I'm a newbie at CI, and I want to retrieve XML data from web services WebLogic, the server that is located at: http://services.insw.go.id/web-services/nsw?operation.invoke=getListGA . I want to to get the XML response from the server. How should I do this?
I made this function on controllers (resttest.php)
public function getRest()
{
$this->rest->initialize(array('server' => 'http://services.insw.go.id'));
$lartas = $this->rest->get('web-services/nsw',array('operation.invoke' => 'getListGA'),'xml');
die(var_dump($lartas));
}
Sometimes I get an error like "array(0) { }" and if I refresh, I get all HTML view, the same as when I browse to: http://services.insw.go.id/web-services/nsw?operation.invoke=getListGA
Am I wrong, or missing some step, or do you have any suggestion about how to change this code?
It looks as if your webservice is using SOAP (simple object access protocol). This is not REST. You'll want to use PHP's built in Soap extension with the SoapClient class. This way it's easy to post a XML "request" to that page which will return xml results rather than a html view (I assume).
Check Soap the soap extension is loaded on your server
Read about the SoapClient http://php.net/manual/en/class.soapclient.php
See if that webservice offers a WSDL (web service description language) file.
Create an instance of a soap client, using the wsdl and call the function you require.
Simple example from PHP.net
$client = new SoapClient("http://localhost/code/soap.wsdl");
$something = $client->HelloWorld(array());
echo $something->HelloWorldResult;
To get a xml response, you do not need Codeigniter. Specifically it provide WSDL. At http://services.insw.go.id/web-services/nsw you can find the example as
String wsdlUrl = "http://services.insw.go.id:80/web-services/nsw?WSDL";
So the WSDL API would be http://services.insw.go.id:80/web-services/nsw?WSDL
Then you can check this page to see how to install soap for your php.
Then you can get a xml response by the following code:
$client = new SoapClient('http://services.insw.go.id:80/web-services/nsw?WSDL');
//var_dump($client->__getFunctions());
$response = $client->getListGA();
echo $response;
these code do not need Codeigniter.
Note: $client->__getFunctions() will show you all functions that the WSDL support and the parameters the functions need.
Good luck

I'm trying to use the api from this service:
http://messagingws.payamservice.ir/SendSMS.asmx?WSDL
I'm using the php's SOAP client like this:
$client = new SoapClient("http://messagingws.payamservice.ir/SendSMS.asmx?WSDL");
$params=array();
$params['PortalCode']='code';
$params['UserName']='user';
$params['PassWord']='pass';
$params['Mobiles']=array('09123456789');
$params['Messages']=array('test');
$params['FlashSMS']=false;
$params['ServerType']=1;
$response = $client->__soapCall('MultiSMSEngine', array($params));
but I get "empty message" error, when I try with single mode it works correctly so it seems the problem is with Mobiles & Messages parameters that are tns:ArrayOfString
How can I correctly pass an array as tns:ArrayOfString for SOAP ?
thanks
First, you can call the method such as $client->MultiSMSEngine($params) instead of $client->__soapCall('MultiSMSEngine', array($params));.
If you keep your form of call, try $client->__soapCall('MultiSMSEngine', $params);
Finally, to ease you the call to any SOAP Web Service, I strongly advise you to use a WSDL to php generator such as PackageGenerator
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 found this piece of PHP code:
<?php
$client = new SoapClient("http://localhost/code/soap.wsdl");
// Soap call with HelloWorld() method
$something = $client->HelloWorld(array('option1' => 'attribute1'));
// Convert object to array
$array = (array)$something;
I just want to know where soap.wsdl resides or from where we can download soap.wsdl file for PHP.
The location of the WSDL-file is going to depend on the SOAP API you're calling. Check their documentation.
The example code you provided of implies they're working locally, and you're hosting the WSDL on your own, local machine.
Research Edit
Apparently you can use the PHP soap client in non-WSDL mode. This is accomplished by passing in null as the param instead of the location of the wsdl file.
Also relevant, is this other SO result on non-WSDL mode
Im have searched a lot for a code-snippet to autogenerate a SOAP request based on a WSDL in PHP.
We have a 3'rd party vendor creating a huge WSDL ( + related webservices) for us , and I would really like to autogenerate some SOAP-requests in PHP based on that WSDL.
I know of application specific tools like SOAPUI etc - however - I prefer to do the unittesting directly in the PHP-code.
Do you know of any PHP lib to autogenerate SOAP requests based on a WSDL? Or even better, do you have a some code to autogenerate a SOAP request?
use apigenerator.com to generate soap requests
What i would recommend you is to use the soap components of the zend framework.
For example you just setup a soap client using :
$client = new Zend_Soap_Client("url to wsdl file");
//Then you can do what ever request to the server.
$client->helloWorld("Parameter');
// In this example i guess helloWolrd is a server function.
and finally you can have the xml soap request calling:
$request = $client->getLastRequest();
just do: echo $request; and you will see the data.
Remember to change the mime code to xml so you can see the xml in the browser.
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.
