PHP : set client base URL with singleton - php

Question

So, I want to create a client base URL with singleton.
This is my GuzzleClient.php which is containing the base URL
<?php
use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
class GuzzleClient {
public static function getClient()
{
static $client = null;
if (null === $client)
{
$client = new Client([
'base_url' => 'http://localhost:8080/task_manager/v1/',
]);
}
return $client;
}
private function __construct()
{}
}
And this one is where I should put the base url
require_once 'GuzzleClient.php';
class CardTypeAPIAccessor
{
private $client;
public function __construct($client)
{
$this->client = $client;
}
public function getCardTypes() {
$cardTypes = array();
try
{
//this is where base URL should be
$response = $client->get('admin/card/type',
['headers' => ['Authorization' => $_SESSION['login']['apiKey']]
]);
$statusCode = $response->getStatusCode();
// Check that the request is successful.
if ($statusCode == 200)
{
$error = $response->json();
foreach ($error['types'] as $type)
{
$cardType = new CardType();
$cardType->setId($type['card_type_id']);
$cardType->setCategory($type['category']);
array_push($cardTypes, $cardType);
}
}
}
}
}
I stuck with how to put the method in GuzzleClient into this code.
Thanks

I'm creating an abstract class for my webservices that send requests. The instance of guzzle is created in a singleton file:
use Guzzle\Http\Client;
class GuzzleSingleton
{
private static $_instance = null;
private static $baseUrl = '';
public static function getBaseUrl(): string
{
return self::$baseUrl;
}
private static function setBaseUrl($baseUrl): void
{
self::$baseUrl = $baseUrl;
}
public static function getInstance(string $apiUrl, ?int $apiPort, string $apiSuffix): ?Client
{
if (is_null(self::$_instance)) {
self::buildApiUrl($apiUrl, $apiPort, $apiSuffix);
self::$_instance = new Client(self::getBaseUrl());
} else {
self::buildApiUrl($apiUrl, $apiPort, $apiSuffix);
self::$_instance->setBaseUrl(self::getBaseUrl());
}
return self::$_instance;
}
private static function buildApiUrl(string $apiUrl, ?int $apiPort, string $apiSuffix): void
{
$apiDns = rtrim($apiUrl, '/');
$urlApi = (!is_null($apiPort)) ? sprintf('%s:%d', $apiDns, $apiPort) : $apiUrl;
$urlApi .= $apiSuffix;
self::setBaseUrl($urlApi);
}
}
My abstract class:
abstract class AbstractWebservice
{
public function __construct(string $apiUrl, ?int $apiPort, ?string $apiSuffixUrl, Session $session)
{
$this->setApiUrl($apiUrl);
$this->setApiPort($apiPort);
$this->setApiSuffixUrl($apiSuffixUrl);
$this->session = $session;
$this->buildFactory();
}
public function buildFactory(): void
{
$this->guzzleWs = GuzzleSingleton::getInstance($this->getApiUrl(), $this->getApiPort(), $this->getApiSuffixUrl());
}
public function sendRequest(string $endpoint, ?array $body, ?array $options, string $method)
{
$request = $this->guzzleWs->createRequest($method, $endPoint, self::$headers, $body, $options);
return $request->send();
}
}

inharit GuzzleClient class into CardTypeAPIAccessor, and check if $client is notinstanceof GuzzleClient then assign access object into $this->client
class CardTypeAPIAccessor extends GuzzleClient
{
private $client;
public function __construct($client)
{
if($client instanceof GuzzleClient){
$this->client = $client
}else{
$this->client = parent::getClient();
}
}
}
