How to return search API response from controller in magento 2?

Question

I have an API(ukvehicledata) for search using registration id.

I want to integrate with magento 2.2

I am getting response in controller as JSON format. I have converted it into an array.

Now I want to return the response to the search result page.

I am using below code:

<?php 
public function execute()
 {
 $this->layerResolver->create(Resolver::CATALOG_LAYER_SEARCH);
 /* @var $query \Magento\Search\Model\Query */
 $query = $this->_queryFactory->get();
 $storeId = $this->_storeManager->getStore()->getId();
 $query->setStoreId($storeId);
 $queryText = $query->getQueryText();
 if ($queryText != '') {
 // Init cURL session
 $curl = curl_init();
 // Set API Key
 $ApiKey = "675D83AAC4C8-E9C9-E9C9-E9C9-675D83AAC4C8";
 // Construct URL String
 $url = "https://uk1.domainname.co.uk/api/datapackage/%s?v=2&api_nullitems=1&key_vrm=%s&auth_apikey=%s";
 $url = sprintf($url, "VehicleData", $queryText, $ApiKey); // Syntax: sprintf($url, "PackageName", "VRM", ApiKey);
 // Note your package name here. There are 5 standard packagenames. Please see your control panel > weblookup or contact your account manager
 // Create array of options for the cURL session
 curl_setopt_array($curl, array(
 CURLOPT_URL => $url,
 CURLOPT_RETURNTRANSFER => true,
 CURLOPT_MAXREDIRS => 10,
 CURLOPT_SSL_VERIFYPEER => false,
 CURLOPT_TIMEOUT => 30,
 CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
 CURLOPT_CUSTOMREQUEST => "GET"
 ));
 // Execute cURL session and store the response in $response
 $response = curl_exec($curl);
 // If the operation failed, store the error message in $error
 $error = curl_error($curl);
 // Close cURL session
 curl_close($curl);
 // If there was an error, print it to screen. Otherwise, unserialize response and print to screen.
 if ($error) {
 echo "cURL Error: " . $error;
 } else {
 //$respons = json_decode($response, true); // For demonstration purposes - Unserialize response & dump array contents to screen
 $results = json_decode($response, true);
 $responsee = $results->Response->DataItems->VehicleRegistration;
 /*echo '<ul>';
 foreach ($responsee as $key => $value) {
 echo '<li>'.$key.' => '.$value.'</li><br/>';
 }
 echo '</ul>';*/
 } else {
 $this->getResponse()->setRedirect($this->_redirect->getRedirectUrl());
 }
 }

• Aditya Shah: you can use search Criteria

Answer 1

I have an API(ukvehicledata) for search using registration id.

API(ukvehicledata)

you can use search Criteria using registration id

 http://<magento_host>/rest/V1/YOUR_API/?
 searchCriteria[filter_groups][0][filters][0][field]=registration_id&
 searchCriteria[filter_groups][0][filters][0][value]={VALUE}&
 searchCriteria[filter_groups][0][filters][0][condition_type]‌​=eq

method type : GET

The system creates an array, as shown in the following pseudo-code.

searchCriteria => [
 'filterGroups' => [
 0 => [
 'filters' => [
 0 => [
 'field' => 'registration_id',
 'value' => 'YOUR VALUE',
 'condition_type' => 'eq'
 ]
 ]
 ]
