something else) rewrites the URl and it doesn't get to Shopify correctly.
I tried using CURL with the URL directly, and it works that way as well. Can anyone point me what might be causing this?
Update: I moved to another library which solved the issue, but would like to know what was causing this since I had great experience with Requests up to this point.
I'm starting to use the same lib, and I stumbled upon something relevant right after finding this question:
https://github.com/rmccue/Requests/issues/142#issuecomment-147276906
Quoting relevant part:
This is an intentional part of the API design; in a typical use case,
you won't necessarily need data sent along with a request. Building
the URL for you is just a convenience.
Requests::get is a helper function designed to make GET requests
lightweight in the code, which is why there's no $data parameter
there. If you need to send data, use Requests::request instead
$response = Requests::request( 'http://httpbin.org/get', $headers, $data, Requests::GET, $options );
// GET is the default for type, and $options can be blank, so this can be shortened:
$response = Requests::request( 'http://httpbin.org/get', $headers, $data );
I couldn't figure why is this happening, it appears the Requests library is stripping the parameters from GET requests, so I moved to unirest library and this solved the issue.
I am new to PHP - Started little over a month back with PHP, JS and HTML with a few hours a day.
I have done a lot of homework on this but can't make head and tail out when it comes to implementation. I don't have a hardcore programmer who could sit with me on this, hence here. But I am sure if this question is answered, it would help a lot of newbir and experienced programmers there
The Problem - I can understand the concept of SOAP but cant makout how to make a simple soap request. What would be the steps in PHP.
//php SOAP extention is properly installed
Create a new SOAP client :
$variable = new SoapClient ;
$inputxml = " the input XML file as a string ";
varibale__doRequest($input xml, "string location -??
I have the XML input as a variable.. what location do i specify.. need to enable cache and a cache location ??,...)
Thats the php function i am trying to use - how to use this http://www.php.net/manual/en/soapclient.dorequest.php
// PHP code to obtain response as XML
// How to store the reponse in a variable as a string
Can someone demonstrate a simple SOAP request using PHP on a blog.
I couldnt find one example, all focus on creating SOAP services or SOAP servers.. I just wanna create a SOAP client and make a request in PHP - any detailed laymnas guide - PHP specific ??
This is the SOAP service I am struggling with - Find Company by Keyword at
http://developer.dnb.com/service-directory/sales/16682663-1.html
If someone could write a single post blog explaning the details, would be immensely grateful
PS: Not sure if my frustration is justified, but SOAP and REST concepts make programming sound like Rocket Science.. I have spent over a week, 8 hrs a day, dont have a clear idea on making SOAP requests though I have a fair understanding of the SOAP concept. As far as REST goes, it has me super confused - i don wanna touch that thing here at the moment.
There is the php soap client but you dont HAVE to use it..
you can build your request manually and post it with curl, you can then parse the response as you like.
/**
* Request login body
*/
const REQUEST_LOGIN = '<?xml version="1.0" encoding="utf-8"?>
<env:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.company.com/soap" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding">

SOAP in PHP is a little easier than it seems. If you are looking for a long form tutorial there is a nice one up on DevZone. I would also keep the SoapClient class documentation handy.
The gist of working with Soap
// $endpoint is the callback/uri of the WSDL.
// $options is an array of options.
$client = new SoapClient($endpoint, $options);
You can learn more about he options and endpoint in the details for the constructor.
PHP has some magic methods and __call is one of them. The easiest way to use SOAP is often to just call an available method. For example:
$response = $client->getLoginToken(array(
'siteid' => 'foo',
'secid' => 'bar',
));
In this case getLoginToken is a SOAP method call. The SOAP client sees that it's not a method on the object and passes that as the method on to SOAP. The array passed in is arguments to pass on to the SOAP endpoint as arguments.
I would also checkout the examples on the soapCall page. Best of luck.
I'm quite familiar with using web services in Delphi when I have a WSDL. I simply use the wizard and in a few secs I'm up and running.
I now have a challenge where I'm given a soap interface written in PHP, without any WSDL schema.
The sample given to me for PHP is:
<?php
// The xml to be sent to the webService
$reqest_string = <<<XML
<test_api>
<request>1</request>
</test_api>
XML;
// create web service client
$client = new WSClient(array("to" => "http://api.infax.co.za/edge_api.php"));
// send request to the web service
$reply = $client->request($reqest_string);
// display the responce from the webservice
$xml_str = simplexml_load_string($reply->str);
// display response on screen
echo "Came from server = ".$xml_str->response."<br>";
?>
I've tried just post-ing the xml to the url, but I get a soap error back about a function that does not exist.
Any ideas??
For very simple SOAP web services, it could be easier to follow existing examples / documentation or (if neither is good enough) record the interaction using a HTTP proxy (fiddler2), and then code the communciation using a XML library of your choice.
Hello I'm having problems sending arrays, structs and arrays of structs from PHP to an ASP.NET SOAP server...
Anyone have a sollution for this? I've googled for days and any sollution worked for me. Perphaps I'm forgetting something...
There are examples of my code:
$client = new SoapClient($options);
$pCriteria = new stdClass();
$pCriteria->type=1;
$pCriteria->capacity=4;
//Test 1 (fail):
$resp = $client->GetRooms(array("pCriteria"=>$pCriteria));
//Test 2 (fail):
$resp = $client->GetRooms(array("pCriteria"=>new SoapVar($pCriteria, SOAP_ENC_OBJECT, "TCriteria", "http://www.w3.org/2001/XMLSchema")));
print_r($resp);
I don't know how to code functions that require an array of TCriteria (TCriteria[], TCriteria_Array type) either... i've tried sending the raw array, a SoapVar with SOAP_ENC_ARRAY encoding and TCriteria_Array type, ... but it does not work (the SOAP server becomes unavaiable and needs to be restarted).
I've tried creating classes for the complex types too, instead of stdClass, but not working.
I don't know where's the problem. The server admins cannot help me and I haven't found any sollution over internet. I'm a bit desperate hehe.
Can you help me please? Can you provide samples of code with the three cases (array of simple data, array of struct and struct) ? Thanks!
I had a similar situation with a PHP Soap Client communicating with a .NET Soap Server using WSDL 2.0. Here's one thing I discovered: When passing the information to the server, you must explicitly define the variable as a SoapVar object. So in your example above, change it to:
$pCriteria->type = new SoapVar(1, XSD_INT, 'xsd:int');
Passing an array is similar, essentialy you pass an array of SoapVars:
$pCriteria->type = array(new SoapVar(1, XSD_INT, 'xsd:int'), new SoapVar(2, XSD_INT, 'xsd:int', new SoapVar(3, XSD_INT, 'xsd:int'));`enter code here`
Also, you can use several built-in functions of the SoapClient to get some additional feedback on possible errors.
$client->__getLastRequest() //To display the XML that you sent to the server
$client->__getLastResponse() //to display the XML that is sent in response to your request
If you can get a copy of the expected WSDL format you can use the response from the above commands to determine what is going wrong. Usually you can access this from the URL that you pass to the SoapClient. So, for example, if the WSDL services URL is http://example.com/webservices/wvrgroupservice.asmx?WSDL, enter http://example.com/webservices/wvrgroupservice.asmx to view the functions and expected XML from that server.
