Add simple product to configurable product in Magento 2 by SOAP API

Question

I am tried "configurableProductLinkManagementV1" to add simple product to configurable product.

$result = $soapClient->configurableProductLinkManagementV1addChild(
arr‌​ay('sku' => 'sampleconfigurable','childsku'=>'samplesimpleproduct'));

But, I am getting

PHP Fatal error: Uncaught SoapFault exception: [Sender] SOAP-ERROR: Encoding: object has no 'childSku' property in vendor/zendframework/zend-soap/src/Client.php:1116

=========================================================

<?php
require('vendor/zendframework/zend-server/src/Client.php');
require('vendor/zendframework/zend-soap/src/Client.php');
require('vendor/zendframework/zend-soap/src/Client/Common.php');
$token = 'udctff3sq02h1d90e44xr3nk282khabt';
$wsdlUrl = 'http://127.0.0.1/magento2/soap/default?wsdl&services=configurableProductLinkManagementV1';
$opts = ['http'=> ['header' => "Authorization: Bearer " .$token]];
$context = stream_context_create($opts);
$soapClient  = new \Zend\Soap\Client($wsdlUrl);
$soapClient->setSoapVersion(SOAP_1_2);
$soapClient->setStreamContext($context);
$result = $soapClient->configurableProductLinkManagementV1addChild(array('sku' => 'sampleconfigurable','childsku'=>'samplesimpleproduct'));
?>

Try this:

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

require('vendor/zendframework/zend-server/src/Client.php');
require('vendor/zendframework/zend-soap/src/Client.php');
require('vendor/zendframework/zend-soap/src/Client/Common.php');

$wsdlurl = 'http://127.0.0.1/magento2/index.php/soap/default?wsdl&services=configurableProductLinkManagementV1';
$token = '<your_tokne>';
$opts = ['http' => ['header' => "Authorization: Bearer ".$token]];
$context = stream_context_create($opts);
//$arguments =
$serviceArgs = array(
    'sku' => 'configurable01',
    'childSku' => 'blue01',

);


$soapClient = new \Zend\Soap\Client($wsdlurl);
$soapClient->setSoapVersion(SOAP_1_2);
$soapClient->setStreamContext($context);
$result = $soapClient->configurableProductLinkManagementV1addChild($serviceArgs);
echo "<pre>"; 
print_r($result); 
?>
