Provide API-Client to Controller - php

Question

I am using Laravel to call an external API.
This is my Client:
<?php
use GuzzleHttp\Client;
$client = new Client();
$response = $client->request('POST',
'https://example.org/oauth/token', [
'headers' => [
'cache-control' => 'no-cache',
'Content-Type' => 'application/x-www-form-urlencoded',
],
'form_params' => [
'client_id' => '2',
'client_secret' => 'client-secret',
'grant_type' => 'password',
'username' => 'username',
'password' => 'password',
],
]);
$accessToken = json_decode((string)$response->getBody(),
true)['access_token'];
Now I can use this to fetch something:
<?php
$response = $client->request('GET',
'https://example.org/api/items/index', [
'headers' => [
'Accept' => 'application/json',
'Authorization' => 'Bearer '.$accessToken,
],
]);
So now I don't want to initiate the client on every method again. So maybe there's a cool/Laravel-like way to provide the $client to the controller on specific routes?
I thought about an app service provider or an middleware, but I'd love to see an example :-)

Answer 1

Perhaps you can use singleton? Wrap your implementation in a class lets say YourHttpClient then in your AppServiceProviders register method add:
$this->app->singleton('YourHttpClient', function ($app) {
return new YourHttpClient();
});
Then you should be able to typehint it in your controller constructors like this
class SomeController {
private $client;
public function __construct(YourHttpClient $client) {
$this->client = $client;
}
}
