laravel 自带的curl请求

$url = "oauth/connect/token";
 try {
                $http = new \GuzzleHttp\Client;
                $response = $http->post($url, ['form_params' => ['grant_type' => $grant_type, 'client_id' => $client_id, 'client_secret' => $client_secret,
                    'redirect_uri' => $redirect_uri, 'code' => $code],]);
            } catch (\Exception $e) {
                Log::info('curl_oauth/connect/token', ['msg' => $e->getMessage(), 'code' => $code, 'time' => date('Y-m-d H:i:s', time())]);
            }

            $total = json_decode((string)$response->getBody(), true);


//参数拼接
['form_params' => ['grant_type' => $grant_type, 'client_id' => $client_id, 'client_secret' => $client_secret,
                    'redirect_uri' => $redirect_uri, 'code' => $code],]

get和post类似
