Sending POST data from Symfony into Yii controller - php

Question

I have Yii2 project. And there I also have api written by Symfony.
In Symfony part I have method in the class which send request to Yii controller.
$buzz = $this->container->get('buzz');
$buzz->getClient()->setVerifyHost(false);
$buzz->getClient()->setVerifyPeer(false);
$buzz->getClient()->setTimeOut(false);
$url = $this->container->getParameter('integra_sync_prices');
$sendResult = $buzz->post($url, array('authorization' => $this->container->getParameter('load_token')), array('products' =>
json_encode($productPrices)));
$resultJson = json_decode($sendResult->getContent(), true);
if (isset($resultJson['error']))
throw new \Exception('Site: '.$resultJson['error'], 500);
class IntegraController extends Controller{
public function actionIndex()
{
Yii::$app->response->format = Response::FORMAT_JSON;
$headers = Yii::$app->request->getHeaders();
foreach ($headers as $key => $value) {
if(strtolower(trim($key)) == 'authorization') {
$token = trim($value[0]);
break;
}
}
$products = json_decode(Yii::$app->request->post('products'));
$post_products = Yii::$app->request->post('products');
if('111' == $token) {
if(isset($post_products) && $products) {
foreach ($products as $product) {
echo $product->price." = ".$product->productId."<br>";
Yii::$app->db->createCommand("UPDATE oc_product SET quantity = '" . (int)$product->quantity . "', price = '" . (float)$product->price . "' WHERE product_id = '" . (int)$product->productId . "'")->execute();
}
$json['success'] = 'complete';
} else {
$json['error'] = 'empty data';
}
} else {
$json['error'] = 'authorization error';
}
Yii::$app->controller->enableCsrfValidation = false;
echo json_encode($json);
}
I expect that data in my database will be updated by this controller. But there in nothing changes.
What do I do wrong? Maybe I should send some another headers? Thanks a lot )
