问题
I'm trying to profile the requests made to an API server from a PHP client using Guzzle (v 6).
In the Guzzle 5.3 there is this complete
and before
event handling.
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();
}
}
But how do I do this in v6?
回答1:
Just found it using Middleware. Here's the code.
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;
});
};
};
}
}
And then attach the profiler like this.
$stack = \GuzzleHttp\HandlerStack::create();
$stack->push(Profiler::profile());
$client = new \GuzzleHttp\Client([
'handler' => $stack
]);
