I am new to SOAP WSDL FUNCTIONS. I have a client who has been given a wsdl file from a company that deals in car testing. My client is a subcontractor for them. They have told us to upload the information about the car plate, category etc and once the details are sent through,There will be a response from server of either success or failure. Kindly assist in this.
Browsing through different information, I tried to do something like below but it is not working
<?php
$data = array('1'=>'value','2'=>'value','3'=>'value','4'='value','5'=>'value');
$wsdl ='http://181.24.80.32/ws/services/servicename';
$client = new SoapClient($wsdl);
$response = $client->servicenamerequest($data);
echo $response->servicenamereturn;
?>
First of all: Go get SoapUI if you are dealing with an unknown Soap service. SoapUI will read the WSDL file and allow you to look at nearly everything related to Soap methods, parameters, and return values (if you dare to make a call to the live service – hopefully there is a sandbox server that does nothing critical).
But SoapUI can help you there by creating a mock service that receives your request and responds with a canned request that you prepared. Here’s how I got from your linked WSDL to a working code example without touching the real service.
Setting up SoapUI
Create a new project in SoapUI and give the location of the WSDL. You might name this project.
SoapUI then reads the contents of the WSDL and creates the project containing all described requests. After that you see what methods the service offers, and what kind of parameters have to go into it, as a tree. Opening this tree will get you to "Request 1" for every method detected, which displays some XML in the free version (paid version is slightly more comfortable with a form to fill) like this (from the
vehiclePassedTestmethod):The questionmarks are where you have to provide data. This request structure has to be created by you using the SoapClient of PHP.
Let’s mock this. Mocking means that SoapUI starts it’s own Soap server that accepts requests. It usually runs on 127.0.0.1:8080. Right-click on the project "PassedVehicleTestService" and select "New MockService". Accept the name, press Ok.
Right-click on the method you want to mock. Select "Add to mock service" and select the created one from the previous step. Answer yes to open the mock response editor. There you see the XML structure of the answer, with question marks for the data that the service will fill out. All the responses from this service allow one answer as a string, so write something nice that will be returned. You can add the other methods to this service later if needed.
Right-click your "MockService 1" and select "Start minimized". This will start the Soap server, it will wait for an incoming request.
Setup PHP SoapClient for the mock.
You need to know two things. First the location of the WSDL. This file contains the address of the real server to be used for the requests, but PHP allows to override this. So the second info you need is the address of the running mock service.
SoapUI displays the address from the WSDL in the request editor. In your case it is
http://181.24.80.32/ws/services/PassedVehicleTestService– the mock service runs onhttp://127.0.0.1:8080/ws/services/PassedVehicleTestService– IP and port is replaced, the path is kept.This leads to the first lines of PHP code:
After that you have a configured SoapClient able to talk to your mock service. If later you want to use the real service, throw the line with "location" out of the array, and keep the other config parameters if you happen to add some.
Talk to the mock
With the client, you can do
$client->nameOfSoapMethod(paramStructure). The parameter structure usually is a mixture of arrays or objects and scalar values like strings. So that’s what I try first:Then I look at SoapUI to see what happens. Output from the php script:
SoapUI says:
That was not the right approach. The array got converted into a string "Array", and was placed as the first parameter. The rest is empty. Nice, because I know that soap calls may accept more that one parameter, and this is one of these services.
This shows up correctly in SoapUI, but the headers are still missing.
Adding SoapHeader to the request
The SoapClient offers a method named
__setSoapHeaders(), and there is a classSoapHeader.The description says that setSoapHeaders() accepts one SoapHeader object or an array of SoapHeader objects. Let’s create one, pass it and see what happens:
PHP says:
Warning: SoapHeader::SoapHeader() expects at least 2 parameters, 0 givenThis works. SoapUI says:
Note the TWO xmlns attributes in the SOAP-ENV:Envelope element. The original request requires the username be in the namespace "tr" – but "tr" is only a shortcut to the string that is defined as "xlmns:tr" – the string behind this is your namespace needed (although it might already work with the real service).
This correctly defines the headers, as you can see:
No two namespaces in the envelope element, and every element is of namespace "ns1". This should work.
Your final code:
