Laravel Guzzle返回错误

Question

I am using laravel 5.5.* and guzzlehttp/guzzle ^6.3 . I have created APIs in the same project ( using laravel api.php ) and consuming API on the same project ( using laravel web.php ) and given throttle 120 per second .

everything was working properly but suddenly got following error while parsing using guzzle

{
    "error": "FatalErrorException",
    "reason": "Allowed memory size of 536870912 bytes exhausted (tried to allocate 266342400 bytes)",
    "code": 1,
    "trace": []
}

Using XAMPP server and memory_limit=2048M . If I access API in the browser it loads fine

Guzzle parsing code below

$client = new Client([
    'base_uri' => env('API_URL'),
    'headers' => ['Content-Type' => 'application/x-www-form-urlencoded; charset=UTF-8'],
    'debug' => true,
]);

Please, someone, help me how I can fix it? even I cleared cache also generated a new key

Answer 1

You have a memory leak on your script that always became from redefining a guzzle in a while loop , try using memory_get_usage to debug the memory usage of your script .

And don't define a class in loops , in your situation that you must use a adapter outside of the loops , like this :

$adapter = new \GuzzleHttp\Adapter\Curl\MultiAdapter(
    new \GuzzleHttp\Message\MessageFactory()
);

while (true) {
    $client = new GuzzleHttp\Client(['adapter' => $adapter]);
    $client->get('http://example.com/guzzle-server');
    echo memory_get_usage() . "\n";
    usleep(20000);
}

EDIT :
You can debug more on memory eaters :

Memprof is a php extension that helps finding those memory-eaters snippets, specially in object-oriented codes. [SOURCE]

EDIT2 :
As the new comments , try to see memory usage via memory_get_usage function before & after calling your api .
