如何使用Laravel进行异步请求？

Question

In my Laravel 5.4 web app user can request report generation that takes a couple of minutes due to a big amount of data. Because of these he couldn't work with application no more, until report will be generated. To fix this problem I have read about queues in laravel and separated out my report generation code to the job class, but my app still holds until report will be generated. How can I fix that?

To be absolutely clear I will sum up my problem:

1. User make request for report generation (my app absolutely holds at this moment)
2. My app receives POST request in routes and calls a function from the controller class.
3. Controller's function dispatches a job, that should generate report and put it into the client web folder.

By default, Laravel uses the sync queue driver. This driver executes the queued jobs in the same request as the one they are created in. So this won't make any difference.

You should take a look at other drivers and use the Laravel queue worker background process to execute jobs to make sure they don't hold the webrequest from completing.
