Laravel 5: Performing an asynchronous task
提问by John Bupit
I have the following function where I process an image file of type UploadedFile, give it as a random name, use \Intervention\Imageto store it in different sizes, and then return the image name.
我有以下函数，我处理类型为 的图像文件UploadedFile，将其作为随机名称，用于\Intervention\Image以不同的大小存储它，然后返回图像名称。
The storing part takes lot of time and the request usually times out. It would be great if I could do the processing in a separate thread or process, and return the image name. Here's the code I have:
存储部分需要很多时间，并且请求通常会超时。如果我可以在单独的线程或进程中进行处理并返回图像名称，那就太好了。这是我的代码：
public function storeSnapshots(UploadedFile $image) {
// Generate a random image name.
$imageName = str_random(12) . '.' . $image->getClientOriginalExtension();
// Process the image. Should be done asynchronously.
\Intervention\Image\Facades\Image::make($image)
->heighten(2000, function($constraint) {
$constraint->upsize();
})->save('img/lg/' . $imageName)
->heighten(800)->save('img/md/' . $imageName)
->heighten(120)->save('img/sm/' . $imageName);
// Return the image name generated.
return $imageName;
}
What would be the Laravel way to perform an asynchronous task?

Laravel performs asynchronous tasks via the queue system.
Laravel 通过队列系统执行异步任务。
