不要让Laravel / PHP等待python脚本完成

Question

Current setup

I currently have a controller class called HomeController.php creates a request for the details the user enters in a form as well as saving other details (Which is not part of this problem).

This request is then sent to another controller class Jobcontroller.php which runs the API, careerjet and returns urls

The problem

I have to manually need to visit another page to run an the API and get the results, then having to execute the python scripts. IE:

website.co.uk/output -> URL 1 , URL 2 , URL 3
exec(script1.py)
exec(script2.py)
exec(script3.py)

What i'm trying to achieve

I do not want to do this of course, and need everything to be automated. Meaning, if the user clicks submit , the api code will immediately run and then the python scripts and it shouldn't affect the front-end usability speed. (They don't have to linger on the same page, waiting for the last job to finish).

I looked at queues implementation for this - and it seems that it only runs when theres no other requests.

This is more of an architecture type of question, but you can try these options:

1. Create a Separate Python Application and communicate via an API

If synchronous operation is mandatory, you may want to have your python scripts be executable via an API. Simply host your scripts via something like Flask.

When Laravel sends an API request to the Flask application, it will kick off the script, and return the result via the HTTP API.

2. Execute the Job in a Queue

So basically same flow as above, but actually create a Laravel Job that communicates to this Flask Application in the background . The user can continue about their business in the Laravel application, when the Job is complete, you can update your database, send a notification, whatever.

3. Execute the Python Script via a PHP shell command

I don't recommend this approach for a long term solution, but you could have PHP execute a shell command that kicks off your python script.

Having the script communicate back to the PHP application could be a total pain in the ass. But it's possible.
