PHP
To use PHP to invoke web services, you must create the development environment and enable:
-
Soap extension by removing semi-colon (;), which is the comment character, from the line starting with
extension=php_soap.dll -
SSL extension by removing semi-colon (;) from the line starting with
extension=php_openssl.dll
Install and configure any of the available PHP development environments.
-
Simple HTML form that contains a button to submit a request and a text area to display the result.
-
Processing logic that branches based on request type. A POST request calls a web service; any other request clears the value of the text area that contains the result.
-
Processing logic that creates a new instance for the soap client.
-
Construct an array structure that contains the parameters to be passed to the web service.
-
Parse the response as XML and assign to a variable that is displayed in the text area for output.
<?php
// Process POST requests
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
try {
$username ="username";
$password ="password";
// Create new instance for the client
$client = new SoapClient("https://host:port/icCnSetupCreditRulesPublicService/CreditRuleService?wsdl",
array('trace' => 1,
'login' => $username,
'password' => $password));
// Construct the payload to be used to invoke the service.
$params = array(
'findCriteria' => array(
'fetchStart' => '0',
'fetchSize' => '-1',
'filter' => array(
'group' => array(
'upperCaseCompare' => 'false',
'item' => array(
'upperCaseCompare' => 'false',
'attribute' => 'RuleId',
'operator' => '=',
'value' => '300000000851162')
)
),
'excludeAttribute' => 'false'
),
'findControl' => array(
'retrieveAllTranslations' => 'false')
);
// Invoke the service
$response = $client->FindRule($params);
// Process the response. In this example, the content is copied to a variable that is displayed as output
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($client->__getLastResponse());
$dom->formatOutput = TRUE;
$dom->saveXml();
$output = $dom->saveXml();
} catch(Exception $e) {
print "Exception: " . $e->getMessage();
}
} else {
// For GET request, set the variable displayed as output
$output = "";
}
?>
