我试图测量从我的应用程序调用的某些服务的响应持续时间。
我只需要一个简单的方法，一个粗略的值就足够了，我想我可以简单地从curl_getinfo使用total_time，然后从$response->getInfo()得到这个值，但它总是0。
是否有一些配置或标题，我错过了？
我用

if (!empty($headers)) {
   $httpClient = HttpClient::create(['headers' => [
          'Content-Type' => 'application/json',
          'accept' =>  'application/json',
   ]]);
} else {
   $httpClient = HttpClient::create();
}

if ($method == 'GET') {
   $response = $httpClient->request($method, $url . $pathParams);
} else {
   $response = $httpClient->request($method, $url, ['body' => json_encode($arguments)]);
}

dd($response->getInfo());

字符串
并且输出大多包含空值
