干预图像make（）不适用于具有较大文件的Laravel控制台内核计划

I have a schedule on my console\kernel.php like this:

$client = new Client;
// I use GuzzleHttp\Client because I can't turn `allow_url_fopen` on
$response = $client->get($image_url);
$body = $response->getBody();
$str = (string) $body;
$image = Image::make($str);

It works well with smaller images (~<200KB), but on files with ~>200KB, the last line crashes without any error logs.

I also tried to get strlen($str) to compare its length with remote file's bytes right before $image = Image::make($str);. it was okay even with a file with 898,357 bytes size and returned 898357.

I tried to use this code in web.php to debug in this way:

$client = new Client;
$response = $client->get($image_url);
$body = $response->getBody();
$str = (string) $body;
$image = Image::make($str);
return  $image->response('jpg', 70);

It works well even with large images, but in this way:

$client = new Client;
$response = $client->get($image_url);
$body = $response->getBody();
$str = (string) $body;
$image = Image::make($str);
return  $image->response();

It just responses for small files and crashes on large files.

Are there any ways to fix this?
