导入此库：

use GuzzleHttp\Client;
use GuzzleHttp\ClientFactory;
use GuzzleHttp\Exception\RequestException;

on __构造用途：

$this->client = new Client([
            "base_uri" => url_base,
            "timeout" => 2,
        ]);

然后呼叫：

$response = $this->client->get(
                    url_base . "/" . url_api_point,
                    ['headers' =>
                        [
                            'Authorization' => "Bearer {$this->token}" /* if have */
                        ]
                    ]
                );
                return json_decode($response->getBody()->getContents(), true, 512, JSON_THROW_ON_ERROR);

尝试这种方式来创建GuzzleClient的一个示例，我目前正在使用一个类似的magento 2.4.4和工程罚款，你不必inyect，on __construct（）

/**
 * @return \GuzzleHttp\Client
 */
public function getClient()
{
    $client = new \GuzzleHttp\Client(["base_uri" => "your url", "verify" => false]);
    return $client;
}
