How to use webservices in php using soap

[subrata_ushasi]

Hi all ,

I have a wevservice link say http://abc.com/wscom/MKWebService.rem from where I am trying to return value giving some parameters . The method and parameters are given below.

method : GetInfo

Parameters:

string LicenseID
string password

Return Value:

struct AnswerInt

Now I have two xml files request.xml and response.xml as

//request.xml

<?xml version="1.0" encoding="utf-8"?>
POST /dotnet/lodge.asmx HTTP/1.1
Host: www.messagenet.com.au
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <LodgeMessage xmlns="http://abc.com/wscom/MKWebService.rem">
      <LicenceID>string</LicenceID>
      <password>string</password>
     </LodgeMessage>
  </soap12:Body>
</soap12:Envelope>

//response.xml

<?xml version="1.0" encoding="utf-8"?>
HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <LodgeMessageResponse xmlns="http://abc.com/wscom/MKWebService.rem">
      <LodgeMessageResult>string</LodgeMessageResult>
    </LodgeMessageResponse>
  </soap12:Body>
</soap12:Envelope>

//and php file rpc.php code is :
<php

$client = new SoapClient("http://abc.com/wscom/MKWebService.rem");
    $licenceid="LicenseID";
    $password="password";

    $result = $client->LodgeMessage(array(
        "LicenceID" => $licenceid,
        "password" => $password,
    ));


    $response_arr = objectToArray($result);

    echo "return_code= " . str_replace(";", "", $response_arr["LodgeMessageResult"]);

    function objectToArray($d)
    {
        if (is_object($d))
        {
            $d = get_object_vars($d);
        }

        if (is_array($d))
        {
            return array_map(__FUNCTION__, $d);
        }
        else
        {
            return $d;
        }
    }

?>

Error:
Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load

How to resolve this . Urgent

Subrata

[pritaeas]

Line 38 needs to point to the WSDL, which is usually an URL ending with ?wsdl

[subrata_ushasi]

Pritaeas ,

Thank you for your answer but I tested with ?wsdl but giving the error "Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://abc.com/wscom/MKWebService.rem?wsdl' : Extra content at the end of the document "

Subrata

[pritaeas]

Is it really that link, because that is not a WSDL.

[subrata_ushasi]

No pritaeas that is dummy link

[pritaeas]

Extra content at the end of the document

The above error indicates that the WSDL is invalid.

Hi pritaeas ,
This is based on xml-rpc code . Here is the code and parameters.

method : GetInfo

Parameters:

string LicenseID
string password

Return Value:

struct AnswerInt

and the code is :

<?php
    class XmlRpcClient
    {
        protected $_url;
        protected $_namespace;
        protected $_clients;

        public function __construct( $url, $namespace = '' )
        {
            $this->_url       = (string)$url;
            $this->_namespace = (string)$namespace;
            $this->_clients   = array();
        }

        public function __get( $namespace )
        {
            if( !key_exists( $namespace, $this->_clients ) )
                $this->_clients[ $namespace ] = new XmlRpcClient( $this->_url, strlen( $this->_namespace ) > 0 ? "$this->_namespace.$namespace" : $namespace );

            return $this->_clients[ $namespace ];
        }

        public function __call( $method, array $parameters = array() )
        {
            $request = xmlrpc_encode_request( strlen( $this->_namespace ) > 0 ? "$this->_namespace.$method" : $method, $parameters );
            $context = stream_context_create(
                array(
                    'http' => array(
                        'method'  => "POST",
                        'header'  => "Content-Type: text/xml",
                        'content' => $request
                    )
                )
            );

            $file       = file_get_contents( $this->_url, false, $context );
            $response = xmlrpc_decode( $file );

           /* if( !$response )
                throw new XmlRpcClientException( array( 'faultString' => 'Invalid response from ' . $this->_url ) );

            if( xmlrpc_is_fault( $response ) )
                throw new XmlRpcClientException( $response );*/

            return $response;
        }
    }

    /**
     * Will be thrown by XmlRpcClient on faults.
     */
    class XmlRpcClientException extends Exception
    {
        public function __construct( $response )
        {
            parent::__construct( $response[ 'faultString' ], $response[ 'faultCode' ] );
        }
    }

    $rpc  = new XmlRpcClient( "http://abc.com/wscom/MKWebService.rem " );

    $data = $rpc->tarocards->LicenseAnswerInt("id123","subrata");

    var_dump( $data );

?>

this is not wsdl supported. Now what can I do ?

Subrata

[pritaeas]

Sorry, never used XmlRpcClient before, and no way of testing this. If you use SoapUI, do you get a response then?

[subrata_ushasi]

Pritaeas ,

It is done and code is as follows :

//info.php

<h4>Get license Info</h4>
<table bgcolor="#CCCCCC" cellspacing="0" cellpadding="0">
<form name="GetLicensefrm" action="rpc-process.php" method="post">
    <tr>
       <td>LicensiID:</td>
       <td><input name="licenseid" id="licenseid" /></td>
    </tr>
    <tr>
       <td>Password:</td>
       <td><input type="text"  name="password" id="password"></td>
    </tr>
    <tr>
       <td><input type="Submit" value="Execute" >
           <input type="hidden" name="todo" id="todo" value="getlicense" /></td>
       <td>&nbsp; </td>
    </tr>
</form>
</table>

//rpc-process.php

$varlicenseid=$_POST['licenseid'];
    $varpassword=$_POST['password'];
    $request = xmlrpc_encode_request("GetLicenseInfo", array($varlicenseid,$varpassword));
    $context = stream_context_create(array('http' => array(
      'method' => "POST",
      'header' => "Content-Type: text/xml",
      'content' => $request
    )));
    $file = file_get_contents("http://abc.com/as_com/menWebService.rem", false, $context);
    $response = xmlrpc_decode($file);
    if ($response && xmlrpc_is_fault($response)) 
     {
     trigger_error("xmlrpc: $response[faultString] ($response[faultCode])");
     } 
    else 
        {
        var_dump($response);
    // print_r($response);

      }
    }

but I want the response in xml format and instread of var_dump($response); this will return in struct format.

Subrata

[pritaeas]

Perhaps the webservice has an option to request xml. What do you mean by struct format? Can you show an example response.

[subrata_ushasi]

Two Parameters passed to return struct type xml file.

//output is  :
array
  'Answer' => int -1
  'License' => 
    array
      'product' => string '' (length=0)

  'Comment' => string ''jhgjhgjhg (length=37)

Will soapUI support xml-rpc ?

Will soapUI support xml-rpc ?

Think it does.
