如何描述Guzzle 6的请求？

Question

我正在尝试使用Guzzle(v 6)从PHP客户端分析对API服务器的请求.

在Guzzle 5.3中有这个complete和before事件处理.

class GuzzleProfiler implements SubscriberInterface
{
    public function getEvents()
    {
        return [
            'before'   => ['onBefore'],
            'complete' => ['onComplete']
        ];
    }

    public function onBefore(BeforeEvent $event, $name)
    {
         start_profiling();
    }

    public function onComplete(CompleteEvent $event, $name)
    {
         end_profiling();
    }
}

但是我怎么在v6中这样做呢？

刚刚使用中间件找到了它。这是代码。

class Profiler {

    /**
     * @return callable
     */
    public static function profile() {
        return function(callable $handler) {
            return function(\Psr\Http\Message\RequestInterface $request, array $options) use ($handler) {
                start_profiling();
                return $handler($request, $options)->then(function(\Psr\Http\Message\ResponseInterface $response) use ($token) {
                    end_profiling();
                    return $response;
                });
            };
        };
    }
}

然后像这样附加分析器。

$stack = \GuzzleHttp\HandlerStack::create();
$stack->push(Profiler::profile());
$client = new \GuzzleHttp\Client([
   'handler' => $stack
]);
