如何在 Laravel 中将数据从一个 class 传输到另一个 class？

Question

目前我正在授权 Amadeus API 并通过服务 class 接收访问令牌，即 Amadeus\Client。多个函数有多个 API 端点，因此我想为单独的端点维护单独的 classes。每个端点都需要访问令牌来处理请求。如何将授权令牌从 Amadeus\Client 传输到 Amadeus\FlightOffersSearch，以便我可以将访问令牌传递到端点的 headers。有人可以帮我吗？

Amadeus\Client

class Client
{
    public function __construct(
        protected string $uri,
        protected string $client_id,
        protected string $client_secret,
        protected string $grant_type,
    ) {}

    public function authorization() {

        $uri = $this->uri;
        $auth_data = array(
            'client_id' => $this->client_id,
            'client_secret' => $this->client_secret,
            'grant_type' =>  $this->grant_type
        );

        $requests_response = Http::asForm()->post($uri, $auth_data);
        $response_body = json_decode($requests_response->body());
        $access_token = $response_body->access_token;

        return $access_token;
}

Amadeus\FlightOffersSearch

class Flight
{
    public function get_flight() {

        if(isset($access_token)){
            $endpoint = 'https://test.api.amadeus.com/v2/shopping/flight-offers';
            $travel_data = array(
                'originLocationCode' => 'BOS',
                'destinationLocationCode' => 'PAR',
                'departureDate' => '2022-06-14',
                'adults' => 2
            );
            $params = http_build_query($travel_data);
            $url = $endpoint.'?'.$params;
            $headers = array('Authorization' => 'Bearer '.$access_token);
        }
    }
}

这比 Laravel 更 PHP 具体。我建议您将客户端设为单例 class，在其中封装所有身份验证逻辑，并在需要时使用静态方法获取客户端实例。

我还强烈建议使用 GuzzleHttp 作为 HTTP 客户端。

类似于这个草稿。

<?php

namespace App;

use GuzzleHttp\Client;

class AmadeusClient
{
    private static $instance;
    private $client;
    private $token;

    public function __construct()
    {
        throw_if(static::$instance, 'There should be only one instance of this class');
        static::$instance = $this;
        $this->client = new Client([
            'base_uri' => 'https://test.api.amadeus.com/v2/',
        ]);
    }

    private function authenticate()
    {
        if (!$this->token) {
            $client_id = env('api_client_id');
            $client_secret = env('api_client_secret');
            $grant_type = env('api_grant_type$a');

            $this->token = ''; // TODO: get authorization token using $this->client;
        }
    }

    public static function getInstance()
    {
        return static::$instance ?: (new static());
    }

    public function get($uri, array $options = [])
    {
        $this->authenticate();
        return $this->client->get($uri, $options);
    }

    public function post($uri, array $options = [])
    {
        $this->authenticate();
        return $this->client->post($uri, $options);
    }
}

然后你会像这样使用它：

$client = AmadeusClient::getInstance();
$client->get('shopping/flight-offers', $options);
